Oil Change Reminder Lamp: Service and Repair
GM Oil Life System Resetting
The vehicle has a computer system that has a change engine oil message, indicating when to change the engine oil and filter. This is based on engine
revolutions and engine temperature, and not on mileage. Based on driving conditions, the kilometers or mileage at which an oil change will be indicated
can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed.
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. The change engine oil message will
come on. The oil must be changed as soon as possible. It is possible that, if the vehicle is driven 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, the oil must be changed at 3,000 miles (5 000 km) since the last oil change. Remember to reset the
oil life system whenever the oil and filter is changed.
Resetting Procedure
1. Turn the ignition to RUN with the engine OFF.
2. Press and release the reset stem in the lower center of the instrument panel (I/P) cluster until the OIL LIFE message is displayed.
3. Once the alternating OIL LIFE and RESET messages appears in the display, press and hold the reset stem until several beeps sound. This confirms
the OIL LIFE system has been reset.
4. Turn the key to lock.
If the CHANGE OIL message comes back on when you start the engine, the ENGINE OIL LIFE system has not reset. Repeat the procedure.
Alternate Method
1. Turn the ignition key to RUN with the engine off.
2. Fully press the release the accelerator pedal 3 times within 5 seconds. Several beeps sound. This confirms the oil life system has been reset.
3. If the CHANGE/OIL message comes back on when you start the engine, the engine oil life system has not been reset. Repeat the procedure.
