D
FLOOR: This setting sends most of the air through
the ducts near the floor. The rest comes out of the
defroster and side window vents. When in this
setting and the RECIRC setting, the windows can
fog up. See "RECIRC" in the Index.
FRONT: This setting brings in outside air and
directs most of the air through the defrost vent. Some of
the air also goes to the floor ducts and the side window
defogger outlets. The indicator on the button will light
and WINDSHIELD will be lit in the display. The air
conditioning compressor will run automatically in this
setting unless the outside temperature is below
_ _
40 F (4 C).
VENT: This pushbutton turns the air conditioning
compressor on and off. The indicator is lit when the
compressor is turned off. Recirculation is not permitted
when the compressor is off. The system will try to
control the temperature automatically, but without
the compressor.
VENT is not permitted in FRONT defrost mode. If the
VENT button is pushed while in FRONT defrost mode,
the indicator will light for one second and then turn off.
RECIRC: This setting recirculates much of the air
inside your vehicle. This setting is not permitted in
FRONT defrost mode and is only permitted in
WINDSHIELD/FLOOR mode if the compressor
is turned on. The indicator light will be lit when
recirculation is engaged, but will light for one second
and then turn off if selected when not permitted.
Operating the climate control system in the RECIRC
mode may cause fogging of the vehicles windows when
the weather is cold and damp. To clear the fog, switch
the system to either WINDSHIELD/FLOOR or
WINDSHIELD mode and increase the fan speed.
-
To avoid re fogging of the windows, operate the
system with RECIRC disengaged.
