[GF08575(FM)05/96]
To gain extra acceleration injOverdrive or
Drive (O/D OFF), push the accelerator to the
floor. The transmission will automatically
downshift to the appropriate gear: third, second
or first.
*
[GF08625(FM)05/96]
Increasing the engine speed above idle without
vehicle movement (such as holding the brake) in
a forward or reverse gear causes transmission
stall.
*
[GF08650(FM)05/96]
NOTE: Continued operation in the stall
condition can result in transmission
overheat, malfunction or fluid
expulsion.

Using the Clutch
*
[GF12300(F )01/96]
Make sure the gearshift lever is in the N
(Neutral) position and your right foot is holding
down the brake pedal. Then press the clutch
pedal to the floor with your left foot. Manual
transmission vehicles have a starter interlock
switch. The starter will not crank until the clutch
pedal is fully depressed. Start the engine and
allow it to idle for a few seconds. Move the
gearshift into 1 (First) or R (Reverse).
*
[GF12400(F )01/96]
To move the vehicle, release the clutch slowly
and at the same time press down slowly on the
accelerator so that the vehicle accelerates.
*
[GF12500(F )01/96]
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to hold
your vehicle at a standstill while waiting on a
hill. These actions will seriously reduce clutch
life.

3. Put the gearshift in Neutral and wait at least
3 seconds before shifting into R (Reverse) to
prevent a grinding noise. Do not release the
clutch.

[GF13500(F )01/96]
4. Push the gearshift all the way to the right
and pull it back into Reverse.
*
[GF13600(F )01/96]
With the 5-speed transmission you can engage R
(Reverse) only by moving the gearshift from the
left of 3 (Third) and 4 (Fourth) gears before you
shift into R (Reverse). This is a special lockout
feature that protects you from accidentally
shifting into R when you downshift from 5
(Fifth) gear.
*
[GF13700(F )01/96]
5. Once R (Reverse) is engaged, slowly release
the clutch pedal from the floor.
*
[GF13800(F )01/96]
If R (Reverse) is not engaged, continue to push
the clutch pedal in while you put the gearshift
back into Neutral. Then, release the clutch pedal
for a moment and repeat steps 2 through 5.

Lever Operated System With Automatic
Locking Hubs

[GF16450(F )01/96]
To shift from 2H to 4H:
[GF16500(F )04/96]
Stop the vehicle and move the transfer case shift
lever straight back to the 4H position, the
automatic locking hubs will engage when the
vehicle is driven. When the automatic locking
hubs are engaged, shifts between 2H and 4H
may take place at any speed.
[GF16550(F )04/96]
q
The automatic locking hubs may disengage in
2H if the vehicle's direction is momentarily
reversed, or the vehicle is allowed to roll
slightly in the opposite direction. If a
grinding noise occurs when shifting from 2H
to 4H while the vehicle is moving, one or
both of the automatic locking hubs have been
disengaged and the transfer case shift lever
should be switched back to the 2H position.
To shift back into 4H, stop the vehicle and
move the transfer case shift lever straight
back to the 4H position.
[GF16600(F )04/96]
q
When the vehicle is stopped while in 4H and
the vehicle's direction is reversed from the
previous direction, the automatic locking hubs
momentarily disengage and then re-engage.
The automatic locking hubs may click as they
automatically engage in the new direction.

To shift from 4H to 2H:
[GF16700(F )04/96]
Move the transfer case shift lever straight
forward to the 2H position. This can be done at
any speed. To disengage the automatic locking
hubs, operate the vehicle in 2H in the opposite
direction for approximately 10 feet (3 meters).
*
[GF16750(F )05/96]
For example:
[GF16800(F )04/96]
If you were driving the vehicle forward in
4H, the automatic locking hubs will
disengage the next time the vehicle is driven
in reverse in 2H for approximately 10 feet (3
meters).
[GF16850(F )04/96]
If you were driving the vehicle in reverse in
4H, the automatic locking hubs will
disengage the next time the vehicle is driven
forward in 2H for approximately 10 feet (3
meters).
[GF16900(F )04/96]
Ð Operating in 2H with the hubs locked
increases fuel consumption, noise, vibration, and
wear. For prolonged 2H operation on dry
pavement, disengage the automatic locking hubs.

[GF16950(F )01/96]
To shift between 4H and 4L:
[GF17000(F )04/96]
Stop the vehicle and place the automatic
transmission into NEUTRAL or depress the
clutch on manual transmission vehicles. Push the
transfer case shift knob down (toward the
ground) and at the same time pull or push the
lever straight forward or rearward (depending
on the desired position, 4H or 4L) in order to
shift the transfer case. This shift should be in
one continuous motion without pausing in the N
(neutral) position. Pausing in the neutral position
can result in gear clash and difficult shifting. If,

% [GF19350(F )04/96]Driving Off Road with 4-Wheel
Drive
[GF19400(F )04/96]
Most vehicles with four-wheel drive are
especially equipped for driving on sand, snow,
mud, or rough terrain and have operating
characteristics that are somewhat different from
conventional vehicles, both off and on the road.
The driving tips below will help you learn to
use four-wheel drive.
[GF19450(F )04/96]
q
Do not use 4WD LOW on dry, hard-surfaced
roads.
*
[GF19500(F )01/96]
q
Special maintenance procedures are necessary
after operating with drive components in
water.
*
[GF19550(F )01/96]
q
Manual locking hubs must be in LOCK
position before shifting into four-wheel drive.
[GF19600(F )04/96]
When using four-wheel drive, maintain steering
wheel control at all times, especially in rough
terrain. Since sudden changes in terrain can
result in abrupt steering wheel motion, make
sure you grip the steering wheel rim from the
outside. Do not grip the spokes.

Vehicle Loading/Towing
Information

[GF20825(F )01/96]
Your vehicle's load capacity is designated by
weight, not volume, so you cannot necessarily
use all available space with large or heavy loads.
Maximum safe vehicle weights as well as tire,
rim sizes and inflation pressures are specified for
your vehicle at the assembly plant on the Safety
Compliance Certification Label. The Certification
Label is located on the left front door lock facing
or the door latch post pillar.

RWARNING
To avoid losing control on slippery roads,
do not downshift into Low with the
automatic transmission when moving
faster than 20 mph (32 km/h). Do not
downshift into First with the manual
transmission when moving faster than
5 mph (8 km/h).
[GF24210(F )04/96]
RWARNING
The rear antilock brake system may not
prevent brake lock-up on extremely
slippery surfaces. Rear brake lock-up may
also occur while driving in four-wheel
drive because the transfer case couples the
front and rear axles together.

Traction-Lok Rear Axle (If equipped)
*
[GF24240(F )03/96]
This axle provides added drive away traction on
slippery surfaces, particularly when one or more
wheels are on a surface with poor traction.

[GF24250(F )03/96]
Extended use of other than matching size tires
on a Traction-Lok rear axle could result in a
permanent reduction in effectiveness. This loss of
effectiveness does not affect normal driving and
should not be noticeable to the driver.

To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.

1. Make sure that your vehicle will not move
or roll. If you have an automatic
transmission, put the gearshift in Park. If
you have a manual transmission, put the
gearshift in Reverse. Set the parking brake
and block the wheel that is diagonally
opposite the tire that you are changing.

vehicle from moving or slipping off the jack,
even if the vehicle is in P (Park) or 1 (First). To
prevent the vehicle from moving when you
change a tire, be sure the parking brake is set,
then block the wheel (both directions) that is
diagonally opposite (other side and end of the
vehicle) to the tire that is being changed.
