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). 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.
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. Tyre pressure

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 prevent hazardous situations:
R
Adapt your 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.
14 Not in conjunction with Sports package code 952.
15 MOExtended tyres (tyres featuring run-flat characteristics) only in combination with an activated tyre pres-
sure loss warning system.
16 Use of snow chains not permitted. Observe the notes in the "Snow chains" section.
17 Observe notes on "Large wheels" in the "Wheel/tyre combinations" section. 304
Emergency spare wheelWheels and tyres

R
Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialis tworkshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. Points to remember
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correc tthe pressure as nec-
essary (Y page 295). The value on the wheel
or as given in the "Technical data" section
(Y page 302) is valid.
i When you are driving with the emergency
spare wheel fitted, the tyre pressure loss
warning system cannot function reliably.
Only restart the tyre pressure loss warning
system when the defective wheel has been
replaced with a new wheel.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed
limitation specified on the emergency spare
wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel. Removing the emergency spare wheel
X
Open the boot.
X Loosen lashing straps ;on emergency
spare wheel bag :.
X Remove emergency spare wheel bag :
with the "Minispare" emergency spare
wheel.
