To reset (calibrate) the system: The tire inflation monitor system can be reset two ways. With the ignition position at ON, pull the interior lamps control to the ON and OFF settings three times. It can also be reset through the radio using the following steps: 1. Turn the ignition to ACC or ON and turn the radio off. 2. Press and hold the TUNE DISP button on the radio for at least five seconds until SETTINGS is displayed. 3. Press the SEEK PTYPE up or down arrow to scroll through the main menu. 4. Scroll until TIRE MON appears on the display. 5. Press the 1 PREV or 2 NEXT button to enter the submenu. RESET will be displayed. 6. Press the TUNE DISP button to reset. A chime will be heard to verify the new setting and DONE will be displayed for one second. 7. Once the monitor has been reset, scroll until EXIT appears on the display. 8. Press the DISP button to exit programming. A chime will be heard to verify exit. The system completes the calibration process during driving. The system normally takes 15 to 20 minutes of driving in each of three speed ranges to "learn" tire pressures. The speed ranges are 15 to 40 mph (25 to 65 km/h), 40 to 65 mph (65 to 105 km/h) and above 65 mph (105 km/h). When learning is complete, the system will alert you after two to eight minutes if a tire is 12 psi (83 kPa) different from the other three tires. Detection thresholds may be higher and detection times may be longer on rough roads, curves and at high speeds. The system is not capable of detection at speeds greater than 70 mph (110 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. 6-44
