Tyre pressure monitoring system
Function of the tyre pressure monitoring sys‐
tem
The system checks the tyre pressure and the
tyre temperature of the tyres fitted to the vehicle
by means of a tyre pressure sensor.
The tyre pressure and the tyre temperature
appear in the on-board computer (
If there is a substantial pressure loss or if the
tyre temperature is excessive, you will be
warned in the following ways:
via display messages ( page 404).

via the h warning lamp in the instrument
R
cluster ( page 427)
/
The tyre pressure monitoring system is only an
aid. It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pressure
suitable for the operating situation.
In most cases, the tyre pressure monitoring sys‐
tem will automatically update the new reference
values after you have changed the tyre pressure.
You can, however, also update the reference val‐
ues by restarting the tyre pressure monitoring
system manually (
