Tire Pressure Monitoring System, Calibrating

WARNING: This page is about a different car, the 2023 Volkswagen Atlas. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The tire pressure monitoring system should always be calibrated only "after" the tire pressure values have been adjusted to the correct values.

If no pressure loss and no tire damage can be found after a tire pressure warning, the erroneous warning can be eliminated by calibrating.

Using the ABS speed sensors, the tire pressure monitoring system compares the RPM, the tire tread circumference and the vibration behavior of the individual wheels. The tire pressure monitoring system displays tire pressure changes in one or more wheels in the instrument cluster and in the Infotainment 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.

The Tire Pressure Monitoring Display Indicator Lamp -- has a yellow indicator lamp inside the instrument cluster.
