to read.

Downloaded from www.Manualslib.com manuals search engine 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
“P” Park to hold
your vehicle in position on
a hill.
Five-Speed Manual Transmission
This is your shift
pattern. Here’s how to
operate your
transmission:
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
“1” (First Gear), put the shift lever in“N” (Neut\
ral) and let up
on the
clutch. Press the clutch pedal back down. Then shift into
“1” (First
Gear).
0 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 y\
ou
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.

NOTICE:
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
from moving.
Shifting Into ‘6P’’ (Park)
(A utomaticTransmission Models Only)
1. Hold the brake pedal down with your right foot and set the parking
brake.

If your vehicle has
four-wheel anti-lock
brakes, it will have
this yellow light.
3
With anti-lock, this light will go on when you start your engine and may
stay on for several seconds. That’s normal. If the light doesn’t come \
on,
have it fixed
so it will be ready to warn you if there is a problem.
If the light stays on, or comes on when you’re driving, your vehic\
le needs
service.
If the regular brake system warning light isn’t on, you still \
have
brakes, but you don’t have anti-lock brakes.
If the regular brake system
warning light is also on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier in this part.
Engine Coolant Temperature Gage
I 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 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.

Downloaded from www.Manualslib.com manuals search engine Driving On Grades
Reduce speed and shift to a lower gear before you start dawn 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 km/h) 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
rrianual 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
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
gear
for
a manual transmission.
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
then
shift into
“P” (Park), or “R” (Reverse) 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 “N” (Neutral).
6. Release the parking brakes,

You will find a coolant temperature gage on your vehicle’s instr\
ument
panel.
If Steam Is Coming From Your Engine
NOTICE:
If your engine catches fire because you keep driving with no
coolant, your vehicle cdh be badly damaged. The costly repairs
would not be covered by your warranty.

Downloaded from www.Manualslib.com manuals search engine /f 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.
0 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
window as necessary.
3.
If you’re in a traffic jam, shift to “N” (Neutral).
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 tank
B. Radiator pressure
C. Engine fan
cap
If the coolant inside the coolant recovery tank is boiling, don’t do anything
else until it cools down.
