perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally

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 fog up more quickly. Therefore, only

cation" function briefly.
