Safety Belts

Safety Belts: They Are for EveryoneThis part of the manual tells you how to usesafety belts properly. It also tells you some thingsyou should not do with safety belts.

{CAUTION:

Do not let anyone ride where he or shecannot wear a safety belt properly. If youare in a crash and you are not wearing asafety belt, your injuries can be muchworse. You can hit things inside thevehicle or be ejected from it. You can beseriously injured or killed. In the samecrash, you might not be, if you arebuckled up. Always fasten your safetybelt, and check that your passengers’belts are fastened properly too.

19

Page 20: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

{CAUTION:

It is extremely dangerous to ride in acargo area, inside or outside of a vehicle.In a collision, people riding in these areasare more likely to be seriously injured orkilled. Do not allow people to ride in anyarea of your vehicle that is not equippedwith seats and safety belts. Be sureeveryone in your vehicle is in a seat andusing a safety belt properly.

Your vehicle has indicators to remind you and yourpassengers to buckle your safety belts. See SafetyBelt Reminder Light on page 196 and PassengerSafety Belt Reminder Light on page 197.

In most states and in all Canadian provinces, thelaw says to wear safety belts. Here is why:They work.

You never know if you will be in a crash. If you dohave a crash, you do not know if it will be abad one.

A few crashes are mild, and some crashes can beso serious that even buckled up, a personwould not survive. But most crashes are inbetween. In many of them, people who buckle upcan survive and sometimes walk away. Withoutbelts they could have been badly hurt or killed.

After more than 40 years of safety belts invehicles, the facts are clear. In most crashesbuckling up does matter... a lot!

Why Safety Belts WorkWhen you ride in or on anything, you go as fastas it goes.

Take the simplest vehicle. Suppose it is just aseat on wheels.

Put someone on it.

With safety belts, you slow down as the vehicledoes. You get more time to stop. You stopover more distance, and your strongest bonestake the forces. That is why safety beltsmake such good sense.

Questions and Answers AboutSafety Belts

Q: Will I be trapped in the vehicle after anaccident if I am wearing a safety belt?

A: You could be — whether you are wearing asafety belt or not. But you can unbuckle asafety belt, even if you are upside down. Andyour chance of being conscious during andafter an accident, so you can unbuckle and getout, is much greater if you are belted.

Q: If my vehicle has airbags, why should Ihave to wear safety belts?

A: Airbags are supplemental systems only; sothey work with safety belts — not instead ofthem. Every airbag system ever offeredfor sale has required the use of safety belts.Even if you are in a vehicle that has airbags,you still have to buckle up to get the mostprotection. That is true not only in frontalcollisions, but especially in side and othercollisions.

Q: If I am a good driver, and I never drive farfrom home, why should I wear safety belts?

A: You may be an excellent driver, but if you arein an accident — even one that is not yourfault — you and your passengers can be hurt.Being a good driver does not protect youfrom things beyond your control, such as baddrivers.

Most accidents occur within 25 miles (40 km)of home. And the greatest number ofserious injuries and deaths occur at speeds ofless than 40 mph (65 km/h).

Safety belts are for everyone.

How to Wear Safety Belts ProperlyThis part is only for people of adult size.

Be aware that there are special things to knowabout safety belts and children. And thereare different rules for smaller children and babies.If a child will be riding in your vehicle, seeOlder Children on page 43 or Infants and YoungChildren on page 46. Follow those rules foreveryone’s protection.

First, you will want to know which restraintsystems your vehicle has.

We will start with the driver position.

Driver Position

Lap-Shoulder BeltThe driver has a lap-shoulder belt. Here is how towear it properly.

1. Close and lock the door.

2. Adjust the seat so you can sit up straight. Tosee how, see “Seats” in the Index.

3. Pick up the latch plate and pull the belt acrossyou. Do not let it get twisted.The lap-shoulder belt may lock if you pull thebelt across you very quickly. If this happens,let the belt go back slightly to unlock it.Then pull the belt across you more slowly.

4. Push the latch plate into the buckle untilit clicks.

25

Page 26: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Be sure to use the correct buckle whenbuckling your lap-shoulder belt. If you find thatthe latch plate will not go fully into thebuckle, see if you are using the buckle for thecenter passenger position.Pull up on the latch plate to make sure it issecure. If the belt is not long enough,see Safety Belt Extender on page 42.Make sure the release button on the buckle ispositioned so you would be able to unbucklethe safety belt quickly if you ever had to.

5. Move the shoulder belt height adjuster to theheight that is right for you. Improper shoulderbelt height adjustment could reduce theeffectiveness of the safety belt in a crash. SeeShoulder Belt Height Adjustment on page 33.

6. To make the lap part tight, pull up on theshoulder belt.It may be necessary to pull stitching on thesafety belt through the latch plate to fullytighten the lap belt on smaller occupants.

26

Page 27: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

The lap part of the belt should be worn low andsnug on the hips, just touching the thighs. Ina crash, this applies force to the strong pelvicbones. And you would be less likely to slide underthe lap belt. If you slid under it, the belt wouldapply force at your abdomen. This could causeserious or even fatal injuries. The shoulderbelt should go over the shoulder and across thechest. These parts of the body are best ableto take belt restraining forces.

The safety belt locks if there is a sudden stopor crash.

A: The shoulder belt is worn under the arm. Itshould be worn over the shoulder at all times.

{CAUTION:

You can be seriously injured if you wearthe shoulder belt under your arm. In acrash, your body would move too farforward, which would increase the chanceof head and neck injury. Also, the beltwould apply too much force to the ribs,which are not as strong as shoulderbones. You could also severely injureinternal organs like your liver or spleen.

Safety Belt Use During PregnancySafety belts work for everyone, including pregnantwomen. Like all occupants, they are more likelyto be seriously injured if they do not wearsafety belts.

A pregnant woman should wear a lap-shoulderbelt, and the lap portion should be worn as low aspossible, below the rounding, throughout thepregnancy.

The best way to protect the fetus is to protect themother. When a safety belt is worn properly, itis more likely that the fetus will not be hurtin a crash. For pregnant women, as for anyone,the key to making safety belts effective is wearingthem properly.

Right Front Passenger PositionTo learn how to wear the right front passenger’ssafety belt properly, see Driver Position on page 25.

The right front passenger’s safety belt works thesame way as the driver’s safety belt — exceptfor one thing. If you ever pull the shoulder portionof the belt out all the way, you will engage thechild restraint locking feature. If this happens, justlet the belt go back all the way and start again.

When the safety belt is not in use, slide the latchplate up so that it is stored on the safety beltstitching, near the guide loop.

If your vehicle has a center passenger position, besure to use the correct buckle when bucklingyour lap-shoulder belt. If the latch plate will not gofully into the buckle, see if you are using thebuckle for the center passenger position.

Center Front Passenger Position

Lap BeltIf your vehicle has a front bench seat, someonecan sit in the center position.

When you sit in the center front seating position,you have a lap safety belt, which has no retractor.To make the belt longer, tilt the latch plate andpull it along the belt.

To make the belt shorter, pull its free end asshown until the belt is snug.

Buckle, position and release it the same way as thelap part of a lap-shoulder belt. If the belt is not longenough, see Safety Belt Extender on page 42.

Make sure the release button on the buckle ispositioned so you would be able to unbuckle thesafety belt quickly if you ever had to.

Rear Seat PassengersIt is very important for rear seat passengers tobuckle up! Accident statistics show that unbeltedpeople in the rear seat are hurt more often incrashes than those who are wearing safety belts.

Rear passengers who are not safety beltedcan be thrown out of the vehicle in a crash. Andthey can strike others in the vehicle who arewearing safety belts.

Lap-Shoulder BeltAll rear seating positions have lap-shoulder belts.Here is how to wear one properly. 1. Pick up the latch plate and pull the belt across

you. Do not let it get twisted.The shoulder belt may lock if you pull the beltacross you very quickly. If this happens, letthe belt go back slightly to unlock it. Then pullthe belt across you more slowly.

37

Page 38: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

The lap part of the belt should be worn low andsnug on the hips, just touching the thighs. Ina crash, this applies force to the pelvic bones. Andyou would be less likely to slide under the lapbelt. If you slid under it, the belt would apply forceat your abdomen. This could cause serious oreven fatal injuries.

The shoulder belt should go over the shoulder andacross the chest. These parts of the body arebest able to take belt restraining forces.

The safety belt locks if there is a sudden stop ora crash.

{CAUTION:

You can be seriously hurt if your shoulderbelt is too loose. In a crash, you wouldmove forward too much, which couldincrease injury. The shoulder belt shouldfit against your body.

Safety Belt PretensionersYour vehicle has safety belt pretensioners for thedriver and right front passenger. Although youcannot see them, they are part of the safety beltassembly. They help tighten the safety belts duringthe early stages of a moderate to severe frontaland near frontal crash if the threshold conditionsfor pretensioner activation are met. And, ifyour vehicle has side impact airbags, safety beltpretensioners can help tighten the safety belts in aside crash.

Pretensioners work only once. If they activate in acrash, you will need to get new ones, andprobably other new parts for your safety beltsystem. See Replacing Restraint System PartsAfter a Crash on page 89.

Safety Belt ExtenderIf the vehicle’s safety belt will fasten around you,you should use it.

But if a safety belt is not long enough, your dealerwill order you an extender. When you go in toorder it, take the heaviest coat you will wear, sothe extender will be long enough for you. Tohelp avoid personal injury, do not let someone elseuse it, and use it only for the seat it is made tofit. The extender has been designed for adults.Never use it for securing child seats. To wear it,just attach it to the regular safety belt. Formore information see the instruction sheet thatcomes with the extender.

Child Restraints

Older Children

Older children who have outgrown booster seatsshould wear the vehicle’s safety belts.

Q: What is the proper way to wear safety belts?

A: An older child should wear a lap-shoulder beltand get the additional restraint a shoulder beltcan provide. The shoulder belt should notcross the face or neck. The lap belt should fitsnugly below the hips, just touching thetop of the thighs. It should never be worn overthe abdomen, which could cause severe oreven fatal internal injuries in a crash.

According to accident statistics, children are saferwhen properly restrained in the rear seatingpositions than in the front seating positions.

In a crash, children who are not buckled up canstrike other people who are buckled up, or can bethrown out of the vehicle. Older children needto use safety belts properly.

{CAUTION:

Never do this.

Here two children are wearing the samebelt. The belt can not properly spread theimpact forces. In a crash, the two childrencan be crushed together and seriouslyinjured. A belt must be used by onlyone person at a time.

Q: What if a child is wearing a lap-shoulderbelt, but the child is so small that theshoulder belt is very close to the child’sface or neck?

A: If the child is sitting in a seat next to awindow, move the child toward the center ofthe vehicle. Also see Rear Safety BeltComfort Guides on page 39. If the child issitting in the center rear seat passengerposition, move the child toward the safety beltbuckle. In either case, be sure that theshoulder belt still is on the child’s shoulder, sothat in a crash the child’s upper body wouldhave the restraint that belts provide.

{CAUTION:

Never do this.

Here a child is sitting in a seat that has alap-shoulder belt, but the shoulder part isbehind the child. If the child wears thebelt in this way, in a crash the child mightslide under the belt. The belt’s forcewould then be applied right on the child’sabdomen. That could cause serious orfatal injuries.

Wherever the child sits, the lap portion of the beltshould be worn low and snug on the hips, justtouching the child’s thighs. This applies belt forceto the child’s pelvic bones in a crash.

Infants and Young ChildrenEveryone in a vehicle needs protection! Thisincludes infants and all other children. Neither thedistance traveled nor the age and size of thetraveler changes the need, for everyone, to usesafety restraints. In fact, the law in every statein the United States and in every Canadianprovince says children up to some age must berestrained while in a vehicle.

{CAUTION:

Children can be seriously injured orstrangled if a shoulder belt is wrappedaround their neck and the safety beltcontinues to tighten. Never leave childrenunattended in a vehicle and never allowchildren to play with the safety belts.

Every time infants and young children ride invehicles, they should have the protection providedby appropriate restraints. Young children shouldnot use the vehicle’s adult safety belts alone,unless there is no other choice. Instead, they needto use a child restraint.

{CAUTION:

People should never hold a baby in theirarms while riding in a vehicle. A babydoes not weigh much — until a crash.During a crash a baby will become soheavy it is not possible to hold it. Forexample, in a crash at only 25 mph(40 km/h), a 12 lb (5.5 kg) baby willsuddenly become a 240 lb (110 kg) forceon a person’s arms. A baby should besecured in an appropriate restraint.

Q: What are the different types of add-onchild restraints?

A: Add-on child restraints, which are purchased bythe vehicle’s owner, are available in four basictypes. Selection of a particular restraint shouldtake into consideration not only the child’sweight, height, and age but also whether or notthe restraint will be compatible with the motorvehicle in which it will be used.

For most basic types of child restraints, thereare many different models available. Whenpurchasing a child restraint, be sure it isdesigned to be used in a motor vehicle. If it is,the restraint will have a label saying that itmeets federal motor vehicle safety standards.

The restraint manufacturer’s instructionsthat come with the restraint state the weightand height limitations for a particular childrestraint. In addition, there are many kindsof restraints available for children withspecial needs.

{CAUTION:

Newborn infants need complete support,including support for the head and neck.This is necessary because a newborninfant’s neck is weak and its head weighsso much compared with the rest of itsbody. In a crash, an infant in a rear-facingseat settles into the restraint, so the crashforces can be distributed across thestrongest part of an infant’s body, theback and shoulders. Infants alwaysshould be secured in appropriate infantrestraints.

48

Page 49: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

{CAUTION:

The body structure of a young child isquite unlike that of an adult or older child,for whom the safety belts are designed. Ayoung child’s hip bones are still so smallthat the vehicle’s regular safety belt maynot remain low on the hip bones, as itshould. Instead, it may settle up aroundthe child’s abdomen. In a crash, the beltwould apply force on a body area that isunprotected by any bony structure. Thisalone could cause serious or fatal injuries.Young children always should be securedin appropriate child restraints.

Child Restraint Systems

An infant car bed (A), a special bed made for usein a motor vehicle, is an infant restraint systemdesigned to restrain or position a child on acontinuous flat surface. Make sure that the infant’shead rests toward the center of the vehicle.

A rear-facing infant seat (B) provides restraint withthe seating surface against the back of theinfant. The harness system holds the infant inplace and, in a crash, acts to keep the infantpositioned in the restraint.

A forward-facing child seat (C-E) provides restraintfor the child’s body with the harness and alsosometimes with surfaces such as T-shapedor shelf-like shields.

50

A booster seat (F-G) is a child restraint designedto improve the fit of the vehicle’s safety beltsystem. Some booster seats have a shoulder beltpositioner, and some high-back booster seatshave a five-point harness. A booster seat can alsohelp a child to see out the window.

Q: How Should I Use a Child Restraint?

A: A child restraint system is any device designedfor use in a motor vehicle to restrain, seat, orposition children. A built-in child restraintsystem is a permanent part of the motorvehicle. An add-on child restraint system is aportable one, which is purchased by thevehicle’s owner. To help reduce injuries, anadd-on child restraint must be secured inthe vehicle. With built-in or add-on childrestraints, the child has to be secured withinthe child restraint.

When choosing an add-on child restraint, besure the child restraint is designed to beused in a vehicle. If it is, it will have a labelsaying that it meets federal motor vehiclesafety standards. Then follow the instructionsfor the restraint. You may find theseinstructions on the restraint itself or in abooklet, or both.

Securing an Add-on Child Restraint inthe Vehicle

{CAUTION:

A child can be seriously injured or killed ina crash if the child restraint is not properlysecured in the vehicle. Make sure the childrestraint is properly installed in the vehicleusing the vehicle’s safety belt or LATCHsystem, following the instructions thatcame with that restraint, and also theinstructions in this manual.

To help reduce the chance of injury, the childrestraint must be secured in the vehicle. Childrestraint systems must be secured in vehicle seatsby lap belts or the lap belt portion of a lap-shoulderbelt, or by the LATCH system.

See Lower Anchors and Tethers for Children(LATCH) on page 55 for more information. A childcan be endangered in a crash if the childrestraint is not properly secured in the vehicle.

When securing an add-on child restraint, refer tothe instructions that come with the restraintwhich may be on the restraint itself or in a booklet,or both, and to this manual. The child restraintinstructions are important, so if they are notavailable, obtain a replacement copy from themanufacturer.

Keep in mind that an unsecured child restraint canmove around in a collision or sudden stop andinjure people in the vehicle. Be sure to properlysecure any child restraint in your vehicle — evenwhen no child is in it.

Securing the Child Within the ChildRestraintThere are several systems for securing the childwithin the child restraint. One system, thethree-point harness, has straps that come downover each of the infant’s shoulders and buckletogether at the crotch. The five-point harnesssystem has two shoulder straps, two hip straps, anda crotch strap. A shield may take the place of hipstraps. A T-shaped shield has shoulder straps thatare attached to a flat pad which rests low againstthe child’s body. A shelf- or armrest-type shield hasstraps that are attached to a wide, shelf-like shieldthat swings up or to the side.

{CAUTION:

A child can be seriously injured or killedin a crash if the child is not properlysecured in the child restraint. Make surethe child is properly secured, followingthe instructions that came with thatrestraint.

Because there are different systems, it is importantto refer to the instructions that come with therestraint. A child can be endangered in a crash ifthe child is not properly secured in the childrestraint.

Where to Put the RestraintAccident statistics show that children are safer ifthey are restrained in the rear rather than the frontseat. We, therefore, recommend that childrestraints be secured in a rear seat, including aninfant riding in a rear-facing infant seat, a childriding in a forward-facing child seat and an olderchild riding in a booster seat.

53

Your vehicle has a rear seat that will accommodatea rear-facing child restraint. A label on your sunvisor says, “Never put a rear-facing child seatin the front.” This is because the risk to therear-facing child is so great, if the airbag deploys.

{CAUTION:

A child in a rear-facing child restraint canbe seriously injured or killed if the rightfront passenger’s airbag inflates. This isbecause the back of the rear-facing childrestraint would be very close to theinflating airbag.Even though the passenger sensingsystem is designed to turn off the rightfront passenger’s frontal and seat-mountedside impact airbag if the system detects arear-facing child restraint, no system is

CAUTION: (Continued)

CAUTION: (Continued)

fail-safe, and no one can guarantee thatan airbag will not deploy under someunusual circumstance, even though it isturned off. We recommend that rear-facingchild restraints be secured in the rearseat, even if the airbags are off.If you need to secure a forward-facingchild restraint in the right front seat,always move the front passenger seat asfar back as it will go. It is better to securethe child restraint in a rear seat.

{CAUTION:

A child in a child restraint in the centerfront seat can be badly injured or killed bythe right front passenger’s airbag if itinflates. Never secure a child restraint inthe center front seat. It is always better tosecure a child restraint in the rear seat.

Keep in mind that an unsecured child restraint canmove around in a collision or sudden stop andinjure people in the vehicle. Be sure to properlysecure any child restraint in your vehicle — evenwhen no child is in it.

Lower Anchors and Tethers forChildren (LATCH)The LATCH system holds a child restraint duringdriving or in a crash. This system is designedto make installation of a child restraint easier. TheLATCH system uses anchors in the vehicle andattachments on the child restraint that are made foruse with the LATCH system

Make sure that a LATCH-compatible child restraintis properly installed using the anchors, or usethe vehicle’s safety belts to secure the restraint,following the instructions that came with thatrestraint, and also the instructions in this manual.

When installing a child restraint with a top tether,you must also use either the lower anchors orthe safety belts to properly secure the childrestraint. A child restraint must never be installedusing only the top tether and anchor.

In order to use the LATCH system in your vehicle,you need a child restraint that has LATCHattachments. The child restraint manufacturer willprovide you with instructions on how to usethe child restraint and its attachments. Thefollowing explains how to attach a child restraintwith these attachments in your vehicle.

Not all vehicle seating positions or child restraintshave lower anchors and attachments or toptether anchors and attachments.

Lower Anchors

Lower anchors (A) are metal bars built into thevehicle. There are two lower anchors for eachLATCH seating position that will accommodate achild restraint with lower attachments (B).

Top Tether Anchor

A top tether (A, C) anchors the top of the childrestraint to the vehicle. A top tether anchor is builtinto the vehicle. The top tether attachment (B)on the child restraint connects to the top tetheranchor in the vehicle in order to reduce the forwardmovement and rotation of the child restraintduring driving or in a crash.

Your child restraint may have a single tether (A) ora dual tether (C). Either will have a singleattachment (B) to secure the top tether to theanchor.

Some child restraints that have a top tether aredesigned for use with or without the top tetherbeing attached. Others require the top tetheralways to be attached. In Canada, the law requiresthat forward-facing child restraints have a toptether, and that the tether be attached. Inthe United States, some child restraints also havea top tether. Be sure to read and follow theinstructions for your child restraint.

