Diesel Fuel-Water Separator
A diesel fuel-water separator separates the water nor-
mally found in diesel fuel. A manual hand prime pump is
located on the filter head for re-priming the fuel system.
The fuel-water separator is located on the driver side
cowl in the engine compartment. Refer to “2.8L Turbo
Diesel Engine Compartment” in Section 7 for location. NOTE:
If the “Water-In-Fuel Warning Light” (located in
the instrument cluster) comes on, this indicates that
water has collected in the fuel filter and should be
drained immediately. See your authorized dealer for
service.

WARNING!
When parking your vehicle, always leave a manual
transmission in first gear and apply the parking
brake fully to guard against vehicle movement and
possible injury or damage. Never use any gear as a
substitute for the parking brake.
CAUTION!
To drive as safely as possible and to prolong the life
of your manual transmission, follow these tips:
•Before shifting from a forward gear into reverse, or
from reverse to a forward gear, stop vehicle com-
pletely. Otherwise, accelerated transmission wear may
result.
•Do not operate at sustained high engine or road
speeds in lower gears. Engine damage may result.
•Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
•Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
•When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
•Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
•During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
•Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.

Automatic Transmission
Shifting from D (Drive) to P (Park) or R (Reverse) (or
from P or R to D) should be done only after the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake when moving the
shift lever between these gears.WARNING!
It is dangerous to shift the selector lever out of “P” or
“N” if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
Brake Transmission Shift Interlock System
This vehicle is equipped with a brake transmission shift
interlock system (BTSI), which holds the gearshift lever
in the P (Park) position when the ignition switch is in the
OFF position. To move the gear selector lever out of the
P (Park) position, turn the ignition switch to the ON
position, and press the brake pedal and the button on the
front of the shifter handle.
Automatic Shift Controls
STARTING AND OPERATING 227

The following indicators should be used to ensure that
you have engaged the transmission shift lever into the P
(Park) position:
•When shifting into P (Park), depress the button on the
shift lever and firmly move the lever all the way
forward until it stops.
•Look at the shift indicator window on the console to
ensure it is in the P (Park) position.
•When engaged in P (Park), you will not be able to
move the shifter rearward without depressing the shift
lever button.
CAUTION!
Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK to ON so the
steering wheel and shift lever are released. Other-
wise, damage to the steering column or shifter could
result.
R (Reverse)
For moving the vehicle rearward. Always stop before
moving the lever to R (Reverse), except when rocking the
vehicle.
N (Neutral)
Engine may be started in this position.
NOTE: Towing the vehicle, coasting, or otherwise driv-
ing with the transmission in N (Neutral) can cause severe
damage to the transmission.
STARTING AND OPERATING 229

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
time restores the Overdrive function. The lockout feature
is useful when towing a trailer or carrying a heavy load.
NOTE: If the vehicle is started in cold outside tempera-
tures, shifts into Overdrive may be delayed. Normal
Overdrive and shifting operation will resume when the
temperature of the transmission reaches the appropriate
temperature. Refer to the “Note” under “Torque Con-
verter Clutch” later in this section.
If the transmission temperature gets too hot, the trans-
mission may downshift out of Overdrive or engage
overdrive at higher vehicle speeds until the transmission
cools down. After cooldown, Overdrive will resume
normal operation. 2 (Second)
For moderate grades and to assist braking on dry pave-
ment or in mud and snow. Begins at a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.
1 (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no
upshift. Provides engine compression braking at low
speeds.
STARTING AND OPERATING 231

CAUTION!
•Never press on the accelerator pedal with the
engine running, vehicle in gear, and the brakes
applied. Always apply the brakes when stopped
on a incline. Failure to follow these instructions
can cause overheating and damage to the trans-
mission.
•When “rocking” a stuck vehicle by moving be-
tween “First” and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
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
232 STARTING AND OPERATING

WARNING!
•Because 4-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit.
•You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging
the parking brake. The transfer case Neutral (N)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the
vehicle to move despite the transmission position.
The parking brake should always be applied
when the driver is not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position see the information below:
2H
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.
4H
4-Wheel-Drive High Range - Locks the front and rear
driveshafts together. Forces the front and rear wheels to
rotate at the same speed. Additional traction for loose,
slippery road surfaces only.
N
Neutral - Disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. Refer to “Recreational Towing” in Sec-
tion 5 for more information.
236 STARTING AND OPERATING

4L
4-Wheel-Drive Low Range - Low speed 4 wheel drive.
Locks the front and rear driveshafts together. Forces the
front and rear wheels to rotate at the same speed.
Additional traction and maximum pulling power for
loose, slippery road surfaces only. Do not exceed 25 mph
(40 km/h). (Allows engine starting without depressing
the clutch pedal on vehicles equipped with manual
transmission. Refer to “Starting Procedures — Manual
Transmission (4WD Models Only)” in this section.
Shifting Procedure
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with the
vehicle in motion up to 55 mph (88 km/h). The transfer
case will engage/disengage faster if you momentarily
release the accelerator pedal after completing the shift.
Apply a constant force when shifting the transfer case
lever.
4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission to N (Neutral) or depress the
clutch on a manual transmission. While the vehicle is
coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not pause in
transfer case N (Neutral).
NOTE: To shift from 4H to 4L, the shift lever should
pushed away from the driver, and then rearward into 4L.
In 4H, there is a neutral stop to prevent shifting into N
(Neutral) by accident.
NOTE: Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift automatic
transmission to N (Neutral), hold foot on brake, and turn
engine OFF. Make shift to the desired mode.
STARTING AND OPERATING 237

NOTE:Shifting into or out of 4L is possible with the
vehicle completely stopped, however difficulty may oc-
cur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The pre-
ferred method is with the vehicle rolling 2 to 3 mph (3 to
5 km/h). Avoid attempting to engage or disengage 4L
with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h).
Selec-Trac \bOperating Information/Precautions —
If Equipped
The Selec-Trac transfer case provides 5 mode positions -
normal 2-wheel drive mode, part-time 4-wheel drive
high range, full-time 4-wheel drive high range, neutral,
and 4-wheel drive low range.
This transfer case is equipped with an inter-axle differ-
ential which allows driving the vehicle in the 4 FULL
TIME position at all times on any given road surface 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.
238 STARTING AND OPERATING

Proper operation of 4-wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
can cause damage to the transfer case.
WARNING!
•Because 4-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit.
•You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging
the parking brake. The transfer case Neutral (N)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the
vehicle to move regardless of the transmission
position. The parking brake should always be
applied when the driver is not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position see the information below:
2WD
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.
4 PART TIME
Part Time 4–Wheel Drive High Range - Locks the transfer
case inter-axle differential. Forces the front and rear
wheels to rotate at the same speed. Additional traction
for loose, slippery road surfaces only.
4 FULL TIME
Full Time 4-Wheel Drive High Range - Employs an
inter-axle differential. This allows front and rear wheels
to rotate at different speeds, on all road surfaces.
