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:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch 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
(
Ypage 125).
iWhen 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.
iThe 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.
iIt 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.

Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will not
be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up more
quickly. Therefore, deactivate the cooling with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. The air
inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is normal
and not a sign that there is a malfunction.
Switching on/off
XTo activate: press the¿button.
The indicator lamp above the ¿button lights up.
XTo deactivate: press the¿button.
The indicator lamp above the ¿button goes out. The "Cooling with air dehumidification"
function has a delayed switch-off feature.
Problems with the "Cooling with air dehumidification" function
ProblemPossible causes/consequences and MSolutions
The indicator lamp over
the¿ button flashes
three times or remains
off. The "Cooling with air
dehumidification" func-
tion cannot be switched
on.Cooling with air dehumidification has been deactivated due to a mal-
function.
XVisit a qualified specialist workshop.
Setting climate control to automatic
General notes
In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The "Cooling with air dehumidification" function
is activated automatically in automatic mode.
