To avoid hazardous situations:
R
never install snow chains to the front
wheels
R
always install snow chains in pairs to the
rear wheels.
!
Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
R
wheel
R
wheel housing
R
wheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
!
You must drive at raised vehicle level (height
1) if snow chains have been installed. The
vehicle may otherwise be damaged.
!
Vehicles with ADS (Adaptive Damping
System): do not use the sport mode when
driving with snow chains mounted. The vehi-
cle 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 are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
Install the snow chains on all driven wheels for
maximum tractive power and driving stability. If
you own snow chains for two driven wheels only,
install the snow chains to the wheels on the rear
axle. The vehicle then remains more stable
under braking.
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 377).
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 regulations if
you wish to mount snow chains.
R
Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
R
When snow chains are installed, never use
Active Parking Assist (Y page 192) or the
Parking Package with rear view camera.
You may wish to deactivate ESP
®
(Y page 71)
when pulling away with snow chains mounted.
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv-
ing force (cutting action).

spare wheel (Y page 378).

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 steer-
ing 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 includ-
ing 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.
Details on tire pressure can be found at the fol-
lowing positions in the vehicle:
R

B-pillar on the driver's side
