Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.

WARNING
Observe the settings recommended on the
following pages. Otherwise, th ewindows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident.
THERMATIC/THERMOTRONIC automatic cli-
mate control controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances fro mthe air.
THERMATIC/THERMOTRONIC automatic cli-
mate control is only operational when the
engine is running 12
.O ptimum operation is
only achieved when 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 97). 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.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air-
conditioning system.
12 THERMOTRONIC automatic climate control: the residual heat function can only be activated/deactivated
when the ignition is switched off. 134

Notes on using THERMOTRONIC auto-
matic climate control
Below, you can find a numbe rofnotes and
recommendations to help you use
THERMOTRONIC automatic climate control
optimally.
R Switch on climate control using the Ã
and ¿ buttons. The indicator lamps in
the à and¿ buttons light up.
R In automatic mode, you can also use the
ñ button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly until
the windscreen is clear again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up, as in air-recirculation mode,
no fresh air is drawn into the vehicle.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partmen tas well.T he indicator lamp in the
á button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The resid-
ual heat function can only be activated or
deactivated with the ignition switched off. Operating the climate control system
Switching climate control on/off
Important information i
When climate control is switched off, the
air supply and air circulation are also
switched off. Only select this setting
briefly. Otherwise, the windows may mist
up.
i Switch on climate control primarily using
the à button (Y page 138). Activating/deactivating X
Turn the key to position 2in the ignition
lock.
X To switch on: press theÃbutton.
The indicator lamp in the Ãbutton lights
up. Airflow and air distribution are set to
automatic mode.
or
X Press button ^.
The indicator lamp in the ^button goes
out. The previously selected settings come
into effect again.
X To switch off: press the^button.
The indicator lamp in the ^button lights
up. Activating/deactivating the cooling
with air dehumidification function
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
WARNING
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.
Condensation may drip from the underside of
the vehicle when THERMOTRONIC is in cool-
ing mode. This is normal and not a sign 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. Operating the climate control system

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
mode
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.
