Oil Change Reminder Lamp: Testing and Inspection

GM Oil Life System Resetting

The engine oil life system calculates engine oil life based on vehicle use and displays the CHANGE ENGINE OIL SOON message when it is time to change the engine oil and filter. The oil life system should be reset to 100% only following an oil change.

How to Reset the Engine Oil Life System

1. Using the DIC controls on the right side of the steering wheel, display REMAINING OIL LIFE on the DIC. When remaining oil life is low, the CHANGE ENGINE OIL SOON message will appear on the display.

2. Press SEL on the DIC controls and hold SEL down for a few seconds to clear the CHANGE ENGINE OIL SOON message and reset the oil life at 100%. Be careful not to reset the oil life display accidentally at any time other than after the oil is changed. It cannot be reset accurately until the next oil change.

The oil life system can also be reset as follows:

1. Turn the ignition on with the engine off.

2. Fully press and release the accelerator pedal three times within five seconds. If the CHANGE ENGINE OIL SOON message is not on, the system is reset.
