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 blower control rotary knob (on the
left) controls the blower and can be set
in one of four speeds and OFF.The
blower fan motor will remain on un-
til the system is turned to the OFF
position or the ignition is turned
OFF.
NOTE:For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the “O” (Off)
position.
Temperature Control
The temperature control rotary knob
(in the center) controls the air tem-
perature. The coldest temperature set-
ting is on the extreme left and the
warmest setting on the extreme right
of the rotation. The knob can be posi-
tioned at any point on the dial.
Mode Control
The mode control rotary knob (on the
right) can be placed in several posi-
tions. Dots between each of the mode
selections identify intermediate modes
that allow the occupants to fine tune
airflow distribution.

Defrost
Air is directed to the windshield through the
outlets at the base of the windshield. Air is also
directed to the front door windows through the side
window demister grilles. Some airflow is delivered to the
floor while in defrost so that comfort can be maintained.
Defrost/Floor
Air flows through the front and rear floor outlets
and the outlets at the base of the windshield. Air is
also directed to the front door windows through the
side window demister grilles. Some airflow is delivered
to the floor while in defrost so that comfort can be
maintained.
Floor
Air flows through the floor outlets located under
the instrument panel and into the rear seating areathrough vents under the front seats. Some airflow is
delivered to defrost while in the floor mode so that
comfort can be maintained.
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 tempo-
rarily block out outside odors, smoke, and dust.
Air Conditioning
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 airflow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
274 UNDERSTANDING YOUR INSTRUMENT PANEL

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.
Turn the mode control (on the right) knob to AUTO, and
place the blower control (on the left) to either LO AUTO
or HI AUTO. The LO AUTO position should be used forfront seat occupants only. The HI AUTO position should
be used when more airflow 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 automati-
cally using the heating system. Should the desired com-
fort level require air conditioning, the system will auto-
matically make the adjustment.
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 air
temperature 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.

Air Conditioning
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.
Recirculation
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 condi-
tions such as smoke, odors, dust, or high humidity are
present. This will cause the LED to illuminate.NOTE:
•The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor’s location.
Mud on the windshield may also cause poor operation
of this system.
•To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
•Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
276 UNDERSTANDING YOUR INSTRUMENT PANEL

•Most of the time, when in Automatic operation, you
can temporarily put the system into Recirculation
mode by pressing the “Recirculation” button. How-
ever, under certain conditions in automatic the system
is blowing air out of the defrost vents. When these
conditions are present, and the “Recirculation” button
is pressed, the indicator will flash and remain off. This
tells you that you are unable to go into Recirculation
mode at this time. If you would like to go to Recircu-
lation mode, you must first move your mode knob to
Panel, Panel/Floor, or Floor, then press the “Recircu-
lation” button. This feature will reduce the possibility
of window fogging.Manual Operation
This system offers a full complement of manual override
features which consist of Blower Preferred Automatic,
Mode Preferred Automatic with Manual Air Temperature
Control, and Manual. This means the customer can
override the blower, mode, and disable Automatic Tem-
perature Control completely.
NOTE:Please read the Automatic Temperature Control
Operation Chart below for details.
