How to check the tire pressure monitoring on Volvo XC40?
2 Answers
Volvo XC40 is equipped with a tire pressure monitoring system that functions as a tire pressure warning, not a display. When there is an issue with the tire pressure, the tire pressure warning light will illuminate on the dashboard, but the actual tire pressure values are not visible. More relevant information is as follows: 1. The indirect tire pressure monitoring system is also known as WSBTPMS. WSBTPMS uses the wheel speed sensors of the car's ABS anti-lock braking system to compare the rotational speed differences between tires to monitor tire pressure. ABS determines whether a wheel is locked via wheel speed sensors and decides whether to activate the anti-lock braking system. When tire pressure decreases, the vehicle's weight causes the tire diameter to reduce, resulting in changes in vehicle speed. These speed changes trigger the WSB warning system, alerting the driver to insufficient tire pressure. Therefore, indirect TPMS is a passive type of TPMS. 2. The tire pressure monitoring system, abbreviated as 'TPMS', stands for 'tire-pressure-monitoring-system'. This technology can automatically monitor various tire conditions in real-time by recording tire rotation speeds or via electronic sensors installed in the tires, providing effective safety protection for vehicle operation.
I've been driving a Volvo XC40 for several years, and checking the tire pressure monitoring is actually quite simple. After getting in the car and starting the ignition (no need to drive), just press the button on the left side of the steering wheel to switch to the central information screen on the dashboard. Look for the 'Vehicle Status' or 'Tire Pressure Monitoring' menu to see the tire pressure values for each wheel. If the tire pressure is abnormal, a yellow warning light will illuminate on the screen, indicating that a tire is underinflated. I usually check it monthly, especially during seasonal changes when temperature fluctuations can cause tire pressure to vary. In winter, it alarms if the pressure drops below 2.2 bar, and in summer, high pressure can also be problematic—keeping it around 2.3 bar is safest. By the way, the XC40's system is very smart; checking before highway drives can save fuel and prevent blowouts. If a warning appears, don’t rush on a long trip—visit a repair shop first to inflate or check for leaks. Regular maintenance of tire tread and pressure ensures the car lasts longer.
