{ Warning

Do not let anyone ride where asafety belt cannot be wornproperly. In a crash, if you or yourpassenger(s) are not wearingsafety belts, injuries can be muchworse than if you are wearingsafety belts. You can be seriouslyinjured or killed by hitting thingsinside the vehicle harder or bybeing ejected from the vehicle. Inaddition, anyone who is notbuckled up can strike otherpassengers in the vehicle.

It is extremely dangerous to ridein a cargo area, inside or outsideof a vehicle. In a collision,passengers riding in these areas

Why Safety Belts Work

When riding in a vehicle, you travelas fast as the vehicle does. If thevehicle stops suddenly, you keepgoing until something stops you.It could be the windshield, theinstrument panel, or the safety belts!

When you wear a safety belt, youand the vehicle slow down together.There is more time to stop becauseyou stop over a longer distance and,when worn properly, your strongestbones take the forces from the

safety belts. That is why wearingsafety belts makes such goodsense.

Questions and Answers AboutSafety Belts

Q: Will I be trapped in the vehicleafter a crash if I am wearing asafety belt?

A: You could be— whether you arewearing a safety belt or not.Your chance of being consciousduring and after a crash, so youcan unbuckle and get out, ismuch greater if you are belted.

Q: If my vehicle has airbags, whyshould I have to wear safetybelts?

A: Airbags are supplementalsystems only; so they work withsafety belts— not instead ofthem. Whether or not an airbagis provided, all occupants stillhave to buckle up to get themost protection.

Also, in nearly all states and inall Canadian provinces, the lawrequires wearing safety belts.

How to Wear Safety BeltsProperlyThis section is only for people ofadult size.

There are special things to knowabout safety belts and children. Andthere are different rules for smallerchildren and infants. If a child will beriding in the vehicle, see OlderChildren on page 3-32 or Infantsand Young Children on page 3-34.Follow those rules for everyone'sprotection.

It is very important for all occupantsto buckle up. Statistics show thatunbelted people are hurt more oftenin crashes than those who arewearing safety belts.

. Sit up straight and always keepyour feet on the floor in frontof you.

. Always use the correct bucklefor your seating position.

. Wear the lap part of the belt lowand snug on the hips, justtouching the thighs. In a crash,this applies force to the strongpelvic bones and you would beless likely to slide under the lapbelt. If you slid under it, the beltwould apply force on yourabdomen. This could causeserious or even fatal injuries.

. Wear the shoulder belt over theshoulder and across the chest.These parts of the body are bestable to take belt restrainingforces. The shoulder belt locks ifthere is a sudden stop or crash.

{ Warning

You can be seriously injured,or even killed, by not wearingyour safety belt properly.

. Never allow the lap orshoulder belt to becomeloose or twisted.

. Never wear the shoulder beltunder both arms or behindyour back.

. Never route the lap orshoulder belt over anarmrest.

Lap-Shoulder BeltAll seating positions in the vehiclehave a lap-shoulder belt.

The following instructions explainhow to wear a lap-shoulder beltproperly.

1. Adjust the seat, if the seat isadjustable, so you can sit upstraight. To see how, see “Seats”in the Index.

2. Pick up the latch plate and pullthe belt across you. Do not let itget twisted.

The lap-shoulder belt may lock ifyou pull the belt across you veryquickly. If this happens, let thebelt go back slightly to unlock it.Then pull the belt across youmore slowly.

If the shoulder portion of apassenger belt is pulled out allthe way, the child restraintlocking feature may be engaged.If this happens, let the belt goback all the way and start again.

3. Push the latch plate into thebuckle until it clicks.

Pull up on the latch plate tomake sure it is secure. If the beltis not long enough, see SafetyBelt Extender on page 3-18.

Position the release button onthe buckle so that the safety beltcould be quickly unbuckled ifnecessary.

If equipped with a shoulder beltheight adjuster, move it to theheight that is right for you. See“Shoulder Belt Height Adjuster”later in this section forinstructions on use andimportant safety information.

4. To make the lap part tight, pullup on the shoulder belt.

To unlatch the belt, push the buttonon the buckle. The belt shouldreturn to its stowed position.

Before a door is closed, be sure thesafety belt is out of the way. If adoor is slammed against a safetybelt, damage can occur to both thesafety belt and the vehicle.

Shoulder Belt Height Adjuster

The vehicle has a shoulder beltheight adjuster for the driver andright front passenger seatingpositions.

Adjust the height so the shoulderportion of the belt is on the shoulderand not falling off of it. The beltshould be close to, but notcontacting, the neck. Impropershoulder belt height adjustmentcould reduce the effectiveness ofthe safety belt in a crash. See Howto Wear Safety Belts Properly onpage 3-13.

Press the release button and movethe height adjuster to the desiredposition. The adjuster can be movedup by pushing the slide/trim up.After the adjuster is set to thedesired position, try to move it downwithout pushing the release buttonto make sure it has locked intoposition.

Safety Belt Pretensioners

This vehicle has safety beltpretensioners for front outboardoccupants. Although the safety beltpretensioners cannot be seen, theyare part of the safety belt assembly.

They can help tighten the safetybelts during the early stages of amoderate to severe frontal, nearfrontal, or rear crash if the thresholdconditions for pretensioneractivation are met. And, on vehicleswith side impact airbags, safety beltpretensioners can help tighten thesafety belts in a side crash orrollover event.

Pretensioners work only once. If thepretensioners activate in a crash,the pretensioners and probablyother parts of the vehicle's safetybelt system will need to be replaced.See Replacing Safety Belt SystemParts after a Crash on page 3-19.

4. Buckle, position, and release thesafety belt as describedpreviously in this section. Makesure the shoulder portion of thebelt is on the shoulder and notfalling off of it. The belt shouldbe close to, but not contacting,the neck.

Safety Belt Use DuringPregnancySafety belts work for everyone,including pregnant women. Like alloccupants, they are more likely tobe seriously injured if they do notwear safety belts.

A pregnant woman should wear alap-shoulder belt, and the lapportion should be worn as low aspossible, below the rounding,throughout the pregnancy.

The best way to protect the fetus isto protect the mother. When a safetybelt is worn properly, it is more likelythat the fetus will not be hurt in acrash. For pregnant women, as foranyone, the key to making safetybelts effective is wearing themproperly.

Safety Belt ExtenderIf the vehicle's safety belt will fastenaround you, you should use it.

But if a safety belt is not longenough, your dealer will order youan extender. When you go in toorder it, take the heaviest coat youwill wear, so the extender will belong enough for you. To help avoidpersonal injury, do not let someoneelse use it, and use it only for theseat it is made to fit. The extenderhas been designed for adults. Neveruse it for securing child seats. Towear it, attach it to the regular safetybelt. See the instruction sheet thatcomes with the extender.

. Seat-mounted side impactairbags for the second rowoutboard passengers.

All of the airbags have the wordAIRBAG embossed on the trim oron a label near the deploymentopening.

For frontal airbags, the wordAIRBAG is on the center of thesteering wheel for the driver and onthe instrument panel for the frontoutboard passenger.

For seat-mounted side impactairbags, the word AIRBAG is on theside of the seatback closest tothe door.

For roof-rail airbags, the wordAIRBAG is on the ceiling or trim.

Airbags are designed to supplementthe protection provided by safetybelts. Even though today's airbagsare also designed to help reducethe risk of injury from the force of aninflating bag, all airbags must inflatevery quickly to do their job.

Here are the most important thingsto know about the airbag system:

{ Warning

You can be severely injured orkilled in a crash if you are notwearing your safety belt, evenwith airbags. Airbags aredesigned to work with safetybelts, not replace them. Also,airbags are not designed to inflatein every crash. In some crashessafety belts are the only restraint.See When Should an AirbagInflate? on page 3-23.

Wearing your safety belt during acrash helps reduce the chance ofhitting things inside the vehicle orbeing ejected from it. Airbags are“supplemental restraints” to thesafety belts. Everyone in thevehicle should wear a safety beltproperly, whether or not there isan airbag for that person.

When Should an AirbagInflate?This vehicle is equipped withairbags. See Airbag System onpage 3-20. Airbags are designed toinflate if the impact exceeds thespecific airbag system's deploymentthreshold. Deployment thresholdsare used to predict how severe acrash is likely to be in time for theairbags to inflate and help restrainthe occupants. The vehicle haselectronic sensors that help theairbag system determine theseverity of the impact. Deploymentthresholds can vary with specificvehicle design.

Frontal airbags are designed toinflate in moderate to severe frontalor near frontal crashes to helpreduce the potential for severeinjuries, mainly to the driver's orfront outboard passenger's headand chest.

Whether the frontal airbags will orshould inflate is not based primarilyon how fast the vehicle is traveling.

It depends on what is hit, thedirection of the impact, and howquickly the vehicle slows down.

Frontal airbags may inflate atdifferent crash speeds depending onwhether the vehicle hits an objectstraight on or at an angle, andwhether the object is fixed ormoving, rigid or deformable, narrowor wide.

Frontal airbags are not intended toinflate during vehicle rollovers, rearimpacts, or in many side impacts.

In addition, the vehicle hasadvanced technology frontalairbags. Advanced technologyfrontal airbags adjust the restraintaccording to crash severity.

Seat-mounted side impact airbagsare designed to inflate in moderateto severe side crashes dependingon the location of the impact.Seat-mounted side impact airbagsare not designed to inflate in frontalimpacts, near frontal impacts,rollovers, or rear impacts.

A seat-mounted side impact airbagis designed to inflate on the side ofthe vehicle that is struck.

Roof-rail airbags are designed toinflate in moderate to severe sidecrashes depending on the locationof the impact. In addition, theseroof-rail airbags are designed toinflate during a rollover or in asevere frontal impact. Roof-railairbags are not designed to inflate inrear impacts. Both roof-rail airbagswill inflate when either side of thevehicle is struck, if the sensingsystem predicts that the vehicle isabout to roll over on its side, or in asevere frontal impact.

In any particular crash, no one cansay whether an airbag should haveinflated simply because of thevehicle damage or repair costs.

What Makes an AirbagInflate?In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from the

For airbag locations, see Where Arethe Airbags? on page 3-21.

How Does an AirbagRestrain?In moderate to severe frontal ornear frontal collisions, even beltedoccupants can contact the steeringwheel or the instrument panel. Inmoderate to severe side collisions,even belted occupants can contactthe inside of the vehicle.

Airbags supplement the protectionprovided by safety belts bydistributing the force of the impactmore evenly over theoccupant's body.

Rollover capable roof-rail airbagsare designed to help contain thehead and chest of occupants in theoutboard seating positions in the

first and second rows. The rollovercapable roof-rail airbags aredesigned to help reduce the risk offull or partial ejection in rolloverevents, although no system canprevent all such ejections.

But airbags would not help in manytypes of collisions, primarilybecause the occupant's motion isnot toward those airbags. See WhenShould an Airbag Inflate? onpage 3-23.

Airbags should never be regardedas anything more than a supplementto safety belts.

What Will You See afteran Airbag Inflates?After the frontal airbags andseat-mounted side impact airbagsinflate, they quickly deflate, soquickly that some people may noteven realize an airbag inflated.Roof-rail airbags may still be at leastpartially inflated for some time afterthey inflate. Some components ofthe airbag module may be hot for

several minutes. For location of theairbags, see Where Are theAirbags? on page 3-21.

The parts of the airbag that comeinto contact with you may be warm,but not too hot to touch. There maybe some smoke and dust comingfrom the vents in the deflatedairbags. Airbag inflation does notprevent the driver from seeing out ofthe windshield or being able to steerthe vehicle, nor does it preventpeople from leaving the vehicle.

{ Warning

When an airbag inflates, theremay be dust in the air. This dustcould cause breathing problemsfor people with a history ofasthma or other breathing trouble.To avoid this, everyone in thevehicle should get out as soon asit is safe to do so. If you havebreathing problems but cannotget out of the vehicle after an

Use caution if you should attemptto restart the engine after a crashhas occurred.

In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.Additional windshield breakage mayalso occur from the front outboardpassenger airbag.. Airbags are designed to inflate

only once. After an airbaginflates, you will need some newparts for the airbag system.If you do not get them, theairbag system will not be there

to help protect you in anothercrash. A new system will includeairbag modules and possiblyother parts. The service manualfor the vehicle covers the needto replace other parts.

. The vehicle has a crash sensingand diagnostic module whichrecords information after acrash. See Vehicle DataRecording and Privacy onpage 13-13 and Event DataRecorders on page 13-14.

The passenger sensing systemturns off the front outboardpassenger frontal airbag undercertain conditions. No other airbagis affected by the passengersensing system.

The passenger sensing systemworks with sensors that are part ofthe front outboard passenger seat.The sensors are designed to detectthe presence of a properly-seatedoccupant and determine if the frontoutboard passenger frontal airbagshould be allowed to inflate or not.

According to accident statistics,children are safer when properlysecured in a rear seat in the correctchild restraint for their weightand size.

Whenever possible, children aged12 and under should be secured ina rear seating position.

Never put a rear-facing child seat inthe front. This is because the risk tothe rear-facing child is so great,if the airbag inflates.

{ Warning

A child in a rear-facing childrestraint can be seriously injuredor killed if the passenger frontalairbag inflates. This is becausethe back of the rear-facing childrestraint would be very close tothe inflating airbag. A child in aforward-facing child restraint canbe seriously injured or killed if thepassenger frontal airbag inflatesand the passenger seat is in aforward position.

