When to usej(Overdrive)
*
[DR09600( ALL)04/95]
This is the normal driving position. As the
vehicle picks up speed, automatic upshifts to
second, third and fourth gears will occur when
jOverdrive is chosen on the selector and the
transmission control switch has not been
pressed. The transmission will shift into the
correct gear when the right speed is achieved,
for the accelerator pedal position you have
chosen.

When to use Drive
*
[DR09800( ALL)05/95]
You will note that there isn't a drive position on
your gearshift indicator. However, you will find
a Transmission Control Switch and an indicator
light labeled ªOverdriveº located on the end of
the gearshift lever. Press this switch and the
word ªOFFº will illuminate on the shift lever
knob. With the word ªOFFº illuminated, the
transmission will operate in gears one through
three. Operating in the Overdrive ªOFFº mode
gives more engine braking than Overdrive and
is useful for descending hills or when towing.

When starting your vehicle, the overdrive system
will automatically be in the normal overdrive
mode.
*
[DR10000( ALL)03/94]
If the Transmission Control Indicator Light is
flashing on and off steadily, a transmission
system malfunction was detected. The
transmission will operate in a failure
management mode and may have harsh
engagements, firm shift feel, or abnormal shift
schedule. If this condition persists, damage to
the transmission could occur. Contact your
dealer as soon as possible.

[DR10100( ALL)01/95]
When to use 2 (Second)
*
[DR10200( ALL)01/95]
Use 2 (Second) to start-up on slippery roads or
to provide additional engine braking on
downgrades. This position provides 2 (Second)
gear operation only.
*
[DR10300( ALL)01/95]
When to use 1 (Low)
*
[DR10400( ALL)04/95]
Use 1 (Low) to provide maximum engine
braking on steep downgrades. Upshifts from 1
(Low) can be made by manually shifting to 2
(Second) orj(Overdrive). Selection of 1 (Low)
gear provides only low gear operation from
start-up. Selection of 1 (Low) while at higher
speeds provides a shift to second gear, and a
shift to first gear will occur after the vehicle
decelerates to the proper speed.

P (Park)
*
[DR10600( ALL)03/94]
Always come to a complete stop before you shift
into P (Park). This position locks the
transmission and prevents the rear wheels from
turning. To securely latch the gearshift in the P
(Park) position, pull it toward you, push it
completely counterclockwise against the stop,
and then push it toward the instrument panel.
*
[DR10650( ALL)03/94]
The gearshift is securely latched in P (Park) if
you cannot rotate it in a clockwise direction
without lifting it toward you.

[DR10700( ALL)05/95]
RWARNING
Always set the parking brake fully and
make sure that the gearshift is securely
latched in P (Park).
[DR10725(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.

Power Braking
*
[DR11275( ALL)03/94]
Increasing the engine speed above idle without
vehicle movement (such as holding the brake) in
a forward or reverse gear causes transmission
stall.

[DR11500(B F )01/95]
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).
*
[DR11600(B F )03/91]
To move the vehicle, release the clutch slowly
and at the same time press down slowly on the
accelerator so that the vehicle accelerates.
*
[DR11700(B F )03/95]
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.

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.

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.

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.

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.

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.

*
[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

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.
