located on the inside of the wheel.
The list can also include wheel/tyre sizes that
are only suitable for certain models.
Information about approved wheels and tyres
for the vehicle can be requested from an au-
thorised Service Partner or another qualified
Service Partner or specialist workshop.
Observe the snow chain manufacturer's in-
structions.
If equipped with a Tyre Pressure Monitor: do
not reset the Tyre Pressure Monitor when us-
ing snow chains. Otherwise, incorrect values
may be displayed.
If equipped with a flat tyre monitor: do not ini-
tialise the flat tyre monitor when using snow
chains. Otherwise, incorrect values may be dis-
played.
When driving with snow chains, activate the
drive-off support to optimise propulsion, if nec-
essary.
Maximum speed with snow chains
When snow chains are fitted, do not exceed

Tyre Pressure Monitor
Principle
The Tyre Pressure Monitor monitors the tyre
pressure and issues a warning if the tyre pres-
sure has dropped.
General
Sensors in the tyre valves measure the tyre
inflation pressure and tyre air temperature.
Depending on the tyres detected or entered,
the system displays the specified nominal
pressures on the control display and compares
them to the current tyre inflation pressures.
If the vehicle is fitted with tyres which are not
listed in the tyre inflation pressure information
on the vehicle, for example tyres with special
approval, the system must be actively reset.
