I've been driving the Great Wall Poer for almost three years and have thought about the maintenance light several times. For the 2021 Great Wall Poer, resetting the maintenance light isn't actually difficult—it mainly relies on the buttons on the instrument panel in combination with specific operations. The basic steps are: first, turn the ignition switch to the OFF position without shutting off the engine; then press and hold the TRIP button near the steering wheel without releasing it; next, turn the ignition switch to the ON position, where the instrument lights come on but the engine doesn't start; keep holding the TRIP button for about 10 seconds until the wrench icon flashes or disappears, indicating success. This clears the light, but don't rush the process, as it may fail otherwise. Additionally, this light usually reminds you to change the oil or perform a 5,000 km inspection. If you reset it without servicing the vehicle, minor issues may arise. It's best to reset it after maintenance or refer to the owner's manual to confirm the steps, as procedures may vary slightly across different model years. I've tried it multiple times with a high success rate, but if it doesn't work, just visit a 4S shop and let the technicians handle it—it's more hassle-free.
