Oil Change Reminder Lamp: Service and Repair
GM Oil Life System Resetting
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL SOON
message will come On. Change the engine oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best
conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least
once a year and at this time the system must be reset.
If the system is ever reset accidentally, change the engine oil at 5 000 km (3,000 mi) since last oil change.
How to Reset the Engine Oil Life System
To reset the Engine Oil Life System, do the following:
1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC, or the trip odometer reset stem if the vehicle does not have DIC buttons, for more than five
seconds. The oil life will change to 100%.
If the CHANGE ENGINE OIL SOON message comes back on when you start the vehicle, the Engine Oil Life System has not reset. Repeat the
procedure.
