RecirculationThe 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 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 (ATC) — If
Equipped
The Automatic Temperature Control (ATC) system auto-
matically maintains the interior comfort level desired by
the driver and passenger.
226 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 for
front 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.
Automatic Temperature Controls (ATC)

UNDERSTANDING YOUR INSTRUMENT PANEL 227

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 conditions 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.
•Most of the time, when in Automatic operation, you
can temporarily put the system into Recirculation
mode by pressing the Recirculation button. However,
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 Recirculationmode 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 Recircula-
tion 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.
