Hitches Trailer Brakes
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:
If you use a step-bumper hitch, your bumper could
be damaged in sharp turns. Make sure you have
ample room when turning to avoid contact between
the trailer and the bumper.
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 and do not attach them to
the bumper. Always
leave
just enough slack so you can turn with your rig.
And, never allow safety chains to drag on the ground. If your
trailer weighs
more than 1,000 lbs. (450 kg)
loaded, then it needs its own brakes -- and they must be
adequate. Be sure to read and follow the instructions for
the trailer brakes
so you’ll be able to install, adjust qd
maintain them properly.
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 systems won’t work
well. You could even lose your brakes.
0 Will the trailer brake parts take 3,000 psi
(20 650 Ea) of pressure? If not, the trailer brake
system must not be used with your vehicle.
0 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 Following Distance
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. 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
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 green arrows on your instrument panel will
flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop. When towing
a trailer, the green arrow’s on your
instrument panel
will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may thlnk drrvers
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 km/h) to reduce the
possibility
of engine and transmission overheating.
If you are towing a trailer and you have a manual
transmission with FIFTH
(5) gear, you may prefer not to
use FIFTH
(5). Just drive in FOURTH (4) (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 ybur 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 mtil the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (PI, or REVERSE (R)
for a manual transmission.
PARK (P) yet, or into gear for a manual transmission.
5. If you have a four-wheel-drive vehicle, be sure
the transfer case is in a drive gear -- not in
NEUTRAL (N).
6. Release the regular brakes.
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set.
Your vehicle can roll,
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured.
To be sure your vehicle won’t move, even
when you’re on fairly level ground, use the steps
that follow.
If you have four-wheel drive and your transfer
case
is in NEUTRAL (N), your vehicle will be free
to roll,
even if your shift lever is in PARK (P). So,
be sure the transfer case is in a drive gear -- not
in NEUTRAL (N).

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
0 Release the parking brake.
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.
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, belts, 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.

Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level
in the
reservoir might go down. The first is that the brake fluid
goes down to
an acceptable level during normal brake
lining wear. When new linings are put in, the fluid level
goes back up.
The other reason is that fluid is leaking out
of the brake system.
If it is, you should have your brake

system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings
are worn, then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work ’is
done on the brake hydraulic system.
A CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is hot
enough.
You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.
Checking Brake Fluid
You can check the
brake fluid without taking
off the cap.
Just look at the windows on the brake fluid reservoir.
The fluid levels should be above
MIN, If they aren’t,
have your brake system checked
to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the levels
are above MIN and below the top of
each window.

What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and alvir-ays clean the brake fluid
reservoir cap before removing
it.
I d!L CAUTION:
1
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause
a
crash. Always use the proper brake fluid.
NOTICE:
e Using the wrong fluid can badly damage
brake system parts. For example, just
a few
drops of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See “Appearance Care” in
the Index.
