How to reset the tire pressure on a Great Wall H6?

Disconnect the negative terminal of the battery for more than one minute and then reconnect it; at this point, the trip odometer will reset to zero, and the tire pressure for all four tires will not display numerical values but only a horizontal line, with the yellow warning light on the left speedometer no longer flashing. Then drive approximately one kilometer, and the tire pressure values for all four wheels will be displayed and return to their previous normal state. Below is relevant information about the tire pressure monitoring system: 1. The tire pressure monitoring system automatically monitors and detects changes in tire pressure in real-time while the vehicle is in motion, alerting the driver to issues such as tire leaks, low pressure, or pressure increases due to rising environmental temperatures. 2. Classification of tire pressure monitoring systems: 1. Indirect tire pressure monitoring (WSB): When the pressure in any of the vehicle's tires decreases, the "rolling radius" of that tire naturally becomes smaller, causing its rotation speed to be slightly faster than the other wheels. The system identifies which tire has decreased pressure by comparing the "speed difference." It can monitor one or multiple tires simultaneously. 2. Direct tire pressure monitoring (PSB): Uses pressure sensors inside the tires to directly check and measure the pressure values, transmitting the relevant pressure data wirelessly to the control module. If abnormalities are detected, it will issue an audible warning or display relevant warning icons on the dashboard to alert the driver to check the tire pressure.
When I drive my Great Wall H6, the method to reset the tire pressure is quite simple. First, make sure the vehicle's ignition switch is turned to the ON position without starting the engine. Then, look for the button with the air tank symbol near the steering wheel and press it for a few seconds. Wait until the tire pressure warning light on the dashboard flashes a few times and then goes off, indicating that the reset was successful. The key is to actually drive the car for a short distance after the reset, with the speed exceeding 25 kilometers per hour, to allow the system to relearn the new tire pressure. Usually, if you change tires or inflate them and the tire pressure is abnormal, you must do this; otherwise, the warning light will keep flashing, affecting your driving. Additionally, I recommend regularly checking the tire pressure with a pressure gauge. In winter, you can adjust it slightly higher, and in summer, slightly lower, which can save fuel and make the tires more durable. Remember, before resetting, confirm that there are no dangerous situations like air leaks or punctures, or else it will be in vain, and you’ll still need to repair the car.
