Engine Oil Replacement Reminder Reset - Procedure 37

    Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the engine oil life system:

  1. Place the vehicle in P (Park).
  2. From the infotainment home screen, select Vehicle Status > Maintenance > Oil Life > Reset.
  3. Follow the menu and select Reset on the display screen. Then select Reset to confirm the reset. The percentage will change to 100%.

    If the vehicle has a CHANGE ENGINE OIL SOON message and it comes back on when the vehicle is started and/or the OIL LIFE REMAINING is near 0%, the engine oil life system has not been reset. Repeat the procedure.
