General notes
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
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperatureselected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc- tion.
