and do not provide sufficient traction. There
is a risk of an accident.
M+S tires with a tread depth of less than
ã
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡ (+7 †), use
winter tires or all-season tires. 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
®
to
function optimally in winter. 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.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
When you have mounted M+S tires:
X
Check the tire pressures (
Y
page 337).
X
Vehicles for Canada: restart the tire
pressure loss warning system
(
Y
page 337).
X
Vehicles for USA: restart the tire pressure
monitor (
Y
page 338).

emergency spare wheel, see (

Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
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 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".
!
Vehicles with steel wheels: if you wish
to mount snow chains on steel wheels,
make sure that you remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
For safety reasons, Mercedes-Benz
recommends 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.
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 359).
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).
i
You may wish to deactivate
ESP
®
(
Y
page 70) when pulling away with
snow chains installed. You can thereby
allow the wheels to spin in a controlled
manner, achieving an increased driving
force (cutting action).

emergency spare wheel, see (
