If the message does not disappear after a re-
peat calibration, have the system checked as
soon as possible.
Tire pressure monitor
Principle
The system monitors tire pressure in the four
mounted tires. The system warns you if there
is a significant loss of pressure in one or more
tires.
General information
Sensors in the tire valves measure the tire in-
flation pressure and, depending on the model,
the tire temperature.
Further information and instructions on using
the system can also be found under Tire infla-
tion pressure, refer to page 236.
Functional requirements
The following prerequisites must be met for
the system; otherwise, reliable message of a
tire pressure loss is not assured:
▷ After a tire or wheel change, a reset was
performed with the correct tire inflation
pressure.
▷ After the tire inflation pressure was ad-
justed to a new value, a reset was per-
formed.
▷ Wheels with wheel electronics.
