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.

To reset the Change Engine Oil light, do the following:

• 1. Turn the ignition key to RUN with the engine off.

• 2. Fully press and release the accelerator pedal slowly three times within five seconds.

• 3. If the Change Engine Oil light flashes for five seconds, the system is reset.

• 4. Turn the key to LOCK.

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. If it still does not reset, see your dealer for service.
