General notes
If you deactivate the "Cooling with air-dehumid-
ification" 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.
The "Cooling with air dehumidification" function
is only available when the engine is running. The
air inside the vehicle is cooled and dehumidified
