Towing a Trailer
/I -
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. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section. Ask your
GM dealer for
advice and information about towing
a trailer
with your vehicle.

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 br’aking 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
.l
and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good dea
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.

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.
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, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help you find them qoickly.
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.
Trailer Wiring Harness
A seven-wire harness is stored under the rear of your
vehicle, between the frame rails. An electrical connector
will need to be added at the trailer end
of the harness, by
a qualified electrical technician. For additional trailer
wiring and towing information, please consult your
dealer. Securely attach the harness to the trailer, then
tape or strap it to your vehicle’s frame rail. Be
sure you
leave it loose enough so the wiring won’t bind or break
when turning with the trailer, but not
so loose that it
drags on the ground. Store’ the harness in its original
position. Wrap the harness together and tie it neatly
so it
won’t be damaged.
If you tow a trailer, your Center
High-Mounted Stoplamp (CHMSL) may not be
properly visible from behind.
You should select a trailer
with a CHMSL on
it or, if one is not available, have one
installed. See your GM dealer about how to connect
your vehicle’s wiring to a trailer CHMSL.

A vehicle can fall from a car’carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut
by sharp
edges underneath the towed vehicle.
When your vehicle is being towed, have the ignition key
in the off position. 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 transmission
and transfer case, if
you have one, should be in
NEUTRAL (N) and the parking brake released.
Don’t have your vehicle towed on the drive wheels
unless you must. If the vehicle must be towed
on the
drive wheels, be sure to follow the speed and distance
restrictions later in this section or your transmission will
be damaged. If these limitations must be exceeded, then
the drive wheels have
to be supported on a dolly.
