Where is the Tire Pressure Monitoring in Passat?
2 Answers
Passat's tire pressure monitoring system data is displayed on the central dashboard screen. The tire pressure monitoring requires driving for a few minutes before it appears; you can also check the tire pressure by selecting the tire pressure monitoring interface via the steering wheel buttons when the vehicle is stationary. Tire pressure monitoring automatically and continuously monitors the tire pressure during vehicle operation, alerting drivers to leaks or low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. Wireless transmitters send pressure information from inside the tire to a central receiver module, which then displays the tire pressure data. 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 tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of tires to monitor pressure. Introduction to 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 direct systems, 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 like a direct system.
The tire pressure monitoring information for the Volkswagen Passat is usually displayed on the instrument panel and can be accessed using the multifunction buttons on the steering wheel. The specific steps are: After starting the vehicle, press the arrow button on the right side of the steering wheel to switch to the trip computer menu, then find the 'Settings' or 'Vehicle Status' option. Scroll down to view the tire pressure values for all four tires. If there is any abnormality in the tire pressure, a warning icon will appear directly on the instrument panel. In such cases, it's best to stop and check for punctures or leaks. For newer models, this information can also be checked on the central control screen by tapping the 'Vehicle' icon and then navigating to the 'Tire Pressure' page. Remember to long-press the SET button to reset the system after adjusting the tire pressure; otherwise, false fault warnings may occur. It’s good practice to check tire pressure before long trips, as incorrect pressure can significantly damage the tires.
