Overview of climate control systems
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
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air. Climate control can only be operated when the
engine is running. Optimum operation is only
achieved with the side windows and roof closed.
iWhen 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.
iIt is possible that the dehumidification func-
tion of the climate control system may be
activated automatically an hour after the
SmartKey has been removed. The vehicle is
then ventilated for 30 minutes to dry the air-
conditioning system.

Optimum use of dual-zone automatic
climate control
Climate control system
The following contains instructions and recom-
mendations to enable you to get the most out of
your 3-zone automatic climate control.
RActivate climate control using the Ãand
¿ buttons on the control panel of the cli-
mate control. The indicator lamps in the Ã
and ¿ buttons light up.
RIn automatic mode, the ñbutton on the
climate control panel may be used to addi-
tionally adjust the airflow (FOCUS/MEDIUM/ DIFFUSE). The MEDIUM level is recommen-
ded.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up, since no fresh air is drawn into the vehicle in
air-recirculation mode.
RUse the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
lamp in the ábutton goes out.
