Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.

WARNING
Observe the settings recommended on the
following pages. Otherwise, th ewindows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident.
The air-conditioning system/
THERMOTRONIC automatic climate control
controls the temperature and the humidity of
the vehicle interior and filters undesirable
substances fro mthe air.
The air-conditioning system/
THERMOTRONIC automatic climate control is
only operational when the engine is run-
ning. 8
The function only works optimally when
the side windows and the roof are closed.
i Ventilate the vehicle for a brief period
during warm weather. 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 Service Booklet
.As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
8 The residual heat function can only be activated/deactivated when the ignition is switched off. 114

R Switch on climate control using the ¿
button. The indicator lamp in the ¿but-
ton lights up.
R Set the temperature to 22 †.
R Recommendation for air distribution in
winter: set theOand¯ settings.
Recommendation for air distribution in
summer: set thePsetting.
R Only use the demisting function briefly,
until the windscreen is clear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasan toutside odours or when in a tunnel. The windows could
otherwise mis
tup as no fresh air is drawn
into the vehicle in air-recirculation mode. Overview of climate control systems

or when in a tunnel. The windows could
otherwise mist up as no fresh air is drawn
into the vehicle in air-recirculation mode.

partment as well. The indicator lamp in the

R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The resid-
ual heat function can only be activated or
deactivated with the ignition switched off. Operating the climate control system
Switching climate control on/off
Important information i
When climate control is switched off, the
air supply and air circulation are also
switched off. Only select this setting
briefly. Otherwise, the windows may mist
up.
i Switch on climate control primarily using
the à button (Y page 118).

with air dehumidification function
Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
G
WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when THERMOTRONIC is in cool-
ing mode. This is normal and not a sign that
there is a malfunction.
Depending on the equipment level, the con-
trol panel has either the Ábutton or the
¿ button.
i The cooling with air dehumidification
function uses refrigerant R134a. This cool- Operating the climate control system

Problems with the cooling with air
dehumidification function When you press the
¿orÁ button, the
indicator lamp in the button flashes three
times or remains off. You can no longer switch
on the cooling with air dehumidification func-
tion.
X Consult a qualified specialist workshop. Setting climate control to automatic
mode
Only THERMOTRONIC automatic climate con-
trol features the "control climate control
automatically" function.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
Automatic mode will achieve optimal opera-
tion if cooling with air dehumidification is also
activated. If desired, cooling with air dehu-
midification can be deactivated. X
