GM Oil Life System - Resetting
WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change the oil prior to a change engine oil light or CHANGE OIL SOON message being turned on, reset the system.
After changing the engine oil, reset the system:
- Vehicles with Driver Information Center (DIC)
- Press the option button on the DIC until ENGINE OIL MONITOR appears on the DIC screen.
- Press the set/reset button to reset the system. The next screen indicates that the CHANGE OIL SOON message has been reset.
- Turn the key to LOCK/OFF.
If the vehicle has the uplevel DIC, when the gages button is pressed and the OIL LIFE REMAINING mode appears, it should read 100 percent OIL LIFE REMAINING.
- Vehicles without Driver Information Center (DIC)
- With the engine off, turn the ignition key to ON/RUN.
- Fully press and release the accelerator pedal slowly three times within five seconds.
- Turn the key to LOCK/OFF, then start the vehicle.
If the light or message comes back on when you start your vehicle, the oil life system has not reset. Repeat the procedure.
