The LOW TIRE PRESSURE message will also be displayed while the ignition is on until you reset (calibrate) the system. Don't reset the tire pressure monitor 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 system will not work properly and may not alert you when a tire is low. Any time you adjust a tire's pressure, rotate your tires, or have one or more tires repaired or replaced, you'll need to reset (calibrate) the tire pressure monitor system. You'll also need to reset the system whenever you buy new tires and whenever the vehicle's battery has been disconnected. To reset (calibrate) the system: The tire pressure 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 SCAN 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 TUNE 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 4 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). 5-74
