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.
iThe air recirculation mode is deactivat-
ed automatically:

after 5 minutes if the outside
temperature is below
approximately 41°F (5°C)


after 5 minutes if the air condition-
ing is turned off


after 30 minutes if the outside
temperature is above
approximately 41°F (5°C)
iPress and hold button, for approx.
2 seconds. The side windows and or
tilt/sliding sunroof* will return to their
previous position. You can release
button, once the opening proce-
dure has begun. The windows and

position.
A window or tilt/sliding sunroof* will
only return to its previous position if it
has not been moved to another posi-
tion using the respective window
switch or tilt/sliding sunroof* switch
after it was closed with button,. A
window or tilt/sliding sunroof* that
was moved will remain in its current po-
sition if button, i s u se d to re -open
