Don't reset the check tire pressure system without first correcting the cause of the problem and checking and adjusting the pressure in all four tires. If you reset the system when the tire pressures are incorrect, the check tire pressure system will not work properly and may not alert you when a tire is low or high. 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. Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (1 0 000 to 13 000 km). Any time you notice unusual wear rotate your tires as soon aspossible and check wheel alignment.Also check for damagedtires or wheels. SeeWhen It Is Time for New Tires on page 5-65 and Wheel Replacementon page 5-68for 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 "Part A: Scheduled Maintenance Services," in Section 6, for scheduled rotation intervals. 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 yourdriving habits. Afterthe system has been calibrated, the system will alertthe driver that a tire is low, up to a maximum speed of 65 mph (105 km/h). When rotating your tires, always use the correct rotation pattern shown here. 5-64
