Overview of climatecontrol systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preventt he 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
engin eisrunning. Optimum operation is only
achieved with the side windows and roof closed.
iWhen the weather is warm, ventilate the
vehicle for abrief period. This will speed up
the cooling process and the desired vehicle
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. Aclogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alwayso bserve
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.

Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find anumber of notes and rec-
ommendations to help you use the air-condi-
tioning system optimally.
RSwitch on cooling with air dehumidification
using the ¿button. The indicator lamp in

ROnly use the "Windshield defrosting" function
briefly until the windshieldisc lear again.
ROnly use air-recirculation mode briefly,e .g. if
there are unpleasant outside odors or when in
at unnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
ECO start/stop function

Setting climate control to automatic
General notes
Automatic mode is only available with 3-zone
automatic climate control.
In automatic mode, the set temperature is main-
tained automatically at aconstant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The automatic mode functions optimally when
the "Cooling with air dehumidification" function
is activated. If necessary, cooling with air dehu-
midification can be deactivated.
If you deactivate the "Cooling with air-dehumid- ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified.T he windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
