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 variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 25). Overview of climate control systems

WARNING
Observe the settings recommended on the
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 150).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 96). 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 has been removed. The vehi-
cle is then ventilated for 30minutes to dry
the air-conditioning system. 142

the à and¿ buttons light up.
R Set the temperature to 22 †.
R Only use the demisting function briefly until
the windscreen is clear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in a tunnel. 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 as well.T he indi-

THERMOTRONIC automatic climate
control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automati ccli-
mate control.
R Activate climate control using the Ãand
¿ buttons .The indicator lamps above
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 the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in a tunnel. 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. The 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 setting for a brief period.
The windows could otherwise mist up.
i Switch on climate control primarily using
the à button (Y page 146).

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. Operating the climate control system
145Climate control Z

Condensation may drip from the underside of
the vehicle when cooling mode is active. This
is normal and no tasign that there is a mal-
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.
Switching on/off X
To activate: press the¿button.
The indicator lamp above the ¿button
lights up.
X To deactivate: press the¿button.
The indicator lamp above the ¿button
goes out. The cooling with air dehumidifi-
cation 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 Visit 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. X
Turn the key to position 2in the ignition
lock.
X Set the desired temperature.
X To activate: press theÃbutton.
The indicator lamp above the Ãbutton
lights up. Automatic air distribution and air-
flow are activated.