If the child restraint does not have a top tether,one can be obtained, in kit form, for manychild restraints. Ask the child restraintmanufacturer whether or not a kit is available.

Securing a Child Restraint in theCenter Front Seat Position

{CAUTION:

A child in a child restraint in the centerfront seat can be badly injured or killed bythe right front passenger’s airbag if itinflates. Never secure a child restraint inthe center front seat. It is always better tosecure a child restraint in the rear seat.

Do not secure a child restraint in the center frontseat position.

Securing a Child Restraint in theRight Front Seat PositionYour vehicle has a right front passenger’s airbag.A rear seat is a safer place to secure aforward-facing child restraint. See Where to Putthe Restraint on page 53.

In addition, your vehicle has a passenger sensingsystem. The passenger sensing system isdesigned to turn off the right front passenger’sfrontal airbag and seat-mounted side impact airbagwhen an infant in a rear-facing infant seat or asmall child in a forward-facing child restraintor booster seat is detected. See PassengerSensing System on page 81 and Passenger AirbagStatus Indicator on page 198 for more informationon this, including important safety information.

Airbag SystemYour vehicle has six airbags:

• A frontal airbag for the driver and anotherfrontal airbag for the right front passenger.

• A seat-mounted side impact airbag for thedriver and another for the right frontpassenger.

• A roof-mounted side impact airbag for thedriver and passenger directly behind the driver.

• A roof-mounted side impact airbag for the rightfront passenger and the person seated directlybehind that passenger.

Airbags are designed to supplement the protectionprovided by safety belts. Even though today’sairbags are also designed to help reduce the riskof injury from the force of an inflating bag, allairbags must inflate very quickly to do their job.

Here are the most important things to know aboutthe airbag system:

{CAUTION:

You can be severely injured or killed in acrash if you are not wearing your safetybelt — even if you have airbags. Wearingyour safety belt during a crash helpsreduce your chance of hitting thingsinside the vehicle or being ejected from it.Airbags are “supplemental restraints” tothe safety belts. All airbags are designedto work with safety belts but do notreplace them.

CAUTION: (Continued)

CAUTION: (Continued)

Frontal airbags for the driver and rightfront passenger are designed to deploy inmoderate to severe frontal and nearfrontal crashes. They are not designed toinflate in rollover, rear crashes, or in manyside crashes. And, for some unrestrainedoccupants, frontal airbags may provideless protection in frontal crashes thanmore forceful airbags have provided inthe past.

Seat-mounted side impact airbags androof-mounted side impact airbags aredesigned to inflate in moderate to severecrashes where something hits the side ofyour vehicle. They are not designed toinflate in frontal, in rollover or in rearcrashes. Everyone in your vehicle shouldwear a safety belt properly — whether ornot there is an airbag for that person.

{CAUTION:

Both frontal and side impact airbagsinflate with great force, faster than theblink of an eye. If you are too close to aninflating airbag, as you would be if youwere leaning forward, it could seriouslyinjure you. Safety belts help keep you inposition for airbag inflation before andduring a crash. Always wear your safetybelt even with frontal airbags. The drivershould sit as far back as possible whilestill maintaining control of the vehicle.Occupants should not lean on or sleepagainst the door.

{CAUTION:

Anyone who is up against, or very close to,any airbag when it inflates can be seriouslyinjured or killed. Airbags plus lap-shoulderbelts offer the best protection for adults,but not for young children and infants.Neither the vehicle’s safety belt system norits airbag system is designed for them.Young children and infants need theprotection that a child restraint system canprovide. Always secure children properlyin your vehicle. To read how, see OlderChildren on page 43 or Infants and YoungChildren on page 46.

There is an airbagreadiness light on theinstrument panel cluster,which shows theairbag symbol.

The system checks the airbag electrical system formalfunctions. The light tells you if there is anelectrical problem. See Airbag Readiness Light onpage 197 for more information.

Where Are the Airbags?

The driver’s frontal airbag is in the middle of thesteering wheel.

{CAUTION:

If something is between an occupant andan airbag, the airbag might not inflateproperly or it might force the object intothat person causing severe injury or evendeath. The path of an inflating airbag mustbe kept clear. Do not put anythingbetween an occupant and an airbag, anddo not attach or put anything on thesteering wheel hub or on or near anyother airbag covering. Never secureanything to the roof of your vehicle byrouting the rope or tie-down through anydoor or window opening. If you do, thepath of an inflating airbag will be blocked.Do not let seat covers block the inflationpath of a side impact airbag. The path ofan inflating airbag must be kept clear.

When Should an Airbag Inflate?The driver’s and right front passenger’s frontalairbags are designed to inflate in moderate tosevere frontal or near-frontal crashes. But they aredesigned to inflate only if the impact exceeds apredetermined deployment threshold. Deploymentthresholds take into account a variety of desireddeployment and non-deployment events and areused to predict how severe a crash is likely to be intime for the airbags to inflate and help restrain theoccupants. Whether your frontal airbags will orshould deploy is not based on how fast your vehicleis traveling. It depends largely on what you hit, thedirection of the impact, and how quickly yourvehicle slows down.

Your vehicle has a “dual stage” driver airbag,which adjusts the restraint according to crashseverity using electronic frontal sensor(s) whichhelp the sensing system distinguish betweena moderate frontal impact and a more severefrontal impact. The “dual stage” driver airbaginflates to a level less than full deployment formoderate frontal impacts and to a full deploymentfor more severe frontal impacts.

Your vehicle also has a “dual depth” passengerairbag that adjusts the restraint according to crashseverity, seat location, and safety belt statususing electronic frontal sensor(s) and other specialsensors which enable the sensing system tomonitor the status of the front passenger safetybelt and the position of the front passengerseat. The passenger airbag inflates to a reduceddepth when the passenger seat is in a forwardposition. For more rearward front seating positions,the passenger airbag may inflate to an increaseddepth (a full deployment), based on safetybelt status and the crash severity measured earlyin the event. (Always wear your safety belt,even with frontal airbags.)

76

Page 77: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

If the front of your vehicle goes straight into a wallthat does not move or deform, the thresholdlevel for the reduced deployment is about12 to 16 mph (19 to 26 km/h), and the thresholdlevel for a full deployment is about 17 to 22 mph(27 to 35 km/h) if the other sensors do notover-ride this. The threshold level can vary,however, with specific vehicle design, so that itcan be somewhat above or below this range.

Frontal airbags may inflate at different crashspeeds. For example:

• If the vehicle hits a stationary object, theairbags could inflate at a different crash speedthan if the vehicle hits a moving object.

• If the vehicle hits an object that deforms, theairbags could inflate at a different crashspeed than if the vehicle hits an object thatdoes not deform.

• If the vehicle hits a narrow object (like a pole),the airbags could inflate at a different crashspeed than if the vehicle hits a wide object(like a wall).

• If the vehicle goes into an object at an angle,the airbags could inflate at a different crashspeed than if the vehicle goes straight into theobject.

Frontal airbags (driver and right front passenger)are not intended to inflate during vehiclerollovers, rear impacts, or in many side impacts.

Your vehicle has sensors which enable thesensing system to monitor the position of the rightfront passenger’s seat, whether the occupant isbuckled or unbuckled. The passenger seat positionsensor and passenger safety belt buckle switchprovide information which is used to determine ifthe airbags should deploy at a reduced level or fulldeployment.

77

Page 78: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Side impact airbags are intended to inflate inmoderate to severe side crashes. A side impactairbag will inflate if the crash severity is above thesystem’s designed “threshold level.” Thethreshold level can vary with specific vehicledesign. Side impact airbags are not intended toinflate in frontal or near-frontal impacts, rollovers,or rear impacts. Both roof-mounted side impactairbags will deploy when either side of the vehicleis struck.

In any particular crash, no one can say whetheran airbag should have inflated simply becauseof the damage to a vehicle or because of what therepair costs were. For frontal airbags, inflation isdetermined by what the vehicle hits, the angleof the impact, and how quickly the vehicle slowsdown. For side impact airbags, inflation isdetermined by the location and severity of theimpact.

What Makes an Airbag Inflate?In an impact of sufficient severity, the airbagsensing system detects that the vehicle isin a crash. The sensing system triggers a releaseof gas from the inflator, which inflates theairbag. The inflator, airbag and related hardwareare all part of the airbag modules. Frontalairbag modules are located inside the steeringwheel and the instrument panel. For vehicles withseat-mounted side impact airbags, there arealso airbag modules in the side of the frontseatbacks closest to the door. For vehicles withroof-mounted side impact airbags, there arealso airbag modules in the ceiling of the vehicle,near the side window.

78

Page 79: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

How Does an Airbag Restrain?In moderate to severe frontal or near frontalcollisions, even belted occupants can contact thesteering wheel or the instrument panel. Inmoderate to severe side collisions, even beltedoccupants can contact the inside of the vehicle.Airbags supplement the protection providedby safety belts. Airbags distribute the force of theimpact more evenly over the occupant’s upperbody, stopping the occupant more gradually. Butthe frontal airbags would not help you in manytypes of collisions, including rollovers, rearimpacts, and many side impacts, primarily becausean occupant’s motion is not toward the airbag.Side impact airbags would not help you in manytypes of collisions, including many frontal ornear frontal collisions, rollovers, and rear impacts.

Airbags should never be regarded as anythingmore than a supplement to safety belts, and thenonly in moderate to severe frontal or near-frontalcollisions for the driver’s and right frontpassenger’s frontal airbags, and only in moderateto severe side collisions for vehicles with sideimpact airbags.

What Will You See After an AirbagInflates?After frontal airbags and seat-mounted side impactairbags inflate, they quickly deflate, so quicklythat some people may not even realize an airbaginflated. Roof-mounted side impact airbagsmay still be at least partially inflated minutes afterthe vehicle comes to rest. Some componentsof the airbag module — the steering wheel hub forthe driver’s airbag, the instrument panel for theright front passenger’s bag, the side of theseatback closest to the door for the seat-mountedside impact airbags, and the area along theceiling of your vehicle near the side windows forroof-mounted side impact airbags — may behot for a short time. The parts of the airbag thatcome into contact with you may be warm, but nottoo hot to touch.

There may be some smoke and dust coming fromthe vents in the deflated airbags. Airbag inflationdoes not prevent the driver from seeing out of thewindshield or being able to steer the vehicle,nor does it prevent people from leaving the vehicle.

{CAUTION:

When an airbag inflates, there may bedust in the air. This dust could causebreathing problems for people with ahistory of asthma or other breathingtrouble. To avoid this, everyone in thevehicle should get out as soon as it issafe to do so. If you have breathingproblems but cannot get out of the vehicleafter an airbag inflates, then get fresh airby opening a window or a door. If youexperience breathing problems followingan airbag deployment, you should seekmedical attention.

Your vehicle has a feature that may automaticallyunlock the doors, turn the interior lamps on, andturn the hazard warning flashers on when theairbags inflate. You can lock the doors, turn theinterior lamps off, and turn the hazard warningflashers off by using the controls for those features.

In many crashes severe enough to inflate theairbag, windshields are broken by vehicledeformation. Additional windshield breakage mayalso occur from the right front passengerairbag.

• Airbags are designed to inflate only once.After an airbag inflates, you will needsome new parts for the airbag system. If youdo not get them, the airbag system willnot be there to help protect you in anothercrash. A new system will include airbagmodules and possibly other parts. The servicemanual for your vehicle covers the need toreplace other parts.

• Your vehicle has a crash sensing anddiagnostic module which records informationafter a crash. See Vehicle Data Collection andEvent Data Recorders on page 471.

Passenger Sensing SystemYour vehicle has a passenger sensing system.The passenger airbag status indicator on theoverhead console will be visible when you turnyour ignition key to RUN or START.

The words ON and OFF or the symbol for on andoff, will be visible during the system check.When the system check is complete, either theword ON or the word OFF, or the symbol for on orthe symbol for off will be visible. See PassengerAirbag Status Indicator on page 198.

The passenger sensing system will turn off theright front passenger’s frontal airbag andseat-mounted side impact airbag under certainconditions. The driver’s airbags are not part of thepassenger sensing system.

The passenger sensing system works with sensorsthat are part of the right front passenger’s seat andsafety belt. The sensors are designed to detect thepresence of a properly-seated occupant anddetermine if the right front passenger’s frontalairbag and seat-mounted side impact airbag shouldbe enabled (may inflate) or not.

Accident statistics show that children are safer ifthey are restrained in the rear rather than the frontseat. We recommend that child restraints besecured in a rear seat, including an infant riding ina rear-facing infant seat, a child riding in aforward-facing child seat and an older child ridingin a booster seat.United States Canada

To help makesure your restraint systems are workingproperly after a crash, have them inspectedand any necessary replacements made assoon as possible.

If you have had a crash, do you need new belts orLATCH system parts?After a very minor collision, nothing may benecessary. But if the belts were stretched, as theywould be if worn during a more severe crash,then you need new parts.If the LATCH system was being used during amore severe crash, you may need new LATCHsystem parts.

If belts are cut or damaged, replace them.Collision damage also may mean you will need tohave LATCH system, safety belt or seat partsrepaired or replaced. New parts and repairs maybe necessary even if the belt or LATCH systemwas not being used at the time of the collision.

If an airbag inflates, you will need to replace airbagsystem parts. See the part on the airbag systemearlier in this section.

If the frontal airbags inflate you will also need toreplace the driver and front passenger’s safety beltretractor assembly. Be sure to do so. Then thenew retractor assembly will be there to help protectyou in a collision.

After a crash you may need to replace the driverand front passenger’s safety belt retractorassemblies, even if the frontal airbags have notdeployed. The driver and front passenger’s safetybelt retractor assemblies contain the safety beltpretensioners. Have your safety belt pretensionerschecked if your vehicle has been in a collision,or if your airbag readiness light stays on after youstart your vehicle or while you are driving. SeeAirbag Readiness Light on page 197.

When trying to start the vehicle if the engine doesnot start and the security light on the instrumentpanel cluster comes on, the key may have adamaged transponder. Turn the ignition off andtry again.

If the engine still does not start, and the keyappears to be not damaged, try another ignitionkey. At this time, you may also want to check thefuse, see Fuses and Circuit Breakers on page 428.If the engine still does not start with the other key,your vehicle needs service. If your vehicle doesstart, the first key may be faulty. See your dealerwho can service the PASS-Key® III+ to have a newkey made. In an emergency, contact RoadsideAssistance. See Roadside Assistance Programon page 466.

It is possible for the PASS-Key® III+ decoderto “learn” the transponder value of a new orreplacement key. Up to 10 keys may beprogrammed for the vehicle. The followingprocedure is for programming additional keysonly. If all the currently programmed keys are lostor do not operate, you must see your dealer or alocksmith who can service PASS-Key® III+ to havekeys made and programmed to the system.

See your dealer or a locksmith who can servicePASS-Key® III+ to get a new key blank that is cutexactly as the ignition key that operates the system.

Starting and Operating YourVehicle

New Vehicle Break-In

Notice: Your vehicle does not need anelaborate break-in. But it will perform better inthe long run if you follow these guidelines:• Do not drive at any one constant speed, fast

or slow, for the first 500 miles (805 km).Do not make full-throttle starts. Avoiddownshifting to brake, or slow, the vehicle.

• Avoid making hard stops for the first200 miles (322 km) or so. During this timeyour new brake linings are not yet brokenin. Hard stops with new linings can meanpremature wear and earlier replacement.Follow this breaking-in guideline everytime you get new brake linings.

• Do not tow a trailer during break-in. SeeTowing a Trailer on page 315 for the trailertowing capabilities of your vehicle and moreinformation.

Following break-in, engine speed and load canbe gradually increased.

Starting the EnginePlace the transaxle in the proper gear.

Move your shift lever to PARK (P) orNEUTRAL (N). Your engine will not start inany other position — this is a safety feature.To restart when you are already moving,use NEUTRAL (N) only.

Notice: Shifting into PARK (P) with the vehiclemoving could damage the transaxle. Shiftinto PARK (P) only when your vehicle isstopped.

Starting Procedure1. With your foot off the accelerator pedal, turn

the ignition key to START. When the enginestarts, let go of the key. The idle speed willgo down as your engine gets warm. Donot race the engine immediately after startingit. Operate the engine and transaxle gentlyto allow the oil to warm up and lubricateall moving parts.

Your vehicle has a Computer-ControlledCranking System. This feature assists instarting the engine and protects components. Ifthe ignition key is turned to the START position,and then released when the engine beginscranking, the engine will continue cranking fora few seconds or until the vehicle starts. If theengine does not start and the key is held inSTART for many seconds, cranking will bestopped after 15 seconds to prevent crankingmotor damage. To prevent gear damage, thissystem also prevents cranking if the engine isalready running. Engine cranking can bestopped by turning the ignition switch tothe ACCESSORY or OFF position.

Notice: Cranking the engine for long periodsof time, by returning the key to the STARTposition immediately after cranking has ended,can overheat and damage the crankingmotor, and drain the battery. Wait at least15 seconds between each try, to allowthe cranking motor to cool down.

2. If the engine does not start after 5-10 seconds,especially in very cold weather (below 0°For −18°C), it could be flooded with too muchgasoline. Try pushing the accelerator pedal allthe way to the floor and holding it there as youhold the key in START for up to a maximum of15 seconds. Wait at least 15 seconds betweeneach try, to allow the cranking motor to cooldown. When the engine starts, let go of the keyand accelerator. If the vehicle starts briefly butthen stops again, do the same thing. Thisclears the extra gasoline from the engine. Donot race the engine immediately after startingit. Operate the engine and transaxle gentlyuntil the oil warms up and lubricates allmoving parts.

Notice: Your engine is designed to work withthe electronics in your vehicle. If you addelectrical parts or accessories, you couldchange the way the engine operates. Beforeadding electrical equipment, check withyour dealer. If you do not, your engine mightnot perform properly. Any resulting damagewould not be covered by your vehicle’swarranty.

Engine Coolant HeaterIf your vehicle has this feature, in very cold weather,0°F (−18°C) or colder, the engine coolant heatercan help. You’ll get easier starting and better fueleconomy during engine warm-up. Usually, thecoolant heater should be plugged in a minimumof four hours prior to starting your vehicle.At temperatures above 32°F (0°C), use of thecoolant heater is not required.

Page 118: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

To Use the Engine Coolant Heater1. Turn off the engine.

2. Open the hood and unwrap the electrical cord.On vehicles with the 3.8L V6 engine,the coolant heater cord is located on thepassenger’s side of the vehicle, above theheadlamp assembly. On vehicles with the 4.6LV8 engine, the cord is located on the driver’sside of the vehicle on the right side of theengine air cleaner. It is between the enginecover and the engine air cleaner.

{CAUTION:

Plugging the cord into an ungroundedoutlet could cause an electrical shock.Also, the wrong kind of extension cordcould overheat and cause a fire. Youcould be seriously injured. Plug the cordinto a properly grounded three-prong110-volt AC outlet. If the cord will notreach, use a heavy-duty three-prongextension cord rated for at least 15 amps.

3. Plug the cord into a normal, grounded110-volt AC outlet.

4. Before starting the engine, be sure to unplugand store the cord as it was before to keep itaway from moving engine parts. If you donot, it could be damaged.

How long should you keep the coolant heaterplugged in? The answer depends on the outsidetemperature, the kind of oil you have, and someother things. Instead of trying to list everything here,we ask that you contact your dealer in the areawhere you will be parking your vehicle. The dealercan give you the best advice for that particular area.

• Going about 35 mph (55 km/h) or more, pushthe accelerator all the way down.You will shift down to the next gear and havemore power.

Downshifting the transaxle in slippery roadconditions could result in skidding, see “Skidding”under Loss of Control on page 290.

THIRD (3): This position is also used for normaldriving. It reduces vehicle speed more thanDRIVE (D) without using your brakes. You mightchoose THIRD (3) instead of DRIVE (D) whendriving on hilly, winding roads, when towinga trailer, so there is less shifting between gearsand when going down a steep hill.

SECOND (2): This position reduces vehicle speedeven more than THIRD (3) without using yourbrakes. You can use SECOND (2) on hills. It canhelp control your speed as you go down steepmountain roads, but then you would also want touse your brakes off and on.

Notice: Driving in SECOND (2) for more than25 miles (40 km) or at speeds over 55 mph(90 km/h) may damage the transaxle. Also,shifting into SECOND (2) at speeds above65 mph (105 km/h) can cause damage. Drive inTHIRD (3) or DRIVE (D) instead of SECOND (2).

FIRST (1): This position reduces vehicle speedeven more than SECOND (2) without using yourbrakes. You can use it on very steep hills, or indeep snow or mud. If the shift lever is put inFIRST (1) while going forward, the transaxle willnot shift into first gear until the vehicle is goingslowly enough.

Notice: Spinning the tires or holding thevehicle in one place on a hill using only theaccelerator pedal may damage the transaxle.If you are stuck, do not spin the tires. Whenstopping on a hill, use the brakes, or parkingbrake to hold the vehicle in place.

