climate control
The following contains notes and recommen-
dations on optimum use of THERMATIC auto-
matic climate control.
R Switch on the air-conditioning system by
turning control knob Aclockwise to the
desired position (except position 0).
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

with air dehumidification function
Important information 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 prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
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.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This
is normal and not a sign that there is a mal-
function.
i The refrigerant that is used by the cooling
with air dehumidification does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. You can obtain
more detailed information on refrigerants
from any qualified specialist workshop.

Problems with the cooling with air
dehumidification function
When you press the
¿button, the indica-
tor lamp in the button flashes three times or
remains off. You can no longer switch on the
cooling with air dehumidification function.
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.
