How to Turn Off the Maintenance Light on a Buick?
2 Answers
The method to turn off the maintenance light on a Buick: Press the menu control button on the right side of the steering wheel, and you will see the maintenance reminder on the vehicle's dashboard. Then, press and hold the close button on the left side of the steering wheel until you hear a beep sound before releasing it. This will reset and cancel the maintenance light. The maintenance reminder light is a warning light set by the manufacturer during vehicle production to ensure proper vehicle operation, reminding the owner to take the car to a 4S shop for maintenance in a timely manner to ensure driving safety. The purpose of car maintenance is to keep the vehicle clean and in good technical condition, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. When the maintenance light comes on, the car should be taken for maintenance as soon as possible.
Last time I did maintenance on my Regal myself, I also encountered this issue. Actually, you can manually reset it in the center console screen. First, don't start the car, just turn the key to the ON position (dashboard lights up fully), then quickly press the accelerator pedal to the floor three times in a row, followed by pressing the hazard light button four times quickly. Finally, follow the blinking prompt on the dashboard and press the confirm button. However, note that for models after the 2018 version, it's better to use the steering wheel buttons: after powering on, long-press the right menu button to enter engineering mode, then select the maintenance reset option. For the old Excelle, you can reset it with just the key—specific steps are in Chapter 7 of the manual. After this operation, even if the light goes out, it's not fully done; you need to wait until the next oil change for the count to truly reset.