Rainsense™ II WipersIf your vehicle has this feature, the moisture sensoris mounted on the interior of the windshield besidethe rearview mirror and is used to automaticallyoperate the wipers. This system operates bymonitoring the amount of moisture build-up on thewindshield. Wipes occur as needed to clear thewindshield depending on the driving conditions andthe sensitivity setting. In light rain or snow, fewerwipes will occur. In heavy rain or snow, wipes willoccur more frequently. The system operates in thedelay mode. If the system is left on for long periodsof time, occasional wipes may occur without anymoisture on the windshield. This is normal andindicates that the Rainsense™ system is active.

The Rainsense™ system is activated by turningthe wiper control band to one of the five sensitivitylevels within the delay area. The position closestto off is the lowest sensitivity setting, level one.

This allows more rain or snow to collect on thewindshield between wipes. Turning the wiper bandaway from you to higher sensitivity levels increasesthe sensitivity of the system and frequency ofwipes. The highest sensitivity setting, level five isclosest to low. A single wipe will occur each timeyou turn the wiper stalk to a higher sensitivity levelto indicate that the sensitivity level has beenincreased.

Notice: Going through an automatic car washwith the wipers on can damage them. Turn thewipers off when going through an automaticcar wash.

The MIST and wash cycles operate as normal andare not affected by the Rainsense™ function. Thesystem can be overridden at any time by manuallychanging the wiper control to low or high speed.

Notice: Do not place stickers or other itemson the exterior glass surface directly in front ofthe rain sensor. Doing this could cause therain sensor to malfunction.

Electric Power ManagementThe vehicle has Electric Power Management(EPM) that estimates the battery’s temperature andstate of charge. It then adjusts the voltage forbest performance and extended life of the battery.

When the battery’s state of charge is low, thevoltage is raised slightly to quickly put the chargeback in. When the state of charge is high, thevoltage is lowered slightly to prevent overcharging.If the vehicle has a voltmeter gage or voltagedisplay on the Driver Information Center (DIC),you may see the voltage move up or down. Thisis normal. If there is a problem, an alert willbe displayed.

The battery can be discharged at idle if theelectrical loads are very high. This is true for allvehicles. This is because the generator (alternator)may not be spinning fast enough at idle to produceall the power that is needed for very high electricalloads.

A high electrical load occurs when several of thefollowing loads are on: headlamps, high beams, foglamps, rear window defogger, climate control fan athigh speed, heated seats, engine cooling fans,trailer loads, and loads plugged into accessorypower outlets.

EPM works to prevent excessive discharge of thebattery. It does this by balancing the generator’soutput and the vehicle’s electrical needs. It canincrease engine idle speed to generate morepower, whenever needed. It can temporarilyreduce the power demands of some accessories.

Normally, these actions occur in steps or levels,without being noticeable. In rare cases at thehighest levels of corrective action, this actionmay be noticeable to the driver. If so, a DriverInformation Center (DIC) message might bedisplayed, such as Battery Saver Active or ServiceBattery Charging System. If this message isdisplayed, it is recommended that the driverreduce the electrical loads as much as possible.See DIC Warnings and Messages on page 221.

Ultrasonic Rear ParkingAssist (URPA)If your vehicle is equipped, the Ultrasonic RearParking Assist (URPA) system is designed to helpyou park while in REVERSE (R). It operates only atspeeds less than 5 mph (8 km/h). URPA helpsmake parking easier and helps you avoid collidingwith objects such as parked vehicles. The URPAsystem detects objects that are close to the rear ofthe vehicle which are at least 10 inches (25.4 cm)off the ground and below hood or trunk level. Thesystem detects objects up to 8 feet (2.5 m) behindyour vehicle. URPA determines how close theseobjects are from your bumper within this area.Ultrasonic sensors on the rear bumper are usedto detect the distance to the object.

{CAUTION:

The Ultrasonic Rear Park Assist (URPA)system does not replace driver vision.URPA does not:

• Operate above speeds of5 mph (8 km/h).

• Detect objects more than 8 feet(2.5 meters) behind the vehicle. Thisdistance may be less during warmer orhumid weather.

• Detect objects that are below thebumper, underneath the vehicle,or that are very close to the vehicle.

• Detect children, pedestrians, bicyclists,or pets.

So if you do not use proper care beforebacking up, you could hit a vehicle, child,pedestrian, bicyclist, or pet, resulting invehicle damage, injury, or death. Eventhough the vehicle has the URPA system,always check carefully before backing upby checking behind your vehicle.

When the System Does Not Seem toWork ProperlyIf the URPA system will not activate due to atemporary condition, the message PARK ASSISTOFF will be displayed on the DIC and a red light willbe shown on the rear URPA display when the shiftlever is moved into REVERSE (R). This occursunder the following conditions:

• The driver disables the system. See DICControls and Displays on page 212.

• The parking brake pedal is pressed.

• A trailer was attached to your vehicle, or abicycle or an object was hanging out of yourtrunk during your last drive when you turned offthe vehicle. If the attached objects are removedfrom your vehicle before the start of your nextdrive, the system will return to normal operationunless an object is detected when the vehicle isshifted into REVERSE (R). If this occurs, URPAassumes the object is still attached, so you willhave to wait until the vehicle is driven forwardabove 15 mph (25 km/h) before URPA willreturn to normal operation.

• The ultrasonic sensors are not kept clean. So,be sure to keep your vehicle’s rear bumper freeof mud, dirt, snow, ice, and slush. For cleaninginstructions, see Washing Your Vehicle onpage 422. If the DIC still displays the PARKASSIST OFF message after cleaning thebumper and driving forward at a speed of atleast 15 mph (25 km/h), see your dealer.

• Other conditions that may affect systemperformance include vibrations from ajackhammer or the compression of air brakeson a very large truck or other mechanicaldevices that interfere with URPA performance.

• When URPA is disabled without driver actionand the driver attempts to turn URPA back onusing the Driver Information Center (DIC), thePARK ASSIST ON option will not be selectableif the necessary conditions stated above fornormal system operation are not met.

As always, drivers should use care when backingup a vehicle. Always look behind you, being sure tocheck for other vehicles, obstructions and blindspots.

{CAUTION:

If the on indicator comes on when you havea rear-facing child restraint installed in theright front passenger’s seat, it means thatthe passenger sensing system has notturned off the passenger’s frontal airbagand seat-mounted side impact airbag.A child in a rear-facing child restraint canbe seriously injured or killed if the rightfront passenger’s airbag inflates. This isbecause the back of the rear-facing childrestraint would be very close to theinflating airbag. Do not use a rear-facingchild restraint in the right front passenger’sseat if the airbag is turned on.

Your vehicle has a rear seat that will accommodatea rear-facing child restraint. A label on your sunvisor says, “Never put a rear-facing child seatin the front.” This is because the risk to therear-facing child is so great, if the airbag deploys.

{CAUTION:

Even though the passenger sensingsystem is designed to turn off thepassenger’s frontal airbag andseat-mounted side impact airbag if thesystem detects a rear-facing child restraint,no system is fail-safe, and no one canguarantee that an airbag will not deployunder some unusual circumstance, eventhough it is turned off. We recommend thatrear-facing child restraints be secured inthe rear seat, even if the airbag is off.

If the word OFF or the off symbol is lit on theairbag status indicator, it means that the passengersensing system has turned off the right frontpassenger’s frontal airbag and seat-mounted sideimpact airbag.

Malfunction Indicator Lamp

Check Engine Light

Your vehicle has acomputer whichmonitors operationof the fuel, ignition,and emission controlsystems.

This system is called OBD II (On-BoardDiagnostics-Second Generation) and is intended toassure that emissions are at acceptable levels forthe life of the vehicle, helping to produce a cleanerenvironment. The check engine light comes on toindicate that there is a problem and service isrequired. Malfunctions often will be indicated bythe system before any problem is apparent. Thismay prevent more serious damage to your vehicle.This system is also designed to assist your servicetechnician in correctly diagnosing any malfunction.

Notice: If you keep driving your vehicle withthis light on, after awhile, your emissioncontrols may not work as well, your fueleconomy may not be as good, and your enginemay not run as smoothly. This could lead tocostly repairs that may not be covered by yourwarranty.

Notice: Modifications made to the engine,transaxle, exhaust, intake, or fuel system ofyour vehicle or the replacement of the originaltires with other than those of the same TirePerformance Criteria (TPC) can affect yourvehicle’s emission controls and may causethis light to come on. Modifications to thesesystems could lead to costly repairs notcovered by your warranty. This may alsoresult in a failure to pass a required EmissionInspection/Maintenance test. See Accessoriesand Modifications on page 325.

This light should come on, as a check to show you itis working, when the ignition is on and the engine isnot running. If the light does not come on, have itrepaired. This light will also come on during amalfunction in one of two ways:

• Light Flashing — A misfire condition has beendetected. A misfire increases vehicle emissionsand may damage the emission control systemon your vehicle. Diagnosisand service may be required.

• Light On Steady — An emission controlsystem malfunction has been detected onyour vehicle. Diagnosis and service may berequired.

If the Light Is FlashingThe following may prevent more serious damageto your vehicle:

• Reducing vehicle speed

• Avoiding hard accelerations

• Avoiding steep uphill grades

• If you are towing a trailer, reduce the amount ofcargo being hauled as soon as it is possible

If the light stops flashing and remains on steady,see “If the Light Is On Steady” following.

If the light continues to flash, when it is safe to doso, stop the vehicle. Find a safe place to parkyour vehicle. Turn the key off, wait at least10 seconds and restart the engine. If the lightremains on steady, see “If the Light Is On Steady”following. If the light is still flashing, follow theprevious steps, and see your dealer for serviceas soon as possible.

If the Light Is On SteadyYou may be able to correct the emission systemmalfunction by considering the following:

Did you recently put fuel into your vehicle?

If so, reinstall the fuel cap, making sure to fullyinstall the cap. See Filling the Tank on page 330.The diagnostic system can determine if the fuel caphas been left off or improperly installed. A loose ormissing fuel cap will allow fuel to evaporate into theatmosphere. A few driving trips with the capproperly installed should turn the light off.

Did you just drive through a deep puddle ofwater?If so, your electrical system may be wet. Thecondition will usually be corrected when theelectrical system dries out. A few driving tripsshould turn the light off.Have you recently changed brands of fuel?If so, be sure to fuel your vehicle with quality fuel.See Gasoline Octane on page 327. Poor fuelquality will cause your engine not to run asefficiently as designed. You may notice this asstalling after start-up, stalling when you putthe vehicle into gear, misfiring, hesitation onacceleration, or stumbling on acceleration. (Theseconditions may go away once the engine is warmedup.) This will be detected by the system and causethe light to turn on.If you experience one or more of these conditions,change the fuel brand you use. It will require atleast one full tank of the proper fuel to turn thelight off.If none of the above steps have made the light turnoff, your dealer can check the vehicle. Your dealerhas the proper test equipment and diagnostic toolsto fix any mechanical or electrical problems thatmay have developed.

Emissions Inspection and MaintenanceProgramsSome state/provincial and local governments haveor may begin programs to inspect the emissioncontrol equipment on your vehicle. Failure to passthis inspection could prevent you from getting avehicle registration.

Here are some things you need to know in orderto help your vehicle pass an inspection:

Your vehicle will not pass this inspection if thecheck engine light is on or not working properly.

Your vehicle will not pass this inspection if the OBD(on-board diagnostic) system determines thatcritical emission control systems have not beencompletely diagnosed by the system. The vehiclewould be considered not ready for inspection. Thiscan happen if you have recently replaced yourbattery or if your battery has run down. Thediagnostic system is designed to evaluate criticalemission control systems during normal driving.This may take several days of routine driving. If youhave done this and your vehicle still does not passthe inspection for lack of OBD system readiness,your dealer can prepare the vehicle for inspection.

Here are some things that some owners askabout. None of these show a problem with yourfuel gage:

• At the service station, the gas pump shuts offbefore the gage reads full.

• It takes more (or less) fuel to fill up than thegage indicated. For example, the gage mayhave indicated half full, but it took more(or less) than half the tank’s capacity to fill it.

• The gage moves up a little when you turn acorner, speed up or make a hard stop.

• The gage does not go back to empty whenyou turn off the ignition.

Each trip odometer can be reset to zero separatelyby pressing the set/reset button while the desiredtrip odometer is displayed.

The trip odometer has a feature called theretro-active reset. This can be used to set the tripodometer to the number of miles (kilometers) drivensince the ignition was last turned on. This can beused if the trip odometer is not reset at thebeginning of the trip.

To use the retro-active reset feature, press and holdthe set/reset button for at least four seconds. Thetrip odometer will display the number of miles (mi)or kilometers (km) driven since the ignition was lastturned on and the vehicle was moving. Once thevehicle begins moving, the trip odometer willaccumulate mileage. For example, if the vehiclewas driven 5 miles (8 km) before it is started again,and then the retro-active reset feature is activated,the display will show 5 miles (8 km). As the vehiclebegins moving, the display will then increase to5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.

If the retro-active reset feature is activated after thevehicle is started, but before it begins moving, thedisplay will show the number of miles (mi) orkilometers (km) that were driven during the lastignition cycle.

Fuel RangePress the trip/fuel button until FUEL RANGEdisplays. This display shows the approximatenumber of remaining miles (mi) or kilometers (km)the vehicle can be driven without refueling.

The fuel range estimate is based on an average ofthe vehicle’s fuel economy over recent drivinghistory and the amount of fuel remaining in the fueltank. This estimate will change if driving conditionschange. For example, if driving in traffic and makingfrequent stops, this display may read one number,but if the vehicle is driven on a freeway, the numbermay change even though the same amount of fuelis in the fuel tank. This is because different drivingconditions produce different fuel economies.Generally, freeway driving produces better fueleconomy than city driving.

If your vehicle is low on fuel, the FUEL LEVELLOW message will be displayed. See “FUELLEVEL LOW” under DIC Warnings and Messageson page 221 for more information.

Using an MP3

MP3 CD-R or CD-RW DiscThe radio plays MP3 files that were recorded on aCD-R or CD-RW disc. The files can be recordedwith the following fixed bit rates: 32 kbps, 40 kbps,56 kbps, 64 kbps, 80 kbps, 96 kbps, 112 kbps,128 kbps, 160 kbps, 192 kbps, 224 kbps,256 kbps, and 320 kbps or a variable bit rate.Song title, artist name, and album can displaywhen files are recorded using ID3 tagsversion 1 and 2.

Compressed AudioThe radio also plays discs that contain bothuncompressed CD audio (.CDA files) and MP3/WMA files. By default the radio reads only theuncompressed audio and ignores the MP3 files.Pressing the CAT (category) button togglesbetween compressed and uncompressed audioformat.

MP3 FormatIf you burn your own MP3 disc on a personalcomputer:

• Make sure the MP3 files are recorded on aCD-R or CD-RW disc.

• Avoid mixing standard audio and MP3 files onone disc.

• Make sure the CD does not have more than50 folders, 50 playlists, and 255 files to readand play.

• Create a folder structure that makes it easy tofind songs while driving. Organize songs byalbums using one folder for each album. Eachfolder or album should contain 18 songsor less.

• Avoid subfolders. The system can support upto 8 subfolders deep, however, keep the totalnumber of folders to a minimum in order toreduce the complexity and confusion in tryingto locate a particular folder during playback.

• Make sure playlists have a .mp3 or .wplextension (other file extensions may not work).

262

Page 263: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

• Minimize the length of the file, folder or playlistnames. Long file, folder, or playlist names, or acombination of a large number of files andfolders, or playlists can cause the player to beunable to play up to the maximum number offiles, folders, playlists, or sessions. If you wishto play a large number of files, folders, playlistsor sessions, minimize the length of the file,folder or playlist name. Long names also takeup more space on the display, potentiallygetting cut off.

• Finalize the audio disc before you burn it.Trying to add music to an existing disc cancause the disc not to function in the player.

Change playlists by using the previous and nextfolder buttons, the tuner knob, or the seek buttons.An MP3 CD-R that was recorded using no filefolders can also be played. If a CD-R contains morethan the maximum of 50 folders, 50 playlists, and255 files, the player lets you access and navigateup to the maximum, but all items over the maximumcannot be accessed.

Root DirectoryThe root directory of the CD-R is treated as a folder.If the root directory has compressed audio files, thedirectory displays as F1 ROOT. All files containeddirectly under the root directory are accessed priorto any root directory folders. However, playlists (Px)are always accessed before root folders or files.

Empty Directory or FolderIf a root directory or a folder exists somewherein the file structure that contains only folders/subfolders and no compressed files directlybeneath them, the player advances to the nextfolder in the file structure that contains compressedaudio files. The empty folder is not numbered ordisplayed.

263

Page 264: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

No FolderWhen the CD-R contains only compressed files, thefiles are located under the root folder. The next andprevious folder functions do not function on a CD-Rthat was recorded without folders or playlists. Whendisplaying the name of the folder the radiodisplays ROOT.

When the CD-R contains only playlists andcompressed audio files, but no folders, all files arelocated under the root folder. The folder down andthe folder up buttons searches playlists (Px) firstand then goes to the root folder. When the radiodisplays the name of the folder the radiodisplays ROOT.

Order of PlayTracks recorded to the CD-R are played in thefollowing order:

• Play begins from the first track in the firstplaylist and continues sequentially throughall tracks in each playlist. When the last trackof the last playlist has played, play continuesfrom the first track of the first playlist.

• Play begins from the first track in the firstfolder and continues sequentially throughall tracks in each folder. When the last trackof the last folder has played, play continuesfrom the first track of the first folder.

When play enters a new folder, the display doesnot automatically show the new folder name unlessyou have chosen the folder mode as the defaultdisplay. The new track name displays.

File System and NamingThe song name that displays is the song name thatis contained in the ID3 tag. If the song name is notpresent in the ID3 tag, then the radio displays thefile name without the extension (such as .mp3) asthe track name.

Track names longer than 32 characters or fourpages are shortened. The display does not showparts of words on the last page of text and theextension of the filename is not displayed.

Preprogrammed PlaylistsPreprogrammed playlists that were created usingWinAmp™, MusicMatch™, or Real Jukebox™software can be accessed, however, you do nothave playlist editing capability using the radio.These playlists are treated as special folderscontaining compressed audio song files.

Playing an MP3Insert a CD-R partway into the slot (Single CDPlayer), or press the load button and wait for themessage to insert disc (Six-Disc CD Player), labelside up. The player pulls it in, and the CD-R shouldbegin playing.

If the ignition or radio is turned off with a CD-R inthe player it stays in the player. When the ignition orradio is turned on, the CD-R starts to play where itstopped, if it was the last selected audio source.

As each new track starts to play, the track numberand song title displays.

The CD player can play the smaller 3 inch (8 cm)single CD-Rs with an adapter ring. Full-size CD-Rsand the smaller CD-Rs are loaded in the samemanner.

If playing a CD-R, the sound quality can be reduceddue to CD-R quality, the method of recording, thequality of the music that has been recorded, and theway the CD-R has been handled. There can be anincrease in skipping, difficulty in finding tracks,and/or difficulty in loading and ejecting. If theseproblems occur, check the bottom surface of theCD. If the surface of the CD is damaged, such ascracked, broken, or scratched, the CD will not playproperly. If the surface of the CD is soiled, see Careof Your CDs on page 273 for more information.

Your Driving, the Road, andYour Vehicle

Defensive DrivingThe best advice anyone can give about driving is:Drive defensively.

Please start with a very important safety device inyour vehicle: Buckle up. See Safety Belts: TheyAre for Everyone on page 19.

{CAUTION:

Defensive driving really means “Be readyfor anything.” On city streets, rural roads,or expressways, it means “Always expectthe unexpected.” Assume that pedestriansor other drivers are going to be carelessand make mistakes. Anticipate what theymight do and be ready. Rear-end collisionsare about the most preventable ofaccidents. Yet they are common. Allowenough following distance. Defensivedriving requires that a driver concentrateon the driving task. Anything that distractsfrom the driving task makes properdefensive driving more difficult and caneven cause a collision, with resultinginjury. Ask a passenger to help do thesethings, or pull off the road in a safe place todo them. These simple defensive drivingtechniques could save your life.

Drunken DrivingDeath and injury associated with drinking anddriving is a national tragedy. It is the numberone contributor to the highway death toll,claiming thousands of victims every year.

Alcohol affects four things that anyone needs todrive a vehicle:

• Judgment

• Muscular Coordination

• Vision

• Attentiveness

Police records show that almost half of all motorvehicle-related deaths involve alcohol. In mostcases, these deaths are the result of someone whowas drinking and driving. In recent years, morethan 16,000 annual motor vehicle-related deathshave been associated with the use of alcohol, withmore than 300,000 people injured.

Many adults — by some estimates, nearly halfthe adult population — choose never to drinkalcohol, so they never drive after drinking.For persons under 21, it is against the law inevery U.S. state to drink alcohol. There are goodmedical, psychological, and developmentalreasons for these laws.

