How to Check Tire Pressure on XC60?
2 Answers
To check the tire pressure on an XC60, press the "MYCAR" button to enter the vehicle settings menu, then select "Tire Pressure" to view the readings. Introduction to Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, with alerts for tire leaks or low pressure to ensure driving safety. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure for each tire. The system automatically alerts when tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When a tire's pressure decreases, the vehicle's weight causes that tire's rolling radius to reduce, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire alert systems essentially rely on calculating tire rolling radius to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of both direct and indirect systems. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and overcomes 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 as effectively as a full direct system.
I've been driving my XC60 for over three years and always check the tire pressure before long trips. Press the arrow button on the left side of the steering wheel to switch the dashboard display to the vehicle information page. Use the directional keys to scroll down to the tire pressure monitoring icon, usually visible on the second page. The values for all four wheels are clearly displayed on the screen, turning yellow with an alarm if below 2.2Bar. A quick reminder: measuring when the car is cold gives the most accurate reading; if you've just driven on the highway, wait half an hour before checking. With the current hot weather, tire pressure tends to be higher—just yesterday I noticed my front tires were up to 2.6, so I let some air out. It's advisable to check monthly, especially before mountain drives, as incorrect tire pressure not only wastes fuel but also poses risks.
