Manual Transmission Operation
5-Speed
This is your shift pattern. Here’s how to
operate your transmission:
FIRST (1): Press the clutch pedal and shift into
FIRST
(I). Then, slowly let up on the clutch pedal as
you press the accelerator pedal.
You can shift into FIRST (1 ) when you‘re going less
than
20 mph (32 km/h). If you’ve come to a complete
stop and it’s hard
to shift into FIRST ( 1 ): put the shift
lever
in NEUTRAL (N) and let up on the clutch. Press
the clutch pedal back down. Then shift into FIRST
(1 ).
SECOND (2): Press the clutch pedal as you let up on
the accelerator pedal and shift into
SECOND (2). Then,
slowly let up on the clutch pedal as you press the
accelerator pedal.
THIRD, FOURTH AND FIFTH (3,4 and 5): Shift
into THIRD
(3). FOURTH (4) and FIFTH (5) the same
way you do for
SECOND (2). Slowly let up on the
clutch pedal as you press the accelerator pedal.
To stop, let
up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal. and shift to NEUTRAL
(N).
2-21

NEUTRAL (N): Use this position when you start or
idle your engine.
REVERSE (R): To back up, press the clutch pedal, wait
about six seconds, then shift into
REVERSE (R). Then
let
up on the clutch pedal slowly while pressing the
accelerator pedal.
I NOTICE:
Shift to REVERSE (R) only after your vehicle
is stopped. Shifting to REVERSE
(R) while
your vehicle
is moving could damage
your transmission.
Use REVERSE (R), along with the parking brake. for
parking your vehicle.
Shift Light
SHIFT
If you have a manual
transmission. you have a
SHIFT light.
This light
will show you when to shift to the next higher
gear for best fuel economy.
When this
light comes on, you can shift to the next
higher gear
if weather, road and traffic conditions let
you. For the best fuel economy, accelerate slowly
and
shift when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the
SHIFT light when you downshift.

To shift into or out of 4LO:
1. The vehicle must be moving less than 3 mph
(4.8 km/h) with the transmission in NEUTRAL (N)
for an automatic transmission. For a manual
transmission, the clutch pedal must be engaged.
The preferred method
for shifting into or out of 4LO
is to have your vehicle moving I to 2 tnph (I .6 to
3.2 km/h).
2. Press the transfer case shift button and shift in one
continuous motion.
Don’t pause
in N SET PARK BRAKE as you shift into
or out of
4L0, or your gears could clash.
Remember that driving
in 4HI or 4LO may reduce fuel
economy. Also, driving in four-wheel drive on dry
pavement could cause your tires to wear faster and
make your transfer case harder to
shift and reduce
powertrain longevity.
Electronic Transfer Case (If Equipped)
If your four-wheel-drive
vehicle has the electronic
transfer case, the transfer
case switches are above
the radio controls.
Use these switches to shift into and out
of four-wheel
drive.
You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged
in
two-wheel drive. When this lamp is lit, it is about
one-half
as bright as the others.
4HI: This setting engages your front axle to help drive
your vehicle. Use
4HI when you need extra traction, such
as on snowy or icy roads. 01- in most off-road situations.
2-26

4LO: This setting also engages your front axle to give
you extra traction. You may never need 4LO. It sends
the maximum power to all
four wheels. You might
choose 4LO
if you were driving off-road in sand, mud
or deep snow and climbing or descending steep hills.
Indicator lights
in the switches show you which setting
you are
in. The indicator lights will come on briefly when
you turn on
the ignition and one will stay on. If the lights
do not come
on, you should take your vehicle in for
service.
An indicator light will flash while shifting. It will
remain illuminated when the shift is completed.
Shifting from 2HI to 4HI
Press and release the 4HI switch. This can be done at
any speed. and the front axle will lock automatically.
Shifting from 4HI to 2HI
Press and release the 2HI switch. This can be done at
any speed. and the. front axle will unlock automatically.
Shifting from 2HI or 4HI to 4LO
To
shift from 2HI or .CHI to 4LO. the vehicle must be
stopped or moving less than
3 rnph (4.8 k~nh) with the
transmission
in NEUTRAL (N) in vehicles equipped with an
automatic transmission or the clutch pedal engaged
in
vehicles equipped with a manual transmission. The
preferred method for shifting into 4LO is to have your
vehicle moving
1 to 2 mph (I .6 to 3.2 kmh). Press
and release
the 4LO switch. You must wait for the
4LO indicator light to stop flashing and remain
illuminated before shifting your transmission into
gear or releasing
the clutch pedal.
If the 4L0 switch is pressed when your vehicle is
in
gear and/or moving, the 4LO indicator light will flash
for
30 seconds and not complete the shift unless your
vehicle is moving slower than
3 tnph (4.8 km/h) and
the transmission
is in NEUTRAL (N) or the clutch
pedal engaged.
On automatic transmission equipped vehicles,
if your
transfer case does
not shift into 4LO. your transmission
indicator switch may reyuire adjustment. With
your
transmission in NEUTRAL (N)! press and release the
4L0 switch. While the 4LO indicator light is flashing.
shift yo~lr transmission into PARK (P). Wait unlil the
4L0 indicator light remains illuminated before shifting
your trrmstnission
into gear. This will get you into 4LO.
but you should take
your vehicle in for service to restore
normal operation.

