Charcoal filter
An activated charcoal filter markedly
reduces bad odors and removes pollutants
from air entering the passenger compart-
ment. The charcoal filter can be activated
or deactivated.
The system switches automatically to the
air recirculation mode, if the
charcoal filter is switched on
carbon monoxide (CO) or nitrogen
oxide (NO
) concentration of the out-
X
side air increases beyond a predeter-
mined level
i
The automatic air recirculation mode does
not function if the A/C (indicator lamp on
button 2 or 9 not lit) mode is deactivat-
ed, or if the outside temperature has fallen
below 41°F (5°C).
Activating
Press button e ( page 201).
The indicator lamp on the button
comes on.
i
If you press and hold button e, the side
windows and tilt/sliding sunroof* will close.
i
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.
Warning!
Never operate the side windows and the
tilt/sliding sunroof* (CLK coupe) if there is
the possibility of anyone being harmed by
the closing procedure.
When using the air recirculation mode with
convenience closing feature, should the up-
ward movement of a window be blocked by
some obstructions including but not limited
to arms, hands, fingers. etc., the automatic
reversal feature will not operate.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by
releasing the e button or by pressing or
pulling the respective window switch.
