QuestionsandAnswersAbout SafetyBelts

Q: Willlbetrappedinthevehicle afteracrashiflamwearinga safetybelt?

A: You could be—whether you are wearing as safety belt or not. But your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. And you can unbuckle as safety belt, even if you are upsidedown.

Q: If my vehicle has air bags, why should have to wear safety belts?

A: Airbagsaresupplemental systemsonly; sotheyworkwith safetybelts—notinsteadof them. Whetherornotanairbag isprovided, allooccupantsstill havetobuckleuptogetthe mostprotection. Thatistrue notonlyinfrontalcollisions, butespeciallyinsideand othercollisions.

Q: Iflamagooddriver, and I neverdrive far from home, why shouldl wears safety belts?

A: You may bean excellent driver, but if you are in acrash—even on that is not your fault—you and your passenger(s) can be hurt. Being a good driver does not protect you from things beyond your control, such as baddrivers.

WhenShouldanAirbag Inflate?

Frontalairbagsaredesignedto inflateinmoderatetoseverefrontal ornear-frontalcrashestohelp reducethepotentialforsevere injuriesmainlytothedriver'sor rightfrontpassenger'sheadand chest.However,theyareonly designedtoinflateiftheimpact exceedsapredetermined deploymentthreshold.Deployment thresholdsareusedtopredicthow severeacrashislikelytobeintime fortheairbagstoinflateandhelp restraintheoccupants.

Whether the frontal air bags will or should deploy is not based on how fast your vehicle is traveling. It depends largely on what you hit, the direction of the impact, and how quickly your vehicles slows down.

Frontalairbagsmayinflate atdifferentcrashspeeds. Forexample:

  • Ifthevehiclehitsastationary object, theairbagscouldinflate atadifferentcrashspeedthanif thevehiclehitsamovingobject.
  • Ifthevehiclehitsanobjectthat deforms,theairbagscould inflateatadifferentcrashspeed thanifthevehiclehitsanobject thatdoesnotdeform.
  • Ifthevehiclehitsanarrowobject (likeapole), theairbags could inflate at different crash speed than if the vehicle hits a wide object (likeawall).
  • Ifthevehiclegoesintoanobject atanangle, theairbags could inflate at different crash speed than if the vehiclegoes straight into the object.

Thresholdscanalsovarywith specificvehicledesign.

Frontalairbagsarenotintendedto inflateduringvehiclerollovers, rear impacts, orinmanysideimpacts.

Inaddition, the vehicle has dual-stage frontal airbags. Dual-stage airbags adjust the restraint according to crash severity. The vehicle has electronic frontal sensors, which help the sensing system distinguish between a moderate frontal impact and more severe frontal impact. Form moderate frontal impacts, dual-stage airbags inflate at level less than full deployment. Form more severe frontal impacts, full deployment occurs.

The vehicle has seat-mounted side impact and roof-rail air bags. See Airbag System on page 2-25. Seat-mounted side impact and roof-rail air bags are intended to inflate in moderate to severe crashes. In addition, the seroof-rail air bags are intended to inflate during a rollover or inasevere frontal impact. Seat-mounted side impact and roof-rail air bags will inflate if the crash severity is above

thesystem'sdesignedthreshold level. Thethresholdlevelcanvary withspecificvehicledesign.

Roof-railairbagsarenotintendedto inflateinrearimpacts. Bothroof-rail airbagswilldeploywheneitherside ofthevehicleisstruckorifthe sensingsystempredictsthatthe vehicleisabouttorollover, orin aseverefrontalimpact.

Inanyparticularcrash, noonecan saywhetheranairbagshouldhave inflatedsimplybecauseofthe damagetoavehicleorbecause ofwhattherepaircostswere. Forfrontalairbags, inflationis determinedbywhatthevehiclehits, theangleoftheimpact,andhow quicklythevehicleslowsdown. Forseat-mountedsideimpactand roof-railairbags, deploymentis determinedbythelocationand severityofthesideimpact.

Inarolloverevent, roof-railairbag deployment is determined by the direction of the roll.

Frontalairbagmodulesarelocated insidethesteeringwheel and instrumentpanel. For vehicles with seat-mounted side impact airbags, there are airbag modules in the side of the front seat back close to the door. For vehicles with roof-rail airbags, there are airbag modules in the ceiling of the vehicle, near the sidewindow sthathave occupant seating positions.

Q: Isthereanythinglmightadd toorchangeaboutthevehicle thatcouldkeeptheairbags fromworkingproperly?

A: Yes. If you add things that changethe vehicle's frame, bumpersystem, height, frontend or sidesheet metal, they may keep the air bags system from working properly. Changing or moving any part of the front seats, safety belts, the airbag sensing and diagnostic module, steering wheel, instrument panel, roof-rail air bag modules, ceiling headliner or pillargarnish trim, frontsensors, side impact sensors, or air bag wiring can affect the operation of the air bag system.

