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.
i Please read the information on qualified
specialist workshops (Y page 22).Overview of climate control systems

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

button. The indicator lamp in the ¿but-
ton lights up.

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

mate control.
R Activate climate control using the Ãand
Á buttons .The indicator lamps in the
à andÁ buttons light up.

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

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

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.
