Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R
switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R
switch on the defrost windshield function
briefly, if required
The climate control/dual-zone automatic
control regulates the temperature and the
humidity of the vehicle interior and filters out
undesirable substances from the air.
Climate control/dual-zone automatic climate
control is only operational when the engine is
running. Optimum operation is only achieved
with the side windows and panorama roof
with power tilt/sliding panel closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Y
page 135).
Always keep the ventilation flaps behind the
side trim panel in the cargo compartment
clear (
Y
page 117). Otherwise the vehicle will
not be ventilated correctly.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (
Y
page 88). This
will 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 soot and completely fil-
ters out pollen. With dual-zone automatic
climate control, gaseous pollutants and
odors will also be reduced. 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 Mainte-
nance Booklet. As it depends on environ-
mental conditions, e.g. heavy air pollution,
the interval may be shorter than stated in
the Maintenance Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the SmartKey has been removed in
order to dry the air-conditioning system.
The vehicle is then ventilated for
30 minutes.
