Turn off the ignition switch, shut down the engine, and press and hold the right button on the instrument panel with your left hand. While holding the right button, turn on the ignition switch, and continue to hold the right button until the maintenance light enters the reset mode, then release the right button. Within 20 seconds of releasing the right button, press the left menu button once to confirm the reset.
Resetting the maintenance light on the Great Wall Wingle 7 diesel version is actually quite simple. I often use this trick when driving: turn the car key to the ACC position (the position where the power is on but the engine is not started), then find the ODO button on the dashboard, hold it down, and observe the maintenance mileage number on the screen. It will count down from the current value to 0 km. At this point, release the button to complete the reset. After resetting, the maintenance reminder light will turn off, making the display much cleaner. Remember to perform this operation after maintenance, otherwise the system will misjudge the next maintenance time. I usually perform maintenance every 5,000 km. For diesel vehicles, it's important to change the oil filter frequently to keep the engine clean, which can extend its service life and save fuel. Don't find it troublesome; developing good habits will give you peace of mind.
