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.

5. Once R (Reverse) is engaged, slowly release
the clutch pedal from the floor.
*
[DR13000(B F )03/94]
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.

[DR15100(B F )03/95]
When you slow down or climb a steep hill,
always downshift before the engine starts to lose
power. Downshifting reduces the chance of
stalling and gives your vehicle better acceleration
to increase speed again.

[DR15200(B F )03/95]
When you drive down steep hills, downshifting
helps you keep a safe speed and helps prevent
unnecessary wear on the brakes.
*
[DR15300(B F )03/95]
When you come to a stop, do not downshift
through each gear. Disengage the clutch and use
the brake as necessary. Downshifting through
the gears decreases your vehicle's fuel economy.
*
[DR15400(B F )05/95]
RWARNING
Continued use of a damaged or worn
clutch, prolonged clutch slippage or
downshifting at excessive speeds can
result in a failure of the engine,
transmission or clutch components.

Transmission Function
*
[DR15600(B F )03/91]
Upshift at the speeds specified in the chart
available for your engine and transmission. All
forward gears are synchronized allowing you to
shift into them with your vehicle in motion. The
clutch pedal should be fully depressed when
shifting.
*
[DR15625(B F )04/94]
NOTE: Shifting during extremely low rpm's
can result in a momentary audible
rattle which disappears as vehicle
rpm's are increased. Shifting at higher
speeds will eliminate this sound.

[DR15700(B F )03/95]
Parking
*
[DR15800(B F )01/95]
To park your vehicle, apply the service brake
pedal, and shift into N (Neutral) while still
maintaining pressure on the service brake. Set
the parking brake fully. Shift into first and turn
off the ignition.

RWARNING
Do not park your vehicle in Neutral, it
may move unexpectedly and injure
someone. Use 1 (First) gear and set the
parking brake fully.
[DR15903(B F )05/95]
When the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the
automatic transmission is in P (Park) or the
manual transmission is in gear.
*
[DR15906(B F )05/95]
RWARNING
Do not leave the vehicle unattended with
the transfer case in the N (Neutral)
position. Always set the parking brake
fully and turn off the ignition when
leaving the vehicle.

[DR15915( ALL)01/95]
Steering Your Vehicle
%*
[DR15945( ALL)01/95]
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
%*
[DR15950( ALL)04/95]
If the amount of effort needed to steer your
vehicle changes at a constant vehicle speed, have
the power steering system checked. If the power
steering system breaks down (or if the engine is
turned off), you can steer the vehicle manually
but it takes more effort.
*
[DR15960( ALL)01/95]
Never hold the steering wheel to the extreme
right or left for more than five seconds if the
engine is running. This can damage the power
steering pump.

4x4 Systems Ð Lever Operated
*
[DR16220(B F )06/94]
The lever operated transfer case can be placed
into four positions. The 2H position is the
two-wheel drive position in which power is
delivered only to the rear axle. The 4H position
provides four-wheel drive with power delivered
to the front and rear axles for increased traction.
The 4L position provides four-wheel drive with
power delivered to the front and rear axles
when the above average power is required at
reduced speeds. In the N (neutral) position, there
is no power delivered to either axle.
[DR16225(B F )05/95]
When the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the
automatic transmission is in P (Park) or the
manual transmission is in gear.

[DR16820(B F )06/94]
To shift between 4H and 4L:
*
[DR16851(B F )05/91]
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,
while shifting between 4H and 4L, the transfer
case gets stuck in the N (neutral) position or is
difficult to shift into either 4H or 4L, it may be
necessary to let the vehicle roll slightly and/or
turn off the engine (particularly on vehicles
equipped with automatic transmissions).
*
[DR16880(B F )03/91]
To shift into and out of N (neutral)
[DR16940(B )03/91]
To shift into N (neutral), stop the vehicle and
engage the parking brake. Place the automatic
transmission into NEUTRAL or depress the
clutch. From either the 4H or 4L position, push
the transfer case shift knob down (toward the
ground) and move the transfer case shift lever to
the N (neutral) position. The N (neutral) position
should only be used for vehicle towing.

Stop the vehicle and engage the manual locking
hubs by turning both hub lock selector knobs
clockwise to the LOCK position. Move the

position. After both hubs have been turned to
the LOCK position, shifts between 2H and 4H
(or 4H to 2H) may take place at any speed.

However, the front driveline will remain
engaged to the front wheels until the manual
locking hubs are disengaged. To disengage the
manual locking hubs, stop the vehicle and rotate
both hub lock selector knobs counter-clockwise
to the FREE position.
*
[DR17270(B F )06/94]
Operating in 2H with the hubs in the LOCK
position increases fuel consumption, noise,
vibration, and wear. For prolonged 2H operation
on dry pavement, set the manual locking hubs
to the FREE position.

4x4 SYSTEMS-TOUCH DRIVE
*
[DR17601(B F )06/94]
The Touch Drive 4x4 system functions in three
modes. In Two Wheel Drive mode, power is
delivered only to the rear axle at normal road
speed. The 4H position provides four-wheel
drive with power delivered to the front and rear
axles for increased traction. The 4L position
provides four-wheel drive with power delivered
to the front and rear axles when the above
average power is required at reduced speeds.
*
[DR17630(B F )06/94]
Four wheel drive operation (4x4 or 4x4 LOW
RANGE) on dry pavement is not recommended.
Operating the vehicle in four-wheel drive on dry
pavement will increase noise, vibration, tire
wear, decrease fuel economy, and make
four-wheel drive disengagement difficult for the
transfer case.

[DR18080(B F )06/94]
For example:
*
[DR18110(B F )06/94]
If you were driving the vehicle forward in
4x4, the automatic locking hubs will
disengage the next time the vehicle is driven
in reverse in Two-Wheel Drive for
approximately 10 feet (3 meters) in a straight
line.
*
[DR18140(B F )06/94]
If you were driving the vehicle in reverse in
4x4, the automatic locking hubs will
disengage the next time the vehicle is driven
forward in Two-Wheel Drive for
approximately 10 feet (3 meters) in a straight
line.
*
[DR18170(B F )01/95]
Operating in two-wheel drive mode with the
hubs locked increases fuel consumption, noise,
vibration, and wear. For prolonged two-wheel
drive operation on dry pavement, disengagement
of the automatic locking hubs, which is not
required for two-wheel drive operation, stops all
movement of front-wheel drive components
while operating in two-wheel drive.
*
[DR18230(B F )03/91]
To shift from 4x4 to 4x4 LOW RANGE:
*
[DR18290(B F )06/92]
Stop the vehicle and place the automatic
transmission in NEUTRAL or depress the clutch
on vehicles with a manual transmission. Push
the LOW RANGE button on the instrument
panel to shift the transfer case from 4x4 to 4x4
LOW RANGE. Both the 4x4 and LOW RANGE
lights are now lit.
*
[DR18300(B F )08/94]
NOTE: The vehicle must already be in 4x4
before pushing the Low Range Button.
