3 Answers
The method to reset the maintenance light on the Buick GL6 is: 1. Turn on the ignition switch with the engine off; 2. Use the MENU button and the scroll adjustment wheel to display the oil life interface on the instrument panel; 3. Press and hold the SET/CLR button for a few seconds to reset the oil life to 100%; 4. Turn off the ignition switch to complete the reset. The Buick GL6 has a length, width, and height of 4692mm, 1794mm, and 1626mm respectively, with a wheelbase of 2796mm. In terms of power, the Buick GL6 is equipped with a 1.3L turbocharged engine, with a maximum power of 120kW and a maximum torque of 230Nm.
I've seen many Buick GL6 owners unsure what to do when the maintenance light comes on, but the reset process is actually quite simple and mainly involves buttons on the instrument panel. Here are the general steps: First, park the car in a safe place and turn off the engine, making sure the key is removed. Then, press and hold the Trip button on the left side of the steering wheel. With your other hand, turn the key to the ON position without starting the engine. At this point, the instrument panel screen will display flashing maintenance information. Continue holding the Trip button for about 10 seconds until the numbers reset to zero or the prompt disappears. Then release the button, turn off the key, wait a few seconds, and restart the car—that should do it. This method works for most GL6 models, but if your car is a higher trim with a multifunction steering wheel, you might need to use the Mode button instead of Trip. Be patient during the process and avoid rushing; it's better to complete it in one go to prevent accidentally triggering other systems. I recommend owners practice this after each maintenance to avoid confusion next time, as frequent trips to the dealership are time-consuming and costly. Also, if the light still doesn't turn off, there might be a minor issue with the sensor or computer, so check the vehicle's maintenance records. Safety first—never attempt this on the road; find an empty parking lot instead.
As a GL6 owner, I actually figured out how to reset the maintenance light myself last year, and it turned out to be quite straightforward. The key is locating those small buttons: first turn off the engine and sit in the driver's seat, remove the key completely and wait for half a minute. Then, with your left hand, press and hold the reset button near the instrument cluster (for GL6, it's usually the Trip button below the left side of the steering wheel), while simultaneously turning the key to the ACC position with your right hand (don't start the engine). When the instrument panel lights up, watch for the maintenance reminder to start flashing. Hold for about ten seconds before releasing the button, and it will reset automatically. I was a bit nervous the first time, but after a few practices, it became second nature—saving me trips to the repair shop. If you make a mistake, like holding the button too long, the light might not change; usually, restarting the vehicle and trying again works. I recommend downloading the official app or checking the owner's manual as backup steps, since details may vary across different GL6 model years. Actually, the maintenance light reminds you it's time for an oil change—after resetting, don't forget to service the car as scheduled, or it could harm the engine. This trick helps save money, and learning it makes daily car maintenance much easier!
