BYD Song Pro's tire pressure monitoring is located under the mode button on the right side of the steering wheel. Press the display toggle button once, then use the volume key to scroll down to switch content. Scrolling three times will bring you to the tire pressure display. Tire pressure monitoring is a system that automatically monitors tire pressure in real-time while driving, alerting the driver to tire leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct TPMS: Direct TPMS uses 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. The system automatically alerts when tire pressure is too low or there's a leak. Indirect TPMS: When a tire's pressure decreases, the vehicle's weight causes that tire's rolling radius to become smaller, making it rotate faster than other wheels. By comparing the rotational speed differences between tires, it monitors tire pressure. Indirect TPMS actually relies on calculating tire rolling radius to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems above, equipping direct sensors in two diagonally opposite tires while also having a 4-wheel indirect system. Compared to using only direct systems, this hybrid system can reduce costs and overcome the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a direct system.
