Resetting Procedure

  1. Turn the ignition to RUN with the engine OFF.
  2. Press and release the reset stem in the lower center of the instrument panel (I/P) cluster until the OIL LIFE message is displayed.
  3. Once the alternating OIL LIFE and RESET messages appears in the display, press and hold the reset stem until several beeps sound. This confirms the OIL LIFE system has been reset.
  4. Turn the key to lock.

    If the CHANGE OIL message comes back on when you start the engine, the ENGINE OIL LIFE system has not reset. Repeat the procedure.
