to the windshield and the side window outlets, with
some air directed to the floor outlets. In this mode, the
system will automatically turn off recirculation and
run the air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation
cannot be selected while in the defrost mode.

Outlet Adjustment

The air outlets are located in the center and on the
sides of your instrument panel. See Instrument Panel
Overview on page 3-4. You can move the vents to direct
the flow of air or close the outlets altogether. When
you close a vent, it will increase the flow of air coming
out of any vents that are open.
Keep the path under the front seats clear of objects to
help circulate the air inside of your vehicle more
effectively.
