This feature uses thestability system hydraulic brakecontrol 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.The stability 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.The brake assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.Hill Start Assist (HSA)This vehicle has a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After the drivercompletely stops and holds thevehicle in a complete standstill on agrade, HSA will be automaticallyactivated. During the transitionperiod between when the driverreleases the brake pedal and startsto accelerate to drive off on a grade,HSA holds the braking pressure toensure that there is no rolling. Thebrakes will automatically releasewhen the accelerator pedal isapplied within the two‐secondwindow. It will not activate if thevehicle is in a drive gear and facingdownhill or if the vehicle is facinguphill and in R (Reverse).Ride Control SystemsTraction ControlSystem (TCS)The vehicle has a Traction ControlSystem (TCS) that limits wheel slip.The system operates if it sensesthat one or both of the front wheelsare slipping or beginning to losetraction. When this happens, thesystem reduces engine power and/or applies brake pressure to theslipping wheel(s).The system may be heard or feltwhile it is working, but this isnormal.TCS automatically comes onwhenever the vehicle is started.To limit wheel slip, especially inslippery road conditions, the systemshould always be left on.

To helpkeep the engine clean and maintainoptimum vehicle performance, werecommend the use of gasolineadvertised as TOP TIER DetergentGasoline.Look for the TOP TIER label on thefuel pump to ensure gasoline meetsenhanced detergency standardsdeveloped by auto companies. A listof marketers providing TOP TIERDetergent Gasoline can be found atwww.toptiergas.com.The eighth digit of the VehicleIdentification Number (VIN) showsthe code letter or number thatidentifies the vehicle's engine.The VIN is at the top left of theinstrument panel. See VehicleIdentification Number (VIN) onpage 12‑1.Recommended FuelIf the vehicle has a 2.4L L4 engine(VIN Code C), use regular unleadedgasoline with a posted octane ratingof 87 or higher. If the octane ratingis less than 87, an audible knockingnoise, commonly referred to asspark knock, might be heard whendriving. If this occurs, use agasoline rated at 87 octane orhigher as soon as possible. If heavyknocking is heard when usinggasoline rated at 87 octane orhigher, the engine needs service.If the vehicle has the 3.6L V6 engine(VIN Code D), use premiumunleaded gasoline with a postedoctane rating of 91 or higher. Youcan also use regular unleadedgasoline rated at 87 octane orhigher, but the vehicle's accelerationcould be slightly reduced, and aslight audible knocking noise,commonly referred to as sparkknock, might be heard. If the octaneis less than 87, a heavy knockingnoise might be heard when driving.
Black plate (50,1)Buick LaCrosse Owner Manual - 20129-50 Driving and OperatingIf this occurs, use a gasoline ratedat 87 octane or higher as soon aspossible. Otherwise, you coulddamage the engine. If heavyknocking is heard when usinggasoline rated at 87 octane orhigher, the engine needs service.Gasoline Specifications(U.S. and Canada Only)At a minimum, gasoline shouldmeet ASTM specification D 4814 inthe United States or CAN/CGSB‐3.5or 3.511 in Canada.Some gasolines contain anoctane-enhancing additive calledmethylcyclopentadienyl manganesetricarbonyl (MMT). We recommendagainst the use of gasolinescontaining MMT. See Fuel Additiveson page 9‑50 for additionalinformation.California FuelRequirementsIf the vehicle is certified to meetCalifornia Emissions Standards, it isdesigned to operate on fuels thatmeet California specifications. Seethe 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 might fail a smog‐check test.See Malfunction Indicator Lamp onpage 5‑16. If this occurs, return toyour authorized dealer for diagnosis.If it is determined that the conditionis caused by the type of fuel used,repairs might not be covered by thevehicle warranty.Fuels in ForeignCountriesNever use leaded gasoline or anyother fuel not recommended in theprevious text on fuel. Costly repairscaused by use of improper fuelwould not be covered by thevehicle warranty.To check the fuel availability, ask anauto club, or contact a major oilcompany that does business in thecountry where you will be driving.Fuel AdditivesTo provide cleaner air, all gasolinesin the United States are nowrequired to contain additives thathelp prevent engine and fuel systemdeposits from forming, allowing theemission control system to workproperly. In most cases, nothingshould have to be added to the fuel.However, some gasolines containonly the minimum amount ofadditive required to meet U.S.Environmental Protection Agency

