HOW TO RESET THE CHANGE ENGINE OIL LIGHT
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 a change engine oil light being turned on, reset the system.

Always reset the engine oil life system to 100% after every oil change. It will not reset itself. To reset the change engine oil light, do the following:
1. Press the fuel information button until "ENGINE OIL LIFE" appears on the Driver Information Center (DIC).
2. Press and hold the select button. The engine oil life percentage will change to "100".
3. Turn the key to "OFF".
4. If the change engine oil light comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.
