Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Please read the information on qualified
specialist workshops (Y page 29).Overview of climate control systems
Important safety notes
G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. Aclogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a blocked filter replaced at a Mercedes-
Ben zCenter as soon as possible. G
WARNING
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
Automatic climate control controls the
temperature and the humidity in the vehicle
interior and filters undesirable substances
from the air.
Automatic climate control is only operational
when the engine is running 13
.O ptimum
operation is only achieved if you drive with the
side windows and sliding sunroof closed.
You can also set some automatic climate
contro lfunction svia COMAND (Y page 239).i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 89).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can filter out most
particles of dust, and completely filters out
pollen .Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Maintenance Booklet .As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.
i It is possible that the blower may be
activated automatically 40 minutes after
the SmartKey is removed. The vehicle is
then ventilated for 30 minutes to dry the
air-conditioning system.
13 The residual heat function can only be activated/deactivated if the ignition is switched off. 262

Activating/deactivating
X
Turn the SmartKey to position 2in the
ignition lock.
X To activate: press the^rocker switch
up or down.

X To deactivate: press the^rocker
switch up or down.
The indicator lamp in the rocker switch
lights up. Activating/deactivating cooling with
air dehumidification
Important information The cooling with air dehumidificatio
nfunction
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected. G
WARNING
If you switch off the cooling function, the
vehicle will no tbe cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
You can activate or deactivate the cooling
with air dehumidification function via
COMAND (Y page 241).
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. Problems with the cooling with air
dehumidification function If you can no longer switch on the cooling with
air dehumidification function via COMAND,
the cooling with air dehumidification function
is switched off due to a malfunction.
X Consult a qualified specialist workshop. Setting climate control to automatic
G
WARNING
If you switch off the cooling function, 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.
In automatic mode, the set temperature is
maintained automatically at a constan tlevel.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If desired, cooling with air
dehumidification can be deactivated.

Activating/deactivating G
WARNING
Any accumulation of snow and ice should be
removed from the rear window before driving.
Visibility could otherwise be impaired,
endangering you and others.
The rear window defroster has a high current
draw. You should therefore switch it off as
soon as the window is clear. Otherwise, the
rear window defroster switches off
automatically after several minutes.
If the battery voltage is too low, the rear
window defroster may switch off.
X Turn the SmartKey to position 2in the
ignition lock.
X Press the ¤rocker switch up or down.
The indicator lamp in the ¤rocker
switch lights up or goes out.
Problems with the rear window
defroster The rear window defroster has deactivated
prematurely or cannot be activated.
X
Switch off any consumers that are not
required, e.g. reading lamps or interior
lighting.
When the battery is sufficiently charged,
the rear window defroster is activated
again automatically. 266
Operating the climate control systemsClimate control

Setting the air vents
Important safety notes
G
WARNING
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature). This
could cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air intake grille on the hood free
of blockages, such as ice, snow or leaves
R never cover the air vents or air intake grille
in the vehicle interior.
i For virtually draft-free ventilation, adjust
the sliders of the air vents to the center
position. Setting the center air vents

i Side window defroster vent :is never
completely shut, even if side air vent ;is
shut. Setting the air vents in the stowage
compartment
When automatic climate control is activated
the stowage compartmen tcan be ventilated,
for instance to cool its contents. The level of
airflow depends on the airflow and air
distribution settings. The temperature of the
air is approximately the same as that of the
air flowing from the center air vents.
! Close the stowage compartmen tair vent
when heating mode is activated and
activate "cooling with air dehumidification"
if the outside temperature is high.
Otherwise, temperature-sensitive items
stored in the stowage compartmen tcould
be damaged. 268