To help keep fuelinjectors and intake valves cleanand avoid problems due to dirtyinjectors or valves, look for gasolinethat is advertised as TOP TIERDetergent Gasoline. Look for theTOP TIER label on the fuel pump toensure gasoline meets enhanceddetergency standards developed bythe auto companies. A list ofmarketers providing TOP TIERDetergent Gasoline can be found atwww.toptiergas.com.For customers who do not use TOPTIER Detergent Gasoline regularly,one bottle of GM Fuel SystemTreatment PLUS, added to the fueltank at every engine oil change,can help clean deposits from fuelinjectors and intake valves. GM FuelSystem Treatment PLUS is the onlygasoline additive recommended byGeneral Motors. It is available atyour dealer.Gasolines containing oxygenates,such as ethers and ethanol, andreformulated gasolines might beavailable in your area. Werecommend that you use thesegasolines, if they comply with thespecifications described earlier.However, E85 (85% ethanol) andother fuels containing more than15% ethanol must not be used invehicles that were not designed forthose fuels.Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.Some gasolines that are notreformulated for low emissionscan contain an octane-enhancing additive calledmethylcyclopentadienylmanganese tricarbonyl (MMT);ask the attendant where you buygasoline whether the fuel containsMMT. We recommend against theuse of such gasolines. Fuelscontaining MMT can reduce sparkplug life and affect emission controlsystem performance. Themalfunction indicator lamp mightturn on.

Black plate (54,1)Buick LaCrosse Owner Manual - 20129-54 Driving and OperatingTowingGeneral TowingInformationOnly use towing equipment that hasbeen designed for the vehicle.Contact your dealer or traileringdealer for assistance with preparingthe vehicle for towing a trailer.See the following trailer towinginformation in this section:.For information on driving whiletowing a trailer, see “DrivingCharacteristics andTowing Tips.”.For maximum vehicle and trailerweights, see “Trailer Towing.”.For information on equipment totow a trailer, see “TowingEquipment.”For information on towing a disabledvehicle, see Towing the Vehicle onpage 10‑94. For information ontowing the vehicle behind anothervehicle such as a motor home, seeRecreational Vehicle Towing onpage 10‑95.Driving Characteristicsand Towing Tips{WARNINGThe driver can lose control whenpulling a trailer if the correctequipment is not used or thevehicle is not driven properly.For example, if the trailer is tooheavy, the brakes may not workwell —or even at all. The driverand passengers could beseriously injured. The vehicle mayalso be damaged; the resultingrepairs would not be covered bythe vehicle warranty. Pull a traileronly if all the steps in this sectionhave been followed. Ask yourdealer for advice and informationabout towing a trailer with thevehicle.The vehicle can tow a trailer whenequipped with the proper trailertowing equipment. For traileringcapacity, see Trailer Towing (ExcepteAssist) on page 9‑57 or TrailerTowing (eAssist) on page 9‑59.Trailering changes handling,acceleration, braking, durability, andfuel economy. With the addedweight, the engine, transmission,wheel assemblies, and tires areforced to work harder and undergreater loads. The trailer also addswind resistance, increasing thepulling requirements. For safetrailering, correctly use the propertrailering equipment.The following information hasimportant trailering tips and rulesfor your safety and that of yourpassengers. Read this sectioncarefully before pulling a trailer.
Black plate (55,1)Buick LaCrosse Owner Manual - 2012Driving and Operating 9-55Pulling a TrailerHere are some important points:.There are many laws, includingspeed limit restrictions that applyto trailering. Check for legalrequirements..Do not tow a trailer at all duringthe first 1 600 km (1,000 mi) thenew vehicle is driven. Theengine, axle, or other parts couldbe damaged..During the first 800 km (500 mi)that a trailer is towed, do notdrive over 80 km/h (50 mph) anddo not make starts at full throttle.This reduces wear on thevehicle..The vehicle can tow in D (Drive).Use a lower gear if thetransmission shifts too often..Obey speed limit restrictions.Do not drive faster than themaximum posted speed fortrailers, or no more than90 km/h (55 mph), to reducewear on the vehicle.Driving with a TrailerTowing a trailer requires experience.Get familiar with handling andbraking with the added trailerweight. The vehicle is now longerand not as responsive as thevehicle is by itself.Check all trailer hitch parts andattachments, safety chains,electrical connectors, lamps, tires,and mirror adjustments. If the trailerhas electric brakes, start the vehicleand trailer moving and then applythe trailer brake controller by handto be sure the brakes are working.During the trip, check regularly tobe sure that the load is secure, andthe lamps and trailer brakes areworking properly.Towing with a Stability ControlSystemWhen towing, the sound of thestability control system might beheard. The system is reacting to thevehicle movement caused by thetrailer, which mainly occurs duringcornering. This is normal whentowing heavier trailers.Following DistanceStay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid situationsthat require heavy braking andsudden turns.PassingMore passing distance is neededwhen towing a trailer. Because therig is longer, it is necessary to gofarther beyond the passed vehiclebefore returning to the lane.Backing UpHold 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.
