Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise 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 dehumidifica-
tion function
R
switch on the defrost windshield function
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 activated
or deactivated with the ignition switched off
(

When the weather is warm, ventilate the
vehicle for a brief period. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.

The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
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 Book-
let.
i
It is possible that the residual heat function
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.
