air dehumidification
General notes G
WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. This may prevent you from
observing the traffic conditions, thereby
causing an accident.
The cooling with air dehumidification function
is only available when the engine is 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.
i The refrigerant that is used by the cooling
with air dehumidification does not contain
chlorofluorocarbons and therefore does
not damage the ozone layer. Operating the climate control systems
