If you have fitted M+S tyres:
X
Check the tyre pressures (Y page 353).
X Restart the tyre pressure loss warning sys-
tem (Y page 355).
After fitting a spare wheel or an emergency
spare wheel, do not drive faster than
80 km/h. 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:
R never fit snow chains on the front wheels
R fit snow chains to the rear wheels in pairs.
! 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 357).
R only use snow chains when the road sur-
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.
R local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to fit snow chains. R
Do not exceed the maximum permissible
speed of 50 km/h.
R Snow chains must not be fitted to the emer-
gency spare wheel, e.g. a collapsible emer-
gency spare wheel.
i You can deactivate ESP ®
(Y page 67)
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 (cutting action). Tyre pressure
Tyre pressure specifications
G
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.
You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Operation with an emergency spare
wheel: the applicable value is stated on the
wheel and in the "Wheel/tyre combinations"
section (Y page 357). Tyre pressure
