Visit a qualified specialist workshop. Setting climate control to automatic
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

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.
