possible when you come to a road that is
not snow-covered.
Local regulations may restrict the use of
R
snow chains. Observe the appropriate
regulations if you wish to mount snow
chains.
Do not exceed the maximum permissible
R
speed of 30 mph (50 km/h).
Snow chains must not be mounted on
R
emergency spare wheels.

You may wish to deactivate
®
ESP ( page 56) when pulling away with
Y
snow chains installed. You can thereby
allow the wheels to spin in a controlled
manner, achieving an increased driving
force (cutting action).

M+S tires

G WARNING
M+S tires with a tread depth of less than
inch (4 mm) must be replaced. They are no
longer suitable for winter operation.
G
WARNING
If you mount the spare wheel when driving
with M+S tires, bear in mind that driving
stability will be impaired due to unstable
cornering characteristics caused by the
different tire characteristics. Adapt your style
of driving accordingly.
Have the spare wheel replaced by a normal
wheel with an M+S tire at the nearest
Mercedes-Benz Center.
At temperatures below 45 ‡ (+7 †), use all-
season tires or winter 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
function optimally in winter. This is because
these tires were specifically developed 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 the M+S tires:
Check the tire pressures (

G WARNING
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
1 / wear excessively and/or unevenly, adversely
6
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
You will find a table of recommended tire
pressures on the Tire and Loading
Information placard on the B-pillar on the
driver's side (

conditions on the inside of your vehicle's fuel
filler flap.
