Snow chains
G
WARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abrasion
to the vehicle body or to chassis components.
This could cause damage to the vehicle or the
tires. There is a risk of an accident.
To avoid hazardous situations:
never mount snow chains on the rear
R
wheels
only mount snow chains in pairs on the
R
front wheels.
!
On some tire sizes there is not enough space
for snow chains. To avoid damage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" section under "Tires and wheels".
For safety reasons, Mercedes-Benz recom-
mends 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. For more information,
please contact a qualified specialist workshop.
If you intend to mount snow chains, please bear
the following points in mind:
Snow chains may not be mounted on all
R
wheel/tire combinations. Permissible wheel-
tire combinations (
Only use snow chains when driving on roads
R
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered.
Local regulations may restrict the use of snow
R
chains. Observe the appropriate regulations if
you wish to mount snow chains.
Do not exceed the maximum permissible
R
speed of 30 mph (50 km/h).
Never use Parking Pilot when snow chains are
R
installed ( page 173).

You may wish to deactivate ESP
away with snow chains installed . You can
thereby allow the wheels to spin in a controlled
manner, achieving an increased driving force
(cutting action).

WARNING
Underinflated or overinflated tires pose the
following risks:
the tires may burst, especially as the load
R
and vehicle speed increase.
the tires may wear excessively and/or
R
unevenly, which may greatly impair tire
traction.
the driving characteristics, as well as steer-
R
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
monthly, at least
R
if the load changes
R
before beginning a long journey
R
under different operating conditions, e.g.
R
off-road driving
If necessary, correct the tire pressure.
