How to Reset the Change Engine Oil Message
The GM Oil Life System
t 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 message being turned on,
reset the system.
After changing the engine oil, the system must be reset.
To reset the CHANGE ENGINE OIL message use one
of the following procedures:
Using the Radio
1. Turn the ignition to ACC or ON, with the radio off.
2. Press and hold the TUNE DISP button on the radio for
at least five seconds until SETTINGS is displayed.
3. Press the SEEK PSCAN up or down arrow to scroll
through the main menu.
4. Scroll until OIL LIFE appears on the display.
5. Press the 1 PREV or 2 NEXT buttons to enter the
submenu. RESET will be displayed.
6. Press the TUNE DISP button to reset. A chime will
be heard to verify the new setting and DONE will be
displayed for one second.
7. Once the indicator has been reset, scroll until EXIT
appears on the display.
8. Press the TUNE DISP button to exit programming.
A chime will be heard to verify the exit.
Using the accelerator pedal
1. Turn the ignition to ON, with the engine off.
2. Fully press and release the accelerator pedal three
times within five seconds. If the CHANGE ENGINE
OIL message flashes, the system is reset. However, if
it stays on, it did not reset. You’ll need to repeat the
reset procedure.