Even if the passenger sensingsystem has turned off thepassenger frontal airbag, nosystem is fail-safe. No one canguarantee that an airbag will notinflate under some unusualcircumstance, even though theairbag is off.

Warning (Continued)

Secure rear-facing child restraintsin a rear seat, even if the airbagis off. If you secure aforward-facing child restraint inthe front outboard passengerseat, always move the seat as farback as it will go. It is better tosecure the child restraint in arear seat.

The passenger sensing system isdesigned to turn off the frontoutboard passenger frontal airbag if:. The front outboard passenger

seat is unoccupied.. The system determines that an

infant is present in a childrestraint.

. A front outboard passengertakes his/her weight off of theseat for a period of time.

. There is a critical problem withthe airbag system or thepassenger sensing system.

When the passenger sensingsystem has turned off the frontoutboard passenger frontal airbag,the off indicator will light and stay litas a reminder that the airbag is off.See Passenger Airbag StatusIndicator on page 5-15.

The passenger sensing system isdesigned to turn on the frontoutboard passenger frontal airbaganytime the system senses that aperson of adult size is sittingproperly in the front outboardpassenger seat. When thepassenger sensing system hasallowed the airbag to be enabled,the on indicator will light and stay litas a reminder that the airbag isactive.

For some children, includingchildren in child restraints and forvery small adults, the passengersensing system may or may not turnoff the front outboard passengerfrontal airbag, depending upon the

person's seating posture and bodybuild. Everyone in the vehiclewho has outgrown childrestraints should wear a safety beltproperly — whether or not there isan airbag for that person.

{ Warning

If the airbag readiness light evercomes on and stays on, it meansthat something may be wrongwith the airbag system. To helpavoid injury to yourself or others,have the vehicle serviced rightaway. See Airbag ReadinessLight on page 5-14 for moreinformation, including importantsafety information.

If the On Indicator Is Lit for aChild Restraint

The passenger sensing system isdesigned to turn off the frontoutboard passenger frontal airbag ifthe system determines that an infantis present in a child restraint. If achild restraint has been installedand the on indicator is lit:

1. Turn the vehicle off.

2. Remove the child restraint fromthe vehicle.

3. Remove any additional itemsfrom the seat such as blankets,cushions, seat covers, seatheaters, or seat massagers.

4. Reinstall the child restraintfollowing the directions providedby the child restraintmanufacturer and refer toSecuring Child Restraints (RearSeat) on page 3-47 or SecuringChild Restraints (FrontPassenger Seat) on page 3-49.

5. If, after reinstalling the childrestraint and restarting thevehicle, the on indicator is still lit,turn the vehicle off. Then slightlyrecline the vehicle seatback andadjust the seat cushion,if adjustable, to make sure thatthe vehicle seatback is notpushing the child restraint intothe seat cushion.

Also make sure the childrestraint is not trapped under thevehicle head restraint. If thishappens, adjust the headrestraint. See Head Restraintson page 3-2.

6. Restart the vehicle.

The passenger sensing system mayor may not turn off the airbag for achild in a child restraint dependingupon the child's size. It is better tosecure the child restraint in arear seat.

If the Off Indicator Is Lit for anAdult-Sized Occupant

If a person of adult-size is sitting inthe front outboard passenger seat,but the off indicator is lit, it could bebecause that person is not sittingproperly in the seat. Use thefollowing steps to allow the systemto detect that person and enable thefront outboard passenger frontalairbag :

1. Turn the vehicle off.

serious injury or even death. Anadult-sized occupant should notride in the front outboardpassenger seat, if the passengerairbag off indicator is lit.

Additional Factors AffectingSystem Operation

Safety belts help keep thepassenger in position on the seatduring vehicle maneuvers andbraking, which helps the passengersensing system maintain thepassenger airbag status. See“Safety Belts” and “Child Restraints”in the Index for additionalinformation about the importance ofproper restraint use.

A thick layer of additional material,such as a blanket or cushion,or aftermarket equipment such asseat covers, seat heaters, and seatmassagers can affect how well thepassenger sensing system

operates. We recommend that younot use seat covers or otheraftermarket equipment except whenapproved by GM for your specificvehicle. See Adding Equipment tothe Airbag-Equipped Vehicle onpage 3-30 for more informationabout modifications that can affecthow the system operates.

A wet seat can affect theperformance of the passengersensing system. Here is how:. The passenger sensing system

may turn off the passengerfrontal airbag when liquid issoaked into the seat. If thishappens, the off indicator will belit, and the airbag readiness lighton the instrument cluster willalso be lit.

. Liquid pooled on the seat thathas not soaked in may make itmore likely that the passengersensing system will turn on thepassenger frontal airbag while achild restraint or child occupant

If the passenger seat gets wet, drythe seat immediately. If the airbagreadiness light is lit, do not install achild restraint or allow anyone tooccupy the seat. See AirbagReadiness Light on page 5-14 forimportant safety information.

The on indicator may be lit if anobject, such as a briefcase,handbag, grocery bag, laptop orother electronic device, is put on anunoccupied seat. If this is notdesired remove the object fromthe seat.

{ Warning

Stowing of articles under thepassenger seat or between thepassenger seat cushion andseatback may interfere with theproper operation of the passengersensing system.

Servicing theAirbag-Equipped VehicleAirbags affect how the vehicleshould be serviced. There are partsof the airbag system in severalplaces around the vehicle. Yourdealer and the service manual haveinformation about servicing thevehicle and the airbag system. Topurchase a service manual, seeService Publications OrderingInformation on page 13-11.

{ Warning

For up to 10 seconds after thevehicle is turned off and thebattery is disconnected, an airbagcan still inflate during improperservice. You can be injured if youare close to an airbag when itinflates. Avoid yellow connectors.They are probably part of theairbag system. Be sure to follow

Your dealer and the service manualhave information about the locationof the airbag sensors, sensing anddiagnostic module, and airbagwiring.

In addition, the vehicle has apassenger sensing system for thefront outboard passenger position,which includes sensors that are partof the passenger seat. Thepassenger sensing system may notoperate properly if the original seattrim is replaced with non-GMcovers, upholstery, or trim; or withGM covers, upholstery, or trimdesigned for a different vehicle. Anyobject, such as an aftermarket seatheater or a comfort-enhancing pador device, installed under or on topof the seat fabric, could alsointerfere with the operation of thepassenger sensing system. Thiscould either prevent properdeployment of the passengerairbag(s) or prevent the passengersensing system from properly

turning off the passenger airbag(s).See Passenger Sensing System onpage 3-25.

If the vehicle has rollover roof-railairbags, see Different Size Tiresand Wheels on page 10-59 foradditional important information.

Seats and Restraints 3-33

The manufacturer instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat with alap-shoulder belt until the childpasses the fit test below:. Sit all the way back on the seat.

Do the knees bend at the seatedge? If yes, continue. If no,return to the booster seat.

. Buckle the lap-shoulder belt.Does the shoulder belt rest onthe shoulder? If yes, continue.If no, try using the rear safetybelt comfort guide. See “RearSafety Belt Comfort Guides”under Lap-Shoulder Belt onpage 3-14. If the shoulder beltstill does not rest on theshoulder, then return to thebooster seat.

. Does the lap belt fit low andsnug on the hips, touching thethighs? If yes, continue. If no,return to the booster seat.

. Can proper safety belt fit bemaintained for the length of thetrip? If yes, continue. If no,return to the booster seat.

Q: What is the proper way towear safety belts?

A: An older child should wear alap-shoulder belt and get theadditional restraint a shoulderbelt can provide. The shoulderbelt should not cross the face orneck. The lap belt should fitsnugly below the hips, justtouching the top of the thighs.This applies belt force to thechild's pelvic bones in a crash.It should never be worn over theabdomen, which could causesevere or even fatal internalinjuries in a crash.

Also see “Rear Safety Belt ComfortGuides” under Lap-Shoulder Belt onpage 3-14.

According to accident statistics,children are safer when properlyrestrained in a rear seating position.

In a crash, children who are notbuckled up can strike other peoplewho are buckled up, or can bethrown out of the vehicle. Olderchildren need to use safety beltsproperly.

{ Warning

Never allow more than one childto wear the same safety belt. Thesafety belt cannot properly spreadthe impact forces. In a crash, theycan be crushed together andseriously injured. A safety beltmust be used by only one personat a time.

Every time infants and youngchildren ride in vehicles, they shouldhave the protection provided byappropriate child restraints. Neitherthe vehicle's safety belt system norits airbag system is designedfor them.

Children who are not restrainedproperly can strike other people,or can be thrown out of the vehicle.

{ Warning

Never hold an infant or a childwhile riding in a vehicle. Due tocrash forces, an infant or a childwill become so heavy it is notpossible to hold it during a crash.For example, in a crash at only40 km/h (25 mph), a 5.5 kg (12 lb)infant will suddenly become a110 kg (240 lb) force on a person'sarms. An infant should besecured in an appropriaterestraint.

For most basic types of childrestraints, there are manydifferent models available. Whenpurchasing a child restraint, besure it is designed to be used ina motor vehicle. If it is, therestraint will have a label sayingthat it meets federal motorvehicle safety standards.

The restraint manufacturerinstructions that come with therestraint state the weight andheight limitations for a particularchild restraint. In addition, thereare many kinds of restraintsavailable for children withspecial needs.

{ Warning

To reduce the risk of neck andhead injury during a crash, infantsneed complete support. In acrash, if an infant is in arear-facing child restraint, thecrash forces can be distributedacross the strongest part of aninfant's body, the back andshoulders. Infants should alwaysbe secured in rear-facing childrestraints.

Securing an Add-On ChildRestraint in the Vehicle

{ Warning

A child can be seriously injured orkilled in a crash if the childrestraint is not properly secured inthe vehicle. Secure the childrestraint properly in the vehicleusing the vehicle safety belt orLATCH system, following theinstructions that came with thatchild restraint and the instructionsin this manual.

To help reduce the chance of injury,the child restraint must be securedin the vehicle. Child restraintsystems must be secured in vehicleseats by lap belts or the lap beltportion of a lap-shoulder belt, or bythe LATCH system. See LowerAnchors and Tethers for Children(LATCH System) on page 3-40.

Children can be endangered in acrash if the child restraint is notproperly secured in the vehicle.

When securing an add-on childrestraint, refer to the instructionsthat come with the restraint whichmay be on the restraint itself or in abooklet, or both, and to this manual.The child restraint instructions areimportant, so if they are notavailable, obtain a replacementcopy from the manufacturer.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle— even when no child isin it.

In some areas of the United Statesand Canada, Certified ChildPassenger Safety Technicians(CPSTs) are available to inspectand demonstrate how to correctlyuse and install child restraints. Inthe U.S., refer to the NationalHighway Traffic Safety

Administration (NHTSA) website tolocate the nearest child safety seatinspection station. For CPSTavailability in Canada, check withTransport Canada or the ProvincialMinistry of Transportation office.

Seats and Restraints 3-39

Whenever possible, children aged12 and under should be secured ina rear seating position.

Never put a rear-facing child seat inthe front. This is because the risk tothe rear-facing child is so great if theairbag deploys.

{ Warning

A child in a rear-facing childrestraint can be seriously injuredor killed if the front passengerairbag inflates. This is becausethe back of the rear-facing childrestraint would be very close tothe inflating airbag. A child in aforward-facing child restraint canbe seriously injured or killed if thefront passenger airbag inflatesand the passenger seat is in aforward position.

Even if the passenger sensingsystem has turned off the frontpassenger frontal airbag, no

system is fail-safe. No one canguarantee that an airbag will notdeploy under some unusualcircumstance, even though it isturned off.

Secure rear-facing child restraintsin a rear seat, even if the airbagis off. If you secure aforward-facing child restraint inthe front seat, always move thefront passenger seat as far backas it will go. It is better to securethe child restraint in a rear seat.

See Passenger Sensing Systemon page 3-25 for additionalinformation.

When securing a child restraint in arear seating position, study theinstructions that came with the childrestraint to make sure it iscompatible with this vehicle.

Child restraints and booster seatsvary considerably in size, and somemay fit in certain seating positionsbetter than others. Always makesure the child restraint is properlysecured.

Depending on where you place thechild restraint and the size of thechild restraint, you may not be ableto access adjacent safety beltassemblies or LATCH anchors foradditional passengers or childrestraints. Adjacent seatingpositions should not be used if thechild restraint prevents access to orinterferes with the routing of thesafety belt.

Wherever a child restraint isinstalled, be sure to secure the childrestraint properly.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle — even when no child isin it.

3-40 Seats and Restraints

Lower Anchors andTethers for Children(LATCH System)The LATCH system secures a childrestraint during driving or in a crash.LATCH attachments on the childrestraint are used to attach the childrestraint to the anchors in thevehicle. The LATCH system isdesigned to make installation of achild restraint easier.

In order to use the LATCH system inyour vehicle, you need a childrestraint that has LATCHattachments. LATCH-compatiblerear-facing and forward-facing childseats can be properly installedusing either the LATCH anchors orthe vehicle’s safety belts. Do notuse both the safety belts and theLATCH anchorage system to securea rear-facing or forward-facingchild seat.

Booster seats use the vehicle’ssafety belts to secure the child inthe booster seat. If the manufacturer

recommends that the booster seatbe secured with the LATCH system,this can be done as long as thebooster seat can be positionedproperly and there is no interferencewith the proper positioning of thelap-shoulder belt on the child.

Make sure to follow the instructionsthat came with the child restraint,and also the instructions in thismanual.

