5-speed Manual Transmission

The manual transmission is syn-
chronized in all forward gears for
smooth operation. It has a lockout so
you cannot shift directly from Fifth
to Reverse. When shifting up or down, make sure you push the clutch
pedal down all the way, shift to the
next gear, and let the pedal up

gradually. When you are not shifting,
do not rest your foot on the clutch
pedal. This can cause your clutch to
wear out faster. Come to a full stop before you shift
into Reverse. You can damage the
transmission by trying to shift into
Reverse with the vehicle moving. Push down the clutch pedal, and
pause for a few seconds before shifting into Reverse, or shift into
one of the forward gears for a
moment. This stops the gears so
they won't "grind."
When slowing down, you can get extra braking from the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes from
overheating while going down a
steep hill. Before downshifting,
make sure engine speed will not go
into the tachometer's red zone in the
lower gear. Refer to the Maximum
Allowable Speeds chart.
Driving
Rapid slowing or speeding-up

can cause loss of control on

slippery surfaces. If you crash,

you can be injured.

Use extra care when driving on

slippery surfaces.ProCarManuals.comMain Menu Table of Contents s t

Towing a Trailer

Towing Safety

Your vehicle will not stop as quickly
with a trailer in tow. Leave extra distance between your vehicle and
other vehicles. Avoid braking or
turning suddenly. This could cause
the trailer to jackknife or possibly
turn over.
Keep in mind that your total vehicle
is now much longer. Leave more
room when making turns. The trailer
tracks a smaller arc than the vehicle
and can hit or run over something
that the vehicle misses. When
passing another vehicle, make sure
the trailer is clear before changing

lanes.
The vehicle/trailer combination is
more affected by crosswinds andbuffeting. When being passed by a
large vehicle, keep a constant speed and steer straight ahead. If there is
too much wind buffeting, slow down
to get out of the other vehicle's air

turbulence.

Towing a trailer puts an extra load on your vehicle. You should have
your vehicle serviced according to the "Maintenance Schedule undersevere driving conditions" on page 166. This extra load is magnified when
you are driving in hilly terrain.
Watch the temperature gauge closely when climbing hills. If it gets
near the hot area, turn off the airconditioning (if it is on). If this does
not reduce the heat, it may be
necessary to pull to the side of the
road and wait for the engine to cool. If the automatic transmission shifts
frequently between 3rd and 4th
gears, put it in D3. This will help prevent the transmission from
overheating. Help keep the brakes
from overheating by shifting to a
lower gear when going downhill.
If you have to stop while going uphill,do not hold the vehicle in place by
pressing on the accelerator. This can cause the automatic transmission to
overheat. Use the parking brake or
footbrake.

Spark Plugs

5. Put the new spark plug into the socket; then screw it into the hole.
Screw it in by hand so you do not

crossthread it.
6. Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn
after it contacts the cylinder head.)
Tightening torque:
13 lbf .
ft (18 N .
m, 1.8 kgf .
m)

Tighten the spark plugs carefully. A
spark plug that is too loose can
overheat and damage the engine. Overtightening can cause damage to
the threads in the cylinder head.

7. Install the spark plug cap.
8. Repeat this procedure for the other three spark plugs.
Reinstall the plug wire cover and
tighten the four nuts.

Taking Care of the Unexpected

This section covers the more-
common problems that motorists

experience with their vehicles. It
gives you information about how to safely evaluate the problem and what
to do to correct it. If the problem has stranded you on the side of the road,
you may be able to get going again. If not, you will also find instructions
on getting your vehicle towed.

Taking Care of the UnexpectedProCarManuals.comMain Menu s t

If Your Engine Overheats

The pointer of your vehicle's temperature gauge should stay in
the midrange under most conditions.It may go higher if you are driving up
a long steep hill on a very hot day. If
it climbs to the red mark, you shoulddetermine the reason.
Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine. Your vehicle can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam orspray coming from under the hood.
In either case, you should take
immediate action.
1. Safely pull to the side of the road. Put the transmission in Neutral or
Park and set the parking brake.
Turn off the heating and cooling system and all other accessories.
Turn on the hazard warning indicators. 2. If you see steam and/or spray
coming from under the hood, turnoff the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading(climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately. If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.
4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the
hood.

overheated engine can
seriously scald you.Do not open the hood if steam

is coming out.ProCarManuals.comMain Menu Table of Contents s t

If Your Engine Overheats

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot, so use caution. If you find a leak, it
must be repaired before you continue driving (see Towing on
page 250).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 124). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, before check-
ing the radiator. 9. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushingdown, to the first stop. This
releases any remaining pressure in
the cooling system. After the pressure releases, push down on
the cap and turn it until it comesoff. 10. Start the engine and set the
temperature control lever to
maximum. Add coolant to the
radiator up to the base of the filler
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and refilled with
the proper mixture as soon as you

can.

11. Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See Towing on
page 250.)
12. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on

tightly.

Taking Care of the Unexpected

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.ProCarManuals.comMain Menu Table of Contents s t
