Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. If the TPM system detects low tire pressure, below 25 psi (172 kPa), or high tire pressure, above 38 psi (262 kPa), a message, CHECK TIRE PRESSURE, will appear on the Driver Information Center (DIC) display. By pressing the INFO button, the DIC screen will show which tire(s) has the low or high pressure condition. See "Inflation -- Tire Pressure" in the Index for information regarding correct tire inflation. If a tire is low, you should stop as soon as possible and check all your tires for damage. If a tire is flat, see "If a Tire Goes Flat" in the Index. The Tire-Loading Information Label, which is located on the rear edge of the driver's door, shows the correct inflation pressure for the tires 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" in the Index for information regarding correct tire inflation. Also, see "Driver Information Center (DIC)" in the Index 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. The TPM system can alert you about a low or high tire pressure condition, but it doesn't replace normal tire maintenance. See "Tires" in the Index. NOTICE: Do not use a tire sealant if your vehicle is equipped with Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors. 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. 6-51
