Tire chains cannot be mounted.
Snow tires should be used instead.
The system monitors the tyre infla-
tion pressure in the four fitted tyres.
The system warns if the tyre infla-
tion pressure in one or more tyres
has fallen.
Sensors in the tyre valves measure
the tyre inflation pressure and tyre
temperature.
The system detects the fitted tyres
automatically. The system shows
the preset specified pressures on
the Control Display and compares
them to the current tyre inflation
pressures.
If tyres are fitted which are not
listed on the tyre inflation pressure
labels in the vehicle, see page 278, for example tyres with special
approval, the system must be
actively reset. The current tyre
inflation pressures are then
accepted as the specified values.
To operate the system, also please
comply with the other information
and notes in the chapter Tyre infla-
tion pressure, see page 278.
The following requirements must be
met for the system, otherwise relia-
ble signalling of a loss of tyre infla-
tion pressure is not ensured:
• After each tyre or wheel change,
the system has detected the fit-
ted tyres, updated the relevant
information and, after a short
journey, shown it on the Control
Display.

NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may
damage the vehicle body and sus-
pension, and adversely affect driving
performance.

WARNING
The display showing the specified
tyre inflation pressures does not
replace the tyre inflation pressure
information on the vehicle. If incorrect
data has been entered into the tyre
settings, the specified tyre inflation
pressures will also be incorrect. As a
result, reliable signalling of a loss of
tyre inflation pressure can no longer
be guaranteed. There is a danger of
injury and damage to property. Make
sure that the tyre sizes of the fitted
tyres are displayed correctly and that
they match the specifications on the
tyres and the tyre inflation pressure
information.
