Controls in detail
Automatic climate control
The system switches automatically to the
air recirculation mode if the carbon
monoxide (CO) or nitrogen oxide (NO
X
)
concentration of the outside air increases
beyond a predetermined level, for example
in a tunnel.
The automatic air recirculation mode does
not function if AC
OFF
mode is selected or if
the outside temperature has fallen below
41°F (5°C).
The activated charcoal filter should be
switched off when windows fog up on the
inside, or if the passenger compartment
needs to be quickly heated or cooled
down.
Rear window defroster
The rear window defroster uses a large
amount of power. To keep battery drain to
a minimum, switch off the defroster as
soon as the rear window is clear. The de-
froster is automatically deactivated after
approximately 6 to 17 minutes of opera-
tion depending on the outside tempera-
ture.
Activating
̈ Press button F (୴ page 159).
The indicator lamp on the button lights
up.
Deactivating
̈ Press button F (୴ page 159) again.
The indicator lamp on the button goes
out.
i
If you keep button e pressed, the
side windows and the sliding/pop-up
roof will be returned to their previous
positions.
Warning! G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
!
If the rear window defroster switches
off too soon and the indicator lamp
starts blinking, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
