Activated charcoal filter
An activated charcoal filter markedly reduces bad odors
and removes pollutants from air entering the passenger
compartment.
To select, press e button. The indicator lamp in the
button illuminates.
To cancel, press e button. The indicator lamp in the
button goes out.
The system switches automatically to the air
recirculation mode, if the carbon monoxide (CO) or
nitrogen oxides (NO
X
) concentration of the outside air
increases beyond a predetermined level.
The automatic air recirculation mode does not function
if economy mode
S is selected or if the outside
temperature has fallen below 40
°
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.
