Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 24).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could
otherwise fog up.
To preven tthe 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
dehumidification 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.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 85).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter filters out most
particles of dust and soot and completely filters out pollen. It also reduces gaseous
pollutants and odors.
Aclogged filter
reduces the amoun tofair 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. 120

Automatic climate control The following contains notes and
recommendations on optimum use of dual-
zone automatic climate control.
R
Activate climate control using the 0003and
0004 buttons. The indicator lamps in the
0003 and0004 buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "windshield defrosting"
function briefly until the windshield is clear
again. R
Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well.T he
indicator lamp in the 0002button goes out.

air dehumidification
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.

General notes In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
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.
