Don’t tap into your vehicle’s brake system if the
trailer’s brake system will use more than
0.02 cubic
inch
(0.3 cc) of fluid from your vehicle’s master
cylinder. If it does, both braking systems won’t work
well. You could even lose your brakes.
Will the trailer
parts take 3,000 psi (20 650 kPa) of
pressure? If not, the trailer brake system must not be
used with your vehicle.
If everything checks out this far, then make the brake
fluid tap at the port on the master cylinder that sends
fluid to the rear brakes. But don’t use copper tubing
for this. If you do, it will bend and finally break off.
Use steel brake tubing.
Driving with a Trailer
I
you have a rear-most window open and you
pull
a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can’t see
or smell CO. It can cause unconsciousness or
death. (See “Engine Exhaust” in the Index.) To
maximize your safety when towing
a trailer:
Have your exhaust system inspected for leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
0 If exhaust does come into your vehicle
through
a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
MAX A/C because it only recirculates the
air inside your vehicle. (See “Comfort
Controls” in the Index.)

Downloaded from www.Manualslib.com manuals search engine 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 as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, 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 lamps 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.

Downloaded from www.Manualslib.com manuals search engine Making Turns
NOTICE:
Making very sharp turns while trailering could cause the trailer
to come in contact with the
vehicle.
Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring (included in the optional trailering package).
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked
up, the trailer lamps
drivers you’re about to turn, will
also flash, telling other
change lanes or stop. When
towing a trailer, the 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, shift down and reduce your
speed
to around 45 mph (70 kdh) to reduce the
possibility of engine and transmission overheating.
When towing
at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating.
To avoid this, let the
engine
run while parked (preferably on level ground)
with the automatic transmission in
PARK (P) for a few
minutes before turning the engine off. If you do get the
overheat warning, see “Engine Overheating” in
the Index.

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
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 shift to
PARK (P).
5. Release the regular brakes.
PARK (P) yet.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
0 Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
:ks.
3. Drive slowly until the trailer is clear of the choc
4. Stop and have someone pick up and store the chocks.
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 transmission fluid (don’t
overfill), engine oil, axle lubricant, 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.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
If you have the optional trailering package, your vehicle
will have an eight-wire
harness, including the center
high-mounted stoplamp battery feed wire. The harness
is stored
on the passenger’s side of the vehicle near the
rear wheel well. This harness has
a 30 amp battery feed
wire and
no connector, and should be wired by a
qualified electrical technician. After choosing an
aftermarket trailer mating connector pair, have the
technician attach one connector to
the eight-wire trailer
harness and the other connector to the wiring harness on
the trailer. Be sure the wiring harness on the trailer is
taped or strapped to the trailer’s frame rail and leave
it
loose enough so the wiring doesn’t bend or break, but
not
so loose that it drags on the ground. The eight-wire
harness must be routed out of your vehicle between the
rear door and the floor, with enough of the harness left
on both sides so that the trailer or the body won’t pull it. If
you do
not have the optional trailering package, your
vehicle will
still have a trailering harness. The harness is
located near the passenger’s side rear wheel well. It
consists
of six wires that may be used by after-market
trailer hitch installers.
The technician can use the
following color code chart when connecting
the wiring
harness
to your trailer.
Brown: Rear lamps.
0 Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
White (Heavy Gage): Ground.
0 Light Green: Back-up lamps.
0 White (Light Gage): Center High-Mounted
Stoplamp.
Blue: Auxiliary circuit (eight-wire harness only).
0 Orange: Fused auxiliary (eight-wire harness only).
Store the harness
in its original place. Wrap the harness
together and tie
it neatly so it won’t be damaged.
