How to Cancel the Tire Pressure Warning?

The method to eliminate the tire pressure warning on the Sagitar: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button. After hearing a "ding" sound, release the button. The tire pressure monitoring system will 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 in case of tire leaks or low pressure to ensure driving safety. There are three commonly used types of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and an indirect system is used for all four wheels. Compared to using only a direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time pressure data for all four tires like a direct system.
When my tire pressure warning light came on, I immediately pulled over to check. First, I used the onboard tire pressure gauge to measure each tire's pressure. The standard value is indicated on the door sticker, which in my case is 2.2 kg per square centimeter. I found one tire was low and quickly inflated it. After fixing it, I located the RESET button near the steering wheel and held it down for three seconds to clear the warning. Why check? Sometimes it's due to a small stone puncturing the tire and causing a leak, or a false alarm from temperature changes. Ignoring it directly is dangerous—uneven tire pressure on highways can easily lead to a blowout. I check my tire pressure monthly as a preventive measure, which is the most hassle-free approach. This warning is the car's guardian—don't ignore it.
