Tire Pressure Monitor
TPM
The concept
Measuring the inflation pressure in the four
mounted tires. The system notifies you if there is
a significant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Reset the system again after each correction of
the tire inflation pressure and after every tire or
wheel change.
System limitations
Sudden, serious tire damage caused by
external influences cannot be indicated in
advance.<
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pressures.
The system is inactive and cannot indicate a flat
tire:
> If a wheel without TPM electronics, e.g. a
compact spare wheel, is mounted.
> Interference with TPM by other systems or
devices with the same transmission fre-
quency.
Resetting the system
Reset the system again after each correction of
the tire inflation pressure and after every tire or
wheel change.
