—If
quick circulation of cooled air is de-
sired, select this mode.
2OUTSIDE AIR mode — The system
will take fresh outside air into the ve-
hicle.

heating, the windows will fog up more easi-
ly.
In the following cases, the RECIRCU-
LATED mode may change to the OUT-
SIDE AIR mode automatically to prevent
interior fog.
DWhen the outside temperature be-
comes lower than 5 _C (41 _F).
