You can ask the 4S dealership to reset it using their computer system, or refer to the vehicle's manual. With the vehicle turned off, press and hold the trip meter reset button. Start the engine and keep holding the button until the maintenance indicator disappears before releasing it.

I just reset the maintenance light on my GL8 myself, it was pretty easy but you have to follow the steps. Turn off the ignition to shut down the car, then press and hold the INFO button on the steering wheel or dashboard (location may vary by model year) for about five seconds before starting the engine. The maintenance light will blink a few times and then turn off. Why reset it? It reminds you of the next service interval - you need to reset it after an oil change. If the light doesn't go off, maybe the button wasn't pressed firmly enough or there's a system fault, try repeating the process a few times. Regular maintenance light reminders help you remember to change filters and fluids. Safe to drive for months after, but recommended to reset after every service - developing this habit reduces potential issues.

My GL8 has been in use for several years, and every time the maintenance light comes on, I reset it myself to avoid unnecessary expenses at the 4S shop. After turning off the engine, locate the small button on the dashboard—usually the trip display or settings button—hold it down, then turn the ignition switch on. Wait a few seconds, and the light will go off. Remember, ensure the car is parked and stationary before operating to prevent accidents. After resetting, the onboard computer will recalculate the mileage and time, accurately reminding you of the next maintenance cycle. Also, if the light stays on constantly, it might indicate incomplete maintenance, such as incorrect oil change or a dirty filter, so double-check. Routine maintenance is that simple—don’t overlook it.

Resetting the GL8 maintenance light is a piece of cake for me. Usually, you can do it by holding down the dashboard button after turning off the engine. Simple steps: with the key in OFF position, press and hold the multifunction button for about five seconds, turn the key to ON without starting the engine, and the maintenance light going off indicates success. If there's no response, check for poor button contact or an onboard computer malfunction—it's best not to force it. By the way, the maintenance light is designed to help you keep track of mileage to avoid exceeding limits; resetting it reminds you of the next oil change, etc., thereby extending the engine's lifespan.