When installing a child restraint witha top tether, you must also useeither the lower anchors or thesafety belts to properly secure thechild restraint. A child restraint mustnever be installed using only the toptether and anchor.

The LATCH anchorage system canbe used until the combined weightof the child plus the child restraint is29.5 kg (65 lbs). Use the safety beltalone instead of the LATCHanchorage system once thecombined weight is more than29.5 kg (65 lbs).

The following explains how to attacha child restraint with theseattachments in the vehicle.

Not all vehicle seating positions orchild restraints have lower anchorsand attachments or top tetheranchors and attachments.

Lower Anchors

Lower anchors (1) are metal barsbuilt into the vehicle. There are twolower anchors for each LATCHseating position that willaccommodate a child restraint withlower attachments (2).

Top Tether Anchor

A top tether (3, 4) anchors the top ofthe child restraint to the vehicle.A top tether anchor is built into thevehicle. The top tetherattachment (2) on the child restraintconnects to the top tether anchor inthe vehicle in order to reduce theforward movement and rotation ofthe child restraint during driving or ina crash.

The child restraint may have asingle tether (3) or a dual tether (4).Either will have a singleattachment (2) to secure the toptether to the anchor.

Some child restraints that have atop tether are designed for use withor without the top tether beingattached. Others require the toptether always to be attached. InCanada, the law requires thatforward-facing child restraints havea top tether, and that the tether beattached. Be sure to read and followthe instructions for the childrestraint.

To assist in locating the loweranchors, each rear anchor positionhas a label, near the creasebetween the seatback and the seatcushion.

To assist in locating the top tetheranchors, the top tether anchorsymbol is on the cover.

The top tether anchors are underthe covers, behind the rear seat, onthe filler panel. Be sure to use ananchor on the same side of thevehicle as the seating positionwhere the child restraint will beplaced.

Do not secure a child restraint in aposition without a top tether anchorif a national or local law requiresthat the top tether be attached, or ifthe instructions that come with thechild restraint say that the top tethermust be attached.

According to accident statistics,children and infants are safer whenproperly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition. See Where to Put theRestraint on page 3-38 foradditional information.

Securing a Child RestraintDesigned for the LATCHSystem

{ Warning

If a LATCH-type child restraint isnot attached to anchors, the childrestraint will not be able to protectthe child correctly. In a crash, thechild could be seriously injured orkilled. Install a LATCH-type childrestraint properly using theanchors, or use the vehicle safetybelts to secure the restraint,following the instructions thatcame with the child restraint andthe instructions in this manual.

restraint to a single anchor couldcause the anchor or attachmentto come loose or even breakduring a crash. A child or otherscould be injured. To reduce therisk of serious or fatal injuriesduring a crash, attach only onechild restraint per anchor.

{ Warning

Children can be seriously injuredor strangled if a shoulder belt iswrapped around their neck andthe safety belt continues totighten. Buckle any unused safetybelts behind the child restraint sochildren cannot reach them. Pullthe shoulder belt all the way outof the retractor to set the lock,if the vehicle has one, after thechild restraint has been installed.

{ Caution

Do not let the LATCHattachments rub against thevehicle’s safety belts. This maydamage these parts. If necessary,move buckled safety belts toavoid rubbing the LATCHattachments.

Do not fold the empty rear seatwith a safety belt buckled. Thiscould damage the safety belt orthe seat. Unbuckle and return thesafety belt to its stowed position,before folding the seat.

If you need to secure more than onechild restraint in the rear seat, seeWhere to Put the Restraint onpage 3-38.

You cannot secure three childrestraints using the LATCH anchorsin the rear seat at the same time,but you can install two of them.

If you want to do this, install oneLATCH child restraint in the rightrear seating position, and install theother one either in the left rearseating position or in the centerseating position. If you need toinstall child restraints in both thecenter and left rear seatingpositions, the one in the centerseating position will need to besecured using the vehicle safetybelts instead of the LATCH anchors.

Refer to the following illustration tolearn which anchors to use.

Charging System Light

The charging system light comes onbriefly when the ignition is turnedon, but the engine is not running, asa check to show the light is working.The light turns off when the engineis started. If it does not, have thevehicle serviced by your dealer.

If the light stays on, or comes onwhile driving, there could be aproblem with the electrical chargingsystem. Have it checked by yourdealer. Driving while this light is oncould drain the battery.

If a short distance must be drivenwith the light on, be sure to turn offall accessories, such as the radioand air conditioner.

MalfunctionIndicator LampA computer system called OBD II(On-Board Diagnostics-SecondGeneration) monitors the operationof the vehicle to ensure emissionsare at acceptable levels, helping tomaintain a clean environment. Themalfunction indicator lamp comeson when the vehicle is placed inON/RUN for key access or ServiceOnly Mode for Keyless Access, as acheck to show it is working. If itdoes not, have the vehicle servicedby your dealer. See IgnitionPositions (Key Access) onpage 9-15 or Ignition Positions(Keyless Access) on page 9-16 formore information.

If the malfunction indicator lampcomes on while the engine isrunning, this indicates that theOBD II system has detected aproblem and diagnosis and servicemight be required.

Malfunctions often are indicated bythe system before any problem isapparent. Being aware of the lightcan prevent more serious damageto the vehicle. This system alsoassists the dealer technician incorrectly diagnosing anymalfunction.

{ Caution

If the vehicle is continually drivenwith this light on, the emissioncontrols might not work as well,the vehicle fuel economy mightnot be as good, and the enginemight not run as smoothly. Thiscould lead to costly repairs thatmight not be covered by thevehicle warranty.

{ Caution

Modifications made to the engine,transmission, exhaust, intake,or fuel system of the vehicle orthe replacement of the originaltires with other than those of thesame Tire Performance Criteria(TPC) can affect the vehicle'semission controls and can causethis light to come on.Modifications to these systemscould lead to costly repairs notcovered by the vehicle warranty.This could also result in a failureto pass a required EmissionInspection/Maintenance test. SeeAccessories and Modifications onpage 10-3.

This light comes on during amalfunction in one of two ways:

Light Flashing: A misfire conditionhas been detected. A misfireincreases vehicle emissions and

could damage the emission controlsystem on the vehicle. Diagnosisand service might be required.

To prevent more serious damage tothe vehicle:. Reduce vehicle speed.. Avoid hard accelerations.. Avoid steep uphill grades.. If towing a trailer, reduce the

amount of cargo being hauled assoon as it is possible.

If the light continues to flash, find asafe place to stop and park thevehicle. Turn the vehicle off, wait atleast 10 seconds, and restart theengine. If the light is still flashing,follow the previous steps and seeyour dealer for service as soon aspossible.

Light On Steady: An emissioncontrol system malfunction hasbeen detected on the vehicle.Diagnosis and service might berequired.

The following may correct anemission control systemmalfunction:. Check that the fuel cap is fully

installed. See Filling the Tank onpage 9-61. The diagnosticsystem can determine if the fuelcap has been left off orimproperly installed. A loose ormissing fuel cap allows fuel toevaporate into the atmosphere.A few driving trips with the capproperly installed should turn thelight off.

. Check that good quality fuel isused. Poor fuel quality causesthe engine not to run asefficiently as designed and maycause stalling after start-up,stalling when the vehicle ischanged into gear, misfiring,hesitation on acceleration,or stumbling on acceleration.These conditions might go awayonce the engine is warmed up.

If one or more of these conditionsoccurs, change the fuel brand used.It may require at least one full tankof the proper fuel to turn the light off.

See Recommended Fuel onpage 9-58.

If none of the above have made thelight turn off, your dealer can checkthe vehicle. The dealer has theproper test equipment anddiagnostic tools to fix anymechanical or electrical problemsthat might have developed.

Emissions Inspection andMaintenance Programs

Depending on where you live, yourvehicle may be required toparticipate in an emission controlsystem inspection and maintenanceprogram. For the inspection, theemission system test equipment willlikely connect to the vehicle's DataLink Connector (DLC).

The DLC is under the instrumentpanel next to the steering wheel.See your dealer if assistance isneeded.

The vehicle may not passinspection if:. The malfunction indicator lamp is

on while the engine is running,or the malfunction indicator lampis not on while the vehicle is inON/RUN or Service Only Mode.See your dealer for assistance inverifying proper operation of themalfunction indicator lamp.

. The OBD II (On-BoardDiagnostics) system determinesthat critical emission controlsystems have not beencompletely diagnosed by thesystem. If this were to occur, thevehicle would be considered notready for inspection. This canhappen if the 12-volt battery hasrecently been replaced orrun down.

The diagnostic system isdesigned to evaluate criticalemission control systems duringnormal driving. This can takeseveral days of driving. If thishas been done and the vehiclestill does not pass the inspectionfor lack of OBD II systemreadiness, your dealer canprepare the vehicle forinspection.

Do not use the Universal Remotesystem with any garage door openerthat does not have the stop andreverse feature. This includes anygarage door opener modelmanufactured before April 1, 1982.

Read these instructions completelybefore programming the UniversalRemote system. It may help to haveanother person assist with theprogramming process.

Keep the original hand-heldtransmitter for use in other vehiclesas well as for future programming.Erase the programming whenvehicle ownership is terminated.See “Erasing Universal RemoteSystem Buttons” later in thissection.

To program a garage door opener,park outside directly in line with andfacing the garage door openerreceiver. Clear all people andobjects near the garage door.

Make sure the hand-held transmitterhas a new battery for quick andaccurate transmission of theradio-frequency signal.

Programming the UniversalRemote System

For questions or help programmingthe Universal Remote system, call1-800-355-3515 or seewww.homelink.com.

Programming involvestime-sensitive actions, and may timeout causing the procedure to berepeated.

To program up to three devices:

1. Hold the end of the hand-heldtransmitter about 3 to 8 cm (1 to3 in) away from the UniversalRemote system buttons with theindicator light in view. The

Battery LoadManagementThe vehicle has Electric PowerManagement (EPM) that estimatesthe battery's temperature and stateof charge. It then adjusts the voltagefor best performance and extendedlife of the battery.

When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver InformationCenter (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.

The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.

This is because the generator(alternator) may not be spinning fastenough at idle to produce all of thepower needed for very highelectrical loads.

A high electrical load occurs whenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.

EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to the

Climate Control Influence oneAssist Operation and FuelEconomy (If Equipped)

The climate control system dependson other vehicle systems for heatand power input. Certain climatecontrol settings can lead to higherfuel usage and/or fewer auto stops.

The following are climate controlsettings that use more fuel:. Comfort air conditioning mode.. The defrost mode.

. Extreme temperature settings,such as 15°C (60°F) or 32°C(90°F).

. High fan speed settings.

To help reduce fuel usage:. Use the full automatic control as

described under “AutomaticOperation.”

. Select a temperature setting thatis higher in hot weather andlower in cold weather.

. Turn off the air conditioningwhen it is not needed.

. Only use defrost to clear thewindows.

Automatic Operation

{ Warning

Taking your eyes off the road toolong or too often could cause acrash resulting in injury or death.Focus your attention on driving.

Refer to the Infotainment manual formore information on using thatsystem, including pairing and usinga cell phone

Defensive DrivingDefensive driving means “alwaysexpect the unexpected.” The firststep in driving defensively is to wearthe safety belt. See Safety Belts onpage 3-12.. Assume that other road users

(pedestrians, bicyclists, andother drivers) are going to becareless and make mistakes.Anticipate what they might doand be ready.

. Allow enough following distancebetween you and the driver infront of you.

. Focus on the task of driving.

Drunk DrivingDeath and injury associated withdrinking and driving is a globaltragedy.

{ Warning

Drinking and then driving is verydangerous. Your reflexes,perceptions, attentiveness, andjudgment can be affected by evena small amount of alcohol. Youcan have a serious — or evenfatal — collision if you drive afterdrinking.

Do not drink and drive or ride witha driver who has been drinking.Ride home in a cab; or if you arewith a group, designate a driverwho will not drink.

Control of a VehicleBraking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.

BrakingBraking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.

Average driver reaction time isabout three-quarters of a second. Inthat time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.

Helpful braking tips to keep in mindinclude:. Keep enough distance between

you and the vehicle in frontof you.

. Avoid needless heavy braking.

. Keep pace with traffic.

9-4 Driving and Operating

If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be somepower brake assist but it will beused when the brake is applied.Once the power assist is used up, itcan take longer to stop and thebrake pedal will be harder to push.

Steering

Electric Power Steering

If the vehicle has electric powersteering it does not have powersteering fluid. Regular maintenanceis not required.

If power steering assist is lost dueto a system malfunction, the vehiclecan be steered, but may requireincreased effort.

See your dealer if there is aproblem.

If the steering wheel is turned until itreaches the end of its travel and isheld against that position for anextended period of time, powersteering assist may be reduced.

If the steering assist is used for anextended period of time, powerassist may be reduced.

Normal use of the power steeringassist should return when thesystem cools down.

See specific vehicle steeringmessages under Vehicle Messageson page 5-34.

Variable Effort Steering

Some vehicles have a steeringsystem that varies the amount ofeffort required to steer the vehicle inrelation to the speed of the vehicle.

The amount of steering effortrequired is less at slower speeds tomake the vehicle moremaneuverable and easier to park. Atfaster speeds, the steering effort

increases to provide a sport-like feelto the steering. This providesmaximum control and stability.

If the vehicle seems harder to steerthan normal when parking or drivingslowly, there may be a problem withthe system. You will still have powersteering, but steering will be stifferthan normal at slow speeds. Seeyour dealer for service.

