(Recirculate): Press this button to limit the
amount of outside air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. Recirculate is helpful when you are trying to
cool the air quickly or trying to limit odors and dust
from entering the vehicle. When in the AUTO mode,
the system automatically selects recirculate to cool the
vehicle’s temperature. By pressing this button, the
system will lock into the recirculated air mode.
Any adjustment to the air intake must then be made
manually. Recirculation is not available when using the
defrost or defog mode because outside air is needed to
reduce moisture inside of the vehicle.
Operating the system in the recirculation mode may
cause fogging of the vehicle’s windows when the
weather is cold and damp. To clear the fog, switch the
system to either the defog or defrost mode and increase
the fan speed. To avoid re
-
fogging of the windows,
operate the system in the outside air mode.
FRONT: Press the FRONT defrost button to
quickly remove fog or frost from the windshield.
This setting directs most of the airflow to the windshield
and a small amount toward the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode and the air intake mode will be
in outside air.
If the system is in front defrost when you shut the
engine off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost and
the air intake mode will be in outside air.
See “Rear Window Defogger” later in this section for
more information.
