Activating/deactivating the cooling
with air dehumidification function
Points to observe before use
If you deactivate the "Cooling with air dehu-
midification function", the air inside the vehi-
cle will not be cooled in warmer weather. The
air inside the vehicle will not be dehumidified
either. The windows can mist up more
quickly. Therefore, only switch off the "Cool-
ing with air dehumidification function" briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
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.
