Snow chains
Safety notes
WARNING
If snow chains are fitted to unsuitable tyres, the
snow chains can come into contact with vehicle
parts. There is a danger of accidents or dam‐
age to property. Only fit snow chains on tyres
that the manufacturer has approved as being
suitable for snow chains.
WARNING
Insufficiently tensioned snow chains can dam‐
age tyres and vehicle components. There is a
danger of accidents or damage to property. En‐
sure that snow chains are always adequately
tensioned. Re-tension them if necessary in ac‐
cordance with the snow chain manufacturer's
instructions.
Fine-link snow chains
The vehicle manufacturer recommends using
fine-link snow chains. Certain fine-link snow
chains have been tested, found safe for use in
traffic and categorised as suitable by the manu‐
facturer of the vehicle.
Information regarding suitable snow chains is
available from a Service Partner of the manufac‐
turer or another qualified Service Partner or a
specialist workshop.
Use
Snow chains may only be used in pairs on the
rear wheels with tyres of the following sizes:
▷ 205/60 R16.
▷ 225/50 R17.
▷ 225/45 R18.
Observe the snow chain manufacturer's instruc‐
tions.
Do not initialise the runflat indicator RPA with
snow chains fitted, as it may give incorrect read‐
ings.
Do not reset the Tyre Pressure Monitor TPM
with snow chains fitted, as it may give incorrect
readings.
When driving with snow chains fitted, activate
Dynamic Traction Control DTC briefly as re‐
quired in order to optimise traction.
Maximum speed with snow
chains
When snow chains are fitted, do not exceed
50 km/h, 30 mph.
Tyre Pressure Monitor
TPM
Principle
The system monitors the tyre inflation pressure
in the four fitted tyres. The system warns if the
tyre inflation pressure in one or more tyres has
fallen.
General
Sensors in the tyre valves measure the tyre infla‐
tion pressure and tyre temperature.
The system detects the fitted tyres automati‐
cally. 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, for exam‐
ple tyres with special approval, the system must
be actively reset. The current tyre inflation pres‐
sures are then accepted as the specified values.
When operating the system, please also comply
with the other information and notes in the Tyre
inflation pressure chapter, see page
336 .
