R
Only use snow chains when driving on an
area completely covered by snow. Do not
exceed the maximum permissible speed of
30 mph (50 km/h). Remove the snow
chains as soon as possible when you are no
longer driving on snow-covered roads.
R
Local regulations may restrict the use of
snow chains. Applicable regulations must
be observed if you wish to mount snow
chains.
R
Snow chains must not be mounted on
emergency spare wheels.
If you intend to mount snow chains, please
bear the following points in mind:
R
you may not attach snow chains to all
wheel-tire combinations; see the "Tires and
wheels" section in the "Technical data"
chapter.
R
mount snow chains only in pairs and only
on the rear wheels. Observe the
manufacturer's installation instructions.
!
If snow chains are mounted on the front
wheels, the snow chains could grind
against the bodywork or components of the
chassis. This could result in damage to the
vehicle or the tires.
!
Vehicles with steel wheels
If you wish to mount snow chains to steel
wheels, make sure that you remove the
respective wheels' hubcaps first. The
hubcaps may otherwise be damaged.

You may wish to deactivate
ESP
®
page 63) when pulling away with
snow chains installed. This way you can
allow the wheels to spin in a controlled
manner, achieving an increased driving
force (cutting action).
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and death.
To assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle's ABS will not prevent
this type of loss of control.
You should drive particularly carefully on
slippery road surfaces. Avoid sudden
acceleration, steering and braking
maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X
Vehicles with manual transmission: engage
neutral.
X
Vehicles with automatic transmission: shift
the transmission to position
