Important safety notes
G 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.
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control
controls the temperature and the humidity of
the vehicle interior and filters out undesirable
substances from the air.
THERMATIC/THERMOTRONIC automatic cli-
mate control is only operational when the
engine is running
7
. Optimum operation is only
achieved if you drive with the side windows
and 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 81). 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.
7
THERMOTRONIC automatic climate control: the residual heat function can only be activated/deactivated
when the ignition is switched off.
