The tire pressure monitoring systemmeasures pressure in your road tires andsends the tire pressure readings to yourvehicle. You can view the tire pressurereadings through the information display.See General Information (page 98).Thelow tire pressure warning light will turn onif the tire pressure is significantly low. Oncethe light is illuminated, your tires areunder-inflated and need to be inflated tothe manufacturer’s recommended tirepressure. Even if the light turns on and ashort time later turns off, your tire pressurestill needs to be checked.
When Your Temporary Spare Tire isInstalled
When one of your road tires needs to bereplaced with the temporary spare, thesystem will continue to identify an issue toremind you that the damaged road wheeland tire assembly needs to be repaired andput back on your vehicle.
To restore the full function of the tirepressure monitoring system, have thedamaged road wheel and tire assemblyrepaired and remounted on your vehicle.
When You Believe Your System is NotOperating Properly
The main function of the tire pressuremonitoring system is to warn you whenyour tires need air. It can also warn you inthe event the system is no longer capableof functioning as intended. See thefollowing chart for information concerningyour tire pressure monitoring system:

How Temperature Affects Your TirePressure
The tire pressure monitoring systemmonitors tire pressure in each pneumatictire. While driving in a normal manner, atypical passenger tire inflation pressurecould increase about 2–4 psi (14–28 kPa)from a cold start situation. If the vehicle isstationary overnight with the outsidetemperature significantly lower than thedaytime temperature, the tire pressurecould decrease about 3 psi (21 kPa) for adrop of 30°F (17°C) in ambienttemperature. This lower pressure valuecould be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflationpressure and activate the system warninglight for low tire pressure. If the low tirepressure warning light is on, visually checkeach tire to verify that no tire is flat. If oneor more tires are flat, repair as necessary.Check the air pressure in the road tires. Ifany tire is under-inflated, carefully drivethe vehicle to the nearest location whereair can be added to the tires. Inflate all thetires to the recommended inflationpressure.
CHANGING A ROAD WHEEL (IF
EQUIPPED)
WARNING: If the tire pressuremonitor sensor becomes damaged itmay not function.
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 a flat serviced by an authorizeddealer in order to prevent damage to thetire pressure monitoring system sensors.See Tire Pressure Monitoring System(page 326). Replace the spare tire with aroad tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the tirepressure monitoring system sensor fordamage.
Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increasedrisk of loss of vehicle control, injury ordeath.
