Air conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.GWarning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
Deactivating
It is possible to deactivate the air
conditioning. The interior air will then no
longer be cooled or dehumidified.
XPress button ¿.

i The evaporator will be vented when the
air conditioning has been in use.
Approximately 1 hour after locking the
vehicle, the blower switches on
automatically. The blower will run for
30 minutes at its lowest level. The blower
noise is normal and not an indication of a
malfunction. When you unlock the vehicle
in the meantime, venting will be
interrupted. If the vehicle battery is low,
automatic evaporator venting will not occur
in order to preserve the battery.
Automatic mode
When operating the climate control system in
automatic mode, the interior air temperature,
air volume and air distribution are adjusted
automatically.
In automatic mode, cooling with
dehumidification is switched on. This function
can be switched off if necessary.
GWarning!

ROnly 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.
i When driving with snow chains, you may
wish to switch off the ESC ( Y page 62)
before setting the vehicle in motion. This
will improve the vehicle’s traction.
Winter driving instructions
GWarning!
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.
GWarning!
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.
GWarning!
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 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 347).
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
bring road-salt-impaired braking efficiency
back to normal.
If the vehicle is parked after being driven on
salt-treated roads, the braking efficiency
should be tested as soon as possible after
driving is resumed.GWarning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Driving instructions
Drive sensibly - save fuel
To save fuel you should:
R Keep tires at the recommended inflation
pressures.
R Remove unnecessary loads.
R Allow engine to warm up under low load
use.
R Avoid frequent acceleration and
deceleration.
R Have all maintenance work performed at
the intervals specified in the Maintenance
Booklet and as required by the
Maintenance system. Contact an
authorized Mercedes-Benz Center.

and the safety of others, we recommend that
you pull over to a safe location and stop
before placing or taking a telephone call.
If you choose to use the telephone 11
while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the COMAND 11
(Cockpit
Management and Data System) if road,
weather and traffic conditions permit.
Otherwise, you may not be able to observe
traffic conditions and could endanger yourself
and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the
engine should, therefore, be carried out only
by qualified Mercedes-Benz Center
authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service
procedures must be carried out regularly
according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet.
GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Maintenance
Notes
The Maintenance System in your vehicle
tracks the distance driven and the time
elapsed since the last maintenance service.
It calculates other maintenance service work
required, and calls for the next maintenance
service accordingly.
We strongly recommend that you have your
vehicle serviced at an authorized Mercedes-
Benz Center. Have it serviced in accordance
with the Maintenance Booklet at the times
called for by the maintenance service
indicator.
i Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
