Do not tow a trailer if your vehicle is
equipped with the
2.3L OHC or Quad
4 Engine (Code 3 or D).
Your vehicle can tow a trailer if it is
equipped with the
2.3L High Output

4 (Code A) or 3300 V6 (Code N)
engine and proper trailer towing
equipment. To identify what the vehicle
trailering capacity is for your vehicle,
you should read the information
in
Weight of the Trailer that appears later in
this section. But trailering is different
than just driving your vehicle by itself.
Trailering means changes in handling,
durability, and fuel economy. Successful, safe trailering
takes correct equipment,
and it has to be used properly. 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 your passengers.
So please read
this section carefully before you pull a
trailer.
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 required to operate at relatively higher
speeds and under greater loads, generating
extra heat. What’s more, the trailer adds
considerably to wind resistance,
increasing the pulling requirements.

If Bu Do Decide to Pull a Trailer
If you do, here are some important
points.
There are many different laws having
to do with trailering. Make sure your rig will be legal, not only where you
live but
also where you’ll be driving.
A good source for this information can
be state or provincial police.
Consider using a sway control. You
can ask a hitch dealer about sway
controls.
a Don’t tow a trailer at all during the
first
500 miles (804 km) your new
vehicle is driven. Your engine, axle or
other parts could
be damaged.
Then, during the first 500 miles
(804
km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and
don’t make
starts at full throttle. This
helps your engine and other parts of
your vehicle wear in at the heavier
loads.
Three important considerations have
to do with weight:
161
I. Weight of the Trailer
How heavy can a trailer safely be? It
should never weigh more than
1,OOO
pounds (450 kg).
But even that can be too heavy. It
depends on how you plan to use your
rig. For example, speed, altitude, road
grades, outside temperature and how
much your vehicle is used to pull a
trailer are
all important. And, it can
also depend on any special equipment
that you have
on your vehicle.

Weight of the Trailer Tongue
The
tongue load (A) of any trailer is
an
important weight to measure
because it affects the total capacity
weight
of your vehicle. The capacity
weight includes the curb weight of the
vehicle, any cargo you may carry in it,
and the people who will be riding
in
the vehicle. And if you will tow a
trailer, you must subtract the tongue
load from your vehicle’s capacity
weight because your vehicle will be carrying that weight, too. See the
Index under Loading Your Vehicle for
more information about your vehicle’s
maximum load capacity. The trailer tongue
(A) should weigh 10 %
of the total loaded trailer weight (B).
After you’ve loaded your trailer, weigh
the trailer and then the tongue, separately, to
see if the weights are
proper. If they aren’t, you may be able
to get them right simply by moving
some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated
to the limit for cold tires. You will find
these numbers on the Certification
label at the rear edge of the driver’s
door
(or see the Index under Ere
Loading). Then be sure you don’t go
over the
GVW limit for your vehicle.

Hitches
It’s important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few
reasons why you’ll need the right hitch.
Here are some rules to follow:
Will you have to make any holes in the
body
of your vehicle when you install
a trailer hitch? If you do, then be sure
to seal the holes later when you remove
the hitch. If you don’t seal them, deadly
carbon monoxide (CO) from your
exhaust can get into your vehicle. (See
the
Index under Carbon Monoxide in
Exhaust.) Dirt and water can, too.
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. And because
you have anti-lock brakes, do not try to
tap into your vehicle’s brake system. If
you do, both brake systems won’t work
well, or at all.

Your Driving and the Road
Driving with a lbiler
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.
164
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.
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.
ProCarManuals.com

Turn Signals When Towing a ’Railer
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.
If you have a manual transaxle 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 transaxle.
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.

4. Reapply the regular brakes. Then
apply your parking brake, and then shift to
P (Park), or R (Reverse) for a
manual transaxle.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a
Hill
1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and
of the chocks.
store the chocks.
Maintenance When Tmiler 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 overfiil),
engine oil, belts, cooling system, and
brake adjustment. Each
of these is
covered
in this manual, and the Ida
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.
