The method to reset the maintenance reminder light on Fengjun 7 is: 1. Turn off the ignition switch, and with the engine off, press and hold the right button (reset/zero) on the instrument panel with your left hand; 2. While continuing to hold the right button with your left hand, turn on the ignition switch, and keep holding the 'reset/zero' button until the maintenance light enters reset mode, then release the right button (reset/zero button); 3. Within 20 seconds of releasing the right button, press the left 'menu button' once to confirm the reset. The Fengjun 7 is a new-generation internet-connected pickup truck launched by Great Wall Motors, equipped with a GW4D20D 'China Core' engine paired with a 6-speed manual transmission.
Every time the maintenance reminder light comes on, I hold down the adjustment button on the right side of the dashboard with the engine off, then turn the key to the ignition position. At this point, the dashboard will beep twice. Wait until the maintenance icon flashes and disappears before releasing the button, and finally restart the vehicle. I tried twice before without holding it for more than 10 seconds, and the light didn't go off. Later, I found that you must hold it for 12 seconds for it to work. This method is particularly effective on the older diesel version of the Great Wall Wingle 7. For higher trim models with a central control screen, you can also find the maintenance reset option directly in the vehicle settings menu.
It's actually quite easy to reset the maintenance light yourself. First, turn off the car completely, then press and hold the small black round button at the lower right corner of the dashboard without releasing it. Next, turn the key to power on the dashboard lights, continue holding for about 15 seconds until you see the maintenance icon gradually dim like a candle going out, which means you've succeeded. Once, I forgot to reset it after maintenance, and after driving over a thousand kilometers, the system automatically activated engine protection mode limiting the RPM, so the reminder light really shouldn't be ignored. If the operation fails, it might be due to poor button contact or the mileage data not being reset during the last maintenance.
