Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variation sare pos-
sible. Not ethat your vehicle may not be
equipped with all of the function sdescri-
bed. This is also the case for system sand

WARNING
Observ ethe settings recommende donthe
following pages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 132).
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the con-
venienc eopening feature (Y page 89). 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 Servic
eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. 124

Information abou
tusing
THERMOTRONIC automatic climate
control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automatic cli-
mate control.
R Activate climate control using the Ãand
¿ buttons. The indicato rlamps above
the à and¿ buttons light up.
R In automatic mode, you can also use the
ñ buttontos etac limate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM leve lisrecommended.
R Set th etem peratur eto22†.
R Only use th edemisting function briefly until
th ew indscree nisclear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in atunnel. The windows could
otherwise mist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
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-
partment as well.T he indicator lamp above
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
Points to observe before use i
If climate control is switched off, the air
supply and air circulation are also switched
off. Only use this settingf orab rief period.
The windows could otherwise mist up.
i Switch on climate control primarily using
the à button (Y page 128). Switching on/off 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 the ^button.

out. The previous settings are reactivated.
X To switch off: press the^button.
The indicator lamp in the ^button lights
up. Activating/deactivating the cooling
with air dehumidification function
Points to observe before use 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.
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.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This
is normal and not asign that there is amal-
function.
i The cooling with air dehumidification
function uses refrigerant R134a. This
refrigerant does not contain chlorofluoro-
carbons, and therefore does not damage
the ozone layer. Operating the climate control system

cooling with air dehumidification function.
X Visit aqualified specialist workshop. Setting climat
econtrol to automatic
mode
In automatic mode, the set temperature is
maintained automatically at aconstan tlevel.
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.
