automatic climate control
The following contains instructions and
recommendations to enable you to get the
most out of your automatic climate control.
R Activate climate control using the 0006and
0007/0005 buttons. The indicator lamps
above the 0006and0007/0005 buttons
lightu p.
R In automatic mode, you can also use the
000C button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting"
function briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side and the rear
compartment as well. The indicator lamp
above the 0004button 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
residual heat function can only be activated
or deactivated with the ignition switched
off. Operating the climate control
systems
Switching climate control on/off
Points to observe before use When the climate contro
lis switched off, the
air supply and air circulation are also
switched off. The windows could fog up.
Therefore, switch off climate control only
briefly
i Switch on climate control primarily using
the 0006 button (Y page 152).
In the rear compartment, you can also switch
climate control on and off using the 0006and
000C buttons.

Activating/deactivating cooling with
air dehumidification
Points to observe before use If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will no tbe cooled. The air inside the
vehicle will also not be dehumidified. The
windows can fog up more quickly. Therefore,
only deactivate the "Cooling with air-
dehumidification" function briefly.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
Activating/deactivating Example:
0007button
X To activate: press the0007/0005 button.
The indicator lamp in the 0007/0005
button lights up.
X To deactivate: press the0007/0005
button.
The indicator lamp in the 0007/0005
button goes out. The "Cooling with air
dehumidification" function has a delayed
switch-off feature. Operating the climate control systems

Problems with the "Cooling with air dehumidification" function
Problem Possible causes/consequences and
0001 Solutions
The indicator lamp in
the
0007/0005 button
flashes three times or
remains off. The
"Cooling with air
dehumidification"
function cannot be
switched on. Cooling with air dehumidification has been deactivated due to a
malfunction.

Points to observe before use If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will not be cooled. The air inside the
vehicle will also not be dehumidified. The
windows can fog up more quickly. Therefore,
only deactivate the "Cooling with air-
dehumidification" function briefly.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If necessary, cooling with air
dehumidification can be deactivated.
In the rear compartment, you can also switch
climate control for the rear seats to automatic
mode using the
0006button. Activating/switching X

Switch off any consumers that are not required, e.g. reading
lamps or interior lighting.
When the battery is sufficiently charged, the rear window
defroster is activated again automatically. Activating/deactivating air-
recirculation mode
Points to observe before use You can deactivate the flow of fresh air if
unpleasant odors are enteringt he vehicle
from outside. The air already inside the
vehicle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
Activating/deactivating The operation of air-recirculation mode is the
same for all control panels.

ignition lock (Y page 163).
X To activate: press the0016button.

i In the event of high pollution levels (3-
zone automatic climate control only) or at high outside temperatures, air-
recirculation mode is automatically
activated. When air-recirculation mode is
activated automatically, the indicator lamp
in the
0016button is not lit.
Outside air is added after about
30 minutes.
