NOTE:The air conditioning compressor operates in MIX
and DEFROST, or a blend of these modes even if the A/C
button is not pushed. This dehumidifies the air to help
dry the windshield. To improve fuel economy, use these
modes only when necessary.
Recirculation Control
Push the Recirculation Control button to
choose between outside air intake or recircula-
tion of the air inside the vehicle. A LED will
illuminate when you are in Recirculation
mode. Only use the Recirculation mode to temporarily
block out any outside odors, smoke, or dust, and to cool
the interior rapidly upon initial start-up in very hot or
humid weather. NOTE:
•
If the RECIRCULATION button is pushed when the
system is in Defrost mode, the Recirculation LED
indicator will flash three times and then turn off to
indicate Recirculation mode is not allowed.
• 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.
• In cold or damp weather, the use of the Recirculation
mode will cause windows to fog on the inside because
of moisture buildup inside the vehicle. For maximum
defogging, select the outside air position.
• The A/C can be deselected manually without disturb-
ing the mode control selection by pushing the A/C
button.

6. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
and demist outlets. The Mode settings are as follows:•Panel Mode
Air comes from the outlets in the instrument
panel. Each of these outlets can be individu-
ally 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.
• Bi-Level Mode
Air comes from the instrument panel outlets
and floor outlets. A slight amount of air is
directed through the defrost and side window
demister outlets. NOTE:
BI-LEVEL mode is designed under comfort con-
ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.
•Floor Mode
Air comes from the floor outlets. A slight
amount of air is directed through the defrost
and side window demister outlets.
• Mix Mode
Air comes from the floor, defrost and side
window demister outlets. This mode works
best in cold or snowy conditions.
NOTE: The air conditioning compressor operates in MIX
and DEFROST modes even if the A/C button is not
pressed. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, utilize these modes
only when required.