Black plate (56,1)Buick LaCrosse Owner Manual - 20129-56 Driving and OperatingMaking TurnsNotice: Making very sharp turnswhile trailering could cause thetrailer to come in contact with thevehicle. The vehicle could bedamaged. Avoid making verysharp turns while trailering.When turning with a trailer, makewider turns than normal so thetrailer will not strike soft shoulders,curbs, road signs, trees, or otherobjects. Use the turn signal well inadvance and avoid jerky or suddenmaneuvers.Turn Signals when Towing aTrailerThe turn signal indicators on theinstrument panel flash wheneversignaling a turn or lane change.Properly hooked up, the trailerlamps also flash, telling otherdrivers the vehicle is turning,changing lanes, or stopping.When towing a trailer, the arrows onthe instrument panel flash for turnseven if the bulbs on the trailer areburned out. Check occasionally tobe sure the trailer bulbs are stillworking.Driving on GradesReduce speed and shift to a lowergear before starting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might have to be used somuch that they would get hot and nolonger work well.The vehicle can tow in D (Drive).Use a lower gear if the transmissionshifts too often.When towing at high altitude onsteep uphill grades, engine coolantboils at a lower temperature than atnormal altitudes. If the engine isturned off immediately after towingat high altitude on steep uphillgrades, the vehicle could showsigns similar to engine overheating.To avoid this, let the engine runwhile parked, preferably on levelground, with the transmission inP (Park) for a few minutes beforeturning the engine off. If theoverheat warning comes on, seeEngine Overheating on page 10‑19.Parking on Hills{WARNINGParking 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.
Black plate (57,1)Buick LaCrosse Owner Manual - 2012Driving and Operating 9-573. When the wheel chocks are inplace, release the brake pedaluntil 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 Hill1. Apply and hold the brake pedalwhile you:1.1. Start the engine.1.2. Shift into a gear.1.3. Release the parking brake.2. Let up on the brake pedal.3. Drive slowly until the trailer isclear of the chocks.4. Stop and have someone pick upand store the chocks.Maintenance when TrailerTowingThe vehicle needs service moreoften when pulling a trailer. See theMaintenance Schedule onpage 11‑3. Things that areespecially important in traileroperation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system, andbrake system. Inspect these beforeand during the trip.Check periodically to see that allhitch nuts and bolts are tight.Engine Cooling when TrailerTowingThe cooling system may temporarilyoverheat during severe operatingconditions. See Engine Overheatingon page 10‑19.Trailer Towing(Except eAssist)Before pulling a trailer, there arethree important considerations thathave to do with weight:.The weight of the trailer..The weight of the trailer tongue..The total weight on yourvehicle's tires.Weight of the TrailerHow heavy can a trailer safely be?For a vehicle with a V6 engine, itshould never weigh more than454 kg (1,000 lbs). But even thatcan be too heavy.It depends on how the rig is used.For example, speed, altitude, roadgrades, outside temperature, andhow 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.
Black plate (58,1)Buick LaCrosse Owner Manual - 20129-58 Driving and OperatingSee “Weight of the Trailer Tongue”later in this section for moreinformation.Maximum trailer weight is calculatedassuming only the driver is in thetow vehicle and it has all therequired trailering equipment.The weight of additional optionalequipment, passengers, andcargo in the tow vehicle must besubtracted from the maximumtrailer weight.Ask your dealer for traileringinformation or advice, or write us atour Customer Assistance Offices.See Customer Assistance Offices(U.S. and Canada) on page 13‑4orCustomer Assistance Offices(Mexico) on page 13‑5for moreinformation.Weight of the Trailer TongueThe tongue load (A) of any trailer isan important weight to measurebecause it affects the total grossweight of the vehicle. The GrossVehicle Weight (GVW) includes thecurb 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 9‑10for more information.The trailer tongue (A) should weigh10 to 15 percent of the total loadedtrailer weight (B).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.
