WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoringsystem measures the vehicle'stire pressures. A warning lampilluminates if one or more tires aresignificantly underinflated or if there is asystem malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW
WARNING: Under-inflation is themost common cause of tire failures andmay result in severe tire cracking, treadseparation or blowout, with unexpectedloss of vehicle control and increased riskof injury. Under-inflation increasessidewall flexing and rolling resistance,resulting in heat buildup and internaldamage to the tire. It also may result inunnecessary tire stress, irregular wear,loss of vehicle control and accidents. Atire can lose up to half of its air pressureand not appear to be flat!
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance CertificationLabel (on the door hinge pillar,door-latch post or the door edge thatmeets the door-latch post, next to thedriver seat) or the Tire Label on theB-Pillar or the edge of the driver door.
Each tire, including the spare (if provided),should be checked monthly when cold andinflated to the inflation pressurerecommended by the vehicle manufactureron the vehicle placard or tire inflationpressure label. (If your vehicle has tires ofa different size than the size indicated onthe vehicle placard or tire inflation pressurelabel, you should determine the proper tireinflation pressure for those tires).
As an added safety feature, your vehiclehas been equipped with a Tire PressureMonitoring System (TPMS) thatilluminates a low tire pressure telltalewhen one or more of your tires issignificantly under-inflated. Accordingly,when the low tire pressure telltaleilluminates, you should stop and checkyour tires as soon as possible, and inflatethem to the proper pressure. Driving on asignificantly under-inflated tire causes thetire to overheat and can lead to tire failure.Under-inflation also reduces fuel efficiencyand tire tread life, and may affect thevehicle’s handling and stopping ability.
Please note that the TPMS is not asubstitute for proper tire maintenance, andit is the driver’s responsibility to maintaincorrect tire pressure, even if under-inflationhas not reached the level to triggerillumination of the TPMS low tire pressuretelltale.
Your vehicle has also been equipped witha TPMS malfunction indicator to indicatewhen the system 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 then remaincontinuously illuminated. This sequencewill continue upon subsequent vehiclestart-ups as long as the malfunction exists.

CHANGING A FLAT TIRE
If you get a flat tire when driving, do notapply the brake heavily. Instead, graduallydecrease your speed, hold the steeringwheel firmly and slowly move to a safeplace on the side of the road.
Have the flat serviced by an authorizeddealer to prevent damage to the systemsensors. See Tire Pressure MonitoringSystem (page 452). Replace the spare tirewith a road tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the systemsensor for damage.
Note:Only use tire sealants in roadsideemergencies as they may cause damage tothe tire pressure monitoring system sensor.
Note:The tire pressure monitoring systemindicator light illuminates when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheels withtire pressure monitoring sensors must bemounted on this vehicle.
Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increasedrisk of loss of vehicle control, injury ordeath.
If you have a dissimilar spare wheel andtire, then it is intended for temporary useonly. This means that if you need to use it,you should replace it as soon as possiblewith a road wheel and tire assembly thatis the same size and type as the road tiresand wheels that were originally provided.If the dissimilar spare tire or wheel isdamaged, it should be replaced rather thanrepaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tireassembly that is different in brand, size orappearance from the other road tires andwheels on your vehicle.
Full-size dissimilar spare
When driving with the full-size dissimilarspare wheel and tire assembly, do not:
•Exceed 70 mph (113 km/h).
•Use more than one dissimilar sparewheel and tire assembly at a time.
•Use snow chains on the end of thevehicle with the dissimilar spare wheeland tire assembly.
When driving with the full-size dissimilarspare wheel and tire assembly, it isrecommended that you do not:
•Exceed 50 mph (80 km/h) infour-wheel drive.
•Engage four-wheel drive unless thevehicle is stationary.
•Use four-wheel drive on dry pavement.
Using a dissimilar spare wheel and tireassembly can compromise theeffectiveness of the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
•Wet weather driving capability.
•Four-wheel driving capability.
When driving with the full-size dissimilarspare wheel and tire assembly additionalcaution should be given to:
•Towing a trailer.
•Driving vehicles equipped with acamper body.
•Driving vehicles with a load on thecargo rack.

Drive cautiously when using a full-sizedissimilar spare wheel and tire assemblyand seek service as soon as possible.
Location of the Spare Tire andTools
The spare tire is located under the vehicle,just forward of the rear bumper. The jack,swivel wrench and lug wrench are in thefollowing locations:
LocationItem
Under the vehicle, just forward of the rearbumperSpare tire
Under the access panel located in the floorcompartment behind the rear seatJack and tool kit bag
Tire Change Procedure
WARNING: Only use replacementtires and wheels that are the same size,load index, speed rating, and type asthose originally provided for your vehicle.The recommended tire and wheel sizescan be found on the Tire Label on thedriver side door frame or the edge of thedriver door. If this information is notfound in those locations, or for additionaloptions, contact your authorized dealer.Use of any tire or wheel notrecommended, could affect the safetyand performance of your vehicle, whichcould result in an increased risk of lossof vehicle control, vehicle rollover,personal injury and death.
WARNING: To help prevent yourvehicle from moving when changing awheel, shift the transmission into park(P), set the parking brake and use anappropriate block or wheel chock tosecure the wheel diagonally opposite tothe wheel being changed. For example,when changing the front left wheel,place an appropriate block or wheelchock on the right rear wheel.
WARNING: Only use the jackprovided as original equipment with yourvehicle.
WARNING: Switch off the runningboards before jacking or placing anyobject under your vehicle. Never placeyour hand between the extended runningboard and your vehicle. A moving runningboard may cause injury.
WARNING: Only use the sparewheel carrier to stow wheels providedwith your vehicle.
WARNING: Ensure screwthread isadequately lubricated before use.
WARNING: Switch the ignition offand apply the parking brake. If yourvehicle has a manual transmission, shiftinto first or reverse gear. If your vehiclehas an automatic transmission, shift intopark (P).
WARNING: Only use the specifiedjacking points. If you use any otherlocations you could damage vehiclecomponents, such as brake lines.

WHEEL NUTS
WARNING: When you install awheel, always remove any corrosion, dirtor foreign materials present on themounting surfaces of the wheel or thesurface of the wheel hub, brake drum orbrake disc that contacts the wheel. Makesure to secure any fasteners that attachthe rotor to the hub so they do notinterfere with the mounting surfaces ofthe wheel. Installing wheels withoutcorrect metal-to-metal contact at thewheel mounting surfaces can cause thewheel nuts to loosen and the wheel tocome off while your vehicle is in motion,resulting in loss of vehicle control,personal injury or death.
