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!
