GM Oil Life System - Resetting

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The GM Oil Life System calculates when to change the engine oil and filter, based on the vehicle use. Anytime the oil is changed, reset the system so the next required oil change can be calculated. If the oil is changed before the Change Engine Oil light turns ON, reset the system.

After changing the engine oil, perform the following steps:

Turn the ignition to RUN, with the engine OFF.
Fully press and release the accelerator pedal 3 times within 5 seconds.

If the Change Oil light flashes, the system has been reset. The light will flash for up to 30 seconds or until the ignition is turned OFF.

If the light comes on again and stays on for 30 seconds at the next ignition cycle, the system did not reset. Reset the system again.
