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 Read the information on qualified
specialist workshops: ( Y page 25).Overview of climate control systems
Important safety notes
G
WARNING
Observe the settings recommended on the
following pages. The windows could
otherwise

fog up. This could prevent you from
observing the traffic conditions, thereby
causing an accident. G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its

scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at a qualified specialist workshop.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally when the side windows and the roof
are closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 147). i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 94).
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. A clogged 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.
Since the replacement interval 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 residual heat
function may be activated automatically an
hour after the SmartKey is removed. The
vehicle is then ventilated for 30 minutes to
dry the air-conditioning system. 138

Activating/deactivating cooling with
air dehumidification
Points to observe before use 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. This may prevent you from
observing the traffic conditions, thereby
causing an accident.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
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.
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer.
Activating/deactivating X
To activate: press the ¿ button.
The indicator lamp above the ¿ button
lights up.
X To deactivate: press the ¿ button.
The indicator lamp above the ¿ button
goes out. The cooling with air
dehumidification function has a delayed
switch-off feature. Problems with the cooling with air
dehumidification function When you press the
¿ button, the
indicator lamp in the button flashes three
times

or remains off. You can no longer switch
on the cooling with air dehumidification
function.
X Visit 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 constant level.
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.

Rear window defroster
Activating/deactivating G
WARNING
Clear all windows of ice or snow before setting
off. Otherwise, impaired visibility could
endanger you and others.
The
rear window defroster has a high current
draw. You should therefore switch it off as
soon as the rear 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 2 in the
ignition lock.
X Press the ¤ button.
The indicator lamp above the ¤ button
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. Activating/deactivating air-
recirculation mode

WARNING
At low outside temperatures, only switch over
to air-recirculation mode for brief periods.
Otherwise, the windows could fog up, thus
impairing visibility and endangering yourself
and others. This may prevent you from
observing the traffic conditions and thereby
cause an accident. You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the
vehicle will then be recirculated.
The

operation of air-recirculation mode is the
same for all control panels.
X Turn the SmartKey to position 2 in the
ignition lock.
X To activate: press the g button.
The indicator lamp above the g button

i In
the event of high pollution levels 2
or at
high outside temperatures, air-
recirculation mode is automatically
activated. When air-recirculation mode is
activated automatically, the indicator lamp
above the g button does not light up.
Outside air is added after about
30 minutes.
X To deactivate: press the g button.
