General notes
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, only deactivate
the "Cooling with air-dehumidification" func-
tion 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 temperature
selected.
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.
