Turn on the ignition switch to power the car, then turn the key to keep the engine in the off state, and set the ignition switch to "OFF" mode. Locate the control button. Press the "Reset" button once, and the display will show the reset system; press "Reset" again to switch to the next reset system. Select the maintenance reset system, then press and hold the indicator selection button for more than 5 seconds, and press the ignition button to start the vehicle. When the relevant icon appears, the maintenance light will be reset.
I've done the maintenance light manual reset several times, the steps are simple but require attention to detail. With the engine off, turn the key to the ON position (engine not started, only the dashboard lights up). Then press and hold the mileage reset button on the dashboard, that small protruding button usually labeled ODO or TRIP. Hold it firmly for about 10 seconds, don't release too quickly, and you'll see the maintenance light blink a few times before turning off, indicating a successful reset. After resetting, don't forget to note down the next maintenance time to avoid misleading you into thinking there's a problem with your car next time. The maintenance light is used to remind you of regular oil changes and vehicle condition checks; not resetting it will keep the annoying prompts coming. Doing it yourself saves time and money, but make sure the car is parked on level ground with the doors closed and don't get distracted by driving to press the button. If the reset fails, check if the button wasn't pressed firmly enough or if the battery voltage is too low, affecting the system.
