Information on M+S tires
Use winter tires or all-season tires at tempera‐
tures below 50 °F (10 °C). Both types of tire are
identified by the M+S marking.
Only winter tires bearing the i snowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tires will allow driving safety systems
®
such as ABS and ESP
winter. These tires have been developed specifi‐
cally for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteristics.
Always observe the maximum permissible speed
specified for the M+S tires you have installed
(
page 307).
/
If you install M+S tires that have a lower maxi‐
mum 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 winter tires, take the
following measures:
Check the tire pressure (

Notes on snow chains
& WARNING Risk of accident due to incor‐
rect installation of 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.
This could cause damage to the vehicle or the
tires.

to function optimally in
page 296)
/
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 to the outer wheels.
& WARNING Risk of accident due to
unsuitable snow chains
Vehicles with all-wheel drive do not have suf‐
ficient clearance on the front axle for com‐
mercially available snow chains.
When you install commercially available snow
chains, the snow chains may come loose and
damage chassis components or brake hoses.
Only install snow chains 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 informa‐
tion about snow chains from any qualified spe‐
cialist workshop.
* 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:
Snow chains are only permissible for certain
R
wheel/tire combinations. You can obtain
information on them at a qualified specialist
workshop.
For safety reasons, only use snow chains that
R
have been specifically approved for your vehi‐
cle by Mercedes-Benz, or snow chains with
the same quality standard.
The snow chains must be retightened after
R
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.
Vehicles with all-wheel drive: install snow
R
chains on the wheels on the rear axle. On
vehicles with twin tires, install the snow
chains on the outer wheels. Observe the man‐
ufacturer's installation instructions.
