Climate control
General notes
THERMOTRONIC 2-zone automatic climate
control controls the temperature and the
humidity of the vehicle interior and filters out
undesirable substances fro mthe air.
THERMOTRONIC 2-zone automatic climate
control is only operational when the engine is
running. Optimum operation is achieved only
when you drive with the side windows closed.
i When the weather is warm, ventilate the
vehicle for a brief period. 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. G
Risk of accident
Observe the settings recommended on the
following pages. Otherwise, the windows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident. Climate control

Only use air-recirculation mode briefly, e.g. if there are unpleasant outside odours or when
in a tunnel. The windows could otherwise mist up as in air-recirculation mode no fresh air
is drawn into the vehicle.

tings from the driver's side for all air-conditioning zones. The indicator lamp in the
0005 button lights up. Switching climate control on/off

fication on/off
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
Risk of accident
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 prevent you 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.

In automatic mode, the set temperature is
controlled automatically. The system auto-
matically regulates the temperature of the
dispensed air, the airflow and the air distri-
bution.
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.
