Tire Monitoring System: Service Precautions

General information
Please observe the instructions in Owners Manual.

For safety reasons, damaged wheel electronics or valves must be replaced.

Do not use steam cleaners or a powerful jet of compressed air for cleaning wheel electronics.

The wheel electronics must be replaced if tire sealant has been applied, as liquid deposits on the pressure sensor could lead to incorrect displays.

The tire pressure monitoring system monitors the inflation pressure of the tires on the four road wheels while the vehicle is moving.

If wheels are changed around to different positions on the vehicle, if different wheels are installed, or if the wheel pressure sensors are replaced, the new status of the system must be confirmed via the steering column switch or the operating unit in the center console. If replaced, the wheel sensors must be re-adapted accordingly to match the system.

Note:
^ After changing the wheels (including wheel electronics), for instance from summer to winter tires, the tire pressures must be checked and the wheel electronics re-adapted to the control module.

A malfunction may be detected and registered in the DTC memory:

If fewer than three wheels are installed with wheel electronics.

If winter tires without wheel electronics are installed. (in this case the yellow warning lamp will light up in the instrument cluster; this cannot be deactivated via the system.)
