WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
Tire Pressure Monitoring System withIndividual Tire Pressure Display
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.

When the malfunction indicator isilluminated, the system may not be ableto detect or signal low tire pressure asintended. TPMS malfunctions may occurfor a variety of reasons, including theinstallation of replacement or alternatetires or wheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or more tires orwheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to functionproperly.

TIRE PRESSURE MONITORING
SYSTEM PRECAUTIONS
WARNING: The tire pressuremonitoring system is not a substitute formanually checking tire pressures. Youshould periodically check tire pressuresusing a pressure gauge. Failure tocorrectly maintain tire pressures couldincrease the risk of tire failure, loss ofcontrol, vehicle rollover and personalinjury.
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge. Failureto follow this instruction could result inpersonal injury or death.
Note:The use of tire sealants can damagethe tire pressure monitoring system.
Note:If the tire pressure monitor sensorbecomes damaged it may not function.
TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS
When the outside temperature dropssignificantly, the tire pressure coulddecrease and activate the low tire pressurewarning lamp.
The warning lamp could also illuminatewhen you use a spare wheel, or tire sealantfrom the inflator kit.
Note:Regularly checking the vehicle tirepressures can reduce the possibility for thewarning lamp to illuminate due to outsideair temperature changes.
Note:After you inflate the tires to therecommended pressure it could take up totwo minutes of driving over 20 mph(32 km/h) for the warning indicator to turnoff.

CHANGING A FLAT TIRE -
EXCLUDING: RAPTOR
Note:You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem 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 wheelsequipped with tire pressure monitoringsensors must be mounted on the vehicle.
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 your flat serviced by an authorizeddealer in order to prevent damage to thetire pressure monitoring system sensors.Replace the spare tire with a road tire assoon as possible. During repairing orreplacing of the flat tire, have theauthorized dealer inspect the tire pressuremonitoring system sensor for damage.
Tire Change Procedure
WARNING: Failure to follow theseguidelines could result in an increasedrisk of loss of vehicle control, injury ordeath.
WARNING: Do not get under avehicle that is supported by a jack.
WARNING: The jack supplied withthis vehicle is only intended for changinga flat tire in an emergency. Do notattempt to do any other work on yourvehicle when it is supported by the jack,as your vehicle could slip off the jack.Failure to follow this instruction couldresult in personal injury or 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: Only use the specifiedjacking points. If you use any otherlocations you could damage vehiclecomponents, such as brake lines.
WARNING: Never place anythingbetween the vehicle jack and yourvehicle.
WARNING: Never place anythingbetween the vehicle jack and the ground.
WARNING: Do not attempt tochange a tire on the side of the vehicleclose to moving traffic. Pull far enoughoff the road to not obstruct the flow oftraffic and avoid the danger of being hitwhen operating the jack or changing thewheel.
WARNING: Always fully apply theparking brake. Failure to follow thisinstruction could result in personal injuryor death.
WARNING: The jack should beused on level firm ground whereverpossible.

WARNING: It is recommended thatthe wheels of the vehicle be chocked,and that no person should remain in avehicle that is being jacked.
Note:Make sure all passengers are out ofyour vehicle.
Note:Jack at the specified locations toavoid damage to the vehicle.
Note:No maintenance or additionallubrication of your jack is required over theservice life of your vehicle.
1.Park the vehicle on a level, firm surfaceand activate the hazard flashers.
2.Apply the parking brake, and place thetransmission in park (P) for anautomatic transmission or reverse (R)for a manual transmission and turn theengine off.
3.Block the wheel diagonally opposite ofthe flat tire. For example, if the leftfront is flat, block the right rear wheel.
4.Find the jack and tool kit in the reartrunk of the vehicle. Turn the jackretainer counterclockwise to removethe jack and jack extension block.
5.Remove the tool bag.

6.Remove the lug wrench from the toolbag. Turn the spare tire fastenerscounterclockwise starting with thelowest first, and remove the spare tirefrom the rear of the vehicle.
Note:Insert the wheel lock key into thewheel lock nut before using the lug wrenchto loosen the lock nut.
Note:Do not lay the wheel face down onthe ground, as there is a risk of scratchingor marring the wheel if laid down on anuneven surface.
7.Loosen each road wheel nut a half aturn counterclockwise, do not removethem until the flat tire is raised off theground.
8.When you are changing a flat front tire,connect the extension block to the jackloadrest using the wing bolt as shown.Connect the jack handle to the jack,and use the lug nut wrench to operatethe jack.
9.Do not use the extension block whenyou are changing a flat tire on the rearaxle of the vehicle. Assemble the jackhandle using the extensions as shownto operate the jack when placing underthe rear axle.
