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 air flow volume, and 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 right mode knob to AUTO, and place the blower
control (left knob) to either LO AUTO or HI AUTO. The LO
AUTO position should be used for front seat occupantsonly. The HI AUTO position should be used when more air
flow is desired, or when rear seat occupants are present.
Dial in the temperature 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 automatically using the heating system.
Should the desired 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.
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.
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.

the rear window defroster is ON. The defroster automati-
cally turns off after approximately 10 minutes of opera-
tion for the first push of the button, and will turn off after
approximately 5 minutes for the second push of the
button.
CAUTION!
To avoid damaging the electrical conductors of the
rear window defroster, do not use scrapers, sharp
instruments, or abrasive window cleaners on the
interior surface of the window.
Labels can be peeled off after soaking with warm
water.
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. The button includes an
LED that 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“Recirculate”icon button to return to
outside air. Some temp./humidity conditions will cause
captured interior air to condense on windows and ham-
per visibility. For this reason, the system will not allow
“Recirculate”to be selected while in the defrost or
defrost/floor modes. Attempting to use the recirculation
while in these modes will cause the LED in the button to
blink and then turn off.
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 section 7, Maintenance Procedures, 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.
NOTE:See Operating Tips chart (for Manual A/C
Control) at the end of this section for suggested control
settings in different weather conditions.
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
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—If Equipped
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to“Maintenance Procedures”in
your Owner’s Manual for filter replacement instructions.

at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.
NOTE:
•
The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1–3 miles (1.6–4.8 km) of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into“Overdrive”when cold. This is
considered a normal condition. Pulling the shift lever
into the“3”position will show that the transmission is
able to shift into and out of“Overdrive.”
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and will not cause damage to thetransmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. Park (P), Reverse (R), and Neutral (N) will
continue to operate. This Reset feature allows the vehicle
to be driven to a dealer for service without damaging the
transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into PARK (P).
•Turn the key to LOCK then start the engine.
•Shift into“D”and resume driving.
202 STARTING AND OPERATING
Neutral
No power is transmitted from the engine to the drive
axle. When the brakes are released, the vehicle can be
moved freely (pushed or towed). Do not engage in
NEUTRAL position while driving except to coast when
the vehicle is in danger of skidding (e.g., on icy roads).
The engine may be started in this range. Use this range
for starting your vehicle if it is moving or being towed.
CAUTION!
Coasting the vehicle, or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage.
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 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 AutoStick mode and select the“3”range.
AutoStickGear selection
The transmission gear can be selected by pressing the
selector lever to the right or the left with the selector lever
in the DRIVE position. The gear currently selected is
indicated in the instrument cluster display. Briefly press
selector lever in the“D-”direction. The transmission will
shift from the current gear to the next lower gear. Shifting
into another gear that allows for quicker acceleration or
to slow the vehicle down is possible. Downshifts can also
be performed.
Press and hold the selector lever in the“D-”direction.
The transmission will shift from the current gear directly
to the best gear for acceleration.
STARTING AND OPERATING 205

NOTE:To avoid overrevving the engine when the
selector lever is moved in“D-”direction, the transmis-
sion will not shift to a lower gear if the engine’s revolu-
tions per minute limit would be exceeded.
Briefly press the selector lever in the“D+”direction. The
transmission will shift from the current gear to the next
higher gear.
Press and hold the selector lever in the“D+”direction.
The transmission will shift from the current gear directly
to gear“D”.
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 de-
layed 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, PARK
(P), REVERSE (R), and NEUTRAL (N) will continue to
operate. SECOND gear will operate in the DRIVE (D)
shifter position. The Malfunction Indicator Light may be
illuminated.
206 STARTING AND OPERATING
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 PARK position.
3. Turn off the engine.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move the shift 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“Tem-
porary Transmission Limp Home Mode”in this section.
In Permanent Limp Home Mode, PARK (P), REVERSE
(R) and NEUTRAL (N) will continue to operate. SEC-
OND gear will operate in the DRIVE (D) shifter position.
The malfunction indicator light may illuminate.

the shift lever to the Right or Left (D+/D-) position while
in DRIVE. The transmission will remain in the current
gear until an upshift or downshift is chosen.
Autostick—5.7L Engines
Autostick is a driver-interactive transmission that offers
manual gear shifting capability to provide the driver
with more control. Autostick allows the driver to increase
engine braking ability, eliminate undesirable upshifts
and downshifts, and improve overall vehicle perfor-
mance. This system can also provide the driver with
more control during passing, city driving, mountain
driving, trailer towing, and many other situations.
Autostick Operation
By placing the shift lever in the DRIVE position the lever
can be moved from side to side. This allows the driver to
select a specific gear. Move the shift lever to the Left (-) to
trigger a downshift and to the Right (+) to trigger an
upshift. The gear position will be shown in the transmis-
sion gear display located in the instrument cluster.
NOTE:In the autostick mode the transmission will only
shift up and down when Left or Right (D-/D+) is
manually selected by the driver.Shifting into or out of the autostick mode can be done at
any time without taking your foot off the accelerator
pedal. When the driver wishes to engage autostick,
simply move the shift lever to the Left or Right (D-/D+)
position while in DRIVE.
Hold the shift lever to the right for at least one second to
disengage autostick. The transmission will now operate
automatically; shifting between the five available gears.
•You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
•The transmission will automatically downshift to first
gear when coming to a stop.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when autostick is engaged.
•The transmission will automatically shift up when
maximum engine speed is reached while autostick is
engaged.
