How to use the tire pressure monitoring system in Changan CS75?
1 Answers
The method to use the tire pressure monitoring system in Changan CS75 is: After driving for a period of time, press the steering wheel's trip computer information adjustment button to view the tire pressure monitoring. Tire Pressure Monitoring: Tire pressure monitoring is the real-time automatic monitoring of tire pressure during vehicle driving, with alarms for tire leaks and low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: 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 pressure information 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 there is a leak. Indirect Tire Pressure Monitoring: When the pressure of a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the speed differences between tires, the system monitors the tire pressure. The indirect tire pressure alert system actually relies on calculating the tire's rolling radius 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 a 4-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the indirect system's inability to detect multiple tires with low pressure simultaneously. However, it still cannot provide real-time data of the actual pressure in all four tires like the direct system.