Black plate (59,1)Buick LaCrosse Owner Manual - 2012Driving and Operating 9-59Total Weight on Your Vehicle'sTiresBe sure the vehicle's tires areinflated to the upper limit for coldtires. These numbers can be foundon the Information label. SeeVehicle Load Limits on page 9‑10.Make sure not to go over theGVW limit for the vehicle, includingthe weight of the trailer tongue.Trailer Towing (eAssist)The vehicle is neither designed norintended to tow a trailer.Towing EquipmentHitchesUse the correct hitch equipment.See your dealer or a hitch dealerfor assistance..The rear bumper on the vehicleis 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 thereare, seal the holes when thehitch is removed. If the holes arenot sealed, dirt, water, anddeadly carbon monoxide (CO)from the exhaust can get into thevehicle. See Engine Exhaust onpage 9‑28.Safety ChainsAlways 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 BrakesDoes 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.

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 10‑12..Always dispose of engine oilproperly. See “What to Do withUsed Oil”in this section.
Black plate (10,1)Buick LaCrosse Owner Manual - 201210-10 Vehicle CareChecking Engine OilIt 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 yellowloop. See Engine CompartmentOverview on page 10‑6for thelocation of the engine 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.2. Pull out the dipstick and clean itwith a paper towel or cloth, thenpush it back in all the way.Remove it again, keeping thetip down, and check the level.When to Add Engine OilIf 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 ofwhat kind of oil to use. For engineoil crankcase capacity, seeCapacities and Specifications onpage 12‑2.Notice: Do not add too much oil.Oil levels 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 10‑6for 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 OilSelecting the right engine oildepends on both the proper oilspecification and viscosity grade.See Recommended Fluids andLubricants on page 11‑14.SpecificationUse and ask for licensed engine oilswith the dexos1™approvedcertification mark. Engine oilsmeeting the requirements for thevehicle should have the dexos1
Black plate (11,1)Buick LaCrosse Owner Manual - 2012Vehicle Care 10-11approved certification mark. Thiscertification mark indicates that theoil has been approved to the dexos1specification.Notice: Failure to use therecommended engine oil orequivalent can result in enginedamage not covered by thevehicle warranty. Check with yourdealer or service provider onwhether the oil is approved to thedexos1 specification.Viscosity GradeSAE 5W‐30 is the best viscositygrade for the vehicle. Do not useother viscosity grade oils such asSAE 10W‐30, 10W‐40, or 20W‐50.If in an area of extreme cold, wherethe temperature falls below −20°F(−29°C), an SAE 0W‐30 oil shouldbe used. An oil of this viscositygrade will provide easier coldstarting for the engine at extremelylow temperatures. When selectingan oil of the appropriate viscositygrade, always select an oil thatmeets the dexos1 specification orequivalent. See “Specification”formore information.Engine Oil Additives/EngineOil FlushesDo 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 OilUsed 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 yourskin 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.
Black plate (12,1)Buick LaCrosse Owner Manual - 201210-12 Vehicle CareEngine Oil Life SystemWhen to Change Engine OilThis 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. Forthe 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 5‑35.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 mustbe reset. 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 theproper level.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 SystemReset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. To reset thesystem:1. Turn the ignition to ON/RUN withthe engine off.2. Press the DIC MENU button onthe turn signal lever to enter theVehicle Information Menu. Usethe thumbwheel to scroll throughthe menu items until you reachREMAINING OIL LIFE.3. Press the SET/CLR button toreset the oil life at 100%.4. Turn the ignition to LOCK/OFF.
