Activating/deactivating the cooling
with air dehumidification function
Important information
G WARNING
If the "cooling with air dehumidification" func-
tion 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 prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
The cooling with air 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.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This
is normal and not a sign that there is a mal-
function.
i
The refrigerant that is used by the cooling
with air dehumidification does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. You can obtain
more detailed information on refrigerants
from any qualified specialist workshop.
Switching on/off
