Back up battery MERCEDES-BENZ S350 2006 W221 Owner's Manual

201 Controls in detail
Automatic climate control
The system automatically switches 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 ± 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 buttonF (
page 193).
The indicator lamp on the button
comes on.
Deactivating

Press buttonF (
page 193) again.
The indicator lamp on the button goes
out.
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 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.