Hydraulic Power Steering

If the vehicle has hydraulic powersteering, it may requiremaintenance. See Power SteeringFluid (2.4L L4 Engine and 3.6LV6 Engine with FWD) onpage 10-23 or Power Steering Fluid(3.6L V6 Engine with AWD) onpage 10-23.

If power steering assist is lostbecause the engine stops or asystem malfunction, the vehicle canbe steered but may requireincreased effort. See your dealer ifthere is a problem.

Driving and Operating 9-5

{ Caution

If the steering wheel is turneduntil it reaches the end of itstravel, and is held in that positionfor more than 15 seconds,damage may occur to the powersteering system and there may beloss of power steering assist.

Curve Tips. Take curves at a reasonable

speed.. Reduce speed before entering a

curve.. Maintain a reasonable steady

speed through the curve. Wait until the vehicle is out of

the curve before acceleratinggently into the straightaway.

Steering in Emergencies. There are some situations when

steering around a problem maybe more effective than braking.

. Holding both sides of thesteering wheel allows you to turn180 degrees without removinga hand.

. Antilock Brake System (ABS)allows steering while braking.

Off-Road Recovery

The vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving. Followthese tips:

1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so that itstraddles the edge of thepavement.

2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.

3. Turn the steering wheel to gostraight down the roadway.

Loss of Control

Skidding

There are three types of skids thatcorrespond to the vehicle's threecontrol systems:. Braking Skid — wheels are not

rolling.

9-6 Driving and Operating

. Steering or CorneringSkid — too much speed orsteering in a curve causes tiresto slip and lose cornering force.

. Acceleration Skid — too muchthrottle causes the drivingwheels to spin.

Defensive drivers avoid most skidsby taking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.

If the vehicle starts to slide, followthese suggestions:. Ease your foot off the

accelerator pedal and steer theway you want the vehicle to go.The vehicle may straighten out.Be ready for a second skid if itoccurs.

. Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or other

material on the road. Learn torecognize warning clues — suchas enough water, ice, or packedsnow on the road to make amirrored surface — and slowdown when you have any doubt.

. Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.

Remember: Antilock brakes helpavoid only the braking skid.

Driving on Wet RoadsRain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep‐standing or flowing water.

{ Warning

Wet brakes can cause crashes.They might not work as well in aquick stop and could causepulling to one side. You couldlose control of the vehicle.

After driving through a largepuddle of water or a car/vehiclewash, lightly apply the brakepedal until the brakes worknormally.

Flowing or rushing water createsstrong forces. Driving throughflowing water could cause thevehicle to be carried away. If thishappens, you and other vehicleoccupants could drown. Do notignore police warnings and bevery cautious about trying to drivethrough flowing water.

Hydroplaning

Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road iswet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.

There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.

Other Rainy Weather Tips

Besides slowing down, other wetweather driving tips include:. Allow extra following distance.. Pass with caution.. Keep windshield wiping

equipment in good shape.. Keep the windshield washer fluid

reservoir filled.. Have good tires with proper

tread depth. See Tires onpage 10-42.

. Turn off cruise control.

Highway HypnosisAlways be alert and pay attention toyour surroundings while driving.If you become tired or sleepy, find asafe place to park the vehicleand rest.

Other driving tips include:. Keep the vehicle well ventilated.. Keep the interior

temperature cool.. Keep your eyes moving — scan

the road ahead and to the sides.. Check the rearview mirror and

vehicle instruments often.

Hill and Mountain RoadsDriving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips fordriving in these conditions include:. Keep the vehicle serviced and in

good shape.

. Check all fluid levels and brakes,tires, cooling system, andtransmission.

. Shift to a lower gear when goingdown steep or long hills.

{ Warning

Using the brakes to slow thevehicle on a long downhill slopecan cause brake overheating, canreduce brake performance, andcould result in a loss of braking.Shift the transmission to a lowergear to let the engine assist thebrakes on a steep downhill slope.

{ Warning

Coasting downhill in N (Neutral)or with the ignition off isdangerous. This can causeoverheating of the brakes and

. Pay attention to special roadsigns (falling rocks area, windingroads, long grades, passing orno-passing zones) and takeappropriate action.

Winter Driving

Driving on Snow or Ice

Drive carefully when there is snowor ice between the tires and theroad, creating less traction or grip.

Wet ice can occur at about 0°C(32°F) when freezing rain begins tofall, resulting in even less traction.Avoid driving on wet ice or infreezing rain until roads can betreated with salt or sand.

Drive with caution, whatever thecondition. Accelerate gently sotraction is not lost. Accelerating tooquickly causes the wheels to spinand makes the surface under thetires slick, so there is even lesstraction.

Try not to break the fragile traction.If you accelerate too fast, the drivewheels will spin and polish thesurface under the tires even more.

Traction Control should be turnedon. See Traction Control/ElectronicStability Control on page 9-34.

The Antilock Brake System (ABS)improves vehicle stability duringhard stops on slippery roads, butapply the brakes sooner than whenon dry pavement. See AntilockBrake System (ABS) on page 9-31.

Allow greater following distance onany slippery road and watch forslippery spots. Icy patches canoccur on otherwise clear roads inshaded areas. The surface of acurve or an overpass can remain icywhen the surrounding roads areclear. Avoid sudden steeringmaneuvers and braking whileon ice.

Turn off cruise control on slipperysurfaces.

Blizzard Conditions

Being stuck in snow can be aserious situation. Stay with thevehicle unless there is help nearby.If possible, use RoadsideAssistance. See RoadsideAssistance Program on page 13-5.To get help and keep everyone inthe vehicle safe:. Turn on the hazard warning

flashers.. Tie a red cloth to an outside

mirror.

{ Warning

Snow can trap engine exhaustunder the vehicle. This maycause exhaust gases to getinside. Engine exhaust containscarbon monoxide (CO) whichcannot be seen or smelled. It cancause unconsciousness and evendeath.

If the vehicle is stuck in the snow:. Clear away snow from aroundthe base of your vehicle,especially any that is blockingthe exhaust pipe.

. Check again from time totime to be sure snow doesnot collect there.

. Open a window about 5 cm(2 in) on the side of thevehicle that is away from thewind to bring in fresh air.

(Continued)

Warning (Continued)

. Fully open the air outlets onor under the instrumentpanel.

. Adjust the climate controlsystem to a setting thatcirculates the air inside thevehicle and set the fan speedto the highest setting. See“Climate Control Systems”.

For more information aboutcarbon monoxide, see EngineExhaust on page 9-26.

To save fuel, run the engine for onlyshort periods as needed to warmthe vehicle and then shut the engineoff and close the window most ofthe way to save heat. Repeat thisuntil help arrives but only when youfeel really uncomfortable from thecold. Moving about to keep warmalso helps.

If it takes some time for help toarrive, now and then when you runthe engine, push the acceleratorpedal slightly so the engine runsfaster than the idle speed. Thiskeeps the battery charged to restartthe vehicle and to signal for helpwith the headlamps. Do this as littleas possible to save fuel.

If the Vehicle Is StuckSlowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.

If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. See TractionControl/Electronic Stability Controlon page 9-34.

vehicle can overheat, causing anengine compartment fire or otherdamage. Spin the wheels as littleas possible and avoid goingabove 56 km/h (35 mph).

Rocking the Vehicle to Getit Out

Turn the steering wheel left andright to clear the area around thefront wheels. Turn off any tractionsystem. Shift back and forthbetween R (Reverse) and a lowforward gear, spinning the wheelsas little as possible. To preventtransmission wear, wait until thewheels stop spinning before shiftinggears. Release the acceleratorpedal while shifting, and presslightly on the accelerator pedalwhen the transmission is in gear.

Slowly spinning the wheels in theforward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. If thevehicle does need to be towed out,see Towing the Vehicle onpage 10-81.

Vehicle Load LimitsIt is very important to know howmuch weight the vehicle cancarry. This weight is called thevehicle capacity weight andincludes the weight of alloccupants, cargo, and allnonfactory-installed options.Two labels on the vehicle showhow much weight it mayproperly carry, the Tire andLoading Information label andthe Certification label.

{ Warning

Do not load the vehicle anyheavier than the GrossVehicle Weight Rating(GVWR), or either themaximum front or rear GrossAxle Weight Rating (GAWR).This can cause systems tobreak and change the way thevehicle handles. This couldcause loss of control and acrash. Overloading can alsoshorten the life of the vehicle.

Brakes

Antilock BrakeSystem (ABS)This vehicle has ABS, an advancedelectronic braking system that helpsprevent a braking skid.

When the vehicle begins to driveaway, ABS checks itself.A momentary motor or clicking noisemight be heard while this test isgoing on, and it might even benoticed that the brake pedal movesa little. This is normal.

If there is a problem with ABS, thiswarning light stays on. See AntilockBrake System (ABS) Warning Lighton page 5-20.

If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses the wheels areslowing down. If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.

ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.

As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.

Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehicle

suddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.

Using ABS

Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You may hear the ABSpump or motor operating and feelthe brake pedal pulsate. This isnormal.

Braking in Emergencies

ABS allows you to steer and brakeat the same time. In manyemergencies, steering can helpmore than even the very bestbraking.

Parking Brake

The Electric Parking Brake (EPB)switch is on the center console. TheEPB can always be activated, evenif the ignition is off. To preventdraining the battery, avoid repeatedcycles of the EPB when the engineis not running.

The system has a red parking brakestatus light and an amber parkingbrake warning light. See ElectricParking Brake Light on page 5-19and Service Electric Parking BrakeLight on page 5-19. There are also

parking brake-related DriverInformation Center (DIC) messages.See Brake System Messages onpage 5-34. In case of insufficientelectrical power, the EPB cannot beapplied or released.

Before leaving the vehicle, checkthe red parking brake status light toensure that the parking brake isapplied.

EPB Apply

To apply the EPB:

1. Be sure the vehicle is at acomplete stop.

2. Lift up the EPB switchmomentarily.

The red parking brake status lightwill flash and then stay on once theEPB is fully applied. If the redparking brake status light flashescontinuously, then the EPB is onlypartially applied or there is aproblem with the EPB. A DICmessage will display. Release theEPB and try to apply it again. If thelight does not come on, or keeps

flashing, have the vehicle serviced.Do not drive the vehicle if the redparking brake status light is flashing.See your dealer. See ElectricParking Brake Light on page 5-19.

If the amber parking brake warninglight is on, lift up on the EPB switchand hold it up. Continue to hold theswitch until the red parking brakestatus light remains on. If the amberparking brake warning light is on,see your dealer.

If the EPB is applied while thevehicle is moving, the vehicle willdecelerate as long as the switch isheld up. If the switch is held up untilthe vehicle comes to a stop, theEPB will remain applied.

The vehicle may automatically applythe EPB in some situations whenthe vehicle is not moving. This isnormal, and is done to periodicallycheck the correct operation of theEPB system.

If the EPB fails to apply, the rearwheels should be blocked toprevent vehicle movement.

If parking on a hill, or if the vehicleis pulling a trailer, see DrivingCharacteristics and Towing Tips onpage 9-63.

Brake AssistThe Brake Assist feature isdesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brake

control module to supplement thepower brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.

Hill Start Assist (HSA)This vehicle has an HSA feature,which may be useful when thevehicle is stopped on a grade. Thisfeature is designed to prevent thevehicle from rolling, either forward orrearward, during vehicle drive off.

After the driver completely stopsand holds the vehicle in a completestandstill on a grade, HSA will beautomatically activated. During thetransition period between when thedriver releases the brake pedal andstarts to accelerate to drive off on agrade, HSA holds the brakingpressure for a maximum oftwo seconds to ensure that there isno rolling. The brakes willautomatically release when theaccelerator pedal is applied withinthe two-second window. It will notactivate if the vehicle is in a drivegear and facing downhill, or if thevehicle is facing uphill and inR (Reverse).

Ride Control Systems

Traction Control/Electronic StabilityControl

System Operation

The vehicle has a Traction ControlSystem (TCS) and StabiliTrak®, anelectronic stability control system.These systems help limit wheel slipand assist the driver in maintainingcontrol, especially on slippery roadconditions.

TCS activates if it senses that anyof the drive wheels are spinning orbeginning to lose traction. When thishappens, TCS applies the brakes tothe spinning wheels and reducesengine power to limit wheel spin.

StabiliTrak activates when thevehicle senses a difference betweenthe intended path and the directionthe vehicle is actually traveling.StabiliTrak selectively appliesbraking pressure to any one of the

vehicle wheel brakes to assist thedriver in keeping the vehicle on theintended path.

If cruise control is being used andtraction control or StabiliTrak beginsto limit wheel spin, cruise control willdisengage. Cruise control may beturned back on when roadconditions allow.

Both systems come onautomatically when the vehicle isstarted and begins to move. Thesystems may be heard or felt whilethey are operating or whileperforming diagnostic checks. Thisis normal and does not mean thereis a problem with the vehicle.

It is recommended to leave bothsystems on for normal drivingconditions, but it may be necessaryto turn TCS off if the vehicle getsstuck in sand, mud, ice, or snow.See If the Vehicle Is Stuck onpage 9-9 and “Turning the SystemsOff and On” later in this section.

Limited-Slip DifferentialVehicles with a limited-slipdifferential can give more traction onsnow, mud, ice, sand, or gravel.It works like a standard differentialmost of the time, but when traction

is low, this feature allows the drivewheel with the most traction tomove the vehicle.

