TPMS Reminder Reset - Procedure 17

NOTE: The manfacturer's description for this procedure is restarting the the tire pressure monitor.
NOTE: The tire pressure monitor must be restarted when tire pressures are set to a new value (as a result of changed drive or load characteristics, for example). The tire pressure monitor then monitors the new tire pressure values. Re-inflating tires to the currently established specification does not require a restart.
NOTE: TPMS restart is accomplished by using the multifunction display control buttons on left side of steering wheel.
  1. Turn ignition switch to OFF position.
  2. Ensure inflation pressure of all 4 tires is set to specification.
  3. Make sure that the SmartKey is in position 2 in the ignition lock.
  4. Press and hold the lower left button (Menu Scroll) on the multifunction steering wheel until the standard display (Odometer/Trip Odometer) appears in the multifunction display.
  5. Press the UP or DOWN arrow button until the tire pressure of each wheel appears or the "Tire Pressure Displayed Only After Driving For A Few Minutes" message is shown.
  6. Press the reset button on the instrument cluster. See Fig 1. The "Restart Tire Pres. Monitor?" message appears in the multifunction display.
  7. To confirm the restart, press the + button. The "Tire Pres. Monitor Restarted" message appears in the multifunction display.
  8. After driving for a few minutes, the system checks whether the current tire pressures are within the specified range. The new tire pressures are then accepted as reference values and monitored.
