Operation
Winter driving
Have your vehicle “winter proofed” at a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, at the on-
set of winter. This service includes the fol-
lowing:
앫
engine oil change, if the current oil has
not been approved for winter use
앫
the antifreeze/anti-corrosion concen-
tration will be checked
앫
washer fluid concentrate will be added
to the windscreen and headlamp clean-
ing system* fluid
앫
the battery will be checked
앫
a tyre change
Use winter tyres at temperatures below
+7 °C and on snow or ice-covered roads.
Only then can the maximum effect of ABS
and ESP ® be ensured in winter too.
Use winter tyres of the same make and
tread on all wheels to maintain safe han-
dling characteristics.
Always observe the maximum permitted
speed specified for the winter tyres you
have fitted. If you fit winter tyres which
have a lower maximum permitted speed
than that of the vehicle, affix an appropri-
ate warning sign showing the maximum
permitted speed in the driver’s field of vi-
sion. This can be obtained at a qualified
specialist workshop, e.g. at a
Mercedes-Benz Service Centre.
In such circumstances, you should also re-
strict the maximum speed of the vehicle to
the maximum permitted speed for the win-
ter tyres using permanent Speedtronic

For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains
which have been specially approved for
Mercedes-Benz vehicles.
!
For AMG tyres, the notes concerning the
use of AMG snow-chain-compatible winter tyres
must be observed. The use of snow chains is only
permissible with these tyres.

You must replace winter tyres with a tread
depth of less than 4 mm immediately. They
are no longer suitable for use in winter.

Risk of accident
If you fit the spare wheel* when driving with
winter tyres, please be aware that driving
stability will be impaired owing to unstable
cornering characteristics caused by the dif-
ferent tyres. You should therefore adapt
your driving style and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
