Tire Monitoring System: Service and Repair

Tire Pressure Monitoring System Display, Performing Basic Setting

Applies only to tire pressure monitoring system display with PR number 7K6 / 7K9

Note:
Perform the basic setting 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 basic setting.

The tire pressure monitoring system display compares the speed and the rolling circumference on each wheel using the ABS sensors. The tire pressure monitoring system display shows when there is a difference in the rolling circumference on a wheel. The rolling 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.
- Spare wheel is installed.
- One wheel per axle was replaced.

The yellow tire pressure monitoring system display indicator lamp is inside the instrument cluster -arrow-.
