When you have fitted M+S tyres:
X
Check the tyre pressures (Y page 365).
X Restart the tyre pressure loss warning sys-
tem (Y page 367).
X Restart the tyre pressure monitor
(Y page 369).
After fitting a spare wheel or an emergency
spare wheel, do not drive faster than
80 km/h. G
WARNING
The wheel/tyre dimensions and the tyre type
of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
To preven thazardous situations:
R Adap tyour driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimesions are dif-
ferent to those of the wheel being replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimesions are different
to those of the wheel being replaced.
R Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct. Snow chains
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 371).
R snow chains must not be fitted to the emer-
gency spare wheel, e.g. a “Minispare” or
collapsible emergency spare wheel.
R only fit snow chains in pairs and to the rear
wheels, even on vehicles with 4MATIC.
Observe the manufacturer' sinstallation
instructions.
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure tha tyou remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
On vehicles with AIRMATIC, you must drive at
raised vehicle level if snow chains have been
fitted (Y page 197).
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate
ESP ®
(Y page 72) 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). Tyre pressure

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. Tyre pressure