Inaddition, the vehicle has a passengersensingsystem fortherightfrontpassenger

position, which includessensors that are part of the passenger seat. The passengers sensing system may not operate properly if the original seat trim is replaced with non-GM covers, upholstery ortrim, or with GM covers, upholstery ortrim designed for different vehicle. Any object, such as an aftermarket seat theater or a comfort-enhancing pador device, installed under or on top of these at fabric, could also interfere with the operation of the passengers sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent the passengers sensing system from properly turning off the passenger airbag(s).

BatteryLoad Management

The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjust the voltage for best performance and extended life of the battery.

Whenthebattery'sstateofcharge islow,thevoltageisraisedslightly toquicklybringthechargebackup. Whenthestateofchargeishigh, thevoltageisloweredslightlyto preventovercharging.Ifthevehicle hasavoltmetergaugeoravoltage displayontheDriverInformation Center(DIC),youmayseethe voltagemoveupordown.This is normal.Ifthereisaproblem,an alertwillbedisplayed.

The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This because the generator (alternator) may not be spinning fast enough that lidetoproduce all the power that is needed for very high electrical loads.

Ahighelectricloadoccurswhen severalofthefollowingareon,such as:headlamps,highbeams,fog lamps,rearwindowdefogger, climatecontrolfanathighspeed, heatedseats,enginecoolingfans, trailerloads,andloadspluggedinto accessorypoweroutlets.

Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest level of corrective action, this action may be notice able to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVERACTIVE, BATTERY VOLTAGELOW, or LOWBATTERY.

ControlofaVehicle

The following three systems helpto control the vehicle while driving—brakes, steering, and accelerator. Attimes, as when driving on snow orice, it is easy to ask more of those control systems than the tires and road can provide. Meaning, you can lose control of the vehicle. See Traction Control System (TCS) on page 8-34.

Addingnon-dealer/non-retailer accessoriescanaffective vehicle performance. See Accessories and Modifications on page 9-3.

Braking

SeeBrakeSystemWarningLight onpage4-19.

Brakingactioninvolvesperception timeandreactiontime.Decidingto pushthebrakepedalisperception time.Actuallydoingitis reactiontime.

Averagereactiontimeisabout three-fourthsofasecond. But that is only an average. It might be less with one driver and as long as two or three seconds more with another. Age, physical condition, alertness, coordination, and eyesight all play apart. Sodo alcohol, drugs, and frustration. But even in three-fourth sofasecond, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft). That could be a lot of distance in an emergency, so keeping enough space between the vehicle and others is important.

And, of course, actual stopping distances vary greatly with the surface of the road, whether it is pavement or gravel; the condition of the road, whether it is wet, dry, or icy; tiretread; the condition of the brakes; the weight of the vehicle; and the amount of brake force applied.

Avoidneedlessheavy braking.Somepeopledrivein spurts—heavyacceleration followedbyheavybraking—rather thankeepingpacewithtraffic.This isamistake.Thebrakesmightnot havetimetocoolbetweenhard stops.Thebrakeswillwearout muchfasterwithalotofheavy braking.Keepingpacewiththe trafficandallowingrealisticfollowing distanceseliminatesalotof unnecessarybraking.Thatmeans betterbrakingandlongerbrakelife.

Drivewith caution, whatever the condition. Accelerategently so traction is not lost. Accelerating too quickly cause the wheel stospin and make the surface under the tiresslick, so there is even less traction.

Trynottobreakthefragiletraction. If you accelerate at toofast, the drive wheels will spin and polish the surface under the tire seven more.

BrakeAssist

This vehicle has a brake assist feature designed to assist the driver instopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brakesystem under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stoporslowdown the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsations or pedalmovement during this time is normal and the drivers should continueto apply the brake pedal asthedriving situation dictates. The brake assist feature will automatically disengag when the brake pedal is released or brake pedal pressure is quickly decreased.

RideControlSystems

TractionControl System(TCS)

The vehicle has attraction control system that limits wheel spin. This is especially useful in slippery road conditions. On a front-wheel-drive vehicle, the system operates if its sense that one or both of the front wheels are spinning or beginning to lose traction. On all-Wheel-Drive (AWD) vehicle, the system will operate if its sense that any of the wheels are spinning or beginning to lose traction. Whent his happens, the system brakes the spinning wheel(s) and/or reduces engine power limit wheel spin.

