if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases beyond a
predetermined level, for example in
a tunnel.
Please note that the charcoal filter
must be activated (
page 164) for the
air recirculation mode to be activated

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.

m o d e i s s e l e c t e d o r i f
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 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.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!If theAC
OFF
button on the automatic
climate control panel starts to blink,
this indicates that the air conditioning
is losing refrigerant. The compressor
has turned itself off. The air condition-
ing cannot be turned on again.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.
