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 (1000 km). It is possible that, if driving under the best
conditions, the oil life 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 3000 miles (5000 km) since last oil change.
Resetting Procedure
Follow this procedure to reset the GM Oil Life System:
1. With the ignition key in RUN but the engine off, repeatedly push the trip/reset button until OIL is displayed on the driver information center
(DIC).
2. Once OIL is displayed, push and hold the trip/reset button for 5 seconds. The number will disappear and be replace by 100 indicating 100 percent
oil life remaining.
3. Turn the key to OFF.
4. If the change engine oil message comes back on, the engine oil life monitor has not reset. Repeat the procedure.