The obvious way to eliminate the leading highwaysafety problem is for people never to drinkalcohol and then drive. But what if people do?How much is “too much” if someone plansto drive? It is a lot less than many might think.Although it depends on each person and situation,here is some general information on the problem.

The Blood Alcohol Concentration (BAC) ofsomeone who is drinking depends uponfour things:

• The amount of alcohol consumed

• The drinker’s body weight

• The amount of food that is consumed beforeand during drinking

• The length of time it has taken the drinker toconsume the alcohol

277

Page 278: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

According to the American Medical Association,a 180 lb (82 kg) person who drinks three 12 ounce(355 ml) bottles of beer in an hour will end upwith a BAC of about 0.06 percent. The personwould reach the same BAC by drinking three4 ounce (120 ml) glasses of wine or three mixeddrinks if each had 1-1/2 ounces (45 ml) ofliquors like whiskey, gin, or vodka.

It is the amount of alcohol that counts. For example,if the same person drank three double martinis(3 ounces or 90 ml of liquor each) within an hour,the person’s BAC would be close to 0.12 percent.A person who consumes food just before or duringdrinking will have a somewhat lower BAC level.

There is a gender difference, too. Womengenerally have a lower relative percentage ofbody water than men. Since alcohol is carried inbody water, this means that a woman generallywill reach a higher BAC level than a man ofher same body weight will when each has thesame number of drinks.

The law in most U.S. states, and throughoutCanada, sets the legal limit at 0.08 percent.In some other countries, the limit is even lower.For example, it is 0.05 percent in both Franceand Germany. The BAC limit for all commercialdrivers in the United States is 0.04 percent.

The BAC will be over 0.10 percent after three tosix drinks (in one hour). Of course, as we haveseen, it depends on how much alcohol is in thedrinks, and how quickly the person drinks them.

278

Page 279: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

But the ability to drive is affected well below a BACof 0.10 percent. Research shows that the drivingskills of many people are impaired at a BACapproaching 0.05 percent, and that the effects areworse at night. All drivers are impaired at BAClevels above 0.05 percent. Statistics show that thechance of being in a collision increases sharply fordrivers who have a BAC of 0.05 percent or above.A driver with a BAC level of 0.06 percent hasdoubled his or her chance of having a collision. At aBAC level of 0.10 percent, the chance of this driverhaving a collision is 12 times greater; at a level of0.15 percent, the chance is 25 times greater!

The body takes about an hour to rid itself of thealcohol in one drink. No amount of coffee ornumber of cold showers will speed that up.“I will be careful” is not the right answer. What ifthere is an emergency, a need to take suddenaction, as when a child darts into the street?A person with even a moderate BAC mightnot be able to react quickly enough to avoid thecollision.

There is something else about drinking and drivingthat many people do not know. Medical researchshows that alcohol in a person’s system can makecrash injuries worse, especially injuries to thebrain, spinal cord, or heart. This means that whenanyone who has been drinking — driver orpassenger — is in a crash, that person’s chanceof being killed or permanently disabled ishigher than if the person had not been drinking.

{CAUTION:

Drinking and then driving is verydangerous. Your reflexes, perceptions,attentiveness, and judgment can beaffected by even a small amount ofalcohol. You can have a serious — oreven fatal — collision if you drive afterdrinking. Please do not drink and driveor ride with a driver who has beendrinking. Ride home in a cab; or if youare with a group, designate a driverwho will not drink.

Control of a VehicleYou have three systems that make yourvehicle go where you want it to go. They are thebrakes, the steering, and the accelerator. Allthree systems have to do their work at the placeswhere the tires meet the road.

Sometimes, as when you are driving on snow orice, it is easy to ask more of those control systemsthan the tires and road can provide. That meansyou can lose control of your vehicle. See TractionControl System (TCS) on page 283.

Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 325.

BrakingSee Brake System Warning Light on page 201.

Braking action involves perception time andreaction time.

First, you have to decide to push on the brakepedal. That is perception time. Then you have tobring up your foot and do it. That is reaction time.

Average reaction time is about three-fourths of asecond. But that is only an average. It might be lesswith one driver and as long as two or three secondsor more with another. Age, physical condition,alertness, coordination, and eyesight all play a part.So do alcohol, drugs, and frustration. But even inthree-fourths of a second, a vehicle moving at60 mph (100 km/h) travels 66 feet (20 m). Thatcould be a lot of distance in an emergency, sokeeping enough space between your vehicle andothers is important.

And, of course, actual stopping distances varygreatly with the surface of the road, whether it ispavement or gravel; the condition of the road,whether it is wet, dry, or icy; tire tread; thecondition of the brakes; the weight of the vehicle;and the amount of brake force applied.

280

Page 281: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Avoid needless heavy braking. Some people drivein spurts — heavy acceleration followed byheavy braking — rather than keeping pace withtraffic. This is a mistake. The brakes may not havetime to cool between hard stops. The brakeswill wear out much faster if you do a lot of heavybraking. If you keep pace with the traffic andallow realistic following distances, you willeliminate a lot of unnecessary braking. That meansbetter braking and longer brake life.

If your vehicle’s engine ever stops while you aredriving, brake normally but do not pump thebrakes. If you do, the pedal may get harder topush down. If the engine stops, you will still havesome power brake assist. But you will use itwhen you brake. Once the power assist is usedup, it may take longer to stop and the brake pedalwill be harder to push.

Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 325.

Anti-Lock Brake System (ABS)Your vehicle has the Anti-Lock Brake System(ABS), an advanced electronic braking systemthat will help prevent a braking skid.

When you start your engine and begin to driveaway, ABS will check itself. You may hear amomentary motor or clicking noise while this testis going on, and you may even notice thatyour brake pedal moves a little. This is normal.

If there is a problemwith ABS, this warninglight will stay on.See Anti-Lock BrakeSystem WarningLight on page 202.

281

Let us say the road is wet and you are drivingsafely. Suddenly, an animal jumps out in front ofyou. You slam on the brakes and continue braking.Here is what happens with ABS:

A computer senses that wheels are slowing down.If one of the wheels is about to stop rolling, thecomputer will separately work the brakes at eachfront wheel and at both rear wheels.

ABS can change the brake pressure faster thanany driver could. The computer is programmedto make the most of available tire and roadconditions. This can help you steer around theobstacle while braking hard.

As you brake, your computer keeps receivingupdates on wheel speed and controls brakingpressure accordingly.

282

Page 283: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Remember: ABS does not change the time youneed to get your foot up to the brake pedal oralways decrease stopping distance. If you get tooclose to the vehicle in front of you, you will not havetime to apply your brakes if that vehicle suddenlyslows or stops. Always leave enough room upahead to stop, even though you have ABS.

Using ABSDo not pump the brakes. Just hold the brake pedaldown firmly and let anti-lock work for you. You mayhear the anti-lock pump or motor operate, and feelthe brake pedal pulsate, but this is normal.

Braking in EmergenciesWith ABS, you can steer and brake at the sametime. In many emergencies, steering can help youmore than even the very best braking.

Traction Control System (TCS)Your vehicle has a traction control system that limitswheel spin. This is especially useful in slippery roadconditions. The system operates only if it sensesthat the front wheels are spinning too much orbeginning to lose traction. When this happens, thesystem works the front brakes and reduces enginepower (by closing the throttle and managing enginespark) to limit wheel spin.

The traction control system and StabiliTrak®

warning light will flash when the traction controlsystem is limiting wheel spin. See Traction ControlSystem (TCS) Warning Light on page 202 formore information. You may feel or hear the systemworking, but this is normal.

If your vehicle is in cruise control when thetraction control system begins to limit wheel spin,the cruise control will automatically disengage.When road conditions allow you to safely useit again, you may re-engage the cruise control.See Cruise Control on page 167 for moreinformation.

When this light and the SERVICE TRACTIONCONTROL message are on, the system will notlimit wheel spin. Adjust your driving accordingly.

The traction control system automaticallycomes on whenever you start your vehicle.To limit wheel spin, especially in slippery roadconditions, you should always leave the systemon. But you can turn the traction control system offif you ever need to.

You can turn the system on or off at any time bypressing the traction control system button locatedon the console. The DIC will display TRACTIONCONTROL OFF when you press the button.

Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 325 for more information.

StabiliTrak® SystemYour vehicle may have this feature. TheStabiliTrak® system is an advanced computercontrolled system that helps the driver maintaindirectional control of the vehicle in difficult drivingconditions. This is accomplished by selectivelyapplying any one of the vehicle’s brakes andreducing engine power. The StabiliTrak® systemcomes on automatically whenever you startyour vehicle. The system cannot be turned off.

The STABILITRAK NOT READY message may bedisplayed in the DIC and the traction control systemand StabiliTrak® warning light on the instrumentpanel cluster will be on after first driving the vehicleand exceeding 19 mph (30 km/h) for 30 seconds.The StabiliTrak® system is off until the light hasturned off. This could take up to 15 minutes.

When this light and the SERVICESTABILITRAK message are on, the system is notoperational. Adjust your driving accordingly.

Panic Brake AssistYour vehicle may have a panic brake assist systemthat monitors the intention of the driver whilebraking. If the system senses that the driver hasapplied hard/fast pressure to the brake pedal, thesystem will generate additional pressure, making iteasier for the driver to maintain brake application.When this happens the brake pedal will feel easierto push. Just hold the brake pedal down firmly andlet the system work for you. You may feel thebrakes vibrate, or you may notice some noise butthis is normal. The brakes will return to normaloperation after the brake pedal has been released.

Steering

Power SteeringIf you lose power steering assist because theengine stops or the system is not functioning,you can steer but it will take much more effort.

Steering TipsIt is important to take curves at a reasonablespeed.

A lot of the “driver lost control” accidents mentionedon the news happen on curves. Here is why:

Experienced driver or beginner, each of us issubject to the same laws of physics when driving oncurves. The traction of the tires against the roadsurface makes it possible for the vehicle to changeits path when you turn the front wheels. If there isno traction, inertia will keep the vehicle going in thesame direction. If you have ever tried to steer avehicle on wet ice, you will understand this.

285

Page 286: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

The traction you can get in a curve depends onthe condition of your tires and the road surface,the angle at which the curve is banked, andyour speed. While you are in a curve, speed isthe one factor you can control.

Suppose you are steering through a sharp curve.Then you suddenly accelerate. Both controlsystems — steering and acceleration — haveto do their work where the tires meet the road.Adding the sudden acceleration can demandtoo much of those places. You can lose control.See Traction Control System (TCS) on page 283and StabiliTrak® System on page 284.

What should you do if this ever happens?Ease up on the accelerator pedal, steer the vehiclethe way you want it to go, and slow down.

Speed limit signs near curves warn that you shouldadjust your speed. Of course, the posted speedsare based on good weather and road conditions.Under less favorable conditions you will want to goslower.

If you need to reduce your speed as you approacha curve, do it before you enter the curve, whileyour front wheels are straight ahead.

Try to adjust your speed so you can “drive”through the curve. Maintain a reasonable, steadyspeed. Wait to accelerate until you are out ofthe curve, and then accelerate gently intothe straightaway.

Adding non-GM accessories can affect yourvehicle’s performance. See Accessories andModifications on page 325.

Steering in EmergenciesThere are times when steering can be moreeffective than braking. For example, you comeover a hill and find a truck stopped in your lane,or a car suddenly pulls out from nowhere, ora child darts out from between parked cars andstops right in front of you. You can avoidthese problems by braking — if you can stop intime. But sometimes you cannot; there is not room.That is the time for evasive action — steeringaround the problem.

Your vehicle can perform very well in emergencieslike these. First apply your brakes.

See Braking on page 280. It is better to remove asmuch speed as you can from a possible collision.Then steer around the problem, to the left orright depending on the space available.

An emergency like this requires close attention anda quick decision. If you are holding the steeringwheel at the recommended 9 and 3 o’clockpositions, you can turn it a full 180 degrees veryquickly without removing either hand. But youhave to act fast, steer quickly, and just as quicklystraighten the wheel once you have avoidedthe object.

The fact that such emergency situations are alwayspossible is a good reason to practice defensivedriving at all times and wear safety belts properly.

Off-Road RecoveryYou may find that your right wheels have droppedoff the edge of a road onto the shoulder whileyou are driving.

If the level of the shoulder is only slightly below thepavement, recovery should be fairly easy. Ease offthe accelerator and then, if there is nothing in theway, steer so that your vehicle straddles the edgeof the pavement. You can turn the steering wheelup to one-quarter turn until the right front tirecontacts the pavement edge. Then turn yoursteering wheel to go straight down the roadway.

PassingThe driver of a vehicle about to pass another on atwo-lane highway waits for just the right moment,accelerates, moves around the vehicle ahead, thengoes back into the right lane again. A simplemaneuver?

Not necessarily! Passing another vehicle on atwo-lane highway is a potentially dangerous move,since the passing vehicle occupies the samelane as oncoming traffic for several seconds.A miscalculation, an error in judgment, or a briefsurrender to frustration or anger can suddenlyput the passing driver face to face with the worstof all traffic accidents — the head-on collision.

So here are some tips for passing:

• Drive ahead. Look down the road, to thesides, and to crossroads for situationsthat might affect your passing patterns. If youhave any doubt whatsoever about makinga successful pass, wait for a better time.

288

Page 289: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

• Watch for traffic signs, pavement markings, andlines. If you can see a sign up ahead that mightindicate a turn or an intersection, delay yourpass. A broken center line usually indicates it isall right to pass, providing the road ahead isclear. Never cross a solid line on your side ofthe lane or a double solid line, even if the roadseems empty of approaching traffic.

• Do not get too close to the vehicle you want topass while you are awaiting an opportunity. Forone thing, following too closely reduces yourarea of vision, especially if you are following alarger vehicle. Also, you will not have adequatespace if the vehicle ahead suddenly slows orstops. Keep back a reasonable distance.

• When it looks like a chance to pass is comingup, start to accelerate but stay in the right laneand do not get too close. Time your move soyou will be increasing speed as the time comesto move into the other lane. If the way is clear topass, you will have a running start that morethan makes up for the distance you would loseby dropping back. And if something happens tocause you to cancel your pass, you need onlyslow down and drop back again and wait foranother opportunity.

• If other vehicles are lined up to pass a slowvehicle, wait your turn. But take care thatsomeone is not trying to pass you as you pullout to pass the slow vehicle. Remember toglance over your shoulder and check theblind spot.

• Check your vehicle’s mirrors, glance over yourshoulder, and start your left lane change signalbefore moving out of the right lane to pass.When you are far enough ahead of the passedvehicle to see its front in your vehicle’s insidemirror, activate the right lane change signal andmove back into the right lane. Remember thatyour vehicle’s passenger side outside mirror isconvex. The vehicle you just passed may seemto be farther away from you than it really is.

• Try not to pass more than one vehicle at a timeon two-lane roads. Reconsider before passingthe next vehicle.

• Do not overtake a slowly moving vehicle toorapidly. Even though the brake lamps are notflashing, it may be slowing down or startingto turn.

• If you are being passed, make it easy for thefollowing driver to get ahead of you. Perhapsyou can ease a little to the right.

Loss of ControlLet us review what driving experts say about whathappens when the three control systems — brakes,steering, and acceleration — do not have enoughfriction where the tires meet the road to do what thedriver has asked.

In any emergency, do not give up. Keep trying tosteer and constantly seek an escape route orarea of less danger.

SkiddingIn a skid, a driver can lose control of the vehicle.Defensive drivers avoid most skids by takingreasonable care suited to existing conditions, andby not overdriving those conditions. But skidsare always possible.

The three types of skids correspond to yourvehicle’s three control systems. In the braking skid,your wheels are not rolling. In the steering orcornering skid, too much speed or steering in acurve causes tires to slip and lose cornering force.And in the acceleration skid, too much throttlecauses the driving wheels to spin.

A cornering skid is best handled by easing yourfoot off the accelerator pedal.

Remember: Any traction control system helpsavoid only the acceleration skid. If your tractioncontrol system is off, then an accelerationskid is also best handled by easing your foot offthe accelerator pedal.

If your vehicle starts to slide, ease your foot offthe accelerator pedal and quickly steer theway you want the vehicle to go. If you startsteering quickly enough, your vehicle maystraighten out. Always be ready for a second skidif it occurs.

Of course, traction is reduced when water, snow,ice, gravel, or other material is on the road.For safety, you will want to slow down and adjustyour driving to these conditions. It is importantto slow down on slippery surfaces becausestopping distance will be longer and vehicle controlmore limited.

While driving on a surface with reduced traction, tryyour best to avoid sudden steering, acceleration, orbraking, including reducing vehicle speed byshifting to a lower gear. Any sudden changes couldcause the tires to slide. You may not realize thesurface is slippery until your vehicle is skidding.Learn to recognize warning clues — such asenough water, ice, or packed snow on the road tomake a mirrored surface — and slow down whenyou have any doubt.

Remember: Any Anti-Lock Brake System (ABS)helps avoid only the braking skid.

Driving at NightNight driving is more dangerous than day driving.One reason is that some drivers are likely tobe impaired — by alcohol or drugs, with nightvision problems, or by fatigue.

Here are some tips on night driving.

• Drive defensively.

• Do not drink and drive.

• Adjust the inside rearview mirror to reduce theglare from headlamps behind you.

• Since you cannot see as well, you may needto slow down and keep more space betweenyou and other vehicles.

• Slow down, especially on higher speed roads.Your vehicle’s headlamps can light up only somuch road ahead.

• In remote areas, watch for animals.

• If you are tired, pull off the road in a safeplace and rest.

291

No one can see as well at night as in the daytime.But as we get older these differences increase.A 50-year-old driver may require at least twice asmuch light to see the same thing at night as a20-year-old.

What you do in the daytime can also affect yournight vision. For example, if you spend theday in bright sunshine you are wise to wearsunglasses. Your eyes will have less troubleadjusting to night. But if you are driving, do notwear sunglasses at night. They may cut down onglare from headlamps, but they also make alot of things invisible.

You can be temporarily blinded by approachingheadlamps. It can take a second or two, oreven several seconds, for your eyes to re-adjustto the dark. When you are faced with severe glare,as from a driver who does not lower the highbeams, or a vehicle with misaimed headlamps,slow down a little. Avoid staring directly intothe approaching headlamps.

Keep the windshield and all the glass on yourvehicle clean — inside and out. Glare at night ismade much worse by dirt on the glass. Eventhe inside of the glass can build up a film causedby dust. Dirty glass makes lights dazzle andflash more than clean glass would, making thepupils of your eyes contract repeatedly.

Remember that the headlamps light up far less of aroadway when you are in a turn or curve. Keep youreyes moving; that way, it is easier to pick out dimlylighted objects. Just as the headlamps should bechecked regularly for proper aim, so should youreyes be examined regularly. Some drivers sufferfrom night blindness — the inability to see in dimlight — and are not even aware of it.

Driving in Rain and on Wet Roads

Rain and wet roads can mean driving trouble. On awet road, you cannot stop, accelerate, or turn aswell because your tire-to-road traction is not asgood as on dry roads. And, if your tires do not havemuch tread left, you will get even less traction.

It is always wise to go slower and be cautious if rainstarts to fall while you are driving. The surface mayget wet suddenly when your reflexes are tuned fordriving on dry pavement.

The heavier the rain, the harder it is to see.Even if your windshield wiper blades are in goodshape, a heavy rain can make it harder to seeroad signs and traffic signals, pavement markings,the edge of the road, and even people walking.

It is wise to keep your windshield wiping equipmentin good shape and keep your windshield washerfluid reservoir filled with washer fluid. Replace yourwindshield wiper inserts when they show signsof streaking or missing areas on the windshield,or when strips of rubber start to separate fromthe inserts.

{CAUTION:

Wet brakes can cause accidents. Theymay not work as well in a quick stop andmay cause pulling to one side. You couldlose control of the vehicle.

After driving through a large puddle ofwater or a car wash, apply your brake pedallightly until your brakes work normally.

Driving too fast through large water puddles oreven going through some car washes can causeproblems, too. The water may affect your brakes.Try to avoid puddles. But if you cannot, try to slowdown before you hit them.

HydroplaningHydroplaning is dangerous. So much water canbuild up under your tires that they can actually rideon the water. This can happen if the road is wetenough and you are going fast enough. When yourvehicle is hydroplaning, it has little or no contactwith the road.

Hydroplaning does not happen often. But it canif your tires do not have much tread or if thepressure in one or more is low. It can happen if alot of water is standing on the road. If you cansee reflections from trees, telephone poles,or other vehicles, and raindrops dimple the water’ssurface, there could be hydroplaning.

Hydroplaning usually happens at higher speeds.There just is not a hard and fast rule abouthydroplaning. The best advice is to slow downwhen it is raining.

