X Visit aqualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is
maintained automatically at
aconstant 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"
function is activated. If desired, cooling with
air dehumidification can be deactivated.
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 mist up more quickly. Therefore,
deactivate the "Cooling with air-dehumidifi-
cation" function only briefly.