Fortrailer ing capacity, see Trailer Towing (2.4LL4Engine) on page 8-58 or Trailer Towing (3.0Land3.6L V6 Engines) on page 8-58. Trailering changeshandling, acceleration, braking, durability and fueleconomy. With the added weight, the engine, transmission, wheel assemblies and tires are forced to work harder and under greater loads. The trailer also adds wind resistance, increasing the pulling requirements. Forsafe trailering, correctly set the proper trailing equipment.

The following information has important trailering tips and rules for yoursafety and that of your passengers. Read this section carefully before pulling at a trailer.

PullingATrailer

Herearesomeimportantpoints:

  • Therearemanylaws, including speedlimitrestrictionsthatapply totrailering. Checkforlegal requirementswithstateor provincialpolice.
  • Donottowatraileratallduring thefirst1600km(1,000miles) thenewvehicleisdriven. The engine,axleorotherpartscould bedamaged.

Duringthetrip, checkregularlytobe surethattheloadissecure, and the lampsandtrailerbrakesareworking properly.

TowingwithaStabilityControl System

Whentowing, the sound of the stability control system might be heard. Thesystem is reacting to the vehicle movement caused by the trailer, which mainly occurs during cornering. This is normal when towing heavier trailers.

FollowingDistance

Stayatleasttwiceasfarbehindthe vehicleaheadasyouwouldwhen drivingthevehiclewithoutatrailer. Thiscanhelptoavoidsituations thatrequireheavybrakingand suddenturns.

If the vehicle is damaged in an accident, the aim of the headlamps may be affected and adjustment may be necessary.

It is recommended that a dealer/retailer adjust the headlamps. Tore-aim the headlamps yourself, us the following procedure.

The vehicles should be properly prepared as follows:

  • The vehicles should be placed so the headlamps are 7.6m (25ft.) from alight colored wall.
    • The vehicle must have all four tireson levelsurface which is level all the way to the wall.

9-32VehicleCare

• The vehicles should be placed so it is perpendicular to the wall or other flatsurface.
• The vehicles should not have any snow, ice, ormudonit.
- The vehicles should be fully assembled and all other work stopped while headlampaiming is being performed.
• The vehicles should be normally loaded with a full tank off fuel and one person or 75 kg (160 lbs) sitting in the driver's seat.
• Tiresshouldbeproperlyinflated.

Headlampaiming is done with the vehicle's slow-beam headlamps. The high-beam headlamp will be correctly aimed if the low-beam headlamps are aimed properly.

TirePressure

Tiresneedthecorrectamount of airpressuretooperate effectively.

Notice: Donotletanyonetell youthatunder-inflationor over-inflationisallright. It is not. If your tires donothave enough hair (under-inflation), you can get the following:

  • Toomuchflexing
  • Toomuchheat
  • Tireoverloading
    • Prematureor irregularwear
  • Poorhandling
  • Reducedfueleconomy

If your tireshavetoomuchair (over-inflation), you can get the following:

  • Unusualwear
  • Poorhandling
  • Roughride
  • Needlessdamagefrom roadhazards

Avehiclespecific Tire and Loading Information label is attached to your vehicle. This label shows your vehicle's originalequipment tires and the correct inflation pressures for your tires when they are cold. There recommended cold tire inflation pressure, shown on the label, istheminimum amount of air pressure needed to support your vehicle's maximum load carrying capacity.

For additional information regarding how much weight your vehicle can carry, and an example of the Tire and Loading Information label, see Vehicle Load Limits on page 8-12. How you load your vehicle affects vehicle handling and ride comfort. Never load your vehicle with more weight than it was designed to carry.

WhentoCheck

Check your tires once a month ormore. Donot forget to check the compact spare tire, if the vehicle has one. The compact spa should be 60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire on page9-76.

HowtoCheck

Useagoodqualitypocket-type gaugetochecktirepressure. Youcannottellifyourtiresare properlyinflatedsimplyby lookingatthem.Radialtiresmay lookproperlyinflatedevenwhen theyareunder-inflated.Check thetire'sinflationpressurewhen thetiresarecold.Coldmeans yourvehiclehasbeensittingfor atleastthreehoursordrivenno morethan1.6km(1mile).

Removethevalvecapfromthe tirevalvestem.Pressthetire gaugefirmlyontothevalveto getapressuremeasurement.

If the cold tire inflation pressure match there recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is slow, add air until you reach the recommended amount.

If you overfill the tire, release air bypassing on themetal stem in the center of the tire valve. Re-check the tire pressure with the tire gauge.

Besuretoputthevalvecaps backonthevalvestems. They helppreventleaksbykeeping outdirtandmoisture.

TirePressureMonitor System

The TirePressureMonitorSystem (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your vehicle's tires and transmittire pressure reading to are receiver located in the vehicle.