Black plate (13,1)Buick LaCrosse Owner Manual - 2012Vehicle Care 10-13The system is reset when theCHANGE ENGINE OIL SOONmessage is off and the REMAININGOIL LIFE 100% message isdisplayed.If the CHANGE ENGINE OILmessage comes back on when thevehicle is started, the engine oil lifesystem has not been reset. Repeatthe procedure.Automatic TransmissionFluidHow to Check AutomaticTransmission FluidIt is not necessary to check thetransmission fluid level.A transmission fluid leak is the onlyreason for fluid loss. If a leakoccurs, take the vehicle to yourdealer service department and haveit repaired as soon as possible.There is a special procedure forchecking and changing thetransmission fluid.

Have thesystem inspected and repaired.How to Check Power SteeringFluidCheck the level after the vehicle hasbeen driven for at least 20 minutesso the fluid is warm.To check the power steering fluid:1. Turn the ignition to LOCK/OFFand let the engine compartmentcool down.2. Wipe the cap and the top of thereservoir clean.3. Unscrew the cap and pull itstraight up.4. Wipe the dipstick with aclean rag.5. Replace the cap and completelytighten it.6. Remove the cap again and lookat the fluid level on the dipstick.When the engine is hot, the levelshould be at the hot MAX level.When the engine is cold, the fluidlevel should be between MIN andMAX on the dipstick.What to UseTo determine what kind of fluid touse, see Recommended Fluids andLubricants on page 11‑14. Alwaysuse the proper fluid.
Black plate (22,1)Buick LaCrosse Owner Manual - 201210-22 Vehicle CareWasher FluidWhat to UseWhen windshield washer fluid isneeded, be sure to read themanufacturer's instructions beforeuse. If operating the vehicle in anarea where the temperature may fallbelow freezing, use a fluid that hassufficient protection againstfreezing.Adding Washer FluidOpen the cap with the washersymbol on it. Add washer fluid untilthe tank is full. See EngineCompartment Overview onpage 10‑6for reservoir location.Notice.When using concentratedwasher fluid, follow themanufacturer's instructionsfor adding water..Do not mix water withready-to-use washer fluid.Water can cause the solutionto freeze and damage thewasher fluid tank and otherparts of the washer system.Also, water does not clean aswell as washer fluid..Fill the washer fluid tank onlythree-quarters full when it isvery cold. This allows forfluid expansion if freezingoccurs, which could damagethe tank if it iscompletely full..Do not use engine coolant(antifreeze) in the windshieldwasher. It can damage thewindshield washer systemand paint.BrakesThis vehicle has disc brakes.Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or beheard all the time the vehicle ismoving, except when applying thebrake pedal firmly.{WARNINGThe 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.Notice: Continuing to drive withworn-out brake pads could resultin costly brake repair.
Black plate (23,1)Buick LaCrosse Owner Manual - 2012Vehicle Care 10-23Some 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 in Capacities andSpecifications on page 12‑2.Brake linings should always bereplaced as complete axle sets.Brake Pedal TravelSee 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 AdjustmentEvery time the brakes are applied,with or without the vehicle moving,the brakes adjust for wear.Replacing Brake System PartsThe braking system on a vehicle iscomplex. Its many parts have to beof top quality and work well togetherif 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 partsare installed.Brake FluidThe brake master cylinder reservoiris filled with DOT 3 brake fluid asindicated on the reservoir cap. SeeEngine Compartment Overview onpage 10‑6for the location of thereservoir.There are only two reasons why thebrake fluid level in the reservoirmight go down:.The brake fluid level goes downbecause of normal brake liningwear. When new linings areinstalled, the fluid level goesback up.
Black plate (24,1)Buick LaCrosse Owner Manual - 201210-24 Vehicle Care.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.{WARNINGIf 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 workis done 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 AddUse only new DOT 3 brake fluidfrom a sealed container. SeeRecommended Fluids andLubricants on page 11‑14.Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it. Thishelps keep dirt from entering thereservoir.{WARNINGWith the wrong kind of fluid in thebrake hydraulic system, thebrakes might not work well. Thiscould cause a crash. Always usethe proper brake fluid.Notice.Using the wrong fluidcan badly damage brakehydraulic system parts. Forexample, just a few drops ofmineral-based oil, such asengine oil, in the brakehydraulic system candamage brake hydraulicsystem parts so badly thatthey will have to be replaced.Do not let someone put inthe wrong kind of fluid..If brake fluid is spilled on thevehicle's painted surfaces,the paint finish can bedamaged.

