²When shifting into P (Park), depress the button on the
shift lever and firmly move the lever all the way
forward until it stops.
²Look at the shift indicator window on the console to
ensure it is in the P (Park) position.
²When 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 steering
wheel and shift lever are released. Otherwise, dam-
age to steering column or shifter could result.
RÐReverse
Use this range only after the vehicle has come to a
complete stop.
NÐNeutral
Shift to N (Neutral) when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
Overdrive
For most city and highway driving. The transmis-
sion contains electronically controlled 4th and 5th
gears (Overdrives) and will automatically shift from D
(Drive) to 4th and 5th gears if the following conditions
are present:
²The transmission selector is in D (Drive).
²The O/D OFF switch has not been activated.
182 STARTING AND OPERATING

²Vehicle speed is above approximately 30 mph (48
km/h).
²Transmission 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.
4th and 5th gears (Overdrive) can be locked out by
pressing the O/D OFF switch located on side of the
gearshift lever. The O/D OFF indicator light will illumi-
nate to show that the switch has been activated. When
the light is on, 4th and 5th gears (Overdrive) are 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.The O/D OFF feature must be selected, if desired, each
time the engine is started.
NOTE:If the vehicle is started in cold outside tempera-
tures, shifts into Overdrive may be delayed (4.7L engines
only). Normal Overdrive and shifting operation will
resume when the temperature of the transmission

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 in the instrument
panel, alerts the driver that a four wheel drive mode
which locks the front and rear driveshafts together has
been selected. This light illuminates when the transfer
case is shifted to either the 4 PART TIME or 4LO
positions. There is no light for the 2WD, 4 FULL TIME, or
N (Neutral) positions.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The Selec-Tracttrans-
fer case is not equipped with a synchronizer and there-
fore the front and rear driveshaft speeds must be equal
for the shift to take place. Shifting while only the front or
rear wheels are spinning can cause damage to the trans-
fer case.
When operating your vehicle in 4LO, the engine speed is
approximately three times that of the 4 ALL TIME
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).

Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts 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.

2WD
Rear Wheel Drive High Range Ð Normal street and
highway driving. Dry hard surfaced roads.
4 PART TIME
Part Time 4 Wheel Drive High Range Ð 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 Ð Employs inter-
axle differential. Allows front and rear wheels to rotate at
different speeds. All roads surfaces.

N (Neutral)
Neutral Ð Disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. Refer to ªRecreational Towingº in Sec-
tion 5 of this manual.
4LO
Part Time Four Wheel Drive Low Range Ð Low speed 4
wheel drive. Locks the transfer case inter-axle differen-
tial. 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).
Shifting Procedure
2WD to 4 PART TIME or 4 PART TIME to 2WD
Shifting between 2WD and 4 PART TIME can be made
with the vehicle stopped or in motion. If the vehicle is in
motion, shifts can be made up to 55 mph (88 km/h). With
the vehicle in motion, two momentary releases of the
accelerator pedal may be required after shifting. This will

with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h).
Quadra-Trac IITOperating
Instructions/Precautions Ð If Equipped
The Quadra-Trac IIttransfer case is fully automatic in the
normal driving 4 ALL TIME mode. The Quadra-Trac IIt
transfer case provides three mode positions Ð four wheel
drive high range, neutral, and four wheel drive low
range.
This transfer case is fully automatic in the 4 ALL TIME
mode. The 4 ALL TIME mode transmits torque to the rear
axle during normal driving, similar to a rear wheel drive
vehicle. When speed difference is increased between the
front and rear driveshafts the majority of engine torque
can be transmitted to the front driveshaft.
When additional traction is required, the 4LO position
can be used to lock the front and rear driveshafts togetherand force the front and rear wheels to rotate at the same
speed. The 4LO position is intended for loose, slippery
road surfaces only. Driving in the 4LO position on dry
hard surfaced roads may cause increased tire wear and
damage to driveline components.
When operating your vehicle in 4LO, the engine speed is
approximately three times that of the 4 ALL TIME
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each

NOTE:The instrument cluster ªBrake Warning Lightº
indicates only that the parking brake is applied. It does
not indicate the degree of brake application.Before leaving the vehicle parked on a hill, you must
make sure the parking brake is fully applied and place
the gear selector in the P (Park) position. Make certain the
transfer case is in gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of P (Park).
The parking brake should always be applied when the
driver is not in the vehicle.
