How to Reset the Maintenance Light on a Buick?

[StAllie]

Steps to reset the maintenance light on a Buick: 1. Turn on the ignition; 2. Press the menu button on the control stalk; 3. Use the adjustment wheel to switch and select the vehicle information menu; 4. Rotate the adjustment wheel to select oil life; 5. Press and hold the confirmation button for several seconds; 6. The dashboard display will show 100% oil life, indicating a successful reset. The purpose of the maintenance light is to record the mileage of some important components, serving as a reminder for the car owner and maintenance personnel. Although the maintenance light does not affect the car's performance, it must be reset after maintenance; otherwise, the owner cannot accurately know the usage time of new components when replacing them next time.
