To reset the tire pressure warning light on the 2020 Great Wall Poer, perform a tire pressure reset. The method for tire pressure reset is as follows: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button. After hearing a "beep" sound, release the button. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver to low pressure or leaks to ensure driving safety. There are generally three reasons for abnormal tire pressure warnings: Abnormal tire pressure: The system usually triggers a warning when the pressure is below 1.8 bar or above 3.0 bar. In this case, check and adjust the tire pressure. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the system will still record the old data, causing the tire pressure warning light to remain on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light may illuminate. In case of sensor damage, the only solution is to replace it with a new one.
Two years ago, the tire pressure warning light on my Great Wall Pao kept coming on, which initially gave me a scare. This usually indicates low tire pressure or a sensor false alarm. The standard tire pressure is generally around 2.4 bar, as indicated on the label on the door B-pillar. Use a pressure gauge to measure all tires, inflate them to the specified value, and then test drive for a few minutes to see if the light goes off. If the pressure is normal but the light remains on, you need to manually reset it: start the car without igniting the engine, use the buttons on the right side of the steering wheel to select the instrument menu, find the tire pressure monitoring reset in the vehicle settings, and confirm the reset. Drive for a while, and the system will self-calibrate. Don’t forget to check the tire pressure monthly—it saves fuel and prevents blowout risks. For older vehicles, the sensors may age and need replacement, which is quite common. Safety first—don’t delay addressing a warning light for too long.
