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.
For information on winter tires for your
vehicle model, see the “Technical data”
section (Y page 486).
Always observe
the speed rating of the winter
tires installed on your vehicle.
Snow chains
!
When driving with snow chains, always
select the raised level of the vehicle level
control. Other settings may result in
damage to your vehicle.
!
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 (Y page 486).
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-
Benz Center will be glad to advise you on
this subject.
R
Use of snow chains may be prohibited
depending on location. Always check local
and state laws before installing snow
chains.
R
Do not use snow chains on the spare wheel.
i
When driving with snow chains, you may
wish to switch off the ESC (Y page 212)
before setting the vehicle in motion. This
will improve the vehicle’s traction.
Winter driving instructions
G
Warning!
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and death.
To assure
sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.
G
Warning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
