(26 °C) the system will not automatically
switch back to outside air.
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.

iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!
G
If you turn off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog
up more quickly. Window fogging may
impair visibility and endanger you and

which are harmful to the ozone layer.
Residual heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.Activating
