212 Controls in detailDual-zone automatic climate control (USA only)Air conditioning
The cooling function, only operational
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up.Deactivating

tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.

neath the vehicle. This is normal and
not an indication of a malfunction.Warning!

vehicle will not be cooled when weather
conditions are warm. The windows can fog
up more quickly. Window fogging may

ditioning is losing refrigerant. The com-
pressor has turned itself off.
