(26°C) the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
Air conditioning
The cooling function, only operational

cle down to the selected interior tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thereby preventing the windows from fog-
ging up.
iPress and hold button:for approx-
imately 2 seconds. The windows,
and/or the tilt/sliding sunroof*, (or
tilt/sliding panel*) will return to their
previous position. You can release
button:once the opening proce-
dure has begun. The windows and/or
the tilt/sliding sunroof* (or tilt/sliding
panel*) continue opening until they
have reached their previous position.
A window or the tilt/sliding sunroof*
(or tilt/sliding panel*) will only return
to its previous position if it has not
been moved to another position using
the respective window switch or
tilt/sliding sunroof* (or tilt/sliding
panel*) switch after it was closed with
button:.
A window or the tilt/sliding sunroof (or
tilt/sliding panel*) that was moved will
remain in its current position if
button:is used to re-open the re-
maining windows or tilt sliding sun-
roof* (or tilt/sliding panel*).
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!

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
others.