Selective Ride ControlThe vehicle may have a ride controlsystem called Selective RideControl. The system provides thefollowing performance benefits:. Reduced Impact Harshness. Improved Road Isolation. Improved High-Speed Stability. Improved Handling Response. Better Control of Body Ride

Motions

To switch from TOUR to SPORTmode, move the shift lever to theM/S (Manual/Sport) position.

TOUR: Use for normal city andhighway driving. This settingprovides a smooth, soft ride.

SPORT: Use where road conditionsor personal preference demandmore control. This setting providesmore “feel,” or response to roadconditions through increasedsteering effort and suspensiontuning.

The setting can be changed at anytime. Based on road conditions,steering wheel angle, and vehiclespeed, the system automaticallyadjusts to provide the best handlingwhile providing a smooth ride. TheTOUR and SPORT modes will feelsimilar on a smooth road.

Assistance Systems forDrivingIf equipped, when driving thevehicle forward, Forward CollisionAlert (FCA), Lane DepartureWarning (LDW), Lane Change Alert(LCA), and/or the Active EmergencyBraking System can help to avoid acrash or reduce crash damage.

Forward Collision Alert(FCA) SystemThe FCA system may help to avoidor reduce the harm caused byfront-end crashes. FCA provides aflashing red alert on the windshield,and beeps or pulses the Safety AlertSeat when approaching a vehicledirectly ahead too quickly. FCA alsoprovides a visual alert if followinganother vehicle much too closely.

FCA detects vehicles within adistance of approximately 60 m(197 ft) and operates at speedsabove 40 km/h (25 mph). If thevehicle has Adaptive Cruise Control

(ACC), it can detect vehicles todistances of approximately 110 m(360 ft). See Adaptive CruiseControl on page 9-39.

{ Warning

FCA is a warning system anddoes not apply the brakes. Whenapproaching a slower-moving orstopped vehicle ahead too rapidly,or when following a vehicle tooclosely, FCA may not provide awarning with enough time to helpavoid a crash. FCA does not warnof pedestrians, animals, signs,guardrails, bridges, constructionbarrels, or other objects. Be readyto take action and apply thebrakes. For more information, seeDefensive Driving on page 9-3.

FCA can be disabled throughvehicle personalization. See the“Auto Collision Preparation” portion

Detecting the Vehicle Ahead

FCA warnings will not occur unlessthe FCA system detects a vehicleahead. The vehicle-ahead indicatorwill display green when a vehicle isdetected in front. Vehicles may notbe detected on curves, highway exitramps, or hills; or due to poorvisibility. FCA will not detect anothervehicle ahead until it is completelyin the driving lane.

{ Warning

FCA does not provide a warningto help avoid a crash, unless itdetects a vehicle. FCA may notdetect a vehicle ahead if the FCAsensor is blocked by dirt, snow,or ice, or if the windshield isdamaged. It may also not detect avehicle on winding or hilly roads,or in conditions that can limitvisibility such as fog, rain,or snow, or if the headlamps orwindshield are not cleaned or inproper condition. Keep thewindshield, headlamps, and FCAsensors clean and in good repair.

Collision Alert

When your vehicle approachesanother vehicle too rapidly, the redcollision alert symbol on the HUD,will flash on the windshield. Eithereight beeps will sound from thefront, or both sides of the SafetyAlert Seat will pulse five times.

Tailgating Alert

The vehicle-ahead indicator willdisplay amber when you arefollowing a vehicle ahead much tooclosely.

Selecting the Alert Timing

The Collision Alert control is on thesteering wheel. Press[ or3 toset the alert timing. The first buttonpress shows the current setting onthe DIC. Additional button presseswill change this setting. The chosensetting will remain until it is changedand will affect the timing of both theCollision Alert and the TailgatingAlert features. The timing of bothalerts will vary based on vehiclespeed. The faster the vehicle speed,the farther away the alert will occur.Consider traffic and weather

conditions when selecting the alerttiming. The range of selectable alerttiming may not be appropriate for alldrivers and driving conditions.

Changing the FCA timing settingautomatically changes the followinggap setting (Far, Medium, or Near)for the Adaptive Cruise Control(ACC) feature.

Unnecessary Alerts

FCA may provide unnecessaryalerts for turning vehicles, vehiclesin other lanes, objects that are notvehicles, or shadows. These alertsare normal operation and thevehicle does not need service.

Cleaning the System

If the FCA system does not seem tooperate properly, cleaning theoutside of the windshield in front ofthe camera sensor and the front ofthe vehicle may correct the issue.

Active EmergencyBraking SystemIf the vehicle has Adaptive CruiseControl (ACC) it also has the ActiveEmergency Braking System, whichincludes the Automatic CollisionPreparation (ACP) System.

Automatic CollisionPreparation (ACP) System

ACP may help reduce crashdamage by applying the vehicle’sbrake system and has a detectionrange of approximately 60 m(197 ft). Braking can only occur if avehicle is detected ahead. This isshown by the FCA vehicle-aheadindicator being lit. See ForwardCollision Alert (FCA) System onpage 9-50.

{ Warning

ACP is an emergency crashpreparation feature and is notdesigned to avoid crashes. Donot rely on ACP to brake thevehicle.

ACP may not:. Respond to stopped vehicles,pedestrians, or animals.

. Detect a vehicle ahead onwinding or hilly roads.

. Detect a stopped orslow-moving vehicle or otherobject ahead.

. Detect a vehicle whenweather limits visibility, suchas in fog, rain, or snow. Inthese situations, ACP sensorperformance is limited.

(Continued)

Warning (Continued)

Complete attention is alwaysrequired while driving, and youshould be ready to take actionand apply the brakes and/or steerthe vehicle to avoid crashes.

Brake Preparation

When quickly approaching a vehicleahead, Brake Preparation reducesbrake response time by having thebrake system prepared for driverbraking to occur more rapidly.

Automatic Braking

In some imminent front-end crashsituations, if the driver has notapplied the brakes, AutomaticBraking applies the brakes to helpreduce crash damage. It may evenhelp avoid some very low speedcrashes.

Automatic Braking may slow thevehicle to a complete stop to try toavoid a potential crash. The vehicle

will only hold at a stop briefly. A firmpress of the accelerator pedal willalso release Automatic Braking.

{ Warning

Automatic Braking mayautomatically brake the vehicle insituations where it may beunnecessary. It could respond toa turning vehicle ahead,guardrails, signs, and othernon-moving objects. This couldbe uncomfortable and startling. Tooverride Automatic Braking, firmlypress the accelerator pedal, if it issafe to do so.

Automatic Braking can be disabledor reduced through vehiclepersonalization. See the “AutoCollision Preparation” portion of“Collision/Detection Systems” underVehicle Personalization onpage 5-43.

and 2m (6 ft) off the ground. Theside blind zone warning area startsat approximately the middle of thevehicle and goes back 5 m (16 ft).Drivers are also warned of vehiclesrapidly approaching from up to70 m (230 ft) behind the vehicle.

How the System Works

The LCA symbol lights up in theside mirrors when the systemdetects a vehicle in the next laneover that is in the side blind zone orrapidly approaching from behind.A lit LCA symbol indicates it may beunsafe to change lanes. Beforemaking a lane change, check theLCA display, check mirrors, glanceover your shoulder, and use the turnsignals.

Left Side MirrorDisplay

Right Side MirrorDisplay

When the vehicle is started, bothoutside mirror LCA displays willbriefly come on to indicate thesystem is operating. When thevehicle is moving forward, the left-or right-side mirror display will lightup if a vehicle is detected in thenext lane over in that blind zone orrapidly approaching that zone. If theturn signal is activated in the samedirection as a detected vehicle, thisdisplay will flash as an extrawarning not to change lanes.

LCA can be disabled throughvehicle personalization. See“Collision/Detection Systems” underVehicle Personalization onpage 5-43. If LCA is disabled by thedriver, the LCA mirror displays willnot light up.

When the System Does NotSeem to Work Properly

The LCA system requires somedriving for the system to calibrate tomaximum performance. Thiscalibration may occur more quickly ifthe vehicle is driving on a straight

highway road with traffic androadside objects (e.g., guardrails,barriers).

LCA displays may not come onwhen passing a vehicle quickly orwhen towing a trailer. The LCAdetection zones that extend backfrom the side of the vehicle do notmove further back when a trailer istowed. Use caution while changinglanes when towing a trailer. LCAmay alert to objects attached to thevehicle, such as a trailer, bicycle,or object extending out to either sideof the vehicle. Attached objects mayalso interfere with the detection ofvehicles. This is normal systemoperation; the vehicle does not needservice.

LCA may not always alert the driverto vehicles in the next lane over,especially in wet conditions or whendriving on sharp curves. The systemdoes not need to be serviced. Thesystem may light up due toguardrails, signs, trees, shrubs, and

Lane DepartureWarning (LDW)If equipped, LDW may help avoidcrashes due to unintentional lanedepartures. It may provide awarning if the vehicle is crossing adetected lane marking without usinga turn signal. LDW uses a camerasensor to detect the lane markings.It only operates at speeds of56 km/h (35 mph) or greater.

When the vehicle crosses adetected lane marking, the LDWindicator will flash and either threebeeps will be sounded from the leftor right side, or three Safety AlertSeat pulses will occur on the left orright side of the seat, depending onthe lane departure direction. LDWwill not warn if the turn signal is onin the departure direction, or if asharp maneuver is made.

{ Warning

The LDW system is an aid to helpthe vehicle stay in the drivinglane. It does not steer the vehicle.The LDW system may not:

. Provide enough time to avoida crash.

. Detect lane markings underbad weather conditions or ifthe windshield is dirty.

. Detect lane markings and willnot detect road edges.

. Warn that the vehicle iscrossing a lane marking if thesystem does not detect thelane marking.

If LDW only detects lanemarkings on one side of the road,it will only warn you whendeparting the lane on the sidewhere it has detected a lanemarker. Even with LDW, alwayskeep your attention on the road

FuelUse of the recommended fuel is animportant part of the propermaintenance of this vehicle. Whendriving in the U.S., to help keep theengine clean and maintain optimumvehicle performance, werecommend using TOP TIERDetergent Gasolines. Seewww.toptiergas.com for a list of TOPTIER Detergent Gasolines.

If the vehicle has a yellow fuel cap,E85 or FlexFuel can be used in thevehicle. See E85 or FlexFuel onpage 9-60.

Recommended FuelUse regular unleaded gasoline witha posted octane rating of 87 orhigher. If the octane rating is lessthan 87, an audible knocking noisemay be heard. If this occurs, use agasoline rated at 87 octane orhigher as soon as possible. If heavyknocking is heard when usinggasoline with a higher octane rating,the engine needs service.

Use of Seasonal Fuels

Use summer and winter fuels in theappropriate season. Driving orstarting could be affected if theincorrect fuel is used. Drive thevehicle with the engine running untilthe fuel is a half tank or less, thenrefuel with the current seasonal fuel.

Prohibited Fuels

Gasolines containing oxygenates,such as ethers and ethanol, as wellas reformulated gasolines areavailable in some cities. If thesegasolines comply with thepreviously described specification,then they are acceptable to use.However, E85 and other fuelscontaining more than 15% ethanolmust be used only in FlexFuelvehicles.

{ Caution

Do not use fuel containingmethanol. It can corrode metalparts in the fuel system and alsodamage plastic and rubber parts.That damage would not becovered under the vehiclewarranty.

Some gasolines that are notreformulated for low emissions cancontain an octane-enhancingadditive called

methylcyclopentadienyl manganesetricarbonyl (MMT). Do not usegasolines with MMT as they canreduce spark plug life and affectemission control systemperformance. The malfunctionindicator lamp may turn on. If thisoccurs, see your dealer for service.

Gasoline SpecificationsAt a minimum, gasoline should meetASTM specification D 4814. Somegasolines contain anoctane-enhancing additive calledmethylcyclopentadienyl manganesetricarbonyl (MMT). We recommendagainst the use of gasolinescontaining MMT. See “ProhibitedFuels" in Recommended Fuel onpage 9-58.

California FuelRequirementsIf the vehicle is certified to meetCalifornia Emissions Standards, it isdesigned to operate on fuels thatmeet California specifications. See

the underhood emission controllabel. If this fuel is not available instates adopting California EmissionsStandards, the vehicle will operatesatisfactorily on fuels meetingfederal specifications, but emissioncontrol system performance mightbe affected. The malfunctionindicator lamp could turn on and thevehicle may not pass a smog-checktest. See Malfunction IndicatorLamp on page 5-16. If this occurs,return to your authorized dealer fordiagnosis. If it is determined that thecondition is caused by the type offuel used, repairs may not becovered by the vehicle warranty.

recommended. Costly repairscaused by use of improper fuelwould not be covered by the vehiclewarranty.

Fuel AdditivesTo keep fuel systems clean, TOPTIER Detergent Gasoline isrecommended. See Fuel onpage 9-58.

If TOP TIER Detergent Gasoline isnot available, one bottle of FuelSystem Treatment PLUS, partnumber 88861013, added to the fueltank at every engine oil change, canhelp. Fuel System Treatment PLUSis the only gasoline additiverecommended by General Motors.It is available at your dealer.

Do not use additives with E85 orFlexFuel.

E85 or FlexFuelVehicles with a yellow fuel cap canuse either unleaded gasoline or fuelcontaining up to 85% ethanol (E85).

All other vehicles should use onlythe unleaded gasoline as describedin Recommended Fuel onpage 9-58.

The use of E85 or FlexFuel isencouraged when the vehicle isdesigned to use it. E85 or FlexFuelis made from renewable sources.

