Where is the tire pressure display for the 2020 Passat?
1 Answers
2020 Passat's tire pressure is displayed on the central screen of the instrument panel. The monitoring methods are as follows: Direct tire pressure monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, then displays the 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 in 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 rotational speed differences between tires, the system monitors the tire pressure. The indirect tire pressure warning system essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of both 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 reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
