Towing a Trailer
A CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy. the
brakes may not work well
-- or even at all. Yo
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section.

To identify what the vehicle
trailering capacity is for your vehicle, you should read
the information in “Weight of the Trailer”. that appears
I later in this section. But trailering is different than just
driving your vehicle by itself. Trailering means changes

safe trailering takes correct equipment, and it has to be

That’s the reason for this section. In it are many
time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of
I your passengers. So please read this section carefully
Load-pulling components such as the engine, transaxle, wheel assemblies, and tires are forced to work harder
against the drag of the added weight. The engine is
greater loads, generating extra heat. What’s more, the
trailer adds considerably to wind resistance, increasing
the pulling requirements.

The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them.
Safety Chains
You should always attach chains between your vehicle
and. your trailer. Cross the safety chains under the
tongue of the trailer
so that the tongue will not drop to
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for
attaching safety chains. Always leave just enough slack
so you can turn with your rig. And, never allow safety
chains to drag
on the ground.
Trailer Brakes
Does your trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes
so
you’ll be able to install, adjust and maintain them
properly. Because you have anti-lock brakes, do not try
to tap into your vehicle’s brake system. ff you do, both
brake systems won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not.nearly
so
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform,
safety chains, electrical connector, lights, tires and
mirror adjustment. If the trailer has electric brakes, start
your vehicle and trailer moving and then apply the
trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection
at the same time.
During your trip, check occasionally to be sure that the
load
is secure, and that the lights and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.

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.
d
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
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.
nrn 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, use the highest gear. possible. If
you cannot maintain posted speeds, driving at a lower
speed may help avoid overheating your engine and
transaxle.
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.

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system, and brake adjustment.
Each of these is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before
you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.
I 1. Apply your regular brakes and hold the pedal down
while you:

2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

transaxle in ‘W’ (Neutral).
3. Turn off the ignition on both vehicles. Turn off all
lights that aren’t needed, and radios. This will avoid
sparks and help save both batteries. And it could
save your radio!
4. Open the hood and locate the batteries.
/1 CAUTION:
An electric fan can start up even when the eng
is not running and can injure you. Keep hands
clothing and tools away from
electric fan.
Find the positive (+) and negative (-) terminals on
each battery.

P-
When your vehicle is being towed, have the ignition key
off. The steering wheel should be clamped in a
straight-ahead position, with a clamping device designed
for towing service.
Do not use the vehicle’s steering
column lock for this. The transaxle should be in Neutral
and the parking brake released.
Don’t have your vehicle towed on the front wheels,
unless you must.
If the vehicle must be towed on the
front wheels, don’t go more than
35 mph (57 kmh) or
farther than
50 miles (80 km) or your transaxle will be
damaged. If these limits must be exceeded, then the
front wheels have to be supported on a dolly.

.If a Tire Goes Flat Changing a Flat Tire
It’s unusual for a tire to “blow out” while you’re driving,
especially
if you maintain yourtires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
1
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side: Take your foot off the
accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, then gentlv
I. - to a
stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to
a stop, well off the road if possible.
If your tire goes flat, the next section shows how to use
your jacking equipment to change a flat tire safely.
If a tire goes flat, avoid further tire and wheel damage
by driving slowly
to a level place. Turn on your hazard
warning flashers.
A “-CAUTION:
I Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured. Find
a level place to change your tire.
To help prevent
the vehicle from moving:
1. Set the parking brake K- Ay.
2. Put the shift lever in “P” (Park
3. Turn off the engine.