Driving Through Deep Standing Water

Notice: If you drive too quickly through deeppuddles or standing water, water can come inthrough your engine’s air intake and badlydamage your engine. Never drive through waterthat is slightly lower than the underbody of yourvehicle. If you cannot avoid deep puddles orstanding water, drive through them very slowly.

Driving Through Flowing Water

{CAUTION:

Flowing or rushing water creates strongforces. If you try to drive through flowingwater, as you might at a low watercrossing, your vehicle can be carried away.

CAUTION: (Continued)

CAUTION: (Continued)

As little as six inches of flowing watercan carry away a smaller vehicle. If thishappens, you and other vehicle occupantscould drown. Do not ignore police warningsigns, and otherwise be very cautiousabout trying to drive through flowing water.

Some Other Rainy Weather Tips• Besides slowing down, allow some extra

following distance. And be especially carefulwhen you pass another vehicle. Allow yourselfmore clear room ahead, and be prepared tohave your view restricted by road spray.

• Have good tires with proper tread depth.See Tires on page 385.

City Driving

One of the biggest problems with city streets isthe amount of traffic on them. You will wantto watch out for what the other drivers are doingand pay attention to traffic signals.

Here are ways to increase your safety in citydriving:

• Know the best way to get to where you aregoing. Get a city map and plan your tripinto an unknown part of the city just as youwould for a cross-country trip.

• Try to use the freeways that rim and crisscrossmost large cities. You will save time andenergy. See Freeway Driving on page 297.

• Treat a green light as a warning signal.A traffic light is there because the corneris busy enough to need it. When a light turnsgreen, and just before you start to move,check both ways for vehicles that have notcleared the intersection or may be runningthe red light.

Freeway Driving

Mile for mile, freeways — also called thruways,parkways, expressways, turnpikes, orsuperhighways — are the safest of all roads.But they have their own special rules.

The most important advice on freeway drivingis: Keep up with traffic and keep to the right.Drive at the same speed most of the other driversare driving. Too-fast or too-slow driving breaksa smooth traffic flow. Treat the left lane ona freeway as a passing lane.

At the entrance, there is usually a ramp that leadsto the freeway. If you have a clear view of thefreeway as you drive along the entrance ramp, youshould begin to check traffic. Try to determinewhere you expect to blend with the flow. Try tomerge into the gap at close to the prevailing speed.Switch on your turn signal, check your mirrors, andglance over your shoulder as often as necessary.Try to blend smoothly with the traffic flow.

Once you are on the freeway, adjust your speedto the posted limit or to the prevailing rate if itis slower. Stay in the right lane unless you wantto pass.

297

Page 298: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Before changing lanes, check your mirrors.Then use your turn signal.

Just before you leave the lane, glance quicklyover your shoulder to make sure there is notanother vehicle in your blind spot.

Once you are moving on the freeway, makecertain you allow a reasonable following distance.

Expect to move slightly slower at night.

When you want to leave the freeway, move to theproper lane well in advance. If you miss yourexit, do not, under any circumstances, stop andback up. Drive on to the next exit.

The exit ramp can be curved, sometimes quitesharply. The exit speed is usually posted. Reduceyour speed according to your speedometer, notto your sense of motion. After driving for anydistance at higher speeds, you may tend to thinkyou are going slower than you actually are.

Before Leaving on a Long TripMake sure you are ready. Try to be well rested.If you must start when you are not fresh — suchas after a day’s work — do not plan to maketoo many miles that first part of the journey.Wear comfortable clothing and shoes you caneasily drive in.

Is your vehicle ready for a long trip? If you keep itserviced and maintained, it is ready to go. If itneeds service, have it done before starting out.Of course, you will find experienced and ableservice experts in GM dealerships all acrossNorth America. They will be ready and willing tohelp if you need it.

• Windshield Washer Fluid: Is the reservoir full?Are all windows clean inside and outside?

• Wiper Blades: Are they in good shape?

• Fuel, Engine Oil, Other Fluids: Have youchecked all levels?

• Lamps: Are they all working? Are the lensesclean?

• Tires: They are vitally important to a safe,trouble-free trip. Is the tread good enough forlong-distance driving? Are the tires all inflatedto the recommended pressure?

• Weather Forecasts: What is the weatheroutlook along your route? Should you delayyour trip a short time to avoid a major stormsystem?

• Maps: Do you have up-to-date maps?

Highway HypnosisIs there actually such a condition as highwayhypnosis? Or is it just plain falling asleep at thewheel? Call it highway hypnosis, lack ofawareness, or whatever.

There is something about an easy stretch of roadwith the same scenery, along with the hum of thetires on the road, the drone of the engine, and therush of the wind against the vehicle that can makeyou sleepy. Do not let it happen to you! If it does,your vehicle can leave the road in less than asecond, and you could crash and be injured.

What can you do about highway hypnosis?First, be aware that it can happen.

Then here are some tips:

• Make sure your vehicle is well ventilated,with a comfortably cool interior.

• Keep your eyes moving. Scan the road aheadand to the sides. Check your rearview mirrorsand your instruments frequently.

• If you get sleepy, pull off the road into a rest,service, or parking area and take a nap, getsome exercise, or both. For safety, treatdrowsiness on the highway as an emergency.

Driving on steep hills or mountains is differentfrom driving in flat or rolling terrain.

If you drive regularly in steep country, or if you areplanning to visit there, here are some tips thatcan make your trips safer and more enjoyable.

• Keep your vehicle in good shape. Checkall fluid levels and also the brakes, tires,cooling system, and transaxle. These partscan work hard on mountain roads.

{CAUTION:

If you do not shift down, your brakescould get so hot that they would not workwell. You would then have poor braking oreven none going down a hill. You couldcrash. Shift down to let your engine assistyour brakes on a steep downhill slope.

• Know how to go down hills. The most importantthing to know is this: let your engine do some ofthe slowing down. Shift to a lower gear whenyou go down a steep or long hill.

• Know how to go uphill. Drive in the highest gearpossible.

• Stay in your own lane when driving on two-laneroads in hills or mountains. Do not swing wideor cut across the center of the road. Drive atspeeds that let you stay in your own lane.

• As you go over the top of a hill, be alert. Therecould be something in your lane, like a stalledcar or an accident.

• You may see highway signs on mountains thatwarn of special problems. Examples are longgrades, passing or no-passing zones, a fallingrocks area, or winding roads. Be alert to theseand take appropriate action.

Winter Driving

Here are some tips for winter driving:

• Have your vehicle in good shape for winter.

• You may want to put winter emergencysupplies in your trunk.

Also see Tires on page 385.

Include an ice scraper, a small brush or broom, asupply of windshield washer fluid, a rag, somewinter outer clothing, a small shovel, a flashlight,a red cloth, and a couple of reflective warningtriangles. And, if you will be driving under severeconditions, include a small bag of sand, apiece of old carpet, or a couple of burlap bagsto help provide traction. Be sure you properlysecure these items in your vehicle.

Driving on Snow or IceMost of the time, those places where the tiresmeet the road probably have good traction.However, if there is snow or ice between the tiresand the road, you can have a very slipperysituation. You will have a lot less traction, or grip,and will need to be very careful.

What is the worst time for this? Wet ice. Very coldsnow or ice can be slick and hard to drive on.

But wet ice can be even more trouble because itmay offer the least traction of all. You can getwet ice when it is about freezing, 32°F (0°C), andfreezing rain begins to fall. Try to avoid drivingon wet ice until salt and sand crews can get there.

Whatever the condition — smooth ice, packed,blowing, or loose snow — drive with caution.

If you have the Traction Control System (TCS), itwill improve your ability to accelerate whendriving on a slippery road. Even if your vehicle hasTCS you will want to slow down and adjust yourdriving to the road conditions. Under certainconditions, you may want to turn the TCS off, suchas when driving through deep snow and loosegravel, to help maintain vehicle motion atlower speeds. See Traction Control System (TCS)on page 283.

If you do not have TCS, accelerate gently. Try notto break the fragile traction. If you accelerate toofast, the drive wheels will spin and polish thesurface under the tires even more.

303

Page 304: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

The Anti-Lock Brake System (ABS) improves yourvehicle’s stability when you make a hard stopon a slippery road. Even though you have ABS,you will want to begin stopping sooner thanyou would on dry pavement. See Anti-Lock BrakeSystem (ABS) on page 281.

• Allow greater following distance on anyslippery road.

• Watch for slippery spots. The road might befine until you hit a spot that is covered withice. On an otherwise clear road, ice patchesmay appear in shaded areas where thesun cannot reach, such as around clumps oftrees, behind buildings, or under bridges.Sometimes the surface of a curve or anoverpass may remain icy when thesurrounding roads are clear. If you see apatch of ice ahead of you, brake before youare on it. Try not to brake while you areactually on the ice, and avoid sudden steeringmaneuvers.

If You Are Caught in a BlizzardIf you are stopped by heavy snow, you could be ina serious situation. You should probably staywith your vehicle unless you know for sure that youare near help and you can hike through thesnow. Here are some things to do to summonhelp and keep yourself and your passengers safe:

• Turn on your hazard flashers.

• Tie a red cloth to your vehicle to alert policethat you have been stopped by the snow.

• Put on extra clothing or wrap a blanket aroundyou. If you do not have blankets or extraclothing, make body insulators fromnewspapers, burlap bags, rags, floormats — anything you can wrap aroundyourself or tuck under your clothing tokeep warm.

304

You can run the engine to keep warm, but becareful.

{CAUTION:

Snow can trap exhaust gases underyour vehicle. This can cause deadly CO(carbon monoxide) gas to get inside.CO could overcome you and kill you.You cannot see it or smell it, so you mightnot know it is in your vehicle. Clear awaysnow from around the base of yourvehicle, especially any that is blockingyour exhaust pipe. And check aroundagain from time to time to be sure snowdoes not collect there.

Open a window just a little on the side ofthe vehicle that is away from the wind.This will help keep CO out.

Run your engine only as long as you must. Thissaves fuel. When you run the engine, make it goa little faster than just idle. That is, push theaccelerator slightly. This uses less fuel for the heatthat you get and it keeps the battery charged.

305

Page 306: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

You will need a well-charged battery to restart thevehicle, and possibly for signaling later on withyour headlamps. Let the heater run for a while.

Then, shut the engine off and close the windowalmost all the way to preserve the heat. Startthe engine again and repeat this only when youfeel really uncomfortable from the cold. But do it aslittle as possible. Preserve the fuel as long asyou can. To help keep warm, you can get out ofthe vehicle and do some fairly vigorous exercisesevery half hour or so until help comes.

If Your Vehicle is Stuck in Sand,Mud, Ice, or SnowIn order to free your vehicle when it is stuck,you will need to spin the wheels, but you do notwant to spin your wheels too fast. The methodknown as rocking can help you get out when youare stuck, but you must use caution.

{CAUTION:

If you let your vehicle’s tires spin at highspeed, they can explode, and you or otherscould be injured. And, the transaxle orother parts of the vehicle can overheat.That could cause an engine compartmentfire or other damage. When you are stuck,spin the wheels as little as possible. Do notspin the wheels above 35 mph (55 km/h) asshown on the speedometer.

Notice: Spinning the wheels can destroy partsof your vehicle as well as the tires. If you spinthe wheels too fast while shifting the transaxleback and forth, you can destroy the transaxle.See Rocking Your Vehicle to Get It Out onpage 307.

For information about using tire chains on yourvehicle, see Tire Chains on page 406.

Rocking Your Vehicle to Get It OutFirst, turn the steering wheel left and right.That will clear the area around the front wheels.If your vehicle has traction control, you should turnthe traction control system off. See TractionControl System (TCS) on page 283. Then shiftback and forth between REVERSE (R) anda forward gear, spinning the wheels as little aspossible. Release the accelerator pedal while youshift, and press lightly on the accelerator pedalwhen the transaxle is in gear. By slowly spinningthe wheels in the forward and reverse directions,you will cause a rocking motion that may freeyour vehicle. If that does not get your vehicle outafter a few tries, it may need to be towed out.If your vehicle does need to be towed out,see Towing Your Vehicle on page 313.

Loading Your VehicleIt is very important to know how much weightyour vehicle can carry. This weight is called thevehicle capacity weight and includes the weight ofall occupants, cargo, and all nonfactory-installedoptions. Two labels on your vehicle show howmuch weight it may properly carry; the Tireand Loading Information label and theCertification label.

{CAUTION:

Do not load your vehicle any heavier thanthe Gross Vehicle Weight Rating (GVWR),or either the maximum front or rear GrossAxle Weight Rating (GAWR). If you do,parts on your vehicle can break, and itcan change the way your vehicle handles.These could cause you to lose controland crash. Also, overloading can shortenthe life of your vehicle.

Tire and Loading Information Label

A vehicle specific Tire and Loading Informationlabel is attached to the vehicle’s center pillar(B-pillar). With the driver’s door open, you will findthe label attached below the door lock post (striker).The Tire and Loading Information label shows thenumber of occupant seating positions (A), and themaximum vehicle capacity weight (B) in kilogramsand pounds.

The Tire and Loading Information label also showsthe tire size of the original equipment tires (C) andthe recommended cold tire inflation pressures (D).For more information on tires and inflation see Tireson page 385 and Inflation - Tire Pressure onpage 392.

There is also important loading information on theCertification label. It tells you the Gross VehicleWeight Rating (GVWR) and the Gross Axle WeightRating (GAWR) for the front and rear axle; seeCertification Label later in this section.

Steps for Determining Correct Load Limit1. Locate the statement “The combined

weight of occupants and cargo should neverexceed XXX kg or XXX lbs” on your vehicleplacard.

2. Determine the combined weight of the driverand passengers that will be riding in yourvehicle.

3. Subtract the combined weight of the driverand passengers from XXX kg or XXX lbs.

4. The resulting figure equals the availableamount of cargo and luggage load capacity.For example, if the “XXX” amount equals1400 lbs and there will be five 150 lbpassengers in your vehicle, the amount ofavailable cargo and luggage load capacity is650 lbs (1400 − 750 (5 x 150) = 650 lbs).

5. Determine the combined weight of luggageand cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculated inStep 4.

6. If your vehicle will be towing a trailer, the loadfrom your trailer will be transferred to yourvehicle. Consult this manual to determine howthis reduces the available cargo and luggageload capacity of your vehicle.If your vehicle can tow a trailer, see Towing aTrailer on page 315 for important informationon towing a trailer, towing safety rules,and trailering tips.

If you put things inside your vehicle, like suitcases,tools, packages, or anything else, they will goas fast as the vehicle goes. If you have to stop orturn quickly, or if there is a crash, they willkeep going.

{CAUTION:

Things you put inside your vehicle canstrike and injure people in a sudden stopor turn, or in a crash.

• Put things in the trunk of your vehicle.In a trunk, put them as far forward asyou can. Try to spread the weightevenly.

• Never stack heavier things, likesuitcases, inside the vehicle so thatsome of them are above the tops ofthe seats.

• Do not leave an unsecured childrestraint in your vehicle.

• When you carry something inside thevehicle, secure it whenever you can.

Automatic Level ControlThis feature keeps the rear of your vehicle levelas the load changes. It is automatic, you donot need to adjust anything. This type of levelcontrol is fully automatic and will provide a betterleveled riding position as well as better handlingunder a variety of passenger and loadingconditions. An air compressor connected to therear shocks will raise or lower the rear of thevehicle to maintain proper vehicle height.The system is activated when the ignition key isturned to RUN and will automatically adjust vehicleheight thereafter. The system may exhaust(lower vehicle height) for up to ten minutes afterthe ignition key has been turned to OFF. You mayalso hear the air compressor operating whenthe height is being adjusted.

Towing

Towing Your VehicleConsult your dealer or a professional towingservice if you need to have your disabled vehicletowed. See Roadside Assistance Program onpage 466.

If you want to tow your vehicle behind anothervehicle for recreational purposes (such as behinda motorhome), see “Recreational VehicleTowing” following.

Recreational Vehicle TowingRecreational vehicle towing means towing yourvehicle behind another vehicle — such as behind amotorhome. The two most common types ofrecreational vehicle towing are known as “dinghytowing” (towing your vehicle with all four wheelson the ground) and “dolly towing” (towingyour vehicle with two wheels on the ground andtwo wheels up on a device known as a “dolly”).

With the proper preparation and equipment, manyvehicles can be towed in these ways. See“Dinghy Towing” and “Dolly Towing,” following.

Here are some important things to consider beforeyou do recreational vehicle towing:

• What is the towing capacity of the towingvehicle? Be sure you read the tow vehiclemanufacturer’s recommendations.

• How far will you tow? Some vehicles haverestrictions on how far and how long theycan tow.

• Do you have the proper towing equipment?See your dealer or trailering professionalfor additional advice and equipmentrecommendations.

• Is your vehicle ready to be towed? Just asyou would prepare your vehicle for a longtrip, you will want to make sure your vehicle isprepared to be towed. See Before Leavingon a Long Trip on page 298.

Dinghy Towing

Notice: If you tow your vehicle with allfour wheels on the ground, the drivetraincomponents could be damaged. The repairswould not be covered by your warranty.Do not tow your vehicle with all four wheelson the ground.

Your vehicle was not designed to be towed withall four wheels on the ground. If your vehicle mustbe towed, you should use a dolly. See “DollyTowing” that follows for more information.

Dolly Towing

Your vehicle can be towed using a dolly. To towyour vehicle using a dolly, follow these steps:

1. Put the front wheels on the dolly.

2. Put the vehicle in PARK (P).

3. Set the parking brake and then remove the key.

4. Clamp the steering wheel in a straight-aheadposition.

5. Release the parking brake.

Towing a Trailer

{CAUTION:

If you do not use the correct equipmentand drive properly, you can lose controlwhen you pull a trailer. For example, if thetrailer is too heavy, the brakes may notwork well — or even at all. You and yourpassengers could be seriously injured.You may also damage your vehicle; theresulting repairs would not be covered byyour warranty. Pull a trailer only if youhave followed all the steps in this section.Ask your dealer for advice andinformation about towing a trailer withyour vehicle.

Your vehicle can tow a trailer if it is equipped withthe proper trailer towing equipment. To identify thetrailering capacity of your vehicle, you should readthe information in “Weight of the Trailer” thatappears later in this section. Trailering is differentthan just driving your vehicle by itself. Traileringmeans changes in handling, acceleration, braking,durability and fuel economy. Successful, safetrailering takes correct equipment, and it has to beused properly.

That is the reason for this part. In it are manytime-tested, important trailering tips and safetyrules. Many of these are important for your safetyand that of your passengers. So please readthis section carefully before you pull a trailer.

Load-pulling components such as the engine,transaxle, wheel assemblies and tires are forced towork harder against the drag of the added weight.The engine is required to operate at relativelyhigher speeds and under greater loads, generatingextra heat. Also, the trailer adds considerably towind resistance, increasing the pullingrequirements.

315

Page 316: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

If You Do Decide To Pull A TrailerIf you do, here are some important points:

• There are many different laws, including speedlimit restrictions, having to do with trailering.Make sure your rig will be legal, not only whereyou live but also where you will be driving.A good source for this information can be stateor provincial police.

• Consider using a sway control. You can ask ahitch dealer about sway controls.

• Do not tow a trailer at all during the first1,000 miles (1 600 km) your new vehicleis driven. Your engine, axle or other partscould be damaged.

• Then, during the first 500 miles (800 km) thatyou tow a trailer, do not drive over 50 mph(80 km/h) and do not make starts at fullthrottle. This helps your engine and other partsof your vehicle wear in at the heavier loads.

• Obey speed limit restrictions when towing atrailer. Do not drive faster than the maximumposted speed for trailers, or no more than55 mph (90 km/h), to save wear on yourvehicle’s parts.

Three important considerations have to dowith weight:

• The weight of the trailer.

• The weight of the trailer tongue.

• The total weight on your vehicle’s tires.

Weight of the TrailerHow heavy can a trailer safely be?

It should never weigh more than 1,000 lbs(450 kg). But even that can be too heavy.

It depends on how you plan to use your rig.For example, speed, altitude, road grades, outsidetemperature and how much your vehicle is usedto pull a trailer are all important. It can also dependon any special equipment that you have on yourvehicle, and the amount of tongue weight thevehicle can carry. See “Weight of the TrailerTongue” later in this section for more information.

Maximum trailer weight is calculated assumingonly the driver is in the tow vehicle and it has allthe required trailering equipment. The weightof additional optional equipment, passengers andcargo in the tow vehicle must be subtractedform the maximum trailer weight.

Weight of the Trailer TongueThe tongue load (A) of any trailer is an importantweight to measure because it affects the totalor gross weight of your vehicle. The Gross VehicleWeight (GVW) includes the curb weight of thevehicle, any cargo you may carry in it, andthe people who will be riding in the vehicle. If youhave a lot of options, equipment, passengers,or cargo in your vehicle, it will reduce the tongueweight your vehicle can carry, which will alsoreduce the trailer weight your vehicle can tow.

