lower fuel economy) than SECOND GEAR (2).
You can use it on very
steep hills,
or in deep snow or mud. If the selector lever is put in FIRST
GEAR
(1) while the vehicle is moving forward, the transmission won’t
shift into FIRST GEAR
(1) until the vehicle is going slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to drive. This might
happen
if you were stuck in very deep sand or mud or were up
against a solid object. You could damage your transmission.
Also,
if you stop when going uphill, don’t hold your vehicle there
with only the accelerator pedal. This could overheat and damage
the transmission. Use your brakes or shift into
PARK (P) to hold
your vehicle in position on a hill.
Five-Speed Manual Transmission
.- I
This is your shift
pattern. Here’s how
to
operate your
transmission:
FIRST GEAR (1) - Press the clutch pedal and shift into FlRST GEAR (1).
Then, slowly let up on the clutch pedal as you press the accelerator pedal.
You can shift into FIRST GEAR (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 GEAR (1)’ put the shift lever in NEUTRAL, (N) and let up on the
clutch. Press the clutch pedal back down. Then shift into FIRST GEAR (1).

NOTICE: I
Driving with the parking brake on can cause your rear brakes \
to overheat. You may have to replace them, and you could also
damage other parts
of your vehicle.
If you are on a hill: See “Parking on Hills” in the Index. That section
shows how to turn your front wheels.
If you are towing a trailer and are parking on any hill: See “Towing a
Trailer” in the Index. That section shows what to
do first to keep the trailer

Downloaded from www.Manualslib.com manuals search engine For a single wiping cycle, turn the band to MIST. Hold it there until the
wipers start, then let
go. The wipers will stop after one wipe. If you want
more wipes, hold the band on MIST longer.
You can set the wiper speed for a long or short delay between wipes.
This
can be very useful in light rain or snow. Turn the band to choose the delay
time. The closer to
LO, the shorter the delay.
For steady wiping at low speed, turn the band away from you to the
LO
position. For high speed wiping, turn the band further, to HI. To stop the
wipers
, move the band to the off symbol.
Remember that worn or damaged wiper blades may prevent you from
seeing well enough to drive safely. To avoid damage, be sure to clear ice
and snow from the wiper blades before using them. If they’re frozen to the
windshield, carefully loosen or thaw them.
If your blades do become worn
or damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. The windshield wiper motor is
protected
from overload by a circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper
will stop until the motor cools.
Although the circuit is protected from electrical overload, overload due to
heavy snow, etc. may cause wiper linkage damage. Always clear ice and
heavy snow from the windshield before using your windshield wipers.
Windshield Washer
At the top of the
multifunction lever
there’s a paddle
marked with the
windshield washer
symbol and PUSH. To
spray washer fluid on
the windshield, push
the paddle.
The wipers will clear the window and then either stop or return to your
preset speed.
Driving without washer fluid can be dangerous. A bad mud splash can block
your vision. You could hit another vehicle or go
off the road. Check your
washer fluid level often.

rc E- -
This gage shows the
engine coolant
temperature.
If the
gage pointer moves into the red area, your
engine
is too hot!
It means that your engine coolant has overheated. If you have bee\
n
operating your vehicle under normal driving conditions, you shou\
ld pull off
the road, stop your vehicle and turn
off the engine as soon as possible.
Hot Coolant Can Burn you Badly! In Problems On The Road, this manual
explains what to do. See “Engine Overheating” in the Index.
Oil Pressure Gage
40
The oil pressure gage
shows the engine oil
pressure in psi (pounds per square
inch) when the engine
is running. Canadian
vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside temperature and oil
viscosity, but readings above the low pressure zone indicate the normal
operating range.
A reading in the low pressure zone may be caused by a dangerously low oil
level or other problems causing low oil pressure.

