Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature ( page 108). This will
Y
speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i
The integrated filter filters out most par-
ticles 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. The windows could other-
wise mist up. This may obstruct your view
of the traffic situation, thereby causing an
accident.
