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 repeat the procedure. 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). 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 5-64 and Wheel Replacement on page 5-67 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 Part A: Scheduled Maintenance Services on page 6-4, for scheduled rotation intervals. Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). When rotating your tires, always use the correct rotation pattern shown here. Don't include the compact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. 5-63
