Tyre Pressure Monitor TPM
Principle
The system monitors the tyre pressure in the
four fitted tyres. The system warns if the infla‐
tion pressure in one or more tyres has fallen
considerably. To do this, the sensors in the
tyre valves measure the tyre pressure and tyre
temperatures.
Note
To operate the system, also follow the other
information and notes under tyre inflation pres‐
sure, see page 200.
Operating requirements
For the system, a reset must have been made
with the correct tyre inflation pressure, other‐
wise reliable signalling of a flat tyre cannot be
assured.
