Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
switch off climate control only briefly
R
activate air-recirculation mode only briefly
R
switch on "Cooling with air dehumidification"
R
activate the windscreen demisting function
R
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The "Cooling with air dehumidification" function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
The residual heat function can only be activated
or deactivated with the ignition switched off
(

The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odours. A clogged 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 this
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.

It is possible that the blower may be activa-
ted automatically 60 minutes after the key
has been removed depending on various fac-
tors, e.g. the outside temperature. The vehi-
cle is then ventilated for 30 minutes to dry the
automatic climate control.
