Snow chains
! You must drive at raised vehicle level
(level 1) if snow chains have been mounted.
The vehicle may otherwise be damaged.
!
On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and
tire combinations" section under "Tires and
wheels".
! 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.
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
that have been specially approved for your
vehicle by Mercedes-Benz, or are of a
corresponding standard of quality.
If you intend to mount snow chains, please
bear the following points in mind:
R
Snow chains cannot be mounted on all
wheel-tire combinations; see the
information under "Wheel and tire
combinations" in the "Wheels and tires"
section.
R
Mount snow chains only in pairs and only
on the rear wheels. Observe the
manufacturer's mounting instructions.
R
Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as
possible when you come to a road that is
not snow-covered.
R
Local regulations may restrict the use of
snow chains. Observe the relevant
regulations when mounting snow chains.
R
Do not exceed the maximum permissible
speed of 30 mph ( 50 km/h).
R
On vehicles with Active Body Control (ABC),
you must drive at a raised vehicle level if
snow chains have been mounted
(
Y
page 179).
i
You may wish to deactivate ESP
®
when
pulling away with snow chains mounted
(
Y
page 59). This way you can allow the
wheels to spin in a controlled manner,
achieving an increased driving force
(cutting action).

Important safety notes
G
WARNING
Tires with tire pressures that are too low or
too high are associated with the following
hazards:
R
they can burst, in particular if the vehicle is
heavily laden or when driven at high
speeds.
R
the tires can wear excessively and/or
unevenly, which can severely impair tire
traction.
R
the driving, steering and braking
characteristics may be severely impaired.
There is a risk of accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires
including the spare wheel:
R
monthly, at least
R
if the load changes
R
before beginning a long journey
R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
