normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
Mode Control
The mode selector (the center rotary knob and the
push-button above it) can be set in any of the following
positions:
OFF
This position turns off the blower motor and outside
air will not pass through any outlets.
Recirculate (Max A/C)
Air flows through the outlets located in the
instrument panel. Allows for circulation of
interior air only which will cool the cabin
faster. This setting can be used in very hot
weather to maximize the effect of the air conditioner. This
mode can also be used to temporarily block out outsideodors, smoke, and dust. Slight airflow from the floor
outlets and the defrost outlets, located at the base of the
windshield, may be noticed.
Panel
Air flows through the outlets located in the instru-
ment panel. Slight airflow from the defrost outlet,
located at the base of the windshield, may be noticed.
Bi-Level
Air flows through the outlets located in the instru-
ment panel, on the floor, and in the rear of the center
console. Slight airflow from the defrost outlet, located at
the base of the windshield, may be noticed.
Floor
Air flows through the floor outlets located under
the instrument panel and through the outlets lo-
cated in the rear of the center console. Slight airflow from

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in N (Neutral) and depress the clutch pedal before
starting vehicle. This vehicle is equipped with a clutch
interlocking ignition system, which requires the clutch to
be fully depressed before starting the vehicle.
4WD Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to depress the clutch
pedal. The 4 LO MODE indicator light will illuminate
when the transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the selector lever in the N (Neutral)
or P (Park) position. Apply the brake before shifting to
any driving range.

MANUAL TRANSMISSION
Clutch Interlocking Ignition System
2WD Models Only — Manual transmission vehicles are
equipped with a clutch interlock safety feature. The
clutch pedal must be fully depressed to allow cranking of
the engine.
4WD Models Only — The exception to this clutch inter-
lock is 4WD models equipped with a manual transmis-
sion. For these models, the clutch interlock feature is
overridden when the vehicle is operated in 4L to enhance
off-road capability. Refer to “Starting Procedures —
Manual Transmission (4WD Models Only)” in this sec-
tion.
6-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the
vehicle, especially on an incline.
Follow the shift pattern on the gearshift knob.
NOTE:The backup lights will come on when your
vehicle is in R (Reverse) gear and the ignition is in the ON
position.
216 STARTING AND OPERATING

•Vehicle speed is above approximately 30 mph (48
km/h).
•Transmission has reached normal operating tempera-
ture.
When frequent transmission shifting occurs while using
Overdrive, such as when operating the vehicle under
heavy load conditions (for example, in hilly terrain,
strong head winds, or trailer towing), turning off over-
drive will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
Overdrive can be locked out by pressing the O/D OFF
button located on side of the gearshift lever. The O/D
OFF indicator light will illuminate to show that the
switch has been activated. When the indicator light is on,
Overdrive is locked out. Pressing the switch a second

Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly
different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the TRANS TEMP warning light in the instru-
ment cluster will come on. After the transmission cools
down, it will return to normal operation.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
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 (TCC) will not engage
until the transmission fluid and engine coolant are
warm (usually after 1–3 miles (1.6–4.8 km) of driving)
and the vehicle speed is above approximately 30 mph
(48 km/h). To understand the difference in operation,
drive the vehicle so that TCC engagement conditions
are correct, and then press and release the “O/D OFF”
button once to disengage the TCC. Wait a few seconds,
and then press and release the “O/D OFF” button
again to engage the TCC. You will notice that the
engine runs at a higher RPM when driving at vehicle
speeds above approximately 30 mph (48 km/h) with
the TCC not engaged. This is a normal condition.
•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 the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
FOUR-WHEEL DRIVE OPERATION
Command-TracOperating
Information/Precautions
The Command-Tractransfer case provides 4 mode
positions-2(rear) wheel drive high range, 4-wheel drive
high range, neutral, and 4-wheel drive low range.
This transfer case is intended to be driven in the 2-wheel
drive position (2H) for normal street and highway con-
ditions such as dry hard surfaced roads.
When additional traction is required the transfer case 4H
and 4L positions can be used to lock the front and rear
driveshafts together and force the front and rear wheels
to rotate at the same speed. This is accomplished bysimply moving the shift lever to these positions. The 4H
and 4L positions are intended for loose, slippery road
surfaces only. Driving in the 4H and 4L positions on dry
hard surfaced roads may cause increased tire wear and
damage to the driveline components.
The PART TIME indicator light, located in the instrument
cluster, illuminates when the transfer case is shifted to the
4H position.
The 4 LO MODE indicator light, located in the instru-
ment cluster, illuminates when the transfer case is shifted
to the 4L position. There is no light for the 2H or N
(Neutral) positions.

including dry hard surfaced roads. The 4 FULL TIME
mode allows the front and rear wheels to rotate at
different speeds which eliminates driveline binding and
component wear that is normally associated with driving
the vehicle in the 4 PART TIME position on dry hard
surfaced roads. This feature provides the safety, security,
and convenience of operating in 4–wheel drive at all
times regardless of road conditions.
When additional traction is required the 4 PART TIME
and 4LO positions can be used to lock the front and rear
driveshafts together through the transfer case inter-axle
differential and force the front and rear driveshafts to
rotate at the same speed. This is accomplished by simply
moving the shift lever to these positions. The 4 PART
TIME and 4LO positions are intended for loose, slippery
road surfaces only. Driving in the 4 PART TIME and 4LO
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to driveline components.The PART TIME indicator light, located on the instru-
ment cluster, illuminates when the transfer case is shifted
to the 4 PART TIME position.
The FULL TIME indicator light, located on the instru-
ment cluster, illuminates when the transfer case is shifted
to the 4 FULL TIME position.
The 4LO MODE indicator light, located on the instru-
ment cluster, illuminates when the transfer case is shifted
to the 4LO position. There is no light for the 2WD, or N
(Neutral) positions.
