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.
i Read the information on qualified special-
ist workshops: (Y page 25). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R activate the "Cooling with air dehumidifica-
tion" function
R activate the windscreen demisting function
briefly, if required
The air-conditioning system/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters undesirable
substances from the air.
The air-conditioning system/
THERMOTRONIC automatic climate control
can only be operated when the engine is run-
ning. Optimum operation is only achieved
with the side windows and panorama sliding
sunroof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 155).
Always keep the ventilation flaps behind the
side panelling clear (Y page 136). Otherwise
the vehicle will not be ventilated correctly. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 102).
This will speed up the cooling process and
the desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. With THERMOTRONIC auto-
matic climate control, gaseous pollutants
and odours will also be reduced. A clogged
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 this depends on envi-
ronmental conditions, e.g. heavy air pollu-
tion, the interval may be shorter than stated in the Service Booklet.
i Vehicles with auxiliary heating:
under
certain environmental conditions, the
residual heat function may be activated
automatically an hour after the key has
been removed in order to dry the automatic climate control. When the automatic cli-
mate control drying function is active, the
blue LED lamp is lit in the rocker switch in
the centre console. The vehicle is then ven-
tilated for 30 minutes.
Vehicles without auxiliary heating:
under certain environmental conditions,
the residual heat function may be activated automatically an hour after the key has
been removed in order to dry the automatic
climate control. The vehicle is then ventila-
ted for 30 minutes. 144

system
Air-conditioning system Below, you can find a number of tips and rec-
ommendations for optimum use of the air-
conditioning system.
R Switch on the air-conditioning system by
turning control knob Aclockwise to the
desired position (except position 0).
R Set the temperature to 22 †.
R Recommendation for avoiding misted
windows at low exterior temperatures
or in rain: switch on the ¿cooling with
dehumidification function (Y page 149).
Set air distribution to ¯and if possible
switch off PandO (Ypage 151).
Deactivate air-recirculation mode e
(Y page 154). Set airflow control
Ato a setting between
3 and 6(Y page 151).
R Recommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3
and 6(Y page 151).
R Recommendation for a constant vehi-
cle interior temperature: set airflow con-
trol Ato a setting between 1and 3
(Y page 151).
R Recommendation for air distribution in
winter: select the Oand¯ settings
(Y page 151).
Recommendation for air distribution in
summer: select the PorP and
¯ settings (Y page 151).
R Only use the "Windscreen demisting" func-
tion briefly until the windscreen is clear
again. Overview of climate control systems

automatic climate control
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 indicator lamps in the
à and¿ buttons light up.
R Set the temperature to 22 †. R
Only use the "Windscreen demisting" func-
tion 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 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. The indi-
cator lamp in the ábutton goes out. Overview of climate control systems

Activating/deactivating cooling with
air dehumidification
General notes If you deactivate the "Cooling with air dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only deactivate the "Cooling with air dehu-
midification" function briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of the vehicle when cooling mode is active. Thisis normal and not a sign that there is a mal-
function.
Activating/deactivating X
To activate: 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. Operating the climate control system

Problems with the "Cooling with air dehumidification" function
Problem
Possible causes/consequences and
M
MSolutions The indicator lamp in
the
¿ button
flashes three times or
remains off. The cool-
ing with air dehumidifi-
cation function cannot
be activated. The cooling with air dehumidification function has been deactiva-
ted due to a malfunction.
X Visit a qualified specialist workshop. Setting climate control to automatic
mode
General notes Only THERMOTRONIC automatic climate con-
trol features the "Control climate control
automatically" function.
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.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If desired, cooling with
air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only deactivate the "Cooling with air-dehu-
midification" function briefly.
