Once a low or high tire pressure condition is detected, the TPM system will display the CHECK TIRE MESSAGE each time the engine is started, until the tire(s) are set to the correct inflation pressure. The Tire-Loading Information Label, which is located on the rear edge of the driver's door, shows the correct inflation pressure for thetires on your vehicle. The TPM system also allows the driver to check the air pressure status of each road tire using the Driver Information Center (DIC). Each tire's air pressure will be listed individually, in the following order: LF (left front or driver's side front tire), RF (right front or passenger's side front tire), RR (right rear or passenger's side rear tire) and LR (left rear or driver's side rear tire). See Inflation -- Tire Pressure on page 5-61 for information regarding correct tire inflation. Also, see Driver Information Center (DIC) on page 3-57 for information on the DIC controls and displays. If the DIC display doesn't show tire pressures or the SERVICE TPM SYSTEM message appears, see your dealer for service. The TPM system may not work properly while the compact spare tire is installed. Anytime you replace one or more tires or rotate your tires, the TPM system will need to be reset. A special tool is needed to reset the sensor identification codes. See your dealer for service. Your vehicle was delivered from the factory with aluminum valve stem caps. If you ever have to replace the valve stem caps on your vehicle, you should replace them with aluminum or plastic caps. The TPM system can alert you about a low or high tire pressure condition, but it doesn't replace normal tire maintenance. See Tires on page 5-60. 5-63
