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.

After changing the engine oil, reset the system by performing the following steps:

  1. Turn the ignition key to RUN with the engine OFF.
  2. Fully press and release the accelerator pedal three times within 5 seconds.

If the Change Engine Oil light is flashing, the system is 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, it did not reset. You will need to reset the system again.
