To reset (calibrate) the system: 1. Turn the ignition switch to RUN. 2. Press the GAGE INFO button on the DIC until TIRE PRESSURE appears on the display. 3. Press and hold the DIC RESET button for about five seconds. After five seconds, the display will show TIRE PRESSURE RESET. If TIRE PRESSURE RESET does not appear in the display after about five seconds retry the process. If it does not work after two tries, see your dealer for service. After you release the DIC RESET button, TIRE PRESSURE NORMAL will appear in the display. The system completes the calibration process during driving. Calibration time can take 45 to 90 minutes, depending on your driving habits. After the system has been calibrated, the system will alert the driver that a tire is low, up to a maximum speed of 65 mph (105 km/h). Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 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's Time for New Tires" and "Wheel Replacement" later in this section 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 Services" in the Index for scheduled rotation intervals. When rotating your tires, always use the correct rotation pattern shown here. 6-47
