Here is the proper way to reset the tire monitor.
Tire Inflation Monitor Resetting
In order to reset (calibrate) the system, turn the exterior lamp control from OFF to parking lamps 3 times within 5 seconds, while the ignition is ON. You may also reset the system through Vehicle Customization Settings using the following procedure:
Turn the ignition to ACC or ON and turn the radio off.
Press and hold the DISP button on the radio for at least five seconds until SETTINGS is displayed.
Press the SEEK up and down arrows to scroll through the main menu.
Scroll until TIRE MON appears on the display.
Press the PREV or NEXT button to enter the submenu. RESET will be displayed.
Press the DISP button to reset. A chime will be heard to verify the new setting and DONE will be displayed for one second.
Once the monitor has been reset, scroll until EXIT appears on the display.
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 15-20 minutes of driving in each of three speed ranges to learn tire pressures:
25-65 km/h (15-40 mph)
65-105 km/h (40- 65 mph)
above 105 km/h (65 mph)