Downloaded from www.Manualslib.com manuals search engine Q: Are there some things I should not do when driving down a hill?
A: Yes? These are important because if you ignore them you could lose
control and have a serious accident.
When driving downhill, avoid turns that take you across the incline of
the hill.
A hill that’s not too steep to drive down may be too steep to
drive across. You could roll over if
you don’t drive straight down.
Never go downhill with the transmission in NEUTRAL (N), or with the
clutch pedal depressed in a manual shift. This is called
“free-wheeling.” Your brakes will have to do all the work and could
overheat and fade.
Q: Am I likely to stall when going downhill?
A: It’s much more likely to happen going uphill. But if it happens going
downhill, here’s what to do.
0 Stop your vehicle by applying the regular brakes. Apply the parking
0 Shift to PARK (P) (or to Neutral with the manual transmission) and,
brake.
while still braking, restart the engine.
0 Shift back to a low gear, release the parking brake, and drive straight
down.
0 If the engine won’t start, get out and get help.
Driving Across an Incline
Sooner or later, an off-road trail will probably go across the incline of a hill.
If this happens,
you have to decide whether to try to drive across the incline.
Here are some things to consider:
0 A hill that can be driven straight up or down may be too steep to drive
across. When you
go straight up or down a hill, the length of the wheel
base (the distance from the front wheels to the rear wheels) reduces the
likelihood the vehicle will tumble end over end. But when
you drive
across an incline, the much more narrow track width (the distance
between the left and right wheels) may not prevent the vehicle from
tilting and rolling over. Also, driving across
an incline puts more
weight
on the downhill wheels. This could cause a downhill slide or a
rollover.
0 Surface conditions can be a problem when you drive across a hill.
Loose graveI, muddy
spots, or even wet grass can cause your tires to
slip sideways, downhill.
If the vehicle slips sideways, it can hit
something that will trip it (a rock,
a rut, etc.) and roll over.

Downloaded from www.Manualslib.com manuals search engine Passing
You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left. To move the trailer to the
right, move your hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
NOTICE:
Making very sharp turns while trailering could cause the traile\
r
to come in contact with the vehicle. Your vehicle could be
damaged. Avoid making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than normal. Do this
so your trailer won’t strike soft shoulders, curbs, road signs, trees, or other
objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra wiring and a
heavy-duty
turn signal flasher (included in the optional trailering package).
The green arrows on your instrument panel will flash whenever you signal a
turn or lane change. Properly hooked up, the trailer lamps will also flash,
telling other drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your instrument panel will flash
for turns even if the bulbs on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or steep
downgrade. If you don’t shift down, you might have to use your brakes
so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around 45 mph
(70 Wh) to reduce the possibility of engine and transmission overheating.
4-45

Downloaded from www.Manualslib.com manuals search engine When towing at high altitude on steep uphill grades, consider the following:
Engine coolant will boil at a lower temperature than at normal\
altitudes.
If
you turn your engine off immediately after towing at high altitude on steep
uphill grades, your vehicle may show signs similar
to engine overheating.
To avoid this,
let the engine run while parked (preferably on level ground)
with the automatic transmission in PARK
(P) (or the manual transmission
out of gear and the parking brake applied) for a few minutes before turni\
ng
the engine off. If
you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hills
You really should not park your vehicle, with a trailer attached, \
on a hill. If
something goes wrong, your rig could start
to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into PARK (P)
yet, or into
gear for a manual transmission. Then turn your wheels into the curb if \
facing downhill or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes\
until the
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
then
shift into PARK (P), or REVERSE
(R) for a manual transmission.
5. If you have a four-wheel-drive vehicle with a manual transfer case
shift lever, be sure
the transfer case is in a drive gear - not in
NEUTRAL
(N).
6. Release the parking brake.

If Steam Is Coming From Your Engine
NOTICE:
If your engine catches fire because you keep driving with no
coolant, your vehicle can be badly damaged. The costly repairs
would not be covered by your warranty.

Downloaded from www.Manualslib.com manuals search engine If No Steam IS Coming From Your Engine
If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
e Tow a trailer. See "Driving on Grades" in the Index.
If
YOU get the overheat warning with no sign of steam, try this for a minute
or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3. If you're in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the
highest gear while driving
- AUTOMATIC OVERDRIVE (@) or
DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can drive. Just \
to be safe,
drive slower for about ten minutes.
If the warning doesn't come back on,
you
can drive normally.
If the warning continues, pull over, stop, and park your vehicle \
right away.
If there's still no sign of steam, push the accelerator until the engine speed is
about twice as fast
as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now
see if the warning stops.
But then, if you still have the warning,
turn oflthe engine and get everyone
out
of the vehicle until it cools down.
You may decide not to lift the hood but to get service help right away.