To help locate fuel stations thatcarry E85 or FlexFuel, the U.S.Department of Energy has analternative fuel website. Seewww.afdc.energy.gov/afdc/locator/stations.

E85 or FlexFuel should meet ASTMSpecification D 5798 or CAN/CGSB–3.512 in Canada. Do not usethe fuel if the ethanol content isgreater than 85%. Fuel mixtures thatdo not meet ASTM or CGSBspecifications can affect driveabilityand could cause the malfunctionindicator lamp to come on.

The starting characteristics of E85or FlexFuel make it unsuitable foruse when temperatures fall below−18°C (0°F). Use gasoline or addgasoline to the E85 or FlexFuel.

Because E85 or FlexFuel has lessenergy per liter (gallon) thangasoline, the vehicle will need to berefilled more often. See Filling theTank on page 9-61.

{ Caution

Some additives are notcompatible with E85 or FlexFueland can harm the vehicle's fuelsystem. Do not add anything toE85 or FlexFuel. Damage causedby additives would not be coveredby the vehicle warranty.

and local laws that apply totrailer towing.

. Do not tow a trailer during thefirst 800 km (500 mi) to preventdamage to the engine, axle,or other parts.

. Then during the first 800 km(500 mi) of trailer towing, do notdrive over 80 km/h (50 mph) anddo not make starts at full throttle.

. Vehicles can tow in D (Drive).Shift the transmission to a lowergear if the transmission shiftstoo often under heavy loads and/or hilly conditions.

. Do not use Adaptive CruiseControl when towing.

. The Automatic CollisionPreparation System should beset to Off when towing. SeeActive Emergency BrakingSystem on page 9-52.

. Turn off Park Assist whentowing.

9-64 Driving and Operating

Towing a trailer requires a certainamount of experience. Thecombination you are driving islonger and not as responsive as thevehicle itself. Get acquainted withthe handling and braking of the rigbefore setting out for the open road.

Before starting, check all trailer hitchparts and attachments, safetychains, electrical connectors, lamps,tires, and mirrors. If the trailer haselectric brakes, start thecombination moving and then applythe trailer brake controller by handto be sure the brakes work.

During the trip, check occasionallyto be sure that the load is secureand the lamps and any trailerbrakes still work.

Following Distance

Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavybraking and sudden turns.

Passing

More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.

Backing Up

Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.

Making Turns

{ Caution

Making very sharp turns whiletrailering could cause the trailer tocome in contact with the vehicle.

(Continued)

Caution (Continued)

The vehicle could be damaged.Avoid making very sharp turnswhile trailering.

When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.

If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.

Driving on Grades

Reduce speed and shift to a lowergear before starting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.

Driving and Operating 9-65

Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.

When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil ata lower temperature than at normalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with theautomatic transmission in P (Park)for a few minutes before turning theengine off. If the overheat warningcomes on, see Engine Overheatingon page 10-21.

Parking on Hills

{ Warning

Parking the vehicle on a hill withthe trailer attached can bedangerous. If something goeswrong, the rig could start to move.People can be injured, and boththe vehicle and the trailer can bedamaged. When possible, alwayspark the rig on a flat surface.

If parking the rig on a hill:

1. Press the brake pedal, but donot shift into P (Park) yet. Turnthe wheels into the curb if facingdownhill or into traffic if facinguphill.

2. Have someone place chocksunder the trailer wheels.

3. When the wheel chocks are inplace, release the regular brakesuntil the chocks absorb the load.

4. Reapply the brake pedal. Thenapply the parking brake and shiftinto P (Park).

5. Release the brake pedal.

Leaving After Parking on a Hill

1. Apply and hold the brake pedal.

2. Start the engine.

3. Shift into a gear.

4. Release the parking brake.

5. Let up on the brake pedal.

6. Drive slowly until the trailer isclear of the chocks.

7. Stop and have someone pick upand store the chocks.

Maintenance when TrailerTowing

The vehicle needs service moreoften when pulling a trailer. SeeMaintenance Schedule onpage 11-2. Things that areespecially important in traileroperation are automatictransmission fluid, engine oil, axle

lubricant, belts, cooling system, andbrake system. It is a good idea toinspect these before and duringthe trip.

Check periodically to see that allhitch nuts and bolts are tight.

Trailer Towing (ExcepteAssist)Before pulling a trailer, threeimportant considerations have to dowith weight:. Weight of the trailer.. Weight of the trailer tongue.. Total weight on your vehicle's

tires.

Weight of the Trailer

How heavy can a trailer safely be?

It should never weigh more than454 kg (1,000 lb). But even that canbe too heavy.

It depends on how the rig is used.For example, speed, altitude, roadgrades, outside temperature, and

how much the vehicle is used to pulla trailer are all important. It candepend on any special equipmenton the vehicle, and the amount oftongue weight the vehicle can carry.See “Weight of the Trailer Tongue”later in this section.

Maximum trailer weight is calculatedassuming only the driver is in thetow vehicle and it has all therequired trailering equipment. Theweight of additional optionalequipment, passengers, and cargoin the tow vehicle must besubtracted from the maximum trailerweight.

Ask your dealer for traileringinformation or advice, or write us atour Customer Assistance Offices.See Customer Assistance Officeson page 13-3.

Weight of the Trailer Tongue

The tongue load (1) of any trailer isan important weight to measurebecause it affects the total grossweight of the vehicle. The GrossVehicle Weight (GVW) includes the

curb weight of the vehicle, anycargo carried in it, and the peoplewho will be riding in the vehicle.If there are a lot of options,equipment, passengers, or cargo inthe vehicle, it will reduce the tongueweight the vehicle can carry, whichwill also reduce the trailer weight thevehicle can tow. If towing a trailer,the tongue load must be added tothe GVW because the vehicle willbe carrying that weight, too. SeeVehicle Load Limits on page 9-10.

Page 247: 2014 Buick LaCrosse Owner Manual M · Buick LaCrosse Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- Black plate (2,1) 6043609) - 2014 - 2nd Edition - 10/17/13 2014 Buick LaCrosse

Driving and Operating 9-67

The trailer tongue (1) should weigh10 percent of the total loaded trailerweight (2).

After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.

Total Weight on Your Vehicle'sTires

Be sure the vehicle's tires areinflated to the upper limit for coldtires. These numbers can be foundon the Tire and Loading Informationlabel. See Vehicle Load Limits onpage 9-10. Make sure not to go overthe GVW limit for the vehicle,including the weight of the trailertongue.

Trailer Towing (eAssist)The vehicle is neither designed norintended to tow a trailer.

Towing Equipment

Hitches

Use the correct hitch equipment.See your dealer or a hitch dealer forassistance.. The rear bumper on the vehicle

is not intended for hitches. Donot attach rental hitches or otherbumper-type hitches to it. Useonly a frame-mounted hitch thatdoes not attach to the bumper.

. Will any holes be made in thebody of the vehicle when thetrailer hitch is installed? If so,seal the holes when the hitch isremoved. If the holes are notsealed, dirt, water, and deadlycarbon monoxide (CO) from theexhaust can get into the vehicle.See Engine Exhaust onpage 9-26.

Safety Chains

Always attach chains between thevehicle and the trailer. Cross thesafety chains under the tongue ofthe trailer to help prevent the tonguefrom contacting the road if itbecomes separated from the hitch.Leave enough slack so the rig canturn. Never allow safety chains todrag on the ground.

Trailer Brakes

Does the trailer have its ownbrakes? Be sure to read and followthe instructions for the trailer brakesso they are installed, adjusted, andmaintained properly.

Because the vehicle has antilockbrakes, do not tap into the vehicle'sbrake system. If this is done, bothbrake systems will not work well,or at all.

Engine OilTo ensure proper engineperformance and long life, carefulattention must be paid to engine oil.Following these simple, butimportant steps will help protectyour investment:. Always use engine oil approved

to the proper specification and ofthe proper viscosity grade. See“Selecting the Right Engine Oil”in this section.

. Check the engine oil levelregularly and maintain theproper oil level. See “CheckingEngine Oil” and “When to AddEngine Oil” in this section.

. Change the engine oil at theappropriate time. See Engine OilLife System on page 10-13.

. Always dispose of engine oilproperly. See “What to Do withUsed Oil” in this section.

Checking Engine Oil

It is a good idea to check the engineoil level at each fuel fill. In order toget an accurate reading, the vehiclemust be on level ground. Theengine oil dipstick handle is a loop.See Engine Compartment Overviewon page 10-6 for the location of theengine oil dipstick.

Obtaining an accurate oil levelreading is essential:

1. If the engine has been runningrecently, turn off the engine andallow several minutes for the oilto drain back into the oil pan.Checking the oil level too soonafter engine shutoff will notprovide an accurate oil levelreading.

{ Warning

The engine oil dipstick handlemay be hot; it could burn you.Use a towel or glove to touch thedipstick handle.

2. Pull out the dipstick and clean itwith a paper towel or cloth, thenpush it back in all the way.Remove it again, keeping the tipdown, and check the level.

When to Add Engine Oil

2.4L L4 Engine

3.6L V6 Engine

If the oil is below the cross-hatchedarea at the tip of the dipstick, add1 L (1 qt) of the recommended oiland then recheck the level. See“Selecting the Right Engine Oil” inthis section for an explanation of

what kind of oil to use. For engineoil crankcase capacity, seeCapacities and Specifications onpage 12-2.

{ Caution

Do not add too much oil. Oillevels above or below theacceptable operating rangeshown on the dipstick are harmfulto the engine. If you find that youhave an oil level above theoperating range, i.e., the enginehas so much oil that the oil levelgets above the cross-hatchedarea that shows the properoperating range, the engine couldbe damaged. You should drainout the excess oil or limit drivingof the vehicle and seek a serviceprofessional to remove theexcess amount of oil.

See Engine Compartment Overviewon page 10-6 for the location of theengine oil fill cap.

Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.

Selecting the Right Engine Oil

Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.See Recommended Fluids andLubricants on page 11-12.

Specification

Use and ask for licensed engine oilswith the dexos1® approvedcertification mark. Engine oilsmeeting the requirements for thevehicle should have the dexos1approved certification mark. Thiscertification mark indicates that theoil has been approved to the dexos1specification.

Page 261: 2014 Buick LaCrosse Owner Manual M · Buick LaCrosse Owner Manual (GMNA-Localizing-U.S./Canada/Mexico- Black plate (2,1) 6043609) - 2014 - 2nd Edition - 10/17/13 2014 Buick LaCrosse

Vehicle Care 10-13

{ Caution

Failure to use the recommendedengine oil can result in enginedamage not covered by thevehicle warranty. Check with yourdealer or service provider onwhether the oil is approved to thedexos1 specification.

Viscosity Grade

SAE 5W-30 is the best viscositygrade for the vehicle. Do not useother viscosity grade oils such asSAE 10W-30, 10W-40, or 20W-50.

Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below −29°C(−20°F), an SAE 0W-30 oil may beused. An oil of this viscosity grade

will provide easier cold starting forthe engine at extremely lowtemperatures. When selecting an oilof the appropriate viscosity grade,always select an oil of the correctspecification. See “Specification”earlier in this section for moreinformation.

Engine Oil Additives/EngineOil Flushes

Do not add anything to the oil. Therecommended oils with the dexosspecification and displaying thedexos certification mark are all thatis needed for good performance andengine protection.

Engine oil system flushes are notrecommended and could causeengine damage not covered by thevehicle warranty.

What to Do with Used Oil

Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean your

skin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.

Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all the oilfrom the filter before disposal. Neverdispose of oil by putting it in thetrash or pouring it on the ground,into sewers, or into streams orbodies of water. Recycle it by takingit to a place that collects used oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is basedon a combination of factors whichinclude engine revolutions, enginetemperature, and miles driven.Based on driving conditions, themileage at which an oil change isindicated can vary considerably. For

the oil life system to work properly,the system must be reset every timethe oil is changed.

When the system has calculatedthat oil life has been diminished, itindicates that an oil change isnecessary. A CHANGE ENGINEOIL SOON message comes on. SeeEngine Oil Messages on page 5-37.Change the oil as soon as possiblewithin the next 1 000 km (600 mi).It is possible that, if driving underthe best conditions, the oil lifesystem might indicate that an oilchange is not necessary for up to ayear. The engine oil and filter mustbe changed at least once a yearand at this time the system must bereset. Your dealer has trainedservice people who will perform thiswork and reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.

If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)

since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.

How to Reset the Engine OilLife System

Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. To reset thesystem:

1. Using the DIC controls on theright side of the steering wheel,display REMAINING OIL LIFEon the DIC. See DriverInformation Center (DIC) onpage 5-27. When remaining oillife is low, the CHANGEENGINE OIL SOON messagewill appear on the display. SeeEngine Oil Messages onpage 5-37.

2. Press V on the DIC controls andhold down for a few seconds toclear the CHANGE ENGINE OILSOON message and reset theoil life at 100%.

Be careful not to reset the oil lifedisplay accidentally at any timeother than after the oil ischanged. It cannot be resetaccurately until the next oilchange.

The system is reset when theCHANGE ENGINE OIL SOONmessage is off.

If the CHANGE ENGINE OIL SOONmessage comes back on when thevehicle is started, the engine oil lifesystem has not been reset. Repeatthe procedure.

heard all the time when the vehicleis moving, except when applying thebrake pedal firmly.

{ Warning

The brake wear warning soundmeans that soon the brakes willnot work well. That could lead toa crash. When the brake wearwarning sound is heard, have thevehicle serviced.

