Switching cooling with air-dehumidi-
fication on/off
The "cooling with dehumidification" function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted. This prevents the windows from misting
up.
G Risk of accident
If the "cooling with air dehumidification"
function is deactivated, the air inside the
vehicle will not be cooled (during warm
weather) or dehumidified. The windows
could mist up more quickly. This may pre-
vent you from observing the traffic condi-
tions, thereby causing an accident.
