Snow chains
! Vehicles with Adaptive Damping System
(ADS):
When driving with snow chains, do not
select SPORT mode as this 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 347).
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 ESP ®
(Y page 65)
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.
Indicated temperatures just above the
freezing

point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges. G
Warning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result

in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
The most important rule for slippery or icy
roads is to drive sensibly and to avoid abrupt
acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, shift
the automatic transmission to neutral
position N. Try to keep the vehicle under
control by corrective steering action.
i For information on driving with snow
chains, see “Snow chains” ( Y page 252).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal brake effect.
Depressing the brake pedal periodically when
traveling at length on salt-strewn roads can 252

a wheel change such as a jack or a wheel
wrench. Some tools required for a wheel
change are specific to your vehicle.

Safety notes
Your vehicle may be equipped with an
MOExtended system or a spare wheel with
collapsible tire. Vehicles with an MOExtended
system do not have a spare wheel or a TIREFIT
kit.
For information on your vehicle’s equipment,
see “Rims and tires” ( Y page 347). G
Warning!
The dimensions of the spare wheel are
different from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style
accordingly.
The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Contact the nearest authorized Mercedes-
Benz Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never operate the vehicle with more than one
spare wheel mounted. Flat tire

wheel is mounted. G
Warning!
Vehicles with AIRMATIC:
Do not open or close any doors or the tailgate
while mounting a spare wheel. The vehicle
could rise or lower to a previously selected
level. You or others could be injured as a
result. Preparing the vehicle
X Vehicles with AIRMATIC:
Make sure the vehicle level is set to
highway level

(Y page 153).
X Whenever possible, park the vehicle in a
safe

distance from moving traffic on a hard,
flat surface.
X Turn on the hazard warning flasher.
X Turn the steering wheel so that the front
wheels are in a straight-ahead position.
X Engage the parking brake.
X Shift the automatic transmission into park
position P.
X Turn off the engine.
X Remove the SmartKey from the starter
switch.
or
X Vehicles with KEYLESS-GO: Open the
driver’s

door (this puts the starter switch in
position 0, same as with the SmartKey
removed from the starter switch). The
driver’s door can then be closed again.
Open doors only when conditions are safe
to do so.
X Vehicles with KEYLESS-GO: Remove the
KEYLESS-GO start/stop button from the
starter switch.
X Have any passenger exit the vehicle at a
safe distance from the roadway. Open
doors only when conditions are safe to do
so.
i Vehicles retrofitted with TIREFIT kit: Only use the power outlet in the second-
row footwell for electric air pump
operation.
You can use the power outlet even when
the ignition is switched off, e.g. in order to
inflate the collapsible tire.
An emergency shut-off feature is designed
to prevent the vehicle’s on-board voltage
from dropping below a minimum level. If
the on-board voltage drops to this
minimum level, the power outlets are
switched

off automatically to help preserve
engine starting power. Sealing tires with TIREFIT
This section applies to vehicles retrofitted
with a TIREFIT kit only.
Small

tire punctures, particularly those in the
tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient temperatures
down to -4‡ (-20†). G
Warning!
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage

caused by driving with extremely low
tire inflation pressure, or on a flat tire, or a
damaged wheel.
Do not drive the vehicle under such
circumstances.
Contact the nearest authorized Mercedes-
Benz Center for assistance or call Roadside
Assistance.
X Foreign objects (e.g. screws or nails)
should not be removed from the tire.
X Take the TIREFIT kit, the sticker, and the
electric air pump out of the vehicle. 320
