Downloaded from www.Manualslib.com manuals search engine 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 “P” Park to hold
your vehicle in position on a hill.
Five-Speed Manual Transmission
This is your shift
pattern. Here’s how
to 1..
operate your
transmission:
0 1 (First Gear) - Press the clutch pedal and shift into “1” (First Gear).
Then, slowly let up on the clutch pedal as you press the accelerator
pedal.
You can shift into
“1” (First Gear) 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
“I” (First Gear), put the shift lever in “N” (Neutral) and let up on the
clutch. Press the clutch pedal back down. Then shift into “1” (First
Gear).
2 (Second Gear) - Press the clutch pedal as you let up on the
accelerator pedal and shift
into “2” (Second Gear). Then, slowly let up
on the clutch pedal
as you press the accelerator pedal.
0 3,4 and 5 (Third, Fourth and Fifth Gears) - Shift into “3” (Third
Gear),
“4” (Fourth Gear), and “5” (Fifth Gear) the same way you do for
“2” (Second Gear). Slowly let up
on the clutch pedal as you press the
accelerator pedal.

If you have this feature, your rear axle can give you additional traction on
snow, mud, ice, sand or gravel. It works like a standard axle most of the
time, but when one of the rear wheels has no traction and the other does, the
locking feature will allow the wheel with traction
to move the vehicle.
Parking Brake
-
To Set the Parking Brake:
To Release the Parking Brake:
Hold the regular brake
pedal down
with your
right foot. Push down
the parking brake
pedal with your left
foot. If the ignition is
on, the brake system
warning light will
come
on.
Hold the regular brake
pedal down. Pull the
brake release lever.
I 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.

Standard Cluster Digital Cluster
If you have a standard cluster, 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 been
operating your vehicle under normal driving conditions, you should pull
off
the road, stop your vehicle and turn off the engine as soon as possible.
If you have a digital cluster, a box around the temperature symbol will also
flash and a chime will sound when your engine is too hot.
Hot Coolant Can Burn you Badly! In Problems On The Road, this manual
explains what to do. See “Engine Overheating
” in the Index.

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
h11. 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 “N” (Neutral) , 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.
Stop your vehicle by applying the regular brakes. Apply the parking
brake.
Shift to “P’ (Park) (or to Neutral with the manual transmission) and,
while still braking, restart the engine.
Shift back to a low gear, release the parking brake, and drive straight
down.
If the engine won’t start, get out and get help.

Downloaded from www.Manualslib.com manuals search engine Making Turns
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 a different turn signal
flasher and extra wiring. The green arrows
on your instrument panel will
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights 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 kdh) to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission,
you should use “D” when towing a
trailer. Operating your vehicle in “D” when towing a trailer will minimize
heat buildup and extend the
life of your transmission. Or, if you have a
manual transmission with
fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
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 “P” (Park) yet, or into
gear for a manual transmission.
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.

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:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If
you get the overheat warning with no sign of steam, try this for a minute
or so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan speed and open the
3. If you’re in a traffic jam, shift to “N” (Neutral).
window as
necessary.
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 OFF THE 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.
When
you decide it’s
safe to
lift the hood,
here’s what you’ll see:
A. Coolant recovery
B. Radiator pressure
C. Engine fan tank
cap
If the
coolant inside the coolant recovery tank is boiling, don’t do anything
else until
it cools down.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
In cold weather, water can freeze and crack the engine, radiator, \
heater core
and other parts. Use the recommended coolant.
When the coolant in the coolant recovery tank is at or above the the ADD
mark, start your vehicle.
If the overheat warning continues, there’s one more thing you can try. You
can add the proper coolant mix directly to the radiator but be sure the
cooling system is cool before you do it.
