How to Use the Car Tire Pressure Monitoring System?

Press and hold the setting button on the display for about 3 seconds until you hear a click, and the left front wheel will flash; at this time, bring the display close to the sensor, and the display will automatically receive the sensor's ID. After the display shows the identification, click OK to confirm; then press SET to proceed to other tires, approach the other sensors one by one, and debug them sequentially. Tire Pressure Monitoring: Tire pressure monitoring is the real-time automatic monitoring of tire pressure during car driving, and it alerts for tire leaks and low pressure to ensure driving safety. Direct Tire Pressure Monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It uses a wireless transmitter to send the pressure information from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system will automatically alert. Indirect Tire Pressure Monitoring: When the pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between the tires, the system monitors the tire pressure. The indirect tire pressure alert system actually relies on calculating the rolling radius of the tires to monitor the pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above, equipping direct sensors in two diagonally opposite tires and a 4-wheel indirect system. Compared to using a full direct system, this composite system can reduce costs and overcome the defect of the indirect system not being able to detect when multiple tires have low pressure simultaneously. However, it still cannot provide real-time data of the actual pressure in all four tires like the direct system does.
I find the tire pressure monitoring system incredibly convenient in daily life. Every time I start the engine, I first check the dashboard: the yellow tire pressure warning light will briefly illuminate and then automatically turn off; if it stays on or suddenly lights up while driving, it means one of the tires has abnormal pressure. In such cases, I find a safe spot to pull over and use the onboard tire pressure gauge to check all four tires one by one. If the pressure is below the recommended value (usually indicated on a label on the door frame, e.g., 2.2-2.5 bar), I quickly inflate them using an air pump. Resetting the system is simple—just press the button on the steering wheel, navigate to the TPMS settings in the menu, and reset it. Regular manual checks are also crucial; doing it monthly helps prevent the risk of a blowout, especially before long trips, ensuring stable tire pressure gives me peace of mind. The tire pressure system isn’t just a tool—it helps me save on tire wear costs and adds a safety bonus to my driving.
