Switching cooling with air
dehumidification on/off
Cooling is operational when the engine is
running, and cools according to the selected
interior temperature for the vehicle. Cooling
also dehumidifies the air inside the vehicle
and, thereby, prevents the windows from
fogging up.
GWARNING
If you switch off cooling with
dehumidification, the vehicle will not be
cooled and the air not dehumidified in warm
weather conditions. The windows can mist up
faster. This could result in your no longer
being able to observe the traffic conditions
properly and you may cause an accident.
i Condensation may collect on the
underside of the vehicle when the cooler is
operating.
