Automatic Temperature Control Ð If Equipped
Automatic Operation
The Infrared Dual-Zone Climate Control System auto-
matically maintains the climate in the cabin of the vehicle
at the comfort levels desired by the driver and passenger.
To accomplish this, the system gathers information from
the controls on the climate control, from a dual sun-
sensor located in the top of the instrument panel, from aninfrared sensor located in the face of the climate control,
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. The dual sun-sensor monitors sun
load coming through the windshield. The infrared sensor
independently measures the surface temperature of the
driver and passenger. Other sensors take account of
vehicle-speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple. Begin by turning
the Mode Control knob (on the right) to AUTO, and place
the Blower Control knob (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. Then, dial in the temperature you
would like the system to maintain by rotating the driver

or passenger Temperature Control knob. Once the com-
fort level is selected, the system will maintain that level
automatically using the heating system. Should the de-
sired 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 and closes the outside air intake.
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 operation.
Air conditioning in this system is automatic.
Pressing the Air Conditioning Control button
while in AUTO mode will cause the LED in the
control button to flash three times and then turn off.
This indicates that the system is in AUTO mode and
requesting the air conditioning is not necessary.The system will automatically control recir-
culation. However, pressing the Recircula-
tion Control button will temporarily put the
system in recirculation mode (ten minutes).
This can be used when outside conditions such as
smoke, odors, dust, or high humidity are present.
Activating recirculation will cause the LED in the
control button to illuminate. After ten minutes, the
system will return to normal AUTO mode function
and the LED will turn off.
NOTE:
²
The surface of the climate control panel and the top
center of the instrument panel should be kept free of
debris due to the location of the climate control
sensors. Mud on the windshield may also cause poor
operation of this system.
²Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the Recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper
visibility. For this reason, the system will not allow

The operator can override the AUTO mode setting to
change airflow distribution by rotating the Mode Control
knob (on the right) to one of the following positions.
²Defrost
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.
²
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.
²
Floor
Air flows through the floor outlets located
under the instrument panel and into the rear
seating area through vents under the front seats.²
Bi-Level
Air flows through the outlets located in the
instrument panel and through the outlets lo-
cated on the floor. 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.
²

Air Conditioning Control
Press this button to turn on the air condition-
ing during manual operation only. When the
air conditioning is turned on, cool dehumidi-
fied air will flow through the outlets selected with
the Mode control dial. Press this button a second
time to turn off the air conditioning. An LED in the
button illuminates when manual compressor opera-
tion is selected.

NOTE:To control the air conditioning manually, the
mode selector must be moved out of the AUTO position.
²Recirculation Control
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. An LED in the button
illuminates when the recirculation 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 Recirculation button to return to outside
air. Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper visibil-
ity. For this reason, the system will not allow Recircula-
tion to be selected while in defrost or defrost/floor mode.
Attempting to use the recirculation while in these modes
will cause the LED in the control button to blink and then
turn off.
Operating Tips
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to ªMaintenance Proceduresº in Section 7 of this manual
for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
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
182 UNDERSTANDING YOUR INSTRUMENT PANEL

system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter Ð If Equipped
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to ªMaintenance Proceduresº in
Section 7 of this manual for filter replacement instruc-
tions.

CAUTION!
Coasting the vehicle, or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage.
WARNING!
Do not coast in N (Neutral) and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.
D (Drive)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts and best fuel economy.
The transmission automatically upshifts through fifth
gear. The D (Drive) position provides optimum driving
characteristics under all normal operating conditions.When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers, use the AutoSticktmode and select the ª3º
range.
AutoSticktGear selection
The AutoSticktfeature can be selected by pressing the
selector lever to the right or the left with the lever in the
D (Drive) position. The gear currently selected is indi-
cated in the instrument cluster display. Briefly, press the
selector lever in the ªD -º direction and the transmission
will shift from the current gear to the next lower gear.
Press and hold the selector lever in the ªD-º direction and
the transmission will shift from the current gear directly
to the next lowest gear for best acceleration.
NOTE:To avoid overrevving the engine when the
selector lever is moved in ªD -º direction, the transmis-
sion will not shift to a lower gear if the engine's revolu-
tions per minute (RPM) limit would be exceeded.
198 STARTING AND OPERATING

Briefly, press the selector lever in the ªD +º direction and
the transmission will shift from the current gear to the
next higher gear.
Press and hold the selector lever in the ªD +º direction
and the transmission will shift from the current gear
directly to gear ªD.º
WARNING!
On slippery road surfaces, never downshift in order
to obtain braking action. This could result in drive
wheel slip and reduced vehicle control. Your vehi-
cle's ABS will not prevent this type of loss of control.
You could lose control of your vehicle and have an
accident.
Delayed Shifts in Cold Temperatures
During cold temperature operation, you may notice
delayed upshifts depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency.
Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens, or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped, P (Park),
R (Reverse), and N (Neutral) will continue to operate.
Second gear will operate in the D (Drive) shifter position.
The Malfunction Indicator Light may be illuminated.
A reset feature is available to allow the vehicle to be
driven to a dealer for service. To reset the transmission,
use the following procedure:
1. Stop the vehicle.
2. Move the selector lever to the P (Park) position.
3. Turn off the engine.
4. Wait approximately 10 seconds.
5. Restart the engine.

6. Move the selector lever to the desired range. If the
problem is no longer detected, the transmission will
return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
Have the transmission checked at your authorized dealer
as soon as possible.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
Permanent Transmission Limp Home Mode
Permanent Limp Home Mode will be activated if the
transmission enters temporary Limp Home Mode three
times. Follow the reset procedure described under ªTem-
porary Transmission Limp Home Modeº in this section.
In Permanent Limp Home Mode, P (Park), R (Reverse),
and N (Neutral) will continue to operate. Second gear
will operate in the D (Drive) shifter position. The mal-
function indicator light may illuminate.
AUTOSTICKT
Autosticktis a driver-interactive transmission that offers
manual gear shifting to provide you with more control of
the vehicle. Autosticktallows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
AutostickTOperation
By placing the selector lever in the D (Drive) position, it
can be moved from side to side. This allows the driver to
select a higher or lower range of gears. Moving the
selector lever to the Left (-) triggers a downshift and to
the Right (+) an upshift. The gear position will display in
the instrument cluster on the transmission range indica-
tor.
NOTE:
²
In Autosticktmode, the transmission will only shift
up and down when the driver manually moves the
selector lever Right (D+) or Left (D-).
