Winter driving
General information
Have your vehicle winterized at an authorized
Mercedes-Benz Center.
Winter tires
Always use winter tires at temperatures
below 45‡ (7†) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflakeimarking on the tire sidewall.
These tires meet specific snow traction
performance requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC) and
have been designed specifically for use in
snow conditions. Use of winter tires is the
only way to achieve the maximum
effectiveness of your vehicle’s driving safety
systems such as the ABS and the ESC in
winter operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
G
Warning!
Winter tires with a tread depth of less than
1
/
6
in (4 mm) must be replaced. They are no
longer suitable for winter operation.
For information on winter tires for your
vehicle model, see the “Technical data”
section (
Always observe the speed rating of the winter
tires installed on your vehicle.
After installing winter tires:
X

Vehicle speeds of up to 149 mph
(240 km/h) with winter tires of version 1:
As opposed to the information given on the
tire inflation pressure label on the inside of
the fuel filler flap, the tire inflation pressure
can be reduced by
R
front -30 kPa (0.3 bar, 4 psi)
R
rear -90 kPa (0.6 bar, 9 psi)
The continuous-travel comfort increases
while the fuel consumption may be
increased slightly.
Snow chains
!
Some tire sizes do not leave adequate
clearance for snow chains. To help avoid
serious damage to your vehicle or tires,
make sure the use of snow chains is
permissible as specified in the “Technical
data” section of this Operator’s Manual.
Snow chains should only be driven on snow-
covered roads at speeds not to exceed
30 mph (50 km/h). Remove chains as soon
as possible when driving on roads without
snow.
Observe the following guidelines when using
snow chains:
R
Use of snow chains is not permissible with
all wheel/tire combinations (
R
Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
!
If snow chains are mounted to the front
wheels, they may scrape against the body
or axle components. The tires or the vehicle
could be damaged as a result.