And if you tow a trailer, you must add the tongueload to the GVW because your vehicle will becarrying that weight, too. See Loading YourVehicle on page 307 for more information aboutyour vehicle’s maximum load capacity.

If you are using a weight-carrying hitch, the trailertongue (A) should weigh 10 to 15 percent ofthe total loaded trailer weight (B).

After you have loaded your trailer, weigh the trailerand then the tongue, separately, to see if theweights are proper. If they are not, you may beable to get them right simply by moving someitems around in the trailer.

317

Page 318: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Total Weight on Your Vehicle’s TiresBe sure your vehicle’s tires are inflated to the upperlimit for cold tires. You will find these numbers onthe Tire-Loading Information label. See LoadingYour Vehicle on page 307. Then be sure you do notgo over the GVW limit for your vehicle, including theweight of the trailer tongue.

HitchesIt is important to have the correct hitch equipment.Crosswinds, large trucks going by and roughroads are a few reasons why you will need theright hitch. Here are some rules to follow:

• The rear bumper on your vehicle is notintended for hitches. Do not attach rentalhitches or other bumper-type hitches to it.Use only a frame-mounted hitch that does notattach to the bumper.

• Will you have to make any holes in the bodyof your vehicle when you install a trailerhitch? If you do, then be sure to seal the holeslater when you remove the hitch. If you donot seal them, deadly carbon monoxide (CO)from your exhaust can get into your vehicle.See Engine Exhaust on page 127. Dirtand water can also enter the vehicle.

Safety ChainsYou should always attach chains between yourvehicle and your trailer. Cross the safetychains under the tongue of the trailer so that thetongue will not drop to the road if it becomesseparated from the hitch. Instructions about safetychains may be provided by the hitch manufactureror by the trailer manufacturer. Follow themanufacturer’s recommendation for attachingsafety chains and do not attach them to thebumper. Always leave just enough slack so youcan turn with your rig. And, never allow safetychains to drag on the ground.

Trailer BrakesDoes your trailer have its own brakes? Be sure toread and follow the instructions for the trailerbrakes so you will be able to install, adjust andmaintain them properly.

Because you have anti-lock brakes, do not try totap into your vehicle’s brake system. If you do,both brake systems will not work well, or at all.

Trailer Wiring HarnessAll of the electrical circuits required for your trailerlighting system can be accessed at the driver’sside rear lamp connector. This connector is locatedunder the carpet on the rear corner of the trunkcompartment.

Driving with a TrailerTowing a trailer requires a certain amount ofexperience. Before setting out for the open road,you will want to get to know your rig. Acquaintyourself with the feel of handling and braking withthe added weight of the trailer. And alwayskeep in mind that the vehicle you are driving isnow a good deal longer and not nearly asresponsive as your vehicle is by itself.

Before you start, check all trailer hitch parts andattachments, safety chains, electrical connector,lamps, tires and mirror adjustment. If the trailerhas electric brakes, start your vehicle andtrailer moving and then apply the trailer brakecontroller by hand to be sure the brakes areworking. This lets you check your electricalconnection at the same time.

During your trip, check occasionally to be surethat the load is secure, and that the lamps and anytrailer brakes are still working.

Following DistanceStay at least twice as far behind the vehicle aheadas you would when driving your vehicle withouta trailer. This can help you avoid situationsthat require heavy braking and sudden turns.

PassingYou will need more passing distance up aheadwhen you are towing a trailer. And, becausethe vehicle is a good deal longer, you will need togo much farther beyond the passed vehiclebefore you can return to your lane.

319

Page 320: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Backing UpHold the bottom of the steering wheel withone hand. Then, to move the trailer to the left,just move that hand to the left. To move thetrailer to the right, move your hand to the right.Always back up slowly and, if possible, havesomeone guide you.

Making Turns

Notice: Making very sharp turns whiletrailering could cause the trailer to come incontact with the vehicle. Your vehicle could bedamaged. Avoid making very sharp turnswhile trailering.

When you are turning with a trailer, make widerturns than normal. Do this so your trailer willnot strike soft shoulders, curbs, road signs, treesor other objects. Avoid jerky or suddenmaneuvers. Signal well in advance.

Turn Signals When Towing a TrailerWhen you tow a trailer, your vehicle may need adifferent turn signal flasher and/or extra wiring.Check with your dealer. The arrows on yourinstrument panel will flash whenever you signal aturn or lane change. Properly hooked up, thetrailer lamps will also flash, telling other drivers youare about to turn, change lanes or stop.

When towing a trailer, the arrows on yourinstrument panel will flash for turns even if the bulbson the trailer are burned out. Thus, you may thinkdrivers behind you are seeing your signal whenthey are not. It is important to check occasionally tobe sure the trailer bulbs are still working.

Your vehicle has bulb warning lights. When youplug a trailer lighting system into your vehicle’slighting system, its bulb warning lights may notlet you know if one of your lamps goes out.So, when you have a trailer lighting systemplugged in, be sure to check your vehicle andtrailer lamps from time to time to be sure they areall working. Once you disconnect the trailerlamps, the bulb warning lights again can tell you ifone of your vehicle lamps is out.

Driving On GradesReduce speed and shift to a lower gear beforeyou start down a long or steep downgrade. If youdo not shift down, you might have to use yourbrakes so much that they would get hot andno longer work well.

On a long uphill grade, shift down to THIRD (3)and reduce your speed to around 45 mph(70 km/h) to reduce the possibility of engine andtransaxle overheating.

Parking on Hills

{CAUTION:

You really should not park yourvehicle, with a trailer attached, on a hill.If something goes wrong, your rig couldstart to move. People can be injured, andboth your vehicle and the trailer can bedamaged.

But if you ever have to park your rig on a hill, hereis how to do it:

1. Apply your regular brakes, but do not shift intoPARK (P) yet.

2. Have someone place chocks under the trailerwheels.

3. When the wheel chocks are in place, releasethe regular brakes until the chocks absorbthe load.

4. Reapply the regular brakes. Then apply yourparking brake, and then shift to PARK (P).

5. Release the regular brakes.

When You Are Ready to Leave AfterParking on a Hill1. Apply your regular brakes and hold the pedal

down while you:

• Start your engine.

• Shift into a gear.

• Release the parking brake.

2. Let up on the brake pedal.

3. Drive slowly until the trailer is clear ofthe chocks.

4. Stop and have someone pick up and storethe chocks.

Maintenance When Trailer TowingYour vehicle will need service more often whenyou’re pulling a trailer. See the MaintenanceSchedule for more on this. Things that areespecially important in trailer operation areautomatic transaxle fluid (don’t overfill), engine oil,drive belt, cooling system and brake system.Each of these is covered in this manual, and theIndex will help you find them quickly. If you’retrailering, it’s a good idea to review this informationbefore you start your trip.

Check periodically to see that all hitch nuts andbolts are tight.

Engine Cooling When Trailer TowingYour cooling system may temporarily overheatduring severe operating conditions. See EngineOverheating on page 351.

Adding Equipment to the Outside ofYour VehicleThings you might add to the outside of yourvehicle can affect the airflow around it. This maycause wind noise and affect windshield washerperformance. Check with your dealer beforeadding equipment to the outside of your vehicle.

FuelUse of the recommended fuel is an important partof the proper maintenance of your vehicle. Tohelp keep your engine clean and maintain optimumvehicle performance, GM recommends the useof gasoline advertised as TOP TIER DetergentGasoline.

The 8th digit of your Vehicle Identification Number(VIN) shows the code letter or number thatidentifies your engine. You will find the VIN at thetop left of the instrument panel. See VehicleIdentification Number (VIN) on page 427.

Gasoline OctaneIf your vehicle has the 3.8L V6 engine (VINCode 2), use regular unleaded gasoline with aposted octane rating of 87 or higher. If the octanerating is less than 87, you may notice an audibleknocking noise when you drive, commonly referredto as spark knock. If this occurs, use a gasolinerated at 87 octane or higher as soon as possible.If you are using gasoline rated at 87 octane orhigher and you hear heavy knocking, your engineneeds service.

If your vehicle has the 4.6L V8 engine (VINCode Y), use premium unleaded gasoline with aposted octane rating of 91 or higher. You may alsouse regular unleaded gasoline rated at 87 octaneor higher, but your vehicle’s acceleration maybe slightly reduced, and you may notice a slightaudible knocking noise, commonly referred toas spark knock. If the octane is less than 87, youmay notice a heavy knocking noise when youdrive. If this occurs, use a gasoline rated at87 octane or higher as soon as possible.Otherwise, you might damage your engine. If youare using gasoline rated at 87 octane or higherand you hear heavy knocking, your engine needsservice.

Page 328: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Gasoline SpecificationsAt a minimum, gasoline should meet ASTMspecification D 4814 in the United States orCAN/CGSB-3.5 in Canada. Some gasolines maycontain an octane-enhancing additive calledmethylcyclopentadienyl manganese tricarbonyl(MMT). General Motors recommends against theuse of gasolines containing MMT. See Additiveson page 328 for additional information.

California FuelIf your vehicle is certified to meet CaliforniaEmissions Standards, it is designed to operate onfuels that meet California specifications. Seethe underhood emission control label. If this fuel isnot available in states adopting Californiaemissions standards, your vehicle will operatesatisfactorily on fuels meeting federalspecifications, but emission control systemperformance may be affected. The malfunctionindicator lamp may turn on and your vehicle mayfail a smog-check test. See Malfunction IndicatorLamp on page 206. If this occurs, return toyour authorized GM dealer for diagnosis.

If it is determined that the condition is caused bythe type of fuel used, repairs may not becovered by your warranty.

AdditivesTo provide cleaner air, all gasolines in the UnitedStates are now required to contain additivesthat will help prevent engine and fuel systemdeposits from forming, allowing your emissioncontrol system to work properly. In most cases,you should not have to add anything to your fuel.However, some gasolines contain only theminimum amount of additive required to meetU.S. Environmental Protection Agency regulations.To help keep fuel injectors and intake valvesclean, or if your vehicle experiences problems dueto dirty injectors or valves, look for gasoline thatis advertised as TOP TIER Detergent Gasoline.Also, your dealer has additives that will helpcorrect and prevent most deposit-related problems.

Gasolines containing oxygenates, such as ethersand ethanol, and reformulated gasolines maybe available in your area. General Motorsrecommends that you use these gasolines if theycomply with the specifications described earlier.However, E85 (85% ethanol) and other fuelscontaining more than 10% ethanol must not beused in vehicles that were not designed forthose fuels.

Notice: Your vehicle was not designed forfuel that contains methanol. Do not usefuel containing methanol. It can corrode metalparts in your fuel system and also damagethe plastic and rubber parts. That damagewould not be covered under your warranty.

Some gasolines that are not reformulated for lowemissions may contain an octane-enhancingadditive called methylcyclopentadienyl manganesetricarbonyl (MMT); ask the attendant where youbuy gasoline whether the fuel contains MMT.

General Motors recommends against the use ofsuch gasolines. Fuels containing MMT can reducethe life of spark plugs and the performance ofthe emission control system may be affected. Themalfunction indicator lamp may turn on. If thisoccurs, return to your dealer for service.

Fuels in Foreign CountriesIf you plan on driving in another country outsidethe United States or Canada, the proper fuel maybe hard to find. Never use leaded gasoline orany other fuel not recommended in the previoustext on fuel. Costly repairs caused by use ofimproper fuel would not be covered by yourwarranty.

To check the fuel availability, ask an auto club, orcontact a major oil company that does businessin the country where you will be driving.

Engine OilIf the OIL LEVEL LOW ADD OIL messageappears in the Driver Information Center (DIC), itmeans you need to check the engine oil levelright away. For more information, see DICWarnings and Messages on page 221. You shouldcheck the engine oil level regularly; this is anadded reminder.

Checking Engine OilIt is a good idea to check the engine oil every timeyou get fuel. In order to get an accurate reading,the oil must be warm and the vehicle must beon level ground.

The engine oil dipstick handle is a yellow loop.See Engine Compartment Overview on page 334for the location of the engine oil dipstick.

1. Turn off the engine and give the oil severalminutes to drain back into the oil pan. If youdo not do this, the oil dipstick might notshow the actual level.

2. Pull out the dipstick and clean it with a papertowel or cloth, then push it back in all theway. Remove it again, keeping the tip down,and check the level.

337

Page 338: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

When to Add Engine Oil If the oil is below the cross-hatched area at the tipof the dipstick, you will need to add at least onequart/liter of oil. But you must use the rightkind. This section explains what kind of oil to use.For engine oil crankcase capacity, see Capacitiesand Specifications on page 436.

Notice: Do not add too much oil. If the enginehas so much oil that the oil level gets above thecross-hatched area that shows the properoperating range, the engine could be damaged.

See EngineCompartment Overviewon page 334 for thelocation of the engine oilfill cap.

Be sure to add enough oil to put the levelsomewhere in the proper operating range in thecross-hatched area. Push the dipstick all theway back in when you are through.

What Kind of Engine Oil to Use

Look for two things:

• GM6094MYour vehicle’s engine requires oil meeting GMStandard GM6094M. You should look forand use only an oil that meets GM StandardGM6094M.

• SAE 5W-30As shown in the viscosity chart, SAE 5W-30 isbest for your vehicle.

These numbers on an oil container show itsviscosity, or thickness. Do not use otherviscosity oils such as SAE 20W-50.

Oils meeting theserequirements shouldalso have the starburstsymbol on thecontainer. This symbolindicates that the oilhas been certified by theAmerican PetroleumInstitute (API).

You should look for this information on the oilcontainer, and use only those oils that are identifiedas meeting GM Standard GM6094M and have thestarburst symbol on the front of the oil container.Notice: Use only engine oil identified asmeeting GM Standard GM6094M and showingthe American Petroleum Institute CertifiedFor Gasoline Engines starburst symbol. Failureto use the recommended oil can result inengine damage not covered by your warranty.GM Goodwrench® oil meets all the requirementsfor your vehicle.

339

Page 340: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

If you are in an area of extreme cold, where thetemperature falls below −20°F (−29°C), it isrecommended that you use either an SAE 5W-30synthetic oil or an SAE 0W-30 oil. Both willprovide easier cold starting and better protectionfor the engine at extremely low temperatures.

Engine Oil AdditivesDo not add anything to the oil. The recommendedoils with the starburst symbol that meet GMStandard GM6094M are all you will need for goodperformance and engine protection.

Engine Oil Life System

When to Change Engine OilYour vehicle has a computer system that lets youknow when to change the engine oil and filter.This is based on engine revolutions and enginetemperature, and not on mileage. Based on drivingconditions, the mileage at which an oil changewill be indicated can vary considerably. For the oillife system to work properly, you must reset thesystem every time the oil is changed.

When the system has calculated that oil life hasbeen diminished, it will indicate that an oil changeis necessary. A CHANGE ENGINE OIL SOONmessage will come on. See DIC Warningsand Messages on page 221. Change your oil assoon as possible within the next 600 miles(1 000 km). It is possible that, if you are drivingunder the best conditions, the oil life system maynot indicate that an oil change is necessary forover a year. However, your engine oil andfilter must be changed at least once a year and atthis time the system must be reset. Your dealerhas GM-trained service people who will performthis work using genuine GM parts and resetthe system. It is also important to check your oilregularly and keep it at the proper level.

If the system is ever reset accidentally, you mustchange your oil at 3,000 miles (5 000 km)since your last oil change. Remember to reset theoil life system whenever the oil is changed.

340

Page 341: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

How to Reset the Engine Oil LifeSystemThe Engine Oil Life System calculates when tochange your engine oil and filter based on vehicleuse. Anytime your oil is changed, reset thesystem so it can calculate when the next oilchange is required. If a situation occurs where youchange your oil prior to a CHANGE ENGINEOIL SOON message being turned on, reset thesystem.

Always reset the engine oil life to 100% afterevery oil change. It will not reset itself. To resetthe Engine Oil Life System, do the following:

1. Display the OIL LIFE REMAINING on the DIC.

2. Press and hold the SET/RESET button onthe DIC for more than five seconds. The oillife will change to 100%.

If the CHANGE ENGINE OIL SOON messagecomes back on when you start your vehicle, theEngine Oil Life System has not reset. Repeatthe procedure.

What to Do with Used OilUsed engine oil contains certain elements thatmay be unhealthy for your skin and couldeven cause cancer. Do not let used oil stay onyour skin for very long. Clean your skin and nailswith soap and water, or a good hand cleaner.Wash or properly dispose of clothing or ragscontaining used engine oil. See the manufacturer’swarnings about the use and disposal of oilproducts.

Used oil can be a threat to the environment. If youchange your own oil, be sure to drain all the oil fromthe filter before disposal. Never dispose of oil byputting it in the trash, pouring it on the ground, intosewers, or into streams or bodies of water. Instead,recycle it by taking it to a place that collects usedoil. If you have a problem properly disposing ofused oil, ask your dealer, a service station, or alocal recycling center for help.

Engine Air Cleaner/FilterSee Engine Compartment Overview on page 334for the location of the engine air cleaner/filter.

When to Inspect the Engine AirCleaner/FilterInspect the air cleaner/filter at the Maintenance IIintervals and replace it at the first oil changeafter each 50,000 mile (83 000 km) interval. SeeScheduled Maintenance on page 442 for moreinformation. If you are driving in dusty/dirtyconditions, inspect the filter at each engine oilchange.

How to Inspect the Engine AirCleaner/FilterTo inspect the air cleaner/filter, remove the filterfrom the vehicle and lightly shake the filter torelease loose dust and dirt. If the filter remainscaked with dirt, a new filter is required.

To inspect or replace the filter, do the following:

1. Loosen and remove the two screws on thetop of the engine air cleaner/filter cover.

2. Lift up the outboard side of the cover at anangle while pulling toward you. This isnecessary due to the two hinges located onthe inboard side of the cover.

3. Remove the engine air cleaner/filter elementand any loose debris that may be found in theair cleaner base.

4. Inspect or replace the air filter element.

342

Page 343: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Follow these steps to reinstall the cover to theengine air cleaner/filter housing:

1. Align the two hinges located on the inboardside of the cover.

3. Tighten the two screws on the top of theengine air cleaner/filter housing cover.

{CAUTION:

Operating the engine with the air cleaner/filter off can cause you or others to beburned. The air cleaner not only cleans theair; it helps to stop flames if the enginebackfires. If it is not there and the enginebackfires, you could be burned. Do notdrive with it off, and be careful working onthe engine with the air cleaner/filter off.

Notice: If the air cleaner/filter is off, a backfirecan cause a damaging engine fire. And, dirtcan easily get into your engine, which willdamage it. Always have the air cleaner/filter inplace when you are driving.

Automatic Transaxle Fluid

When to Check and Change AutomaticTransaxle FluidA good time to check your automatic transaxlefluid level is when the engine oil is changed.

Change the fluid and filter at the intervals listed inScheduled Maintenance on page 442, and besure to use the transaxle fluid listed inRecommended Fluids and Lubricants on page 452.

343

How to Check Automatic TransaxleFluid (3.8L Engine)Because this operation can be a little difficult, youmay choose to have this done at the dealershipservice department.

If you do it yourself, be sure to follow all theinstructions here, or you could get a false readingon the dipstick.

Notice: Too much or too little fluid candamage the transaxle. Too much can mean thatsome of the fluid could come out and fall on hotengine or exhaust system parts, starting a fire.Too little fluid could cause the transaxle tooverheat. Be sure to get an accurate reading ifyou check the transaxle fluid.

Wait at least 30 minutes before checking thetransaxle fluid level if you have been driving:

• When outside temperatures are above90°F (32°C).

• At high speed for quite a while.

• In heavy traffic — especially in hot weather.

• While pulling a trailer.

To get the right reading, the fluid should be atnormal operating temperature, which is180°F to 200°F (82°C to 93°C).

Get the vehicle warmed up by driving about15 miles (24 km) when outside temperatures areabove 50°F (10°C). If it is colder than 50°F (10°C),you may have to drive longer.

Checking the Fluid LevelPrepare your vehicle as follows:

1. Park your vehicle on a level place. Keep theengine running.

2. With the parking brake applied, place the shiftlever in PARK (P).

3. With your foot on the brake pedal, move theshift lever through each gear range, pausingfor about three seconds in each range.Then, position the shift lever in PARK (P).

4. Let the engine run at idle for three tofive minutes.

How to Add Automatic Transaxle FluidRefer to the Maintenance Schedule to determinewhat kind of transaxle fluid to use. SeeRecommended Fluids and Lubricants on page 452.If the fluid level is low, add only enough of theproper fluid to bring the level into thecross-hatched area on the dipstick.

1. Pull out the dipstick.

2. Using a long-neck funnel, add enough fluid atthe dipstick hole to bring it to the proper level.It does not take much fluid, generally lessthan one pint (0.5 L). Do not overfill.

Notice: Use of the incorrect automatictransaxle fluid may damage your vehicle, andthe damages may not be covered by yourwarranty. Always use the automatic transaxlefluid listed in Recommended Fluids andLubricants on page 452.

