CLIMATE CONTROLS
Manual Air Conditioning and Heating System — If
Equipped
The controls for the heating/air conditioning and venti-
lation system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.The instrument panel features four dual-vane airflow
registers. Two registers are located on the outer ends of
the instrument panel and two are located in the center of
the instrument panel. These registers can be closed to
partially block airflow, and they can be adjusted to direct
airflow where the occupant desires.
Blower Control
The rotary knob on the left controls the
blower and can be set in one of four
speeds and OFF.The blower fan mo-
tor will remain on until the system is
turned to the OFF position or the
ignition is turned OFF.

Bi-Level
Air flows both through the outlets located in the
instrument panel and those located on the floor. Air
flows through the registers in the back of the center
console, and under the front seats to the rear seat
passengers. These registers can be closed to partially
block airflow. The center console outlets deliver condi-
tioned air while the floor outlets deliver heated air.
Panel
Air flows through the outlets located in the instru-
ment panel. Air flows through the registers in the
back of the center console to the rear seat passengers.
These registers can be closed to block airflow.Recirculation
The recirculation feature can be selected with
the mode control knob. You may choose be-
tween Bi-Level Recirculation and Panel Recir-
culation air outlets while in this mode. Nor-
mally, air enters from outside the vehicle. However, when
in Recirculation mode air inside the vehicle is re-used.
Use this mode to rapidly cool the inside of the vehicle.
The Recirculation mode can also be used to temporarily
block out outside odors, smoke, and dust.
Air Conditioning Operation
To turn on the Air Conditioning, set the fan control
at any speed and press the snowflake button
located on the control panel. Conditioned air will
be directed through the outlets selected by the mode
control. A light in the snowflake button shows that the air
conditioning is on.

Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
Automatic Temperature Control — If Equipped
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by a dual
sun-sensor in the top of the instrument panel, and an
infrared sensor located in the face of the control unit.
There are also various sensors monitored by this system
which take account for vehicle speed, A/C pressure,
outside temperature, and engine cooling temperature.
The infrared sensor independently measures the surface
temperature of the driver and passenger. Based on the
sensor input, the system automatically adjusts the air
flow temperature, the air flow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.NOTE:The numbers on the temperature dial represent
a comfort setting when the Mode knob is set to Auto, and
not the actual air temperature.
Operation of the system is quite simple. Begin by turning
the right mode knob to AUTO, and place the blower
control (left knob) to either LO AUTO or HI AUTO. The
Automatic Temperature Controls
236 UNDERSTANDING YOUR INSTRUMENT PANEL

LO AUTO position should be used for front seat occu-
pants only. The HI AUTO position should be used when
more air flow is desired, or when rear seat occupants are
present. Dial in the comfort setting you would like the
system to maintain by rotating the driver’s or passenger’s
control knob. Once the comfort level is selected the
system will maintain that level automatically using the
heating system. Should the desired comfort level require
air conditioning, the system will automatically make the
adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation. How-
ever, if the driver and/or passenger temperature knobs
are set to the full hot or full cold positions, the airtemperature out of the ducts will be full hot or full cold
respectively. With the temperature setting in these posi-
tions, the system does not attempt automatic comfort
control.
The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause the LED to flash three times and remain off.
This indicates that the system is in AUTO and requesting
the air conditioning is not necessary.
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in recirculation mode.
This can be used when outside conditions such
as smoke, odors, dust, or high humidity are present. This
will cause the LED to illuminate.

Air flows through the registers in the back of the
center console, and under the front seats to the rear
seat passengers. These registers can be closed to block
airflow. The center console outlets deliver conditioned
air while the floor outlets deliver heated air.
•Panel
Air flows through the outlets located in the in-
strument panel. Air flows through the registers in
the back of the center console to the rear seat passen-
gers. These registers can be closed to block airflow.
Depress this button to turn on and off the air
conditioning during manual operation only. Con-
ditioned outside air is then directed through the
outlets selected on the mode control dial. The button
includes an LED that illuminates when manual operation
is selected.
NOTE:To manually control the air conditioning the
mode selector must be moved out of the AUTO position.This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The recirculation mode should only
be used temporarily. The button includes an
LED that illuminates, which indicates that the recircula-
tion mode is active. You may use this feature separately.
NOTE:Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the “Recirculate” icon button to return to
outside air. Some temp./humidity conditions will cause
captured interior air to condense on windows and ham-
per visibility. For this reason, the system will not allow
“Recirculate” to be selected while in the defrost or
defrost/floor modes. Attempting to use the recirculation
while in these modes will cause the LED in the button to
blink and then turn off.

Rear Temperature Control
The center knob on the Rear Control Panel allows the
third row seat occupants to have control of the rear
temperature as follows:
•When the temperature knob is in the cold (Blue)
position, cold air will be delivered from the outlets. As
the temperature knob is turned towards the hot (Red)
position, the air will get warmer.
Rear Mode Control
•
Floor
Air flows through the floor outlet located on the
right side of the rear floor into the rear seating area.
•Bi-Level
Air flows through both the outlets located in the
rear quarter trim panels, and the one located on
the floor. The rear quarter trim panel outlets can be
closed to block airflow.
•Panel
Air flows through the outlets located in the rear
quarter trim panels. These registers can be closed
to block airflow.
Operating Tips
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. Adjust the temperature
control and blower speed to maintain comfort. Higher
blower speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by selecting the
defrost mode.
244 UNDERSTANDING YOUR INSTRUMENT PANEL

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates 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. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift intoN (Neutral) and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.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.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
