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 the 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 manufacturer of your vehicle 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
manufacturer 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.
Using
Snow chains may only be used in pairs on the
rear wheels with tyres of the following sizes:
▷
255/45 R17.
▷
225/50 R17.
▷
255/40 R18.
Observe the snow chain manufacturer's instruc‐
tions.
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, see
page
, for example tyres with special appro‐
val, the system must be actively reset. The cur‐
rent 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 inflation pressure, see page