3. After adding fluid, recheck the fluid level asdescribed under “How to Check AutomaticTransaxle Fluid,” earlier in this section.

4. When the correct fluid level is obtained, pushthe dipstick back in all the way.

How to Check Automatic TransaxleFluid (4.6L Engine)For the 4.6L V8 engine, it is not necessary to checkthe transaxle fluid level. A transaxle fluid leak is theonly reason for fluid loss. If a leak occurs, take yourvehicle to the dealership service department andhave it repaired as soon as possible.

Engine CoolantThe cooling system in your vehicle is filled withDEX-COOL® engine coolant. This coolant isdesigned to remain in your vehicle for five years or150,000 miles (240 000 km), whichever occursfirst, if you add only DEX-COOL® extendedlife coolant.

The following explains your cooling system andhow to add coolant when it is low. If you havea problem with engine overheating, see EngineOverheating on page 351.

A 50/50 mixture of clean, drinkable water andDEX-COOL® coolant will:

• Give freezing protection down to−34°F (−37°C).

• Give boiling protection up to 265°F (129°C).

• Protect against rust and corrosion.

• Help keep the proper engine temperature.

• Let the warning lights and gages work asthey should.

Notice: Using coolant other than DEX-COOL®

may cause premature engine, heater core,or radiator corrosion. In addition, the enginecoolant may require changing sooner, atthe first maintenance service after each30,000 miles (50 000 km) or 24 months,whichever occurs first. Any repairs would notbe covered by your warranty. Always useDEX-COOL® (silicate-free) coolant in yourvehicle.

What to UseUse a mixture of one-half clean, drinkable waterand one-half DEX-COOL® coolant which willnot damage aluminum parts. If you use this coolantmixture, you do not need to add anything else.

{CAUTION:

Adding only plain water to your coolingsystem can be dangerous. Plain water, orsome other liquid such as alcohol, canboil before the proper coolant mixture will.Your vehicle’s coolant warning system isset for the proper coolant mixture. Withplain water or the wrong mixture, yourengine could get too hot but you wouldnot get the overheat warning. Your enginecould catch fire and you or others couldbe burned. Use a 50/50 mixture of clean,drinkable water and DEX-COOL® coolant.

Notice: If you use an improper coolantmixture, your engine could overheat and bebadly damaged. The repair cost would not becovered by your warranty. Too much waterin the mixture can freeze and crack the engine,radiator, heater core, and other parts.

If you have to add coolant more than four times ayear, have your dealer check your coolingsystem.

Notice: If you use extra inhibitors and/oradditives in your vehicle’s cooling system, youcould damage your vehicle. Use only theproper mixture of the engine coolant listed inthis manual for the cooling system. SeeRecommended Fluids and Lubricants onpage 452 for more information.

This symbol is locatedon the cap of the enginecoolant recovery tank.

The engine coolant recovery tank is located in theengine compartment on the passenger’s side ofthe vehicle. See Engine Compartment Overview onpage 334 for more information on location.

The vehicle must be on a level surface. Whenyour engine is cold, the coolant level should be atFULL COLD or a little higher. When your engineis warm, the level should raise.

Adding CoolantIf you need more coolant, add the properDEX-COOL® coolant mixture at the coolantrecovery tank, but be careful not to spill it.

{CAUTION:

Turning the radiator pressure cap when theengine and radiator are hot can allow steamand scalding liquids to blow out and burnyou badly. With the coolant recovery tank,you will almost never have to add coolantat the radiator. Never turn the radiatorpressure cap — even a little — whenthe engine and radiator are hot.

{CAUTION:

You can be burned if you spill coolant onhot engine parts. Coolant contains ethyleneglycol, and it will burn if the engine partsare hot enough. Do not spill coolant on ahot engine.

How to Check Power Steering FluidTo check the power steering fluid, do the following:

1. Turn the key off and let the enginecompartment cool down.

2. Wipe the cap and the top of the reservoirclean.

3. Unscrew the cap and wipe the dipstick with aclean rag.

4. Replace the cap and completely tighten it.

5. Remove the cap again and look at thefluid level on the dipstick.

The level should be at the FULL COLD mark. Ifnecessary, add only enough fluid to bring the levelup to the mark.

What to UseTo determine what kind of fluid to use, seeRecommended Fluids and Lubricants on page 452.Always use the proper fluid. Failure to use theproper fluid can cause leaks and damage hosesand seals.

Windshield Washer Fluid

What to UseWhen you need windshield washer fluid, be sureto read the manufacturer’s instructions beforeuse. If you will be operating your vehicle in an areawhere the temperature may fall below freezing,use a fluid that has sufficient protection againstfreezing.

Adding Washer Fluid

Open the cap with thewasher symbol on it.Add washer fluiduntil the tank is full. SeeEngine CompartmentOverview on page 334for reservoir location.

Notice:• When using concentrated washer fluid,

follow the manufacturer’s instructionsfor adding water.

• Do not mix water with ready-to-use washerfluid. Water can cause the solution tofreeze and damage your washer fluid tankand other parts of the washer system.Also, water does not clean as wellas washer fluid.

• Fill your washer fluid tank onlythree-quarters full when it is very cold.This allows for expansion if freezingoccurs, which could damage the tank if itis completely full.

• Do not use engine coolant (antifreeze) inyour windshield washer. It can damageyour washer system and paint.

Brakes

Brake Fluid

Your brake mastercylinder reservoir isfilled with DOT-3 brakefluid. See EngineCompartment Overviewon page 334 for thelocation of the reservoir.

There are only two reasons why the brake fluidlevel in the reservoir might go down. The firstis that the brake fluid goes down to an acceptablelevel during normal brake lining wear. Whennew linings are put in, the fluid level goes backup. The other reason is that fluid is leaking out ofthe brake system. If it is, you should have yourbrake system fixed, since a leak means thatsooner or later your brakes will not work well, orwill not work at all.

So, it is not a good idea to top off your brake fluid.Adding brake fluid will not correct a leak. If youadd fluid when your linings are worn, then you willhave too much fluid when you get new brakelinings. You should add or remove brake fluid, asnecessary, only when work is done on thebrake hydraulic system.

{CAUTION:

If your vehicle has too much brake fluid, itcan spill on the engine. The fluid will burnif the engine is hot enough. You or otherscould be burned, and your vehicle couldbe damaged. Add brake fluid only whenwork is done on the brake hydraulicsystem.

When your brake fluid falls to a low level, yourbrake warning light will come on. See BrakeSystem Warning Light on page 201.

367

Page 368: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

What to AddWhen you do need brake fluid, use only DOT-3brake fluid. Use new brake fluid from a sealedcontainer only. See Recommended Fluidsand Lubricants on page 452.

Always clean the brake fluid reservoir cap and thearea around the cap before removing it. Thiswill help keep dirt from entering the reservoir.

{CAUTION:

With the wrong kind of fluid in the brakesystem, the brakes may not work well, orthey may not even work at all. This couldcause a crash. Always use the properbrake fluid.

Notice:• Using the wrong fluid can badly damage

brake system parts. For example, just afew drops of mineral-based oil, suchas engine oil, in the brake system candamage brake system parts so badly thatthey will have to be replaced. Do notlet someone put in the wrong kind of fluid.

• If you spill brake fluid on your vehicle’spainted surfaces, the paint finish canbe damaged. Be careful not to spill brakefluid on your vehicle. If you do, wash itoff immediately. See Washing Your Vehicleon page 422.

Brake WearYour vehicle has four-wheel disc brakes.

Disc brake pads have built-in wear indicators thatmake a high-pitched warning sound when thebrake pads are worn and new pads are needed.The sound may come and go or be heard allthe time your vehicle is moving, except when youare pushing on the brake pedal firmly.

{CAUTION:

The brake wear warning sound means thatsoon the brakes will not work well. Thatcould lead to an accident. When you hearthe brake wear warning sound, have yourvehicle serviced.

Notice: Continuing to drive with worn-outbrake pads could result in costly brake repair.

Some driving conditions or climates may causea brake squeal when the brakes are first applied orlightly applied. This does not mean something iswrong with your brakes.

Properly torqued wheel nuts are necessary to helpprevent brake pulsation. When tires are rotated,inspect brake pads for wear and evenly tightenwheel nuts in the proper sequence to GM torquespecifications.

Brake linings should always be replaced ascomplete axle sets.

Brake Pedal TravelSee your dealer if the brake pedal does not returnto normal height, or if there is a rapid increase inpedal travel. This could be a sign of brake trouble.

Brake AdjustmentEvery time you apply the brakes, with or withoutthe vehicle moving, your brakes adjust for wear.

Replacing Brake System PartsThe braking system on a vehicle is complex. Itsmany parts have to be of top quality and work welltogether if the vehicle is to have really goodbraking. Your vehicle was designed and testedwith top-quality GM brake parts. When you replaceparts of your braking system — for example,when your brake linings wear down and you neednew ones put in — be sure you get newapproved GM replacement parts. If you do not,your brakes may no longer work properly.For example, if someone puts in brake linings thatare wrong for your vehicle, the balance betweenyour front and rear brakes can change — forthe worse. The braking performance you havecome to expect can change in many other waysif someone puts in the wrong replacementbrake parts.

BatteryYour vehicle has a maintenance free battery.When it is time for a new battery, get one that hasthe replacement number shown on the originalbattery’s label. We recommend an ACDelco®

replacement battery.Warning: Battery posts, terminals, and relatedaccessories contain lead and lead compounds,chemicals known to the State of Californiato cause cancer and reproductive harm. Washhands after handling.

{CAUTION:

Fans or other moving engine parts caninjure you badly. Keep your hands awayfrom moving parts once the engine isrunning.

5. Check that the jumper cables do not haveloose or missing insulation. If they do, youcould get a shock. The vehicles couldbe damaged too.Before you connect the cables, here are somebasic things you should know. Positive (+)will go to positive (+) or to a remotepositive (+) terminal if the vehicle has one.Negative (−) will go to a heavy, unpaintedmetal engine part or to a remote negative (−)terminal if the vehicle has one.Do not connect positive (+) to negative (−) oryou will get a short that would damagethe battery and maybe other parts too. And donot connect the negative (−) cable to thenegative (−) terminal on the dead batterybecause this can cause sparks.

6. Connect the red positive (+) cable to thepositive (+) terminal of the dead battery.Use a remote positive (+) terminal ifthe vehicle has one.

7. Do not let the other end touch metal. Connectit to the positive (+) terminal of the goodbattery. Use a remote positive (+) terminal ifthe vehicle has one.

8. Now connect the black negative (−) cable tothe negative (−) terminal of the good battery.Use a remote negative (−) terminal if thevehicle has one.Do not let the other end touch anything untilthe next step. The other end of thenegative (−) cable does not go to the deadbattery. It goes to a heavy, unpaintedmetal engine part or to a remote negative (−)terminal on the vehicle with the deadbattery.

9. Connect the other end of the negative (−) cableat least 18 inches (45 cm) away from the deadbattery, but not near engine parts that move.The electrical connection is just as good there,and the chance of sparks getting back to thebattery is much less.

10. Now start the vehicle with the good batteryand run the engine for a while.

11. Try to start the vehicle that had the deadbattery. If it will not start after a few tries, itprobably needs service.

Notice: If the jumper cables are connected orremoved in the wrong order, electrical shortingmay occur and damage the vehicle. The repairswould not be covered by your warranty. Alwaysconnect and remove the jumper cables in thecorrect order, making sure that the cables donot touch each other or other metal.

Headlamp AimingThe vehicle has a visual optical headlamp aimingsystem. The aim of the headlamps have beenpreset at the factory and should need no furtheradjustment.

However, if the vehicle is damaged in an accident,the aim of the headlamps may be affected andadjustment may be necessary.

If oncoming vehicles flash their high beams atyou, this may mean the vertical aim of yourheadlamps needs to be adjusted.

It is recommended that the vehicle is taken to yourdealer for service if the headlamps need to beadjusted. It is possible however, to re-aim theheadlamps as described in the following procedure.

The vehicle should be properly prepared asfollows:

• The vehicle should be placed so theheadlamps are 25 ft. (7.6 m) from a lightcolored wall.

• The vehicle must have all four tires on a levelsurface which is level all the way to the wall.

• The vehicle should be placed so it isperpendicular to the wall.

• The vehicle should not have any snow, ice ormud on it.

• The vehicle should be fully assembled and allother work stopped while headlamp aiming isbeing performed.

• The vehicle should be normally loaded with afull tank of fuel and one person or 160 lbs(75 kg) sitting on the driver’s seat.

• Tires should be properly inflated.

• The spare tire is in its proper location in thevehicle.

377

Inflation - Tire PressureTires need the correct amount of air pressure tooperate effectively.

Notice: Do not let anyone tell you thatunder-inflation or over-inflation is all right. It isnot. If your tires do not have enough air(under-inflation), you can get the following:• Too much flexing

• Too much heat

• Tire overloading

• Premature or irregular wear

• Poor handling

• Reduced fuel economy

If your tires have too much air (over-inflation),you can get the following:• Unusual wear

• Poor handling

• Rough ride

• Needless damage from road hazards

A Tire and Loading Information label is attached tothe vehicle’s center pillar (B-pillar). This labelshows your vehicle’s original equipment tires andthe correct inflation pressures for your tireswhen they are cold. The recommended cold tireinflation pressure, shown on the label, is theminimum amount of air pressure needed tosupport your vehicle’s maximum load carryingcapacity.

For additional information regarding how muchweight your vehicle can carry, and an example ofthe Tire and Loading Information label, seeLoading Your Vehicle on page 307. How you loadyour vehicle affects vehicle handling and ridecomfort. Never load your vehicle with more weightthan it was designed to carry.

When to CheckCheck your tires once a month or more. Do notforget to check the compact spare tire, it should beat 60 psi (420 kPa). For additional informationregarding the compact spare tire, see CompactSpare Tire on page 418.

How to CheckUse a good quality pocket-type gage to check tirepressure. You cannot tell if your tires areproperly inflated simply by looking at them. Radialtires may look properly inflated even when theyare under-inflated. Check the tire’s inflationpressure when the tires are cold. Cold means yourvehicle has been sitting for at least three hoursor driven no more than 1 mile (1.6 km).

Remove the valve cap from the tire valve stem.Press the tire gage firmly onto the valve toget a pressure measurement. If the cold tireinflation pressure matches the recommendedpressure on the Tire and Loading Informationlabel, no further adjustment is necessary. If theinflation pressure is low, add air until you reach therecommended amount.

If you overfill the tire, release air by pushing onthe metal stem in the center of the tire valve.Re-check the tire pressure with the tire gage.

Be sure to put the valve caps back on the valvestems. They help prevent leaks by keeping out dirtand moisture.

Tire Pressure Monitor SystemYour vehicle has a Tire Pressure Monitor System(TPMS). This system uses radio and sensortechnology to check tire pressure levels. TheTPMS sensors are mounted onto each tire andwheel assembly, except for the spare tire.The TPMS sensors monitor the air pressure inyour vehicle’s tires and transmit tire pressurereadings to a receiver located in the vehicle.

393

Page 394: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

The TPMS is designed to alert the driver, if a lowtire pressure condition exists. If your vehiclehas the Driver Information Center (DIC), the drivermay also check tire pressure levels using theDIC buttons located on the instrument panel.

When a low tire pressure condition is detected,the TPMS will illuminate the low tire pressurewarning symbol, located on the instrument panelcluster, and at the same time a message to checkthe pressure in a specific tire will also appear onthe DIC display. The low tire pressure warningsymbol on the instrument panel cluster andthe CHECK TIRE PRESSURE warning messageon the DIC display will appear at each ignitioncycle until the tires are inflated to the correctinflation pressure. For additional information anddetails about the DIC operation and displayssee DIC Controls and Displays on page 212 andDIC Warnings and Messages on page 221.

You may notice, during cooler weather conditions,that the tire pressure monitor light, located onthe instrument panel cluster, and the CHECK TIREPRESSURE message will appear when thevehicle is first started and the turn off as you start

to drive the vehicle. This could be an earlyindicator that the tire pressures are getting lowand need to be inflated to the proper pressure.

Each tire, including the spare (if provided), shouldbe checked monthly when cold and inflated tothe inflation pressure recommended by the vehiclemanufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tires ofa different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflationpressure for those tires.)

As an added safetyfeature, your vehiclehas been equipped witha tire pressuremonitoring system(TPMS) that illuminatesa low tire pressuretelltale when oneor more of your tires issignificantlyunder-inflated.

394

Page 395: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Accordingly, when the low tire pressure telltaleilluminates, you should stop and check your tiresas soon as possible, and inflate them to theproper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheat andcan lead to tire failure. Under-inflation alsoreduces fuel efficiency and tire tread life, and mayaffect the vehicle’s handling and stopping ability.

Please note that the TPMS is not a substitutefor proper tire maintenance, and it is the driver’sresponsibility to maintain correct tire pressure,even if under-inflation has not reached the level totrigger illumination of the TPMS low tire pressuretelltale.

Your vehicle has also been equipped with a TPMSmalfunction indicator to indicate when thesystem is not operating properly. The TPMSmalfunction indicator is combined with the low tirepressure telltale. When the system detects amalfunction, the telltale will flash for approximatelyone minute and then remain continuouslyilluminated. This sequence will continue uponsubsequent vehicle start-ups as long as themalfunction exists.

When the malfunction indicator is illuminated, thesystem may not be able to detect or signal lowtire pressure as intended. TPMS malfunctions mayoccur for a variety of reasons, including theinstallation of replacement or alternate tires orwheels on the vehicle that prevent the TPMS fromfunctioning properly. Always check the TPMSmalfunction telltale after replacing one or moretires or wheels on your vehicle to ensure that thereplacement or alternate tires and wheels allowthe TPMS to continue to function properly.

A tire and Loading Information label, attached toyour vehicle, shows the size of your vehicle’soriginal equipment tires and the correct inflationpressure for your vehicle’s tires when theyare cold. See Loading Your Vehicle on page 307,for an example of the tire information label andits location on your vehicle. Also see Inflation - TirePressure on page 392.

Your vehicle’s TPMS system can warn you about alow tire pressure condition but it does not replacenormal tire maintenance. See Tire Inspection andRotation on page 398 and Tires on page 385.

Notice: Do not use a tire sealant if yourvehicle has Tire Pressure Monitors. The liquidsealant can damage the tire pressure monitorsensors.

The TPMS will not function properly if one or moreof the TPMS sensors are missing or inoperable.If the system detects a missing or inoperablesensor, an error message SERVICE TIREMONITOR SYSTEM will be shown on the DICdisplay. If you have replaced a tire/wheel assemblywithout transferring the TPMS sensors, the errormessage will be displayed. Once you re-install theTPMS sensors, the error message should gooff. See your GM dealer for service if all TPMSsensors are installed and the error messagecomes on and stays on.

Resetting the TPMS SensorIdentification CodesEach TPMS sensor has a unique identificationcode. Any time you replace one or more ofthe TPMS sensors or rotate the vehicle’s tires, theidentification codes will need to be matched tothe new tire/wheel position. The sensors arematched, to the tire/wheel positions, in thefollowing order: driver’s side front tire, passenger’sside front tire, passenger’s side rear tire, anddriver’s side rear tire using a TPMS diagnostic tool.See your GM dealer for service.

The TPMS sensors may also be matched to eachtire/wheel position by increasing or decreasingthe tire’s air pressure. When increasing the tire’spressure, do not exceed the maximum inflationpressure indicated on the tire’s sidewall.

You will have two minutes to match each tire andwheel position. If it takes longer than two minutes tomatch any tire and wheel position, or more thanfive minutes to match all four tire and wheelpositions the matching process stops and you willneed to start over.

396

The TPMS matching process is outlined below:

1. Set the parking brake.

2. Turn the ignition switch to RUN with theengine off.

3. Using the DIC, press the vehicle informationbutton until the LEARN TIRE POSITIONSmessage displays.

4. Press the set/reset button to allow the systemto learn the tire positions. The horn will soundtwice to indicate the receiver is ready, andthe TIRE LEARNING ACTIVE messagewill display. The TPMS system is ready forthe sensor matching process to begin.

5. Start with the driver’s side front tire.

6. Remove the valve cap from the tire’s valvestem. Activate the TPMS sensor by increasingor decreasing the tire’s air pressure forfive seconds, or until a horn chirp sounds.The horn chirp, which may take up to30 seconds to sound, confirms that thesensor identification code has been matchedto the tire/wheel position. To decrease thetire’s air-pressure use the pointed end of thevalve cap, a pencil-style air pressure gage,or a key.

7. Proceed to the passenger’s side front tire, andrepeat the procedure in Step 6.

8. Proceed to the passenger’s side rear tire, andrepeat the procedure in Step 6.

9. Proceed to the driver’s side rear tire, andrepeat the procedure in Step 6.

10. After hearing the confirming horn chirp for thedriver’s side rear tire, the tire learning processends. Turn the ignition switch to OFF.

