Overview of the climate control sys-
tem
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Ractivate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The "Cooling with air dehumidification" function
is only available when the engine is running.
Optimum operation is only achieved when the
side windows and the sliding sunroof are closed. The climatic comfort deteriorates whilst the slid-
ing sunroof is open. Set the temperature man-
ually if the sliding sunroof is open.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 102).
The integrated filter can filter out most particles
of dust and completely filters out pollen. A clog-
ged filter reduces the amount of air supplied to
the vehicle interior. Depending on the operating
conditions and environmental influences, the
interval for replacing the filter may be shorter
than specified.
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 70). This will speed
up the cooling process and the desired vehi-
cle interior temperature will be reached more
quickly.

General notes
In automatic mode, the set temperature is main-
tained at a constant level. The system automat-
ically regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode works best when cooling with
air dehumidification is also activated. If neces-
sary, cooling with air dehumidification can be
deactivated.