Do not forget the compactspare tire, if the vehicle has one.The compact spare should be at420 kPa (60 psi). For additionalinformation regarding thecompact spare tire, seeCompact Spare Tire onpage 10‑89.How to CheckUse 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.Re‐check the tire pressure withthe tire gauge.Return the valve caps on thevalve stems to prevent leaksand keep out dirt and moisture.
Black plate (53,1)Buick LaCrosse Owner Manual - 2012Vehicle Care 10-53Tire 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 tirepressure telltale when one or moreof your tires is significantly under‐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 10‑54 foradditional information.

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 lightlocated on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the tire 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.For additional information anddetails about the DIC operation anddisplays see Driver InformationCenter (DIC) on page 5‑25.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.A Tire and Loading Informationlabel, attached to your vehicle,shows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. See Vehicle LoadLimits on page 9‑10, for an exampleof the Tire and Loading Informationlabel and its location.

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 beenreplaced with the spare tire.The spare tire does not have aTPMS 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 successfullyafter rotating the tires.

Multiple conditionsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place.Tires will typically need to bereplaced due to wear beforethey may need to be replaceddue to age. Consult the tiremanufacturer for more informationon when tires should be replaced.Vehicle StorageTires 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 befree 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.
Black plate (60,1)Buick LaCrosse Owner Manual - 201210-60 Vehicle CareBuying 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 sameTPC Spec rating.GM's exclusive TPC Specsystem considers over a dozencritical specifications that impactthe 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 10‑46 foradditional information.GM recommends replacing allthe tires at the same time.Uniform tread depth on alltires will help to maintain theperformance of the vehicle.Braking and handlingperformance may be adverselyaffected if all the tires are notreplaced at the same time. SeeTire Inspection on page 10‑57and Tire Rotation on page 10‑58for information on proper tirerotation.{WARNINGTires could explode duringimproper service. Attempting tomount or dismount a tire couldcause injury or death. Only your(Continued)WARNING (Continued)dealer or authorized tire servicecenter should mount or dismountthe tires.{WARNINGMixing 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.{WARNINGUsing bias-ply tires on thevehicle may cause the wheelrim flanges to develop cracksafter many miles of driving.(Continued)
Black plate (61,1)Buick LaCrosse Owner Manual - 2012Vehicle Care 10-61WARNING (Continued)A tire and/or wheel could failsuddenly and cause a crash.Use only radial-ply tires withthe wheels on the vehicle.If the vehicle tires must bereplaced with a tire that does nothave a TPC Spec number, makesure they are the same size,load range, speed rating, andconstruction (radial) as theoriginal tires.Vehicles that have a tirepressure monitoring systemcould give an inaccurate low‐pressure warning if non‐TPCSpec rated tires are installed.See Tire Pressure MonitorSystem on page 10‑53.The Tire and LoadingInformation label indicates theoriginal equipment tires on thevehicle. See Vehicle Load Limitson page 9‑10 for the labellocation and more informationabout the Tire and LoadingInformation label.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 rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, tractioncontrol, and electronic stabilitycontrol, the performance of thesesystems can also be affected.{WARNINGIf 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.See Buying New Tires onpage 10‑60 and Accessories andModifications on page 10‑3foradditional information.
Black plate (62,1)Buick LaCrosse Owner Manual - 201210-62 Vehicle CareUniform Tire QualityGradingQuality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width.For example:Treadwear 200 Traction AATemperature AThe following information relatesto the system developed by theUnited States National HighwayTraffic Safety Administration(NHTSA), which grades tiresby treadwear, traction, andtemperature performance. Thisapplies only to vehicles sold inthe United States. The gradesare molded on the sidewalls ofmost passenger car tires. TheUniform Tire Quality Grading(UTQG) system does not applyto deep tread, winter-typesnow tires, space-saver, ortemporary use spare tires,tires with nominal rim diametersof 10 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.TreadwearThe treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government testcourse. For example, a tiregraded 150 would wear one anda half (1½) times as well on thegovernment 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 –AA, A, B, CThe 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.
