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 ± 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.

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 flashing, 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.

neath the vehicle. This is normal and
not an indication of a malfunction.
!If the± button on the automatic cli-
mate control panel starts to flash, this
indicates that the air conditioning is
losing refrigerant. The compressor has
turned itself off. The air conditioning
