General notes

Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
switch off climate control only briefly
R
switch on air-recirculation mode only
R
briefly
switch on the cooling with air dehumidifi-
R
cation function
switch on the defrost windshield function
R
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof
closed.
The residual heat function can only be acti-
vated or deactivated if the ignition is switched
off (see the Digital Operator's Manual, key-
word "Residual heat").
i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (see the Digital
Operator's Manual, keyword "Convenience
opening"). This will speed up the cooling

process and the desired interior tempera-
ture will be reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odors. 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 Maintenance
Booklet. As it depends on environmental
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 is removed. The vehicle
is then ventilated for 30 minutes to dry the
automatic climate control.
