The added weight, length, and height of a trailer will affect your
vehicle's handling and performance, so driving with a trailer requires
some special driving skills and
techniques.
For your safety and the safety of
others, take time to practice driving
maneuvers before heading for the open road, and follow the guidelines
discussed below.
Towing Speeds and Gears
Driving slower than normal in all driving situations, and obey posted
speed limits for vehicles with trailers.
Use the D4 position when towing a
trailer on level roads. D3 is the
proper shift lever position to use
when towing a trailer in hilly terrain. (See "Driving on Hills" in the next
column for additional gear
information.) Making Turns and Braking
Make turns more slowly and wider
than normal. The trailer tracks a smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses. Allow more time and distance for braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknife or turn over.

Driving on Hills

When climbing hills, closely watch
your temperature gauge. If it nears the red (Hot) mark, turn the airconditioning off, reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shifts
frequently between 3rd and 4th
gears while going up a hill, shift to
D3.
If you must stop when facing uphill,
use the foot brake or parking brake. Do not try to hold the vehicle in
place by pressing on the accelerator, as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shift down to 2nd gear. Do not "ride" the brakes, andremember it will take longer to slowdown and stop when towing a trailer.

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.

9. Install the ignition coil. Reinstall the two hold-down bolts.
10.Push the wire connector onto the ignition coil. Make sure it locks in

place.

11.Repeat this procedure for the other five spark plugs.
12.Put the A/C tube back in place.

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 car towed.

I
f You r Engin e Overheat s

The pointer of your car's tempera- ture gauge should stay in the mid-range 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 should
determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine. Your car 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 or
spray 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 climate control and all
other accessories. Turn on the
hazard warning indicators.
2. If you see steam
and/or spray
coming from under the hood, turn
of

f the engine.
3. I

f 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.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.

I
f You r Engin e Overheat s
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.

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 Emergenc y
Towin g on page 292).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page170). 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 pushing
down, 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 comes off. 10. Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90° F/32° C). 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
plai
n 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 t

o the red mark, the engine
needs repair. (See Emergenc y
Towin g o

n page 29
2.)
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.

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.