{ Caution

Continuing to drive with worn-outbrake pads could result in costlybrake repair.

Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.

Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts in theproper sequence to torquespecifications. See Capacities andSpecifications on page 12-2.

Brake pads should be replaced ascomplete sets.

Brake Pedal Travel

See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be a signthat brake service might berequired.

Brake Adjustment

Every time the brakes are applied,with or without the vehicle moving,the brakes adjust for wear.

Replacing Brake System Parts

The braking system on a vehicle iscomplex. Its many parts have to beof top quality and work well together

if the vehicle is to have really goodbraking. The vehicle was designedand tested with top-quality brakeparts. When parts of the brakingsystem are replaced, be sure to getnew, approved replacement parts.If this is not done, the brakes mightnot work properly. For example,installing disc brake pads that arewrong for the vehicle, can changethe balance between the front andrear brakes — for the worse. Thebraking performance expected canchange in many other ways if thewrong replacement brake parts areinstalled.

Brake Fluid

The brake master cylinder reservoiris filled with DOT 3 brake fluid asindicated on the reservoir cap. See

10-26 Vehicle Care

Engine Compartment Overview onpage 10-6 for the location of thereservoir.

There are only two reasons why thebrake fluid level in the reservoirmight go down:. The brake fluid level goes down

because of normal brake liningwear. When new linings areinstalled, the fluid level goesback up.

. A fluid leak in the brakehydraulic system can also causea low fluid level. Have the brakehydraulic system fixed, since aleak means that sooner or laterthe brakes will not work well.

Do not top off the brake fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove brake fluid,as necessary, only when work isdone on the brake hydraulic system.

{ Warning

If too much brake fluid is added, itcan spill on the engine and burn,if the engine is hot enough. Youor others could be burned, andthe vehicle could be damaged.Add brake fluid only when work isdone on the brake hydraulicsystem.

When the brake fluid falls to a lowlevel, the brake warning light comeson. See Brake System WarningLight on page 5-19.

What to Add

Use only new DOT 3 brake fluidfrom a sealed container. SeeRecommended Fluids andLubricants on page 11-12.

Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it. Thishelps keep dirt from entering thereservoir.

{ Warning

With the wrong kind of fluid in thebrake hydraulic system, thebrakes might not work well. Thiscould cause a crash. Always usethe proper brake fluid.

{ Caution

. Using the wrong fluid canbadly damage brakehydraulic system parts. Forexample, just a few drops ofmineral-based oil, such asengine oil, in the brakehydraulic system can damagebrake hydraulic system partsso badly that they will have tobe replaced. Do not letsomeone put in the wrongkind of fluid.

Electrical System

High Voltage Devices andWiring

{ Warning

Exposure to high voltage cancause shock, burns, and evendeath. The high voltagecomponents in the vehicle canonly be serviced by technicianswith special training.

High voltage components areidentified by labels. Do notremove, open, take apart,or modify these components.High voltage cable or wiring hasorange covering. Do not probe,tamper with, cut, or modify highvoltage cable or wiring.

Electrical SystemOverloadThe vehicle has fuses and circuitbreakers to protect against anelectrical system overload.

When the current electrical load istoo heavy, the circuit breaker opensand closes, protecting the circuituntil the current load returns tonormal or the problem is fixed. Thisgreatly reduces the chance of circuitoverload and fire caused byelectrical problems.

Fuses and circuit breakers protectpower devices in the vehicle.

Replace a bad fuse with a new oneof the identical size and rating.

If there is a problem on the road anda fuse needs to be replaced, thesame amperage fuse can beborrowed. Choose some feature ofthe vehicle that is not needed to useand replace it as soon as possible.

Headlamp Wiring

An electrical overload may causethe lamps to go on and off, or insome cases to remain off. Have theheadlamp wiring checked right awayif the lamps go on and off orremain off.

Windshield Wipers

If the wiper motor overheats due toheavy snow or ice, the windshieldwipers will stop until the motor coolsand will then restart.

Although the circuit is protectedfrom electrical overload, overloaddue to heavy snow or ice maycause wiper linkage damage.Always clear ice and heavy snowfrom the windshield before using thewindshield wipers.

If the overload is caused by anelectrical problem and not snow orice, be sure to get it fixed.

Fuses and CircuitBreakersThe wiring circuits in the vehicle areprotected from short circuits by acombination of fuses and circuitbreakers. This greatly reduces thechance of damage caused byelectrical problems.

To check a fuse, look at thesilver-colored band inside the fuse.If the band is broken or melted,replace the fuse. Be sure to replacea bad fuse with a new one of theidentical size and rating.

Fuses of the same amperage canbe temporarily borrowed fromanother fuse location, if a fuse goesout. Replace the fuse as soon aspossible.

To identify and check fuses, circuitbreakers, and relays, see EngineCompartment Fuse Block onpage 10-35 and Instrument PanelFuse Block on page 10-39.

All-Season TiresThis vehicle may come withall-season tires. These tires aredesigned to provide good overallperformance on most road surfacesand weather conditions. Originalequipment tires designed to GM'sspecific tire performance criteriahave a TPC specification codemolded onto the sidewall. Originalequipment all-season tires can beidentified by the last two charactersof this TPC code, which willbe “MS.”

Consider installing winter tires onthe vehicle if frequent driving onsnow or ice-covered roads isexpected. All-season tires provideadequate performance for mostwinter driving conditions, but theymay not offer the same level oftraction or performance as wintertires on snow or ice-covered roads.See Winter Tires on page 10-43.

Winter TiresThis vehicle was not originallyequipped with winter tires. Wintertires are designed for increasedtraction on snow and ice-coveredroads. Consider installing wintertires on the vehicle if frequentdriving on ice or snow coveredroads is expected. See your dealerfor details regarding winter tireavailability and proper tire selection.Also, see Buying New Tires onpage 10-57.

With winter tires, there may bedecreased dry road traction,increased road noise, and shortertread life. After changing to wintertires, be alert for changes in vehiclehandling and braking.

If using winter tires:. Use tires of the same brand and

tread type on all four wheelpositions.

. Use only radial ply tires of thesame size, load range, andspeed rating as the originalequipment tires.

Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.

Summer TiresThis vehicle may come with highperformance summer tires. Thesetires have a special tread andcompound that are optimized formaximum dry and wet roadperformance. This special tread andcompound will decreaseperformance in cold climates, andon ice and snow. We recommendinstalling winter tires on the vehicleif frequent driving in coldtemperatures or on snow or icecovered roads is expected. SeeWinter Tires on page 10-43.

The Tire and LoadingInformation label on the vehicleindicates the original equipmenttires and the correct cold tireinflation pressures. Therecommended pressure is theminimum air pressure needed tosupport the vehicle's maximumload carrying capacity. SeeVehicle Load Limits onpage 9-10.

How the vehicle is loadedaffects vehicle handling and ridecomfort. Never load the vehiclewith more weight than it wasdesigned to carry.

When to Check

Check the tires once a month ormore. Do not forget the compactspare, if the vehicle has one.The cold compact spare tirepressure should be at 420 kPa(60 psi). See Compact SpareTire on page 10-76.

How to Check

Use a good quality pocket-typegauge to check tire pressure.Proper tire inflation cannot bedetermined by looking at the tire.Check the tire inflation pressurewhen the tires are cold, meaningthe vehicle has not been drivenfor at least three hours or nomore than 1.6 km (1 mi).

Remove the valve cap from thetire valve stem. Press the tiregauge firmly onto the valve toget a pressure measurement.If the cold tire inflation pressurematches the recommendedpressure on the Tire andLoading Information label, nofurther adjustment is necessary.If the inflation pressure is low,add air until the recommendedpressure is reached. If theinflation pressure is high, presson the metal stem in the centerof the tire valve to release air.

Recheck the tire pressure withthe tire gauge.

Return the valve caps on thevalve stems to prevent leaksand keep out dirt and moisture.

Tire Pressure forHigh-Speed Operation

{ Warning

Driving at high speeds, 160 km/h(100mph) or higher, puts anadditional strain on tires.Sustained high-speed drivingcauses excessive heat buildupand can cause sudden tire failure.You could have a crash and youor others could be killed. Somehigh-speed rated tires requireinflation pressure adjustment forhigh-speed operation. Whenspeed limits and road conditionsare such that a vehicle can bedriven at high speeds, make sure

the tires are rated for high-speedoperation, in excellent condition,and set to the correct cold tireinflation pressure for thevehicle load.

Vehicles with P245/45R19 size tiresrequire inflation pressure adjustmentwhen driving the vehicle at speedsof 160 km/h (100 mph) or higher.Set the cold inflation pressure to248 kPa (36 psi).

Vehicles with P245/40R20 size tiresrequire inflation pressure adjustmentwhen driving the vehicle at speedsof 160 km/h (100 mph) or higher.Set the cold inflation pressure to270 kPa (39 psi).

Return the tires to therecommended cold tire inflationpressure when high-speed drivinghas ended. See Vehicle Load Limitson page 9-10 and Tire Pressure onpage 10-49.

Tire Pressure MonitorSystemThe Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings to areceiver located in the vehicle.

Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)

As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a low tire

pressure telltale when one or moreof your tires is significantlyunder-inflated.

Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving on asignificantly under-inflated tirecauses the tire to overheat and canlead to tire failure. Under-inflationalso reduces fuel efficiency and tiretread life, and may affect thevehicle's handling and stoppingability.

Please note that the TPMS is not asubstitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under-inflation hasnot reached the level to triggerillumination of the TPMS low tirepressure telltale.

Your vehicle has also beenequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.

The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start-ups aslong as the malfunction exists.

When the malfunction indicator isilluminated, the system may not beable to detect or signal low tirepressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.

See Tire Pressure MonitorOperation on page 10-52.

See Radio Frequency Statement onpage 13-15.

Tire Pressure MonitorOperationThis vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressure inthe tires and transmits the tirepressure readings to a receiverlocated in the vehicle.

When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning light

located on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. See Vehicle LoadLimits on page 9-10.

A message to check the pressure ina specific tire displays in the DriverInformation Center (DIC). The lowtire pressure warning light and theDIC warning message come on ateach ignition cycle until the tires areinflated to the correct inflationpressure. Using the DIC, tirepressure levels can be viewed. Foradditional information and detailsabout the DIC operation anddisplays see Driver InformationCenter (DIC) on page 5-27.

The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thiscould be an early indicator that theair pressure is getting low andneeds to be inflated to the properpressure.

TPMS Malfunction Light andMessage

The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. When thesystem detects a malfunction, thelow tire warning light flashes forabout one minute and then stays onfor the remainder of the ignitioncycle. A DIC warning message alsodisplays. The malfunction light andDIC warning message come on ateach ignition cycle until the problemis corrected. Some of the conditionsthat can cause these to comeon are:. One of the road tires has been

replaced with the spare tire. Thespare tire does not have a

TPMS sensor. The malfunctionlight and DIC message shouldgo off after the road tire isreplaced and the sensormatching process is performedsuccessfully. See “TPMS SensorMatching Process” later in thissection.

. The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process. See"TPMS Sensor MatchingProcess" later in this section.

. One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed andthe sensor matching process isperformed successfully. Seeyour dealer for service.

. Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly. See BuyingNew Tires on page 10-57.

. Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.

If the TPMS is not functioningproperly it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message comes onand stays on.

TPMS Sensor MatchingProcess

Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’s tires or replacing one ormore of the TPMS sensors. TheTPMS sensor matching process

should also be performed afterreplacing a spare tire with a roadtire containing the TPMS sensor.The malfunction light and the DICmessage should go off at the nextignition cycle. The sensors arematched to the tire/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.See your dealer for service or topurchase a relearn tool.

There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.

The TPMS sensor matchingprocess is:

1. Set the parking brake.

2. Turn the ignition to ON/RUN withthe engine off or place thevehicle power mode in ON/RUN/

START. See Ignition Positions(Key Access) on page 9-15 orIgnition Positions (KeylessAccess) on page 9-16.

3. Make sure the Tire Pressure infopage option is turned on. Theinfo pages on the DIC can beturned on and off through theSettings menu. See DriverInformation Center (DIC) onpage 5-27.

4. Use the DIC controls on the rightside of the steering wheel toscroll to the Tire Pressurescreen under the DIC info page.

5. Press and hold the V (Set/Reset) button located in thecenter of the DIC controls.

The horn sounds twice to signalthe receiver is in relearn modeand the TIRE LEARNINGACTIVE message displays onthe DIC screen.

6. Start with the driver sidefront tire.

Tire InspectionWe recommend that the tires,including the spare tire, if thevehicle has one, be inspectedfor signs of wear or damage atleast once a month.

Replace the tire if:. The indicators at three or

more places around the tirecan be seen.

. There is cord or fabricshowing through the tire'srubber.

. The tread or sidewall iscracked, cut, or snaggeddeep enough to show cord orfabric.

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

. The tire has a puncture, cut,or other damage that cannotbe repaired well because ofthe size or location of thedamage.

Tire RotationTires should be rotated every12 000 km (7,500 mi). SeeMaintenance Schedule onpage 11-2.

Tires are rotated to achieve auniform wear for all tires. Thefirst rotation is the mostimportant.

Anytime unusual wear isnoticed, rotate the tires as soonas possible, check for proper tire

When It Is Time for NewTiresFactors such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.

Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining. See TireInspection on page 10-55 and TireRotation on page 10-55.

