Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
available at the time of publicatio nofthe
Owner's Manual. Country-specific differen-
ces are possible. Please note that your
vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. Overview of climate control systems

Risk of accident
Observe the settings recommended on the
following pages. Otherwise, the windows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident.
THERMATIC 2-zone automatic climate con-
trol/THERMOTRONIC luxury 3-zone auto-
matic climate control controls the tempera-
ture and the humidity of the vehicle interior
and filters out undesirable substances from
the air.
THERMATIC 2-zone automatic climate con-
trol/THERMOTRONIC luxury 3-zone auto-
matic climate control is only operational
when the engine is running 24
.O ptimum oper-
ation is only achieved if you drive with the side
windows and sliding sunroof/panorama slid-
ing sunroof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 79). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged 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 Service Booklet .As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.

on/off if the ignition is switched off. 110

fication on/off
Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
G
Risk of accident
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
Condensatio nmay drip from the underside of
the vehicle when THERMOTRONIC is in cool-
ing mode. This is normal and no tasign that
there is a malfunction.
i The cooling with air dehumidification
function uses refrigerant R134a. This cool-
ant does not contain chlorofluorocarbons,
and therefore does not damage the ozone
layer. Activating/deactivating X
To switch on: press the¿button.
The indicator lamp in the ¿button lights
up.
X To deactivate: press the¿button.
The indicator lamp in the ¿button goes
out. The cooling with air dehumidification
function has a delayed switch-off feature.
Problems with the cooling with air
dehumidification function When you press the
¿button, the indica-
tor lamp in the button flashes three times or
remains off. You can no longer switch on the
cooling with air dehumidification function.
X Consult a qualified specialist workshop. Setting climate control to automatic
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
Automatic mode will achieve optimal opera-
tion if cooling with air dehumidification is also
activated. If desired, cooling with air dehu-
midification can be deactivated. Adjusts the climate control settings
This function is only available with
THERMOTRONIC luxury 3-zone automatic cli-
mate control.
The climate mode setting is especially effec-
tive at high temperatures.
You can select the following climate mode
settings in automatic mode:
FOCUS High airflow; slightly cooler setting
MEDIUM Mediuma irflow; standard setting
DIFFUSE Low airflow; slightly warmer air with less of a draught 114
