Snow chains
G
WARNING
If snow chains are fitted to the rear wheels,
they may scrape against the vehicle body or
chassis components. This could cause dam-
age to the vehicle or the tyres. There is a risk
of an accident.
To avoid hazardous situations:
R
never fit snow chains on the rear wheels
R
always fit snow chains in pairs to the front
wheels.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been specifically approved for your vehicle by
Mercedes-Benz, or that are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
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 combi-
nations (
Y
page 277).
R
only use snow chains if the road surface is
completely snow-covered. Remove the snow
chains as soon as possible when you come to
a road that is not snow-covered.
R
local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to fit snow chains.
R
do not exceed the maximum permissible
speed of 50 km/h.
R
when snow chains are fitted, never use Active
Parking Assist (
Y
page 158).
You may wish to deactivate ESP ® (
Y
page 65)
when pulling away with snow chains fitted. This
way you can allow the wheels to spin in a con-
trolled manner, achieving increased driving
force (cutting action).

G
WARNING
Underinflated or overinflated tyres pose the
following risks:
R
the tyres may burst, especially as the load
and vehicle speed increase.
R
the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and
check the tyre pressure of all the tyres includ-
ing the spare wheel:
R
at least every two weeks
R
when the load changes
R
before embarking on a longer 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.
R
Check the tyre for foreign objects.
R
Check whether the wheel is losing air or the
valve is leaking.
