Air conditioning
The air conditioning (cooling) function is
operational when the engine is running and
cools the vehicle interior down to the se-
lected temperature. In addition, the cool-
ing function dehumidifies the air in the
vehicle interior, thus preventing the win-
dows from fogging up.Deactivating
It is possible to deactivate the cooling
function of the automatic climate control
system. The air in the vehicle will then no
longer be cooled or dehumidified.

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

Before operating the retractable hardtop
switch, make sure there is no danger of any-
one being injured by the moving parts (re-
tractable roof, roof frame, and trunk lid) due
to inattention.
