Operation Manual

To avoid hazardous situations:
R
never install snow chains to the front
wheels
R
always install snow chains in pairs to the
rear wheels.
!
On vehicles with AIRMATIC, you must drive
at raised vehicle level if snow chains have
been mounted. The vehicle may otherwise be
damaged.
!
On some tire sizes there is not enough space
for snow chains. To avoid damage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" 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, con-
tact 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 325).
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 31 mph (50 km/h).
i
You may wish to deactivate ESP
®
when pull-
ing away with snow chains installed:
R
All vehicles (except Mercedes‑AMG vehi-
cles) (

R
Mercedes-AMG vehicles: (Y page 71)
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased
driving force (cutting action).

Important safety notes

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.
The data on the Tire and Loading Information
placard and tire pressure table shown here are
examples. Tire pressure specifications are vehi-
cle-specific and may deviate from the data
shown here. The tire pressure specifications
that are valid for your vehicle can be found on
the Tire and Loading Information placard and
tire pressure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
