HOW TO RESET THE OIL LIFE SYSTEM
The GM Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to the "CHG OIL" message being turned on, reset the system.

After changing the engine oil, reset the system by doing the following:
1. Press and release the trip/reset button until the "OIL LIFE" message is displayed.
2. 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.
3. Turn the key to "LOCK".
4. If the "CHG OIL" message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.

Your vehicle has a unique oil filter element. When installing the filler cap do not exceed 18 lb. ft. (25 Nm). Inspect the condition of the O-ring and replace if damaged.
