Tire pressure control system, servicing
Observe operating information in operating instructions.
If the micro-encapsulated bolt of the wheel electronics was loosened, the bolt must always be replaced.

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

Do not clean wheel electronics using pressure washers or strong pressurized air stream

After using tire sealing liquid, the wheel electronics must be replaced, since a possibility of an incorrect measurement exists due to deposits of the liquid at pressure sensor.
