How to reset the tire pressure warning light on Haval H2s?

To reset the tire pressure warning light on the Great Wall Haval H2s, a computer and a Great Wall-specific tire pressure matching device are required for the reset procedure, which must be performed at a 4S dealership. When the tire pressure of the Haval H2s reaches ≥288 kPa, a high tire pressure warning will appear. In this case, it is necessary to reduce the tire pressure by deflating the tires to ensure normal tire pressure. The importance of tire pressure: Data shows that the proportion of accidents caused by tire blowouts in severe traffic accidents is very high, and among all factors that can lead to tire blowouts, insufficient tire pressure is the primary cause. This is not an exaggeration. Even if you do not choose a vehicle equipped with a tire pressure monitoring system, it is essential to pay attention to your vehicle's tires to avoid serious damage to both people and the vehicle. Hazards of excessive tire pressure: Excessive tire pressure reduces the contact area between the tire and the ground, significantly increasing the pressure and wear per unit area. This can easily lead to loss of braking control, tire blowouts when encountering road protrusions or depressions, damage to the vehicle's suspension system, and discomfort while riding. The normal tire pressure for the Haval H2s is 2.3-2.8 kg/cm². The manufacturer-recommended standard tire pressure is the most reliable, as it is based on extensive research and testing conducted during the vehicle's development and production. This tire pressure standard ensures the vehicle operates in optimal condition.
I also encountered the situation where the tire pressure warning light came on when I was driving a Haval H2s before. In this case, don't panic first. Find a reliable tire pressure gauge to check whether the air pressure of all four wheels and the spare tire meets the standard value (the tire pressure data is posted on the driver's door frame). If the tire pressure is normal, it's most likely a false alarm. You just need to press and hold the tire pressure reset button on the center console or near the steering wheel for a few seconds with the ignition on, and you'll succeed when you see the indicator light on the dashboard flash or go off. However, in my case, the light went off only after driving a few hundred meters after pressing the button, which is normal. If the light remains on after pressing, you should consider the possibility that the sensor battery is dead or the sensor is damaged. At this point, you'll need to go to a repair shop for professional equipment testing, as you can't fix it yourself.
