NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in
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.
Front Blower Control
The front blower controls the amount
of air delivered to the passenger com-
partment. There are four blower
speeds. The fan speed increases as you
turn the control clockwise. When the
front blower control is turned to OFF,
the blower will be turned off and the
system will be positioned in recirculation mode.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.
Front Mode Control
The mode control allows you to
choose from several patterns of air
distribution.
NOTE:To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots and give an even blend of both
modes.
270 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes, even if
the A/C button has not been pressed. This dehumidifies
the air to help dry the windshield.
Temperature Control
The temperature of the air is controlled by a slide located
on the top center of the control panel. Move the slide left
or right to change the temperature. The blue area of the
scale indicates cooler temperatures while the red area
indicates warmer temperatures.
Rear Temperature Control — If Equipped
Rotating this knob left to the REAR
CONTROL position allows the pas-
sengers in the second and third row
seats to control the blower speed and
temperature by means of the rear con-
trol located in the rear of the center

Automatic Control
The ATC system can maintain a steady comfort level in
various weather conditions with a simple operation:
•Select your desired temperature setting by pressing
the + or - side of the Temp rocker switches. A digital
temperature setting for driver and passenger will be
displayed. The ATC system uses an infrared sensor
located in the overhead console to measure the tem-
perature of the driver and passengers. Based on the
sensor input, the system will automatically control
comfort by varying the temperature, fan speed, and
mode. This maintains a comfortable temperature, even
under changing conditions. It is important that objects
are not blocking the infrared sensor. It is also impor-
tant that objects are not used that may scratch or
damage it in any way.
Level Of Automatic Control
72°F (22°C) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:
•The temperature setting can be adjusted at any time
without affecting automatic control operation. It is not
necessary to move the temperature setting for cold or
hot vehicles. The system automatically adjusts the
temperature, mode and fan speed to provide comfort
as quickly as possible.
•In cold weather, the fan will not turn on in Auto mode
until the engine coolant has warmed up sufficiently.
This is indicated by the “WARM UP DELAY” message
on the display.
•The temperature can be displayed in U.S. or Metric by
selecting the U.S./METRIC Customer-Programmable

feature. Refer toOverhead Console Customer-
Programmable Featuresin Section 3. The mode will
also be shown in the display and will change as
required during automatic operation.
•The system can be put into recirculate mode without
affecting ATC operation. This will prevent outside air
from entering the vehicle. Use this mode to tempo-
rarily block out any outside odors, smoke, or dust.
Manual Control (ATC)
You may also choose to customize your comfort by
selecting the fan speed and mode manually. Turning the
fan speed knob or any mode button places the system
into manual operation.
While in manual operation there are six fan speeds
available and the choice of any mode. The airflow
temperature is adjusted automatically to maintain the
desired comfort level. You can adjust the temperature by
pressing the + or - Temp rocker switches.
FAN Control
Use this knob to regulate the amount of air delivered
through the system in any mode you select. Rotation
of the knob to increase (clockwise) or decrease (counter-
clockwise) fan speed.
Air Conditioning Operation
Press this button to enable the air conditioning
system. Compressor operation is automatic when
you press the AUTO button and no snowflake is
shown. A snowflake indicates that the A/C system is
enabled. The snowflake will not be displayed in AUTO
mode even though the A/C system is enabled.
The compressor may operate at any temperature above
32°F (0°C).
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in

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.
Panel
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.
Mix
Outside air flows in equal proportions through the
floor and defroster outlets.
276 UNDERSTANDING YOUR INSTRUMENT PANEL

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
both Mix and Defrost or a blend of these modes, even if
the A/C snowflake button has not been pressed. This
dehumidifies the air to help dry the windshield.
Rear Temperature Control (ATC)
