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 5-65 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 does not 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 does not replace normal tire maintenance. See Tires on page 5-57. Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-70 and Wheel Replacement on page 5-73 for more information. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Scheduled Maintenance on page 6-4. When rotating your tires, always use the correct rotation pattern shown here. Do not include the compact spare tire, if your vehicle has one, in your tire rotation. 5-69
