Automatic Temperature Control (ATC) Ð If
Equipped
The control can be turned on by pressing the POWER
button. When the control is turned on, it will be in the last
mode prior to being turned off. Pressing the POWER
button again will turn off the control. The control can also
be turned on by pressing any button and it will display
the corresponding operating mode for that button.
Automatic Control
The ATC system can maintain a steady comfort level in
various weather conditions with a simple operation:
²Select your desired temperature setting by pressing
the + or ± side of the TEMP rocker switch.
184 INSTRUMENT PANEL AND CONTROLS

The ATC system uses an infrared sensor located in the
overhead console to measure the temperature of the
driver. Based on the sensor input, the system will auto-
matically control comfort by varying the temperature, fan
speed, and mode. This maintains a comfortable tempera-
ture, even under changing conditions. It is important that
the infrared sensor is kept clean and that objects are not
blocking the sensor. It is also important that objects are
not used that may scratch or damage it in any way.
Level Of Automatic Control
72ÉF (22ÉC) 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 tem-
perature, mode and fan speed to provide comfort as
quickly as possible.NOTE: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.
NOTE:The temperature can be displayed in U.S. or
Metric by selecting the US/M customer programmable
feature. Refer to the9Overhead Console-Customer Pro-
grammable Features.9The mode will also be shown in the
display and will change as required during automatic
operation.
NOTE:The system can be put into recirculate mode
without affecting ATC operation. This will prevent out-
side air from entering the vehicle. Use this mode to
temporarily block out any outside odors, smoke, or dust.

Manual Control (ATC)
You also may choose to customize your comfort by
selecting the fan speed and mode manually. Pressing the
fan speed button 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 switch.
FAN Control
Use this button to regulate the amount of air deliv-
ered through the system in any mode you select.
Press the + or ± side of the button to increase or decrease
fan speed.
Air Conditioning Operation
Press this button to turn on the air conditioning
compressor. A snow flake symbol in the displayshows that the compressor is on. Compressor operation is
automatic when you press the AUTO button and no
snowflake is shown.
The compressor can operate at any temperature above
32ÉF (0ÉC).
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 is on. 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.
186 INSTRUMENT PANEL AND CONTROLS

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
Outside air flows through the outlets located in the
instrument panel. These outlets can be adjusted to
direct the airflow.
Floor (Heat)
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 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 primarily directed to the windshield
through the defroster outlets 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

Rear Zone Climate Control Ð If Equipped
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 and
heating 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.

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 Recirculationpanel or Recirculation Bi-level position. When a comfort-
able condition has been reached, choose a mode position
and 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 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.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.
When stopped in heavy traffic, it may be necessary to
shift into NEUTRAL and press the accelerator slightly for
fast idle operation.
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.

check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap±if equipped. This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
ªcold tire inflation pressureº. Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least 3 hours, or driven less than 1mile
(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire side wall.Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12É F (7É C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage especially in
the winter.
Example: If garage temperature = 68É F (20É C) and the
outside temperature = 32É F (0É C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12É F (7É C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