The rubber in tires ages over time.This also applies to the spare tire,if the vehicle has one, even if it isnever used. Multiple factorsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place. GM recommends thattires, including the spare ifequipped, be replaced after sixyears, regardless of tread wear. Thetire manufacture date is the last fourdigits of the DOT Tire IdentificationNumber (TIN) which is molded intoone side of the tire sidewall. Thefirst two digits represent the week(01–52) and the last two digits, theyear. For example, the third week ofthe year 2010 would have afour-digit DOT date of 0310.

Vehicle Storage

Tires age when stored normallymounted on a parked vehicle. Parka vehicle that will be stored for atleast a month in a cool, dry, cleanarea away from direct sunlight toslow aging. This area should be free

of grease, gasoline, or othersubstances that can deterioraterubber.

Parking for an extended period cancause flat spots on the tires thatmay result in vibrations whiledriving. When storing a vehicle forat least a month, remove the tires orraise the vehicle to reduce theweight from the tires.

Buying New TiresGM has developed and matchedspecific tires for the vehicle. Theoriginal equipment tires installedwere designed to meet GeneralMotors Tire Performance CriteriaSpecification (TPC Spec)system rating. Whenreplacement tires are needed,GM strongly recommendsbuying tires with the same TPCSpec rating.

GM's exclusive TPC Specsystem considers over a dozencritical specifications that impact

the overall performance of thevehicle, including brake systemperformance, ride and handling,traction control, and tirepressure monitoringperformance. GM's TPC Specnumber is molded onto the tire'ssidewall near the tire size. If thetires have an all-season treaddesign, the TPC Spec numberwill be followed by MS for mudand snow. See Tire SidewallLabeling on page 10-44.

GM recommends replacing worntires in complete sets of four.Uniform tread depth on all tireswill help to maintain theperformance of the vehicle.Braking and handlingperformance may be adverselyaffected if all the tires are notreplaced at the same time.If proper rotation andmaintenance have been done,all four tires should wear out atabout the same time. See Tire

Rotation on page 10-55.However, if it is necessary toreplace only one axle set ofworn tires, place the new tireson the rear axle.

Winter tires with the same speedrating as the original equipmenttires may not be available for H,V, W, Y and ZR speed ratedtires. Never exceed the wintertires’ maximum speed capabilitywhen using winter tires with alower speed rating.

{ Warning

Tires could explode duringimproper service. Attemptingto mount or dismount a tirecould cause injury or death.Only your dealer or authorizedtire service center shouldmount or dismount the tires.

{ Warning

Mixing tires of different sizes,brands, or types may causeloss of control of the vehicle,resulting in a crash or othervehicle damage. Use thecorrect size, brand, and typeof tires on all wheels.

{ Warning

Using bias-ply tires on thevehicle may cause the wheelrim flanges to develop cracksafter many miles of driving.A tire and/or wheel could failsuddenly and cause a crash.Use only radial-ply tires withthe wheels on the vehicle.

Vehicles that have a tirepressure monitoring systemcould give an inaccuratelow-pressure warning if non-TPCSpec rated tires are installed.See Tire Pressure MonitorSystem on page 10-51.

The Tire and LoadingInformation label indicates theoriginal equipment tires on thevehicle. See Vehicle Load Limitson page 9-10.

Different Size Tires andWheelsIf wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollover

may be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, tractioncontrol, electronic stability control,or All-Wheel Drive, the performanceof these systems can also beaffected.

{ Warning

If different sized wheels are used,there may not be an acceptablelevel of performance and safety iftires not recommended for thosewheels are selected. Thisincreases the chance of a crashand serious injury. Only use GMspecific wheel and tire systemsdeveloped for the vehicle, andhave them properly installed by aGM certified technician.

nominal rim diameters of10 to 12 inches (25 to 30 cm),or to some limited-productiontires.

While the tires available onGeneral Motors passenger carsand light trucks may vary withrespect to these grades, theymust also conform to federalsafety requirements andadditional General Motors TirePerformance Criteria (TPC)standards.

All Passenger Car Tires MustConform to Federal SafetyRequirements In Addition ToThese Grades.

Treadwear

The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government testcourse. For example, a tire

graded 150 would wear one andone-half (1½) times as well onthe government course as a tiregraded 100. The relativeperformance of tires dependsupon the actual conditions oftheir use, however, and maydepart significantly from thenorm due to variations in drivinghabits, service practices anddifferences in roadcharacteristics and climate.

Traction

The traction grades, fromhighest to lowest, are AA, A, B,and C. Those grades representthe tire's ability to stop on wetpavement as measured undercontrolled conditions onspecified government testsurfaces of asphalt andconcrete. A tire marked C mayhave poor traction performance.Warning: The traction gradeassigned to this tire is based on

straight-ahead braking tractiontests, and does not includeacceleration, cornering,hydroplaning, or peak tractioncharacteristics.

Temperature

The temperature grades are A(the highest), B, and C,representing the tire's resistanceto the generation of heat and itsability to dissipate heat whentested under controlledconditions on a specified indoorlaboratory test wheel. Sustainedhigh temperature can cause thematerial of the tire to degenerateand reduce tire life, andexcessive temperature can leadto sudden tire failure. The gradeC corresponds to a level ofperformance which allpassenger car tires must meetunder the Federal Motor SafetyStandard No. 109. Grades B andA represent higher levels of

Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.

Wheel Alignment and TireBalanceThe tires and wheels were alignedand balanced at the factory toprovide the longest tire life and bestoverall performance. Adjustments towheel alignment and tire balancingare not necessary on a regularbasis. Consider an alignment checkif there is unusual tire wear or thevehicle is significantly pulling to oneside or the other. Some slight pull tothe left or right, depending on thecrown of the road and/or other road

surface variations such as troughsor ruts, is normal. If the vehicle isvibrating when driving on a smoothroad, the tires and wheels may needto be rebalanced. See your dealerfor proper diagnosis.

Wheel ReplacementReplace any wheel that is bent,cracked, or badly rusted orcorroded. If wheel nuts keep comingloose, the wheel, wheel bolts, andwheel nuts should be replaced.If the wheel leaks air, replace it.Some aluminum wheels can berepaired. See your dealer if any ofthese conditions exist.

Your dealer will know the kind ofwheel that is needed.

Each new wheel should have thesame load-carrying capacity,diameter, width, offset, and bemounted the same way as the one itreplaces.

Replace wheels, wheel bolts, wheelnuts, or Tire Pressure MonitorSystem (TPMS) sensors with newGM original equipment parts.

{ Warning

Using the wrong replacementwheels, wheel bolts, or wheelnuts can be dangerous. It couldaffect the braking and handling ofthe vehicle. Tires can lose air,and cause loss of control, causinga crash. Always use the correctwheel, wheel bolts, and wheelnuts for replacement.

{ Warning

Replacing a wheel with a usedone is dangerous. How it hasbeen used or how far it has beendriven may be unknown. It couldfail suddenly and cause a crash.When replacing wheels, use anew GM original equipmentwheel.

Tire Chains

{ Warning

Do not use tire chains. There isnot enough clearance. Tire chainsused on a vehicle without theproper amount of clearance cancause damage to the brakes,suspension, or other vehicleparts. The area damaged by thetire chains could cause loss ofcontrol and a crash.

Use another type of tractiondevice only if its manufacturerrecommends it for the vehicle'stire size combination and roadconditions. Follow thatmanufacturer's instructions. Toavoid vehicle damage, drive slowand readjust or remove thetraction device if it contacts thevehicle. Do not spin the wheels.If traction devices are used, installthem on the front tires.

If a Tire Goes FlatIt is unusual for a tire to blow outwhile driving, especially if the tiresare maintained properly. See Tireson page 10-42. If air goes out of atire, it is much more likely to leakout slowly. But if there is ever ablowout, here are a few tips aboutwhat to expect and what to do:

If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your foot offthe accelerator pedal and grip thesteering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.

A rear blowout, particularly on acurve, acts much like a skid andmay require the same correction asused in a skid. Stop pressing theaccelerator pedal and steer tostraighten the vehicle. It may bevery bumpy and noisy. Gently braketo a stop, well off the road,if possible.

Collision Damage RepairIf the vehicle is involved in acollision and it is damaged, have thedamage repaired by a qualifiedtechnician using the properequipment and quality replacementparts. Poorly performed collisionrepairs diminish the vehicle resale

value, and safety performance canbe compromised in subsequentcollisions.

Collision Parts

Genuine GM Collision parts are newparts made with the same materialsand construction methods as theparts with which the vehicle wasoriginally built. Genuine GMCollision parts are the best choice toensure that the vehicle's designedappearance, durability, and safetyare preserved. The use of GenuineGM parts can help maintain the GMNew Vehicle Limited Warranty.

Recycled original equipment partsmay also be used for repair. Theseparts are typically removed fromvehicles that were total losses inprior crashes. In most cases, theparts being recycled are fromundamaged sections of the vehicle.A recycled original equipment GMpart may be an acceptable choice tomaintain the vehicle's originallydesigned appearance and safetyperformance; however, the history of

these parts is not known. Such partsare not covered by the GM NewVehicle Limited Warranty, and anyrelated failures are not covered bythat warranty.

Aftermarket collision parts are alsoavailable. These are made bycompanies other than GM and maynot have been tested for the vehicle.As a result, these parts may fitpoorly, exhibit premature durability/corrosion problems, and may notperform properly in subsequentcollisions. Aftermarket parts are notcovered by the GM New VehicleLimited Warranty, and any vehiclefailure related to such parts is notcovered by that warranty.

Repair Facility

GM also recommends that youchoose a collision repair facility thatmeets your needs before you everneed collision repairs. Your dealermay have a collision repair centerwith GM-trained technicians andstate‐of‐the‐art equipment, or beable to recommend a collision repair

Insuring the Vehicle

Protect your investment in the GMvehicle with comprehensive andcollision insurance coverage. Thereare significant differences in thequality of coverage afforded byvarious insurance policy terms.Many insurance policies providereduced protection to the GMvehicle by limiting compensation fordamage repairs through the use ofaftermarket collision parts. Someinsurance companies will notspecify aftermarket collision parts.When purchasing insurance, werecommend that you ensure that thevehicle will be repaired with GMoriginal equipment collision parts.If such insurance coverage is notavailable from your currentinsurance carrier, consider switchingto another insurance carrier.

If the vehicle is leased, the leasingcompany may require you to haveinsurance that ensures repairs withGenuine GM Original EquipmentManufacturer (OEM) parts orGenuine Manufacturer replacementparts. Read the lease carefully, asyou may be charged at the end ofthe lease for poor quality repairs.

If a Crash Occurs

If there has been an injury, callemergency services for help. Do notleave the scene of a crash until allmatters have been taken care of.Move the vehicle only if its positionputs you in danger, or you areinstructed to move it by a policeofficer.

Give only the necessary informationto police and other parties involvedin the crash.

Managing the Vehicle DamageRepair Process

In the event that the vehicle requiresdamage repairs, GM recommendsthat you take an active role in itsrepair. If you have a pre-determinedrepair facility of choice, take thevehicle there, or have it towed there.Specify to the facility that anyrequired replacement collision partsbe original equipment parts, eithernew Genuine GM parts or recycledoriginal GM parts. Remember,recycled parts will not be covered bythe GM vehicle warranty.

Insurance pays the bill for the repair,but you must live with the repair.Depending on your policy limits,your insurance company mayinitially value the repair usingaftermarket parts. Discuss this withthe repair professional, and insist onGenuine GM parts. Remember,if the vehicle is leased, you may beobligated to have the vehiclerepaired with Genuine GM parts,even if your insurance coveragedoes not pay the full cost.

If another party's insurancecompany is paying for the repairs,you are not obligated to accept arepair valuation based on thatinsurance company's collision policyrepair limits, as you have nocontractual limits with that company.In such cases, you can have controlof the repair and parts choices aslong as the cost stays withinreasonable limits.

Event Data RecordersThis vehicle is equipped with anevent data recorder (EDR). Themain purpose of an EDR is torecord, in certain crash or nearcrash-like situations, such as an airbag deployment or hitting a roadobstacle, data that will assist inunderstanding how a vehicle’ssystems performed. The EDR isdesigned to record data related tovehicle dynamics and safetysystems for a short period of time,typically 30 seconds or less. TheEDR in this vehicle is designed torecord such data as:. How various systems in your

vehicle were operating;. Whether or not the driver and

passenger safety belts werebuckled/fastened;

. How far (if at all) the driver wasdepressing the accelerator and/or brake pedal; and,

. How fast the vehicle wastraveling.

These data can help provide abetter understanding of thecircumstances in which crashes andinjuries occur. NOTE: EDR data arerecorded by your vehicle only if anon-trivial crash situation occurs; nodata are recorded by the EDR undernormal driving conditions and nopersonal data (e.g., name, gender,age, and crash location) arerecorded. However, other parties,such as law enforcement, couldcombine the EDR data with the typeof personally identifying dataroutinely acquired during a crashinvestigation.

To read data recorded by an EDR,special equipment is required, andaccess to the vehicle or the EDR isneeded. In addition to the vehiclemanufacturer, other parties, such aslaw enforcement, that have thespecial equipment, can read theinformation if they have access tothe vehicle or the EDR.

GM will not access this data orshare it with others except: with theconsent of the vehicle owner or,

if the vehicle is leased, with theconsent of the lessee; in responseto an official request by police orsimilar government office; as part ofGM's defense of litigation throughthe discovery process; or, asrequired by law. Data that GMcollects or receives may also beused for GM research needs or maybe made available to others forresearch purposes, where a need isshown and the data is not tied to aspecific vehicle or vehicle owner.
