WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Y
page 138).
i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (
Y
page 90). 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.
