Tire Pressure Monitoring System, Calibrating

NOTE:

Perform the calibration on the tire pressure monitoring system display only "after" the tire pressures have been adjusted to the correct values.

If no pressure loss and no tire damage is detected after a tire pressure warning, the erroneous warning can be eliminated by a calibration.

Using the ABS speed sensor, the tire pressure monitoring system compares the RPM, the tire tread circumference and the vibration behavior of the individual wheels. Changed in tire pressure on one or more wheels will show in the instrument cluster and in the infotainment system via the tire pressure monitoring system.

The tire tread circumference changes when:

The tire pressure is too low.
Tires have structural damage.
Vehicle is loaded on one side.
Wheels of one axle are loaded higher, for example, when towing trailer or driving uphill and downhill.
Snow chains are installed.
The emergency wheel is installed.
One wheel per axle was replaced.
