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 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, use the following steps:
1. Press the up and down arrow on the INFO button located to the right of the driver information center (DIC) menu.
2. Once XXX% ENGINE OIL LIFE menu is highlighted, press and hold the CLR button. The percentage will return to 100, and the oil life indicator
will be reset. Repeat the steps if the percentage does not return to 100.
3. Turn the key to OFF.
If the CHANGE ENGINE OIL message comes back on when you start the vehicle, the Engine Oil Life System has not reset. Repeat the procedure.
