Then press and hold the trip/reset button until a chime sounds five times, and "RESET" is displayed in the message center. When the system is reset, the odometer will again be displayed in the message center.
Turn the key to "LOCK". If the "CHG OIL" message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.
