Oil Change Reminder Lamp: Testing and Inspection

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 600 miles (1 000 km). 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 3,000 miles (5 000 km) 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 driver information center (DIC).

2. Press and hold the SET/RESET button on the DIC for more than five seconds. The oil life will change to 100 percent.

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.
