How to reset the oil maintenance light on a Buick GL8?

After turning it on, press the MENU button on the control lever. Use the adjustment wheel to switch and select the vehicle information menu, then rotate the wheel to choose oil life. Press and hold the confirmation button for several seconds until the oil life shows 100%, indicating a successful reset and the maintenance light is cleared.
Resetting the oil maintenance light on the Buick GL8 is quite simple, and I often help friends with this issue. First, park in a safe spot and turn off the engine. Then, turn the key to the 'run' position—the one before starting the car—but don’t start it. Next, use the buttons on the left side of the steering wheel to navigate the dashboard: press the navigation button to find the settings menu icon, which might be a gear or tool symbol. Go into the submenu and look for 'Maintenance Settings' or 'Oil Life,' then select the option and hold the 'OK' button for about 5 seconds until the light turns off. If it doesn’t work, the steps might vary slightly depending on the model year—check the manual or ask a 4S shop for confirmation. This light only reminds you of the oil change interval; not resetting it won’t affect driving, but regular maintenance is key. I recommend doing this right after an oil change to keep the system accurate and avoid the annoying light.
