Only these tires allow driving safety systems such
as ABS and ESP
®
to also function optimally in win-
ter. These tires have been developed specifically
for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteristics.
Observe the maximum permissible speed specified
for the M+S tires you have installed (
/
page 255).
If you install M+S tires that have a lower maximum
permissible speed than the maximum design
speed of the vehicle, affix an appropriate warning
sign in the driver's field of vision. You can obtain
this at a qualified specialist workshop.
Once you have installed the M+S tires, take the fol-
lowing measures:
R
check the tire pressure (

WARNING Risk of accident due to incor-
rectly installed snow chains
Vehicles with rear-wheel drive: if you have
installed snow chains to the front wheels, they
may drag against the vehicle body or chassis
components.
#
Never install snow chains on the front
wheels.
#
Only install snow chains on the rear
wheels in pairs.
#
Vehicles with twin tires: install the snow
chains on the outer wheels.
&
WARNING Risk of accident due to unsuita-
ble snow chains
Commercially available snow chains can come
loose and damage chassis components or
brake hoses.
#
Only install snow chains that have been
approved by Mercedes-Benz for these
tires.
For safety reasons, Mercedes-Benz recommends
that you only use snow chains that have been
checked and approved. You can obtain information
about snow chains from any qualified specialist
workshop.

WARNING Risk of accident due to snow
chains breaking
If you drive too fast with snow chains, they can
break, injure other persons, and damage the
vehicle.

NOTE Damage to the wheel trim from
mounted snow chains
If snow chains are mounted to steel wheels,
the wheel trims can be damaged.
#
Remove the wheel trims of steel wheels
before mounting snow chains.
Observe the following notes when using snow
chains:
R
Snow chains are only permissible for certain
wheel/tire combinations. You can obtain infor-
mation on this at a qualified specialist work-
shop.
R
For safety reasons, only use snow chains that
have been specifically approved for your vehi-
cle by Mercedes-Benz, or snow chains with the
same quality standard.
R
The snow chains must be retightened after
driving approximately 0.6 miles (1 km). This is
the only way to ensure the snow chains are
optimally seated with clearance to adjacent
components.
R
Vehicles with all-wheel drive: install snow
chains on the wheels on the rear axle. On vehi-
cles with twin tires, install the snow chains on
the outer wheels. Observe the manufacturer's
installation instructions.
R
Use snow chains only when 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 applicable regulations
before installing snow chains.
R
Activate all-wheel drive before driving off with
snow chains (

If snow chains are installed, the maximum per-
missible speed is 30 mph (50 km/h).
R
Vehicles with Parking Assist: do not use Park-
ing Assist PARKTRONIC if snow chains are
installed.