11. Set all four tires to the recommended airpressure level as indicated on the tire andloading information label.

12. Put the valve caps back on the valve stems.

The compact spare tire and wheel assemblydoes not have a TPMS sensor. If you replaceone of the road tires with the compact spare tire,the SERVICE TIRE MONITOR SYSTEMmessage will be displayed on the DIC displayscreen. This message should go off onceyou re-install the road tire containing theTPMS sensor.

When It Is Time for New Tires

One way to tell when itis time for new tires isto check the treadwearindicators, which willappear when your tireshave only 1/16 inch(1.6 mm) or less of treadremaining.

You need a new tire if any of the followingstatements are true:

• You can see the indicators at three or moreplaces around the tire.

• You can see cord or fabric showing throughthe tire’s rubber.

• The tread or sidewall is cracked, cut, orsnagged deep enough to show cord or fabric.

• The tire has a bump, bulge, or split.

• The tire has a puncture, cut, or other damagethat cannot be repaired well because of thesize or location of the damage.

Buying New TiresGM has developed and matched specific tires foryour vehicle. The original equipment tiresinstalled on your vehicle, when it was new, weredesigned to meet General Motors TirePerformance Criteria Specification (TPC spec)system rating. If you need replacement tires, GMstrongly recommends that you get tires withthe same TPC Spec rating. This way, your vehiclewill continue to have tires that are designed togive the same performance and vehicle safety,during normal use, as the original tires.

GM’s exclusive TPC Spec system considers overa dozen critical specifications that impact theoverall performance of your vehicle, includingbrake system performance, ride and handling,traction control, and tire pressure monitoringperformance. GM’s TPC Spec number is moldedonto the tire’s sidewall by the tire manufacturer.

400

Page 401: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

If the tires have an all-season tread design, theTPC spec number will be followed by an MSfor mud and snow. See Tire Sidewall Labeling onpage 386 for additional information.

{CAUTION:

Mixing tires could cause you to losecontrol while driving. If you mix tires ofdifferent sizes, brands, or types (radialand bias-belted tires), the vehicle may nothandle properly, and you could have acrash. Using tires of different sizes,brands, or types may also cause damageto your vehicle. Be sure to use the correctsize, brand, and type of tires on allwheels. It is all right to drive with yourcompact spare temporarily, as it wasdeveloped for use on your vehicle. SeeCompact Spare Tire on page 418.

{CAUTION:

If you use bias-ply tires on your vehicle,the wheel rim flanges could developcracks after many miles of driving. A tireand/or wheel could fail suddenly, causinga crash. Use only radial-ply tires with thewheels on your vehicle.

If you must replace your vehicle’s tires with thosethat do not have a TPC Spec number, makesure they are the same size, load range, speedrating, and construction type (radial andbias-belted tires) as your vehicle’s original tires.

Your vehicle’s original equipment tires are listed onthe Tire and Loading Information label. Thislabel is attached to the vehicle’s center pillar(B-pillar). See Loading Your Vehicle on page 307,for more information about the Tire and LoadingInformation label and its location on your vehicle.

Different Size Tires and WheelsIf you add wheels or tires that are a different sizethan your original equipment wheels and tires,this may affect the way your vehicle performs,including its braking, ride and handlingcharacteristics, stability, and resistance to rollover.Additionally, if your vehicle has electronicsystems such as, anti-lock brakes, traction control,and electronic stability control, the performanceof these systems can be affected.

{CAUTION:

If you add different sized wheels, yourvehicle may not provide an acceptablelevel of performance and safety if tires notrecommended for those wheels areselected. You may increase the chancethat you will crash and suffer seriousinjury. Only use GM specific wheel andtire systems developed for your vehicle,and have them properly installed by a GMcertified technician.

See Buying New Tires on page 400 andAccessories and Modifications on page 325 foradditional information.

Uniform Tire Quality GradingQuality grades can be found where applicable onthe tire sidewall between tread shoulder andmaximum section width. For example:

Treadwear 200 Traction AA Temperature AThe following information relates to the systemdeveloped by the United States National HighwayTraffic Safety Administration (NHTSA), whichgrades tires by treadwear, traction, andtemperature performance. This applies only tovehicles sold in the United States. The grades aremolded on the sidewalls of most passenger cartires. The Uniform Tire Quality Grading (UTQG)system does not apply to deep tread, winter-typesnow tires, space-saver, or temporary usespare tires, tires with nominal rim diameters of10 to 12 inches (25 to 30 cm), or to somelimited-production tires.

402

Page 403: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

While the tires available on General Motorspassenger cars and light trucks may vary withrespect to these grades, they must also conform tofederal safety requirements and additional GeneralMotors Tire Performance Criteria (TPC) standards.

TreadwearThe treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and a half (1.5) timesas well on the government course as a tiregraded 100. The relative performance of tiresdepends upon the actual conditions of their use,however, and may depart significantly fromthe norm due to variations in driving habits, servicepractices, and differences in road characteristicsand climate.

Traction – AA, A, B, CThe traction grades, from highest to lowest, are AA,A, B, and C. Those grades represent the tire’sability to stop on wet pavement as measured undercontrolled conditions on specified government testsurfaces of asphalt and concrete. A tire marked Cmay have poor traction performance.

Warning: The traction grade assigned to this tireis based on straight-ahead braking tractiontests, and does not include acceleration, cornering,hydroplaning, or peak traction characteristics.

Temperature – A, B, CThe temperature grades are A (the highest), B,and C, representing the tire’s resistance tothe generation of heat and its ability to dissipateheat when tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of the tireto degenerate and reduce tire life, and excessivetemperature can lead to sudden tire failure.The grade C corresponds to a level of performancewhich all passenger car tires must meet underthe Federal Motor Vehicle Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheelthan the minimum required by law.

Warning: The temperature grade for this tire isestablished for a tire that is properly inflatedand not overloaded. Excessive speed,under-inflation, or excessive loading, eitherseparately or in combination, can cause heatbuildup and possible tire failure.

Wheel Alignment and Tire BalanceThe tires and wheels on your vehicle were alignedand balanced carefully at the factory to give youthe longest tire life and best overall performance.Adjustments to wheel alignment and tirebalancing will not be necessary on a regular basis.However, if you notice unusual tire wear or yourvehicle pulling to one side or the other, thealignment may need to be checked. If you noticeyour vehicle vibrating when driving on a smoothroad, your tires and wheels may need to berebalanced. See your dealer for proper diagnosis.

Wheel ReplacementReplace any wheel that is bent, cracked, or badlyrusted or corroded. If wheel nuts keep comingloose, the wheel, wheel bolts, and wheelnuts should be replaced. If the wheel leaks air,replace it (except some aluminum wheels,which can sometimes be repaired). See yourdealer if any of these conditions exist.

Your dealer will know the kind of wheel you need.

Each new wheel should have the sameload-carrying capacity, diameter, width, offsetand be mounted the same way as the oneit replaces.

{CAUTION:

If your vehicle has P235/55R17, orP245/50R18 size tires, do not use tirechains. There is not enough clearance.

Tire chains used on a vehicle without theproper amount of clearance can causedamage to the brakes, suspension, orother vehicle parts. The area damaged bythe tire chains could cause you to losecontrol of your vehicle and you or othersmay be injured in a crash.

Use another type of traction device only ifits manufacturer recommends it for useon your vehicle and tire size combinationand road conditions.

CAUTION: (Continued)

CAUTION: (Continued)

Follow that manufacturer’s instructions.To help avoid damage to your vehicle,drive slowly, readjust or remove thedevice if it is contacting your vehicle, anddo not spin your vehicle’s wheels.

If you do find traction devices that will fit,install them on the front tires.

Notice: If your vehicle has P225/60R16 sizetires, use tire chains only where legal and onlywhen you must. Use only SAE Class S-typechains that are the proper size for yourtires. Install them on the front tires and tightenthem as tightly as possible with the endssecurely fastened. Drive slowly and follow thechain manufacturer’s instructions. If youcan hear the chains contacting your vehicle,stop and retighten them. If the contactcontinues, slow down until it stops.

If a Tire Goes FlatIt is unusual for a tire to blowout while you aredriving, especially if you maintain your vehicle’stires properly. If air goes out of a tire, it ismuch more likely to leak out slowly. But if youshould ever have a blowout, here are a few tipsabout what to expect and what to do:

If a front tire fails, the flat tire will create a dragthat pulls the vehicle toward that side. Take yourfoot off the accelerator pedal and grip thesteering wheel firmly. Steer to maintain laneposition, and then gently brake to a stop well outof the traffic lane.

A rear blowout, particularly on a curve, acts muchlike a skid and may require the same correctionyou would use in a skid. In any rear blowoutremove your foot from the accelerator pedal. Getthe vehicle under control by steering the wayyou want the vehicle to go. It may be very bumpyand noisy, but you can still steer. Gently braketo a stop, well off the road if possible.

{CAUTION:

Lifting a vehicle and getting under it to domaintenance or repairs is dangerouswithout the appropriate safety equipmentand training. The jack provided with yourvehicle is designed only for changing aflat tire. If it is used for anything else, youor others could be badly injured or killedif the vehicle slips off the jack. Use thejack provided with your vehicle only forchanging a flat tire.

Lighter colored interiors may require morefrequent cleaning. Use care because newspapersand garments that transfer color to your homefurnishings may also transfer color to yourvehicle’s interior.

When cleaning your vehicle’s interior, only usecleaners specifically designed for the surfacesbeing cleaned. Permanent damage may resultfrom using cleaners on surfaces for whichthey were not intended. Use glass cleaner only onglass. Remove any accidental over-spray fromother surfaces immediately. To prevent over-spray,apply cleaner directly to the cleaning cloth.

Notice: If you use abrasive cleaners whencleaning glass surfaces on your vehicle, youcould scratch the glass and/or cause damageto the integrated radio antenna and therear window defogger. When cleaning theglass on your vehicle, use only a soft cloth andglass cleaner.

Many cleaners contain solvents that may becomeconcentrated in your vehicle’s breathing space.Before using cleaners, read and adhere to all safetyinstructions on the label. While cleaning yourvehicle’s interior, maintain adequate ventilation byopening your vehicle’s doors and windows.

Dust may be removed from small buttons andknobs using a small brush with soft bristles.

Your dealer has a product for cleaning yourvehicle’s glass. Should it become necessary, youcan also obtain a product from your dealer toremove odors from your vehicle’s upholstery.

Do not clean your vehicle using the followingcleaners or techniques:

• Never use a knife or any other sharp object toremove a soil from any interior surface.

• Never use a stiff brush. It can cause damageto your vehicle’s interior surfaces.

• Never apply heavy pressure or rubaggressively with a cleaning cloth. Use ofheavy pressure can damage your interior anddoes not improve the effectiveness of soilremoval.

• Use only mild, neutral-pH soaps. Avoidlaundry detergents or dishwashing soaps withdegreasers. Using too much soap will leavea residue that leaves streaks and attracts dirt.For liquid cleaners, about 20 drops pergallon (3.78 L) of water is a good guide.

• Do not heavily saturate your upholstery whilecleaning.

• Damage to your vehicle’s interior may resultfrom the use of many organic solvents suchas naptha, alcohol, etc.

Fabric/CarpetUse a vacuum cleaner with a soft brushattachment frequently to remove dust and loosedirt. A canister vacuum with a beater bar inthe nozzle may only be used on floor carpet andcarpeted floor mats. For soils, always try to removethem first with plain water or club soda. Beforecleaning, gently remove as much of the soilas possible using one of the following techniques:

• For liquids: gently blot the remaining soil with apaper towel. Allow the soil to absorb into thepaper towel until no more can be removed.

• For solid dry soils: remove as much as possibleand then vacuum.

To clean, use the following instructions:

1. Saturate a lint-free, clean white cloth withwater or club soda.

2. Wring the cloth to remove excess moisture.

3. Start on the outside edge of the soil and gentlyrub toward the center. Continue cleaning,using a clean area of the cloth each time itbecomes soiled.

4. Continue to gently rub the soiled area until thecleaning cloth remains clean.

5. If the soil is not completely removed, use amild soap solution and repeat the cleaningprocess that was used with plain water.

If any of the soil remains, a commercial fabriccleaner or spot lifter may be necessary. When acommercial upholstery cleaner or spot lifter is to beused, test a small hidden area for colorfastnessfirst. If the locally cleaned area gives anyimpression that a ring formation may result, cleanthe entire surface.

After the cleaning process has been completed, apaper towel can be used to blot excess moisturefrom the fabric or carpet.

Sheet Metal DamageIf the vehicle is damaged and requires sheet metalrepair or replacement, make sure the body repairshop applies anti-corrosion material to partsrepaired or replaced to restore corrosion protection.

Original manufacturer replacement parts willprovide the corrosion protection while maintainingthe warranty.

Finish DamageAny stone chips, fractures or deep scratches inthe finish should be repaired right away. Baremetal will corrode quickly and may develop intomajor repair expense.

Minor chips and scratches can be repaired withtouch-up materials available from your dealer.Larger areas of finish damage can be corrected inyour dealer’s body and paint shop.

Underbody MaintenanceChemicals used for ice and snow removal anddust control can collect on the underbody. If theseare not removed, corrosion and rust can develop

on the underbody parts such as fuel lines, frame,floor pan, and exhaust system even thoughthey have corrosion protection.

At least every spring, flush these materials from theunderbody with plain water. Clean any areas wheremud and debris can collect. Dirt packed in closeareas of the frame should be loosened before beingflushed. Your dealer or an underbody car washingsystem can do this for you.

Chemical Paint SpottingSome weather and atmospheric conditions cancreate a chemical fallout. Airborne pollutants canfall upon and attack painted surfaces on thevehicle. This damage can take two forms: blotchy,ring-shaped discolorations, and small, irregulardark spots etched into the paint surface.

Although no defect in the paint job causes this, GMwill repair, at no charge to the owner, the surfacesof new vehicles damaged by this fallout conditionwithin 12 months or 12,000 miles (20 000 km) ofpurchase, whichever occurs first.

Vehicle Data Collection and EventData RecordersYour vehicle, like other modern motor vehicles,has a number of sophisticated computer systemsthat monitor and control several aspects of thevehicle’s performance. Your vehicle uses on-boardvehicle computers to monitor emission controlcomponents to optimize fuel economy, to monitorconditions for airbag deployment and, if soequipped, to provide anti-lock braking and to

help the driver control the vehicle in difficult drivingsituations. Some information may be storedduring regular operations to facilitate repair ofdetected malfunctions; other information is storedonly in a crash event by computer systems,such as those commonly called Event DataRecorders (EDR).

In a crash event, computer systems, such as theairbag Sensing and Diagnostic Module (SDM)in your vehicle may record information about thecondition of the vehicle and how it was operated,such as data related to engine speed, brakeapplication, throttle position, vehicle speed, safetybelt usage, airbag readiness, airbag performance,and the severity of a collision. If your vehicle isequipped with StabiliTrak®, steering performance,including yaw rate, steering wheel angle, andlateral acceleration, is also recorded. Thisinformation has been used to improve vehiclecrash performance and may be used to improvecrash performance of future vehicles and drivingsafety. Unlike the data recorders on manyairplanes, these on-board systems do notrecord sounds, such as conversation of vehicleoccupants.

Collision Damage RepairIf your vehicle is involved in a collision and it isdamaged, have the damage repaired by a qualifiedtechnician using the proper equipment andquality replacement parts. Poorly performedcollision repairs will diminish your vehicle’s resalevalue, and safety performance can becompromised in subsequent collisions.

472

Page 473: 2007 Buick Lucerne Owner Manual M - General Motors · 2007 Buick Lucerne Owner Manual M 1. Tires ... for Buick Motor Division whenever it appears in this manual. This manual describes

Collision PartsGenuine GM Collision parts are new parts madewith the same materials and construction methodsas the parts with which your vehicle was originallybuilt. Genuine GM Collision parts are your bestchoice to assure that your vehicle’s designedappearance, durability, and safety are preserved.The use of Genuine GM parts can help maintainyour GM New Vehicle Warranty.

Recycled original equipment parts may also beused for repair. These parts are typically removedfrom vehicles that were total losses in prioraccidents. In most cases, the parts being recycledare from undamaged sections of the vehicle.A recycled original equipment GM part, may be anacceptable choice to maintain your vehicle’soriginally designed appearance and safetyperformance, however, the history of these partsis not known. Such parts are not covered byyour GM New Vehicle Limited Warranty, and anyrelated failures are not covered by that warranty.

Aftermarket collision parts are also available.These are made by companies other than GMand may not have been tested for your vehicle.As a result, these parts may fit poorly, exhibitpremature durability/corrosion problems, and maynot perform properly in subsequent collisions.Aftermarket parts are not covered by your GMNew Vehicle Limited Warranty, and any vehiclefailure related to such parts are not covered by thatwarranty.

Repair FacilityGM also recommends that you choose a collisionrepair facility that meets your needs before youever need collision repairs. Your GM dealermay have a collision repair center with GM-trainedtechnicians and state of the art equipment, orbe able to recommend a collision repair center thathas GM-trained technicians and comparableequipment.

Insuring Your VehicleProtect your investment in your GM vehicle withcomprehensive and collision insurance coverage.There are significant differences in the qualityof coverage afforded by various insurance policyterms. Many insurance policies provide reducedprotection to your GM vehicle by limitingcompensation for damage repairs by usingaftermarket collision parts. Some insurancecompanies will not specify aftermarket collisionparts. When purchasing insurance, we recommendthat you assure your vehicle will be repairedwith GM original equipment collision parts. If suchinsurance coverage is not available from yourcurrent insurance carrier, consider switchingto another insurance carrier.

If your vehicle is leased, the leasing company mayrequire you to have insurance that assuresrepairs with Genuine GM Original EquipmentManufacturer (OEM) parts or GenuineManufacturer replacement parts. Read your leasecarefully, as you may be charged at the end ofyour lease for poor quality repairs.

If an Accident OccursHere is what to do if you are involved in anaccident.

• Try to relax and then check to make sure youare all right. If you are uninjured, make surethat no one else in your vehicle, or theother vehicle, is injured.

• If there has been an injury, call 911 for help.Do not leave the scene of an accident untilall matters have been taken care of. Moveyour vehicle only if its position puts youin danger or you are instructed to move it bya police officer.

• Give only the necessary and requestedinformation to police and other parties involvedin the accident. Do not discuss your personalcondition, mental frame of mind, or anythingunrelated to the accident. This will help guardagainst post-accident legal action.

• If you need roadside assistance, callGM Roadside Assistance. See RoadsideAssistance Program on page 466 for moreinformation.

474

• If your vehicle cannot be driven, know wherethe towing service will be taking it. Get acard from the tow truck operator or write downthe driver’s name, the service’s name, andthe phone number.

• Remove any valuables from your vehiclebefore it is towed away. Make sure thisincludes your insurance information andregistration if you keep these items in yourvehicle.

• Gather the important information you will needfrom the other driver. Things like name,address, phone number, driver’s licensenumber, vehicle license plate, vehicle make,model and model year, Vehicle IdentificationNumber (VIN), insurance company andpolicy number, and a general description ofthe damage to the other vehicle.

• If possible, call your insurance company fromthe scene of the accident. They will walk youthrough the information they will need.If they ask for a police report, phone or go tothe police department headquarters thenext day and you can get a copy of the reportfor a nominal fee. In some states/provinceswith “no fault” insurance laws, a report may notbe necessary. This is especially true if thereare no injuries and both vehicles are driveable.

• Choose a reputable collision repair facilityfor your vehicle. Whether you select aGM dealer or a private collision repair facilityto fix the damage, make sure you arecomfortable with them. Remember, you willhave to feel comfortable with their workfor a long time.

• Once you have an estimate, read it carefullyand make sure you understand what workwill be performed on your vehicle. If you havea question, ask for an explanation. Reputableshops welcome this opportunity.

Managing the Vehicle Damage RepairProcessIn the event that your vehicle requires damagerepairs, GM recommends that you take an activerole in its repair. If you have a pre-determinedrepair facility of choice, take your vehicle there, orhave it towed there. Specify to the facility thatany required replacement collision parts be originalequipment parts, either new Genuine GM partsor recycled original GM parts. Remember, recycledparts will not be covered by your GM vehiclewarranty.

Insurance pays the bill for the repair, but you mustlive with the repair. Depending on your policylimits, your insurance company may initially valuethe repair using aftermarket parts. Discuss thiswith your repair professional, and insist onGenuine GM parts.

Remember if your vehicle is leased you may beobligated to have the vehicle repaired withGenuine GM parts, even if your insurancecoverage does not pay the full cost.

If another party’s insurance company is paying forthe repairs, you are not obligated to accept arepair valuation based on that insurancecompany’s collision policy repair limits, as youhave no contractual limits with that company.In such cases, you can have control of the repairand parts choices as long as cost stays withinreasonable limits.
