Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" 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, deactivate the cooling with air-dehumidification function only briefly.
For vehicles without a hybrid drive system, the "Cooling with air dehumidification" function is avail-
able when the engine is running. For hybrid vehicles, the "Cooling with air dehumidification" function
is also available via the electric refrigerant compressor when the engine is not running. 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 malfunction.
