How to Turn on the Tire Pressure Monitoring?
2 Answers
Tire pressure monitoring is automatically activated and requires no additional operation. The tire pressure monitoring system automatically and continuously monitors the tire pressure while the vehicle is in motion, and alerts the driver in case of tire leakage or low pressure to ensure driving safety. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts the driver if the tire pressure is too low or if 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 differences in rotational speed between the tires, the system monitors the tire pressure. The indirect tire pressure alert system essentially relies on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS): This system combines the advantages of both the direct and indirect systems. It is equipped with direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to using only a direct system, this hybrid system reduces costs and overcomes the limitation of the indirect system, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as effectively as a direct system.
I think many cars nowadays come with a tire pressure monitoring system, and turning it on is actually quite simple. Having driven for ten years, I've found that the operation methods are pretty similar across different models. Usually, there's a settings button on the steering wheel. Press it, then use the left/right buttons or scroll wheel to navigate to the 'Tire Pressure' or 'TPMS' option in the dashboard menu, and click to enter for real-time pressure readings. Some cars require you to drive a bit before the system activates and displays the data, while others come with an app for remote monitoring, which is quite convenient. I recommend resetting it every season—after inflating the tires, press and hold a certain button for a few seconds until the indicator light changes, signaling success. Developing a habit of regularly checking tire pressure can not only help avoid the risk of a blowout but also extend tire lifespan, which is especially important for long-distance driving. Last time, I avoided an accident by detecting a leak early.
