Snow chains
!
If snow chains are fitted to the rear
wheels, they may rub against the bodywork
or parts of the suspension. This may cause
damage to the vehicle or the tyres.
!
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:
R
snow chains cannot be fitted to all wheel-
tyre combinations. Permissible wheel-tyre
combinations (
Y
page 302).
R
snow chains must not be fitted to the emer-
gency spare wheel, e.g. a Minispare emer-
gency spare wheel.
R
fit snow chains only in pairs and only to the
front wheels. Observe the manufacturer's
installation instructions.
If snow chains are fitted, you cannot use
Active Parking Assist (
Y
page 166).
Do not exceed the maximum permissible
speed of 50 km/h.
i
You may wish to deactivate
ESP
®
(
Y
page 66) when pulling away with
snow chains fitted. This way you can allow
the wheels to spin in a controlled manner,
achieving an increased driving force (cut-
ting action).

WARNING
Tyres with too low or too high tyre pressure
contain the following hazards:
R
they can burst, in particular if the vehicle is
heavily laden or when driven at high
speeds.
R
the tyres can wear excessively and/or
unevenly, which can severely impair tyre
traction.
R
the driving, steering and braking character-
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:
R
at least every two weeks
R
if the load changes
R
before beginning a long journey
R
for changed operating conditions, e.g. off-
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.
