Snow chains
G
WARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abra-
sion to the vehicle body or to chassis com-
ponents. This could cause damage to the
vehicle or the tires. There is a risk of an
accident.
To avoid hazardous situations:
R
never mount snow chains on the rear
wheels
R
only mount snow chains in pairs on the
front wheels.
!
On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and
tire combinations" section under "Tires and
wheels".
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 are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
If you intend to mount snow chains, please
bear the following points in mind:
R
Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (
Y
page 329).
R
Only use snow chains when driving on roads
completely covered by snow. 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 regu-
lations if you wish to mount snow chains.
R
Do not exceed the maximum permissible
speed of 30mph (50 km/h).
R
If snow chains are installed, you cannot use
Active Parking Assist (
Y
page 176).
You may wish to deactivate ESP
®
when pulling
away with snow chains installed . This allows
the wheels to spin in a controlled manner, ach-
ieving increased propulsive force (cutting
action).
R
Deactivate ESP
®
(all vehicles except
Mercedes-AMG vehicles) (

Important safety notes
G
WARNING
Underinflated or overinflated tires pose the
following risks:
R
the tires may burst, especially as the load
and vehicle speed increase.
R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R
the driving characteristics, as well as
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires
including the spare wheel:
R
monthly, at least
R
if the load changes
R
before beginning a long journey
R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
