automatic climate control
The following contains notes and recommen-

matic climate control.
R Activate climate contro lusing the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Set the temperature to 22 †.
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 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 ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well.T he indi-

Activating/deactivating the cooling with air dehumidification function
Points to observe before use G
WARNING
If the "cooling with air dehumidification" function is deactivated, the air inside the vehicle will not
be cooled (during warm weather) or dehumidified. The windows could mis tup more quickly. This
may prevent you from observing the traffic conditions, thereby causing an accident.
The cooling with air dehumidification function is only available when the engine is running.
The air inside the vehicle is cooled and dehumidified according to the temperature selected.
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 malfunction.
i The cooling with air dehumidification function uses refrigerant R134a. This refrigerant does
not contain chlorofluorocarbons, and therefore does not damage the ozone layer.

X Visit a qualified specialist workshop. Setting climate control to automatic
mode
In automatic mode, the set temperature is
maintained at a constant level. The system
automatically regulates the temperature of
the dispensed air, the airflow and the air dis-
tribution. 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.130
