NOTE:
•In Floor, Mix and Defrost modes a small amount of air
will flow through the outboard panel outlets for
occupant comfort.
•The air conditioning compressor operates in Mix,
Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
Recirculation Control Pressing the Recirculation Control button will
put the system in recirculation mode. This can
be used when outside conditions such as
smoke, odors, dust, or high humidity are pres-
ent. Activating recirculation will cause the LED in the
control button to illuminate. NOTE:
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•The use of the Recirculation mode in cold or damp
weather could cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Select
the outside air position for maximum defogging.
•The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.
•The A/C can be deselected manually without disturb-
ing the mode control selection.
•When the ignition switch is turned to the LOCK
position or the ignition switch START/STOP button is
cycled to OFF, the recirculation feature will be
cancelled.

Manual Operation
This system offers a full complement of manual override
features.
NOTE:Each of these features operate independently
from each other. If any one feature is controlled manually,
temperature control will continue to operate automati-
cally.
There are seven fixed blower speeds.
Use the outer dial control to regulate
the amount of air forced through the
system in any mode you select. The
blower speed increases as you move
the control clockwise and decreases
when you move the control counter-
clockwise. The blower fan speed can be set to any fixed speed by
adjusting the blower control outer dial. The fan will now
operate at a fixed speed until additional speeds are
selected. This allows the front occupants to control the
volume of air circulated in the vehicle and cancel the
Auto mode.
The operator can also select the direction of the airflow
by selecting one of the following positions.
Panel Mode
Air comes from the outlets in the instrument panel.
Each of these outlets can be individually adjusted to
direct the flow of air. The air vanes of the center outlets
and outboard outlets can be moved up and down or side
to side to regulate airflow direction. There is a shut off
wheel located below the air vanes to shut off or adjust the
amount of airflow from these outlets.
