Recirculation Mode (Panel or Bi-Level)
Select either the Panel or Bi-Level
mode positions when the outside air
contains smoke, odors, high humidity,
or if rapid cooling of the interior is
desired. This feature allows for recir-
culation of interior air only, when ei-
ther of these positions are selected. Air
flows through the panel outlets or panel and floor outlets
in these modes.
Panel
Outside air flows through the outlets located in the
instrument panel. These outlets can be adjusted to
direct the airflow.
Bi-Level
Air flows through the outlets located in the instru-
ment panel and those located on the floor.NOTE:There is a difference in temperature between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Heat (Floor)
Outside air flows primarily through the floor out-
lets located under the instrument panel. A small
amount of air is directed through the defrost and side
window demister outlets.
Mix
Outside air flows in equal proportions through the
floor and defroster outlet.
Defrost
Outside air is primarily directed to the windshield
through the defroster outlet located at the base of
the windshield and side window demist outlets.

engine speed or power may be noticed when the com-
pressor cycles. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Recirculate Button
Press this button to recirculate the air inside the
vehicle. Outside air is prevented from entering
the vehicle. Use this mode to temporarily block
out any outside odors, smoke, dust or when
rapid cooling of the interior is required.
Manual control of recirculation is possible only in Panel,
Floor, and Bi-Level modes. It will not operate in Mix, or
Defrost modes. The recirculation symbol will flash three
times indicating recirculation is not available in these
modes.NOTE:If the interior of the windows begin to fog, press
the Recirculate button to return to outside air. Some
conditions will cause captured interior air to fog win-
dows when in recirculate mode.

Air flows through the outlets located in the instru-
ment panel. These outlets can be adjusted to direct
the airflow.
Floor (Heat)
Air flows primarily through the floor outlets lo-
cated under the instrument panel. A small amount
of air is directed through the defrost and side window
demister outlets.

Bi-Level
Air flows through the outlets located in the instru-
ment panel and those located on the floor.
NOTE:There is a difference in temperature between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Defrost
Outside air is directed to the windshield through
the defroster outlet located at the base of the
windshield and side window demist outlets.
NOTE:The air conditioning compressor operates in

Headliner air comes from the outlets in the headliner.
Each of these outlets can be individually adjusted to
direct the flow of air. Moving the air vane knobs on the
outlets to one side will shut off the airflow.
The rear compartment control uses two rotary knobs: one
for the temperature control and the other for the fan
speed control. The mode for the rear air conditioning andheating system is always controlled by the front control
unit. Fan and temperature can be controlled from the
front control unit or the rear control unit.
Rear Rotary Blower Control

Operating Tips
Fast Cooldown
For a fast cooldown, set the blower fan to the highest
setting, set the mode control to the panel fresh position,
press the Snowflake button to turn on the air condition-
ing, and drive with the windows open for the first few
minutes. Once the hot air has been expelled, close the
windows and set the mode selector to the Recirculation
panel or Recirculation Bi-level position. When a comfort-
able condition has been reached, choose a mode positionand adjust the temperature control and blower speed as
necessary to maintain comfort. For high humidity condi-
tions, it may be necessary to remain in the Recirculation
mode to maintain comfort.
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases,
turning on the air conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using Mix Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Interior fogging
on the windshield can be quickly removed by selecting
the defrost mode.

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminants (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminants increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions. This will also prevent snow ingestion into the
ducts.
