Winter driving
General information
Have your vehicle winterized at an authorized
Mercedes-Benz Center.
Winter tires
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.
G
Warning!
If you use your spare wheel when winter
tires are fitted on the other wheels, be
aware that the difference in tire character-
istics may very well impair turning stability
and that overall driving stability may be
reduced. Adapt your driving style accord-
ingly.
Have the spare wheel replaced by regular
road wheel with a winter tire at the nearest
authorized Mercedes-Benz Center.
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/
snowflake.marking on the tire sidewall.
These tires meet specific snow traction per-
formance requirements of the Rubber Manu-
facturers Association (RMA) and the Rubber
Association of Canada (RAC) and have been
designed specifically for use in snow condi-
tions. 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 ESP
®
in winter operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
Always observe the speed rating of the winter
tires installed on your vehicle. If the maximum
speed for which your tires are rated is below
the speed rating of your vehicle, you must
place a notice to this effect where it will be
seen by the driver. Such notices are available
at your tire dealer or any authorized Mer-
cedes-Benz Center.
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 per-
missible 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 (Y page 345).
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.
R
Only use snow chains that are approved by
Mercedes-Benz. Any authorized Mercedes-
