Snow chains
G
WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is a risk of an accident.
To avoid hazardous situations:
never fit snow chains on the front wheels
R
fit snow chains to the rear wheels in pairs.
R
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure that you remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
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 that are of a corre-
sponding standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
snow chains cannot be fitted to all wheel-
R
tyre combinations. Permissible wheel-tyre
combinations ( page 350).
Y
only use snow chains when the road sur-
R
face is completely snow-covered. Remove
the snow chains as soon as possible when
you come to a road that is not snow-cov-
ered.
local regulations may restrict the use of
R
snow chains. Observe the appropriate reg-
ulations if you wish to fit snow chains.
do not exceed the maximum permissible
R
speed of 50 km/h.
i
You may wish to deactivate ESP
pulling away with snow chains fitted
( page 67). This way you can allow the
Y
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).
For more information on driving with an emer-
gency spare wheel, see (

Tyre pressure

Tyre pressure specifications
G WARNING
Tyres with too low or too high tyre pressure
contain the following hazards:
they can burst, in particular if the vehicle is
R
heavily laden or when driven at high
speeds.
the tyres can wear excessively and/or
R
unevenly, which can severely impair tyre
traction.
the driving, steering and braking character-
R
istics may be severely impaired.
There is a risk of accident.
Follow recommended tyre inflation pressures
and check the pressure of all the tyres includ-
ing the spare wheel:
at least every two weeks
R
if the load changes
R
before beginning a long journey
R
for changed operating conditions, e.g. off-
R
road driving
If necessary, correct the tyre pressure.
G WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and
malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is
a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle onto the tyre valve.
G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