Shifting from 4LO to 4HI or 2HI
To shift from 4LO to 4HI or 2H1, your vehicle must be
stopped or moving
less than 3 mph (4.8 kndh) with the
transnJission
in NEUTRAL (N) or the clutch pedal
engaged. The preferred method for shifting out of
4LO is to have your vehicle moving
1 to 2 mph (1.6 to
3.2 kdh). Press and release the 4HI switch. You must
wait for the
4HI indicator light to stop flashing and
remain illuminated before shifting your transmission
into gear
or releasing the clutch pedal.
If the 4Hi switch is pressed when your vehicle is in gear
and/or moving. the 4HI indicator light
will flash for
30 seconds but not complete the shift unless the
vehicle is moving slower than
3 nlph (4.8 km/h) and
the transmission is in NEUTRAL (N) or the clutch
pedal engaged.
On automatic transmission equipped vehicles. if your
transfer case does not
shift into 4H1, your transmission
indicator switch
may require adjustment. With your
transmission
in NEUTRAL (N), press and release the
4HI switch. While the 4HI indicator light is flashing,
shift your transmission into PARK
(P). Wait until the
4HI indicator light remains illuminated before shifting
your transmission into gear. This
will get you into 4H1,
but you should take your vehicle in for service to restore
norrnal operation.

Cruise Control (If Equipped)
With cruise control, you can
maintain
a speed of about
25 mph (40 krn/h) or more
without keeping your foot
on the accelerator. This
can
really help on long trips.
Cruise control
does not
work at speeds below about
25 rnph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut
off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will
shut off.
A CAUi ION:
I
Cruise control can be dangerous where you
can’t drive safely at
a steady speed. So,
don‘t use your cruise control on winding
roads or in heavy traffic.
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.
Cruise control can be dangerous on

Engine Fan Noise If a Tire Goes Flat
This vehicle has a clutched engine cooling fan. When
the clutch is engaged,
the fan spins faster to provide
more air to cool the engine.
In most everyday driving
conditions, the clutch
is not engaged. This improves
fuel economy and reduces
fan noise. Under heavy
vehicle loading, trailer towing and/or high outside
temperatures, the
fan speed increases when the clutch
engages.
So you may hear an increase in fan noise. This
is normal and should not be mistaken as the
transmission slipping
or making extra shifts. It is merely
the cooling system functioning properly. The fan will
slow down when additional cooling is not required and
the clutch disengages.
You
may also hear this fan noise when you start he
engine.
It will go away as the fan clutch disengages. It's
unusual
for a tire to "blow out" while you're driving,
especially
if you maintain your tires properly. If air goes
out of
a tire, it's muc11 more likely to leak out slowly.
But if you should ever have a "blowout." here are a few
tips about what
to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to ~naintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout. particularly on a curve, acts much like a
skid and may require the same correction you'd use in a
skid. In any rear blowout, remove yo~~r foot from the
accelerator pedal. Get the c.ehicle under control
by
steering the way ~OLI want the vehicle to go. It may be
very bumpy
and noisy. but you can still steer. Gently
brake to
a stop -- well off the road if possible.

How to Add Fluid
Here's how to add fluid. Refer to the Maintenance
Schedule to determine what kind
of fluid to use. See
"Recommended Fluids and Lubricants"
in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level up
to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch system in your vehicle is
self-adjusting.
A slight amount of play ( 1/4 inch to
1/2 inch or ti lnm to 12 mm) in the pedal is normal.
It isn't a good idea to "top OW' your clutch fluid. Adding
fluid won't correct
a leak. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule. Owner Checks and
Services. to determine how often you should check the
fluid level
in your clutch master cylinder reservoir and
for the proper fluid. See "Owner Checks and Services''
and "Recommended Fluids and Lubricants"
in
the Index.
6-19

At Least Twice a Year Automatic Transmission Check
Check the transmission fluid level: add if needed. See
"Automatic Transmission"
in the Index. A fluid loss
may indicate
a problem. Check the system and repair
if needed.
Restraint System Check
Make sure the safety belt reminder light and all your
belts. buckles, latch plates, retractors and anchorages are
working properly. Look
for any other loose or damaged
safety belt system parts.
If you see anything that might
keep
a safety belt system from doing its .job, have it
repaired. Have any torn or frayed safety belts replaced.
Also
look. for any c.)pened or broken air bag covers, and
have them repaired or replaced. (The air
bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for ~vear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield.
Also see "Wiper Blades.
Cleaning"
in the Index.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
"Manual Transmission"
in the Index. Check for leaks.
A fluid loss ITI~~ indicate a problem. Have the system
inspected and repaired
if needed.
Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
"Hydraulic Clutch Fluid" in the Index. A fluid loss in
this system could indicate a problem. Have the system
inspected and repaired at once.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified
in Part D.
Body Lubrication Service
Lubricate all body door and fuel door hinges, rear
compartment hinges, latches and locks including the
moving seat hardware. Lubricate the hood safety lever