Eachtire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressurerecommended by the vehicle manufacturer on the vehicle placardortire inflation pressure label. (If your vehicle has tires of different sizing thanthesize indicated on the vehicle placardor tire inflation pressure label, you should determinethe propertire inflation pressure forthosetires.)

9-58VehicleCare

Asanadded safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pressure telltale when none or more of your tires significantly under-inflated.

Accordingly, whentelowtire pressuretelltaleilluminates, you shouldstopandcheckyourtiresas soonaspossible, andinflatethem totheproperpressure.

TirePressureMonitor Operation

This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when alow tire pressure condition exists. TPMS sensors are mounted on to each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the vehicle's tires and transmits the tire pressurereading to are receiver located in the vehicle.

Buick Lacrosse (2010) - TirePressureMonitor Operation - 1

When alow tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument panel cluster. If the warning light comes on, stop as soon as possible and

TPMSMalfunctionLightand Message

The TPMS will not function properly if one or more of the TPMS sensors are missing or in operable. When the system detects a malfunction, the low tire warning light flashes for about on minute and then stay on forward remainder of the ignition cycle. ADIC warning message is also displayed. The low tire warning light and DIC warning message come on at each ignition cycle until the problem is corrected. Some of the condition that can cause the malfunction light and DIC message to come on are:

GM's exclusive TPCSpec system considers over a dozen critical specifications that impact the overall performance of your vehicle, including brakesystem performance, ride and handling, traction control, and tire pressure monitoring performance. GM's TPCSpec number is molded onto the tire's sidewall near the tiresize. If the tires have an all-season tread design, the TPCSpec number will be followed by an MS for mud and snow. See Tire Sidewall Labeling on page 9-49 for additional information.

Treadwear200TractionAA TemperatureA

The following information relates to the system developed by the United States National Highway Traffic Safety Administration (NHTSA), which gradestires by treadwear, traction, and temperature performance. This applies only to vehicles sold in the United States. The grades are molded on the sidewall of most passenger car tires. The Uniform Tire Quality

Grading(UTQG)systemdoes notapplytodeeptread, winter-typesnowtires, space-saver,ortemporaryuse sparetires,tireswithnominal rimdiametersof10to12inches (25to30cm),ortosome limited-productiontires.

While the tires available on General Motors passengers cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.

All Passenger Car Tires Must Conform to Federal Safety Requirements In Addition To These Grades.

Treadwear

Thetreadweargradeisa comparativeratingbasedonthe wearrateofthetirewhentested undercontrolledconditionson aspecifiedgovernmenttest course. Forexample, atire graded150wouldwearoneand ahalf(1½)timesaswellonthe governmentcourseasatire graded100. Therelative performanceoftiresdepends upontheactualconditionsof theiruse, however, and may departsignificantlyfromthe normduetovariationsin drivinghabits, servicepractices anddifferencesinroad characteristicsandclimate.

Traction-AA,A,B,C

Thetractiongrades, from highesttolowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled condition on specified government test surfaces of asphalt and concrete. At remarked C may have poor traction performance. Warning: Thetraction grade assigned to histire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

Temperature-A,B,C

ThetemperaturegradesareA (thehighest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled condition as specified indoor laboratory test wheel. Sustained hightemperature can cause thematerial of the tire to degenerate and reduce tire life, and excessively temperature can lead to sudden tire failure. The grade Corresponded level of performance which all passengercartires must meet under the Federal Motor Safety Standard No. 109. Grades Band Are present higher level sof performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for the tire is established for atirethatis

If you need to replace any of the wheels, wheel bolts, wheel nuts, or Tire Pressure Monitor System (TPMS) sensors, replacethemonly with new GM originalequipment parts. This way, you will be sure to have better right wheel, wheel bolts, wheel nuts, and TPMS sensors for the vehicle.

WARNING

Using the wrong replacement wheels, wheel bolts, or wheel nutson your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement.

Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer orodometeralibration, headlampaim, bumper height, vehicleground clearance, and tire ortirechain clearance to the body and chassis.

InsuringYourVehicle

Protect your investment in your GM vehicle with comprehensive and collision insurance coverage. There are significant differences in the quality of coverage afforded by various insurance policy terms.

Manyinsurancepoliciesprovide reducedprotectiontoyourGM vehiclebylimitingcompensation fordamagerepairsbyusing aftermarketcollisionparts.

Ifsuchinsurancecoverageis notavailablefromyourcurrent insurancecarrier,considerswitching toanotherinsurancecarrier.

If your vehicle is leased, the leasing company may require you to have insurance that assures repairs with Genuine GM Original Equipment Manufacturer (OEM) parts or Genuine Manufacturer replacement parts. Ready your lease carefully, as you maybe charged at the end of your lease for poor quality repairs.
