Air conditioning
General notes
The automatic air conditioning controls the
temperature and the humidity of the vehicle
interior and filters out undesirable substan-
ces from the air.
The automatic air conditioning is only opera-
tional when the engine is running.
38
Optimum
operation is only achieved when you drive
with the side windows and sliding/tilting sun-
roof*/panorama sliding sunroof* closed.
i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (
Y
page 216).
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. 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 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.

The "residual heat" function can only be switched on/off if the ignition is switched off.
