General notes
Automatic mode is only available with 3-zone
automatic climate control.
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" func-
tion is activated. If necessary, cooling with air
dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" 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, deactivate the
cooling with air-dehumidification function only
briefly.