Black plate (63,1)Buick LaCrosse Owner Manual - 2012Vehicle Care 10-63Warning: The traction gradeassigned to this tire is based onstraight-ahead braking tractiontests, and does not includeacceleration, cornering,hydroplaning, or peak tractioncharacteristics.Temperature –A, B, CThe 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 ofperformance on the laboratorytest wheel than the minimumrequired by law. Warning: Thetemperature grade for this tire isestablished for a tire that isproperly inflated and notoverloaded. 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 balancingwill not be necessary on a regularbasis. However, check thealignment if there is unusual tirewear or if the vehicle is pulling toone side or the other.If the vehicle vibrates when drivingon a smooth road, the tires andwheels might need to berebalanced. See your dealer forproper 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 theone it replaces.
Black plate (64,1)Buick LaCrosse Owner Manual - 201210-64 Vehicle CareReplace wheels, wheel bolts, wheelnuts, or Tire Pressure MonitorSystem (TPMS) sensors with newGM original equipment parts.{WARNINGUsing 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.Notice: The wrong wheel canalso cause problems with bearinglife, brake cooling, speedometeror odometer calibration,headlamp aim, bumper height,vehicle ground clearance, and tireor tire chain clearance to thebody and chassis.See If a Tire Goes Flat onpage 10‑64 for more information.Used Replacement Wheels{WARNINGReplacing 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{WARNINGDo 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 vehicle(Continued)WARNING (Continued)parts. 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.To avoid vehicle damage, driveslow and 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 out,especially if the tires are maintainedproperly. See Tires on page 10‑44.If air goes out of a tire, it is muchmore likely to leak out slowly.
Black plate (65,1)Buick LaCrosse Owner Manual - 2012Vehicle Care 10-65But if there is ever a blowout, hereare a few tips about what to expectand 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.{WARNINGDriving on a flat tire will causepermanent damage to the tire.Re-inflating a tire after it hasbeen driven on while severelyunderinflated or flat may cause ablowout and a serious crash.Never attempt to re-inflate a tirethat has been driven on whileseverely underinflated or flat.Have your dealer or an authorizedtire service center repair orreplace the flat tire as soonas possible.{WARNINGLifting a vehicle and gettingunder it to do maintenance orrepairs is dangerous without theappropriate safety equipment andtraining. If a jack is provided withthe vehicle, it is designed only forchanging a flat tire. If it is used foranything else, you or others couldbe badly injured or killed if thevehicle slips off the jack.

Poorly performed collisionrepairs diminish the vehicle resalevalue, and safety performance canbe compromised in subsequentcollisions.Collision PartsGenuine 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 theGM New 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 ofthese 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 arealso available. These are made bycompanies other than GM and maynot have been tested for the vehicle.
Black plate (15,1)Buick LaCrosse Owner Manual - 2012Customer Information 13-15As 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 FacilityGM 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 collisionrepair center that has GM-trainedtechnicians and comparableequipment.Insuring the VehicleProtect your investment in theGM vehicle 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 compensationfor damage repairs by usingaftermarket collision parts. Someinsurance companies will notspecify aftermarket collision parts.When purchasing insurance, werecommend that you ensure thatthe vehicle will be repaired withGM original equipment collisionparts. If such insurance coverageis not available 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 OccursIf 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 apolice officer.Give only the necessary informationto police and other parties involvedin the crash.For emergency towing seeRoadside Assistance Program (U.S.and Canada) on page 13‑7orRoadside Assistance Program(Mexico) on page 13‑9.

Black plate (19,1)Buick LaCrosse Owner Manual - 2012Customer Information 13-19Event Data RecordersThis vehicle has an Event DataRecorder (EDR). The main purposeof an EDR is to record, in certaincrash or near crash-like situations,such as an airbag deployment orhitting a road obstacle, data thatwill assist in understanding how avehicle's systems performed. TheEDR is designed to record datarelated to vehicle dynamics andsafety systems for a short period oftime, typically 30 seconds or less.The EDR in this vehicle is designedto record such data as:.How various systems in thevehicle were operating..Whether or not the driver andpassenger safety belts werebuckled/fastened..How far, if at all, the driver waspressing the accelerator and/orbrake pedal..How fast the vehicle wastraveling.This data can help provide a betterunderstanding of the circumstancesin which crashes and injuries occur.Important: EDR data is recordedby the vehicle only if a non-trivialcrash situation occurs; no data isrecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age, andcrash location) is recorded.However, other parties, such as lawenforcement, could combine theEDR data with the type ofpersonally identifying data routinelyacquired 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.
