Methods to reset the maintenance light on an older Buick GL8: 1. Turn on the ignition switch, fully depress the accelerator pedal three times within 5 seconds to complete the reset; 2. If the maintenance light was already on before servicing the vehicle, it indicates a successful reset, and the light will turn off shortly after; 3. If the maintenance light was not on before servicing the vehicle, the success of the reset needs to be verified by checking the diagnostic tool data. The Buick GL8 is an MPV model under the Buick brand. In terms of body dimensions, it measures 5256mm in length, 1878mm in width, and 1776mm in height, with a wheelbase of 3088mm.
I've been driving an old Buick GL8 for several years and have reset the maintenance light multiple times. Insert the key and turn it to the ON position without starting the engine—that's when all the dashboard lights come on. Then locate the small button on the dashboard, usually labeled 'Trip Reset' or the mileage reset button. Press and hold it for about ten seconds, and the maintenance light will flash a few times before turning off. This light serves as a reminder to change the oil or perform scheduled maintenance. Resetting it after maintenance ensures it will prompt you on time next time. The old GL8 is quite sturdy, but its electronic system is a bit simpler, so avoid touching other switches to prevent accidental operations. Always pay attention to the dashboard status while driving—once the light is off, you're good. Keeping up with maintenance intervals will make the car more durable.
Resetting the maintenance light on the old GL8 is actually quite simple. First, turn the key to position II without starting the engine, then observe the dashboard. Some models have a RESET button—just press and hold it for about ten seconds until the light turns off or flashes. The maintenance light is designed to remind you when the vehicle needs servicing, and resetting it starts a new countdown to prevent maintenance delays. I've helped friends with this several times. The button location might vary slightly across different GL8 model years, but the method remains similar. If the light doesn’t go off, check the fuse or refer to the manual. A successful reset gives peace of mind, and regular maintenance ensures the car lasts longer and runs smoother.
