How heavy can a trailer safely be?
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.
The following chart shows how much your trailer can
weigh, based upon your vehicle model and options.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total or gross
weight of your vehicle. The Gross Vehicle Weight
(GVW) 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 add the tongue load to the GVW because your
vehicle will be carrying that weight, too. See “Loading
Your Vehicle” in the Index for more information about
your vehicle’s maximum load capacity.

Downloaded from www.Manualslib.com manuals search engine 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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and
a heavy-duty turn signal flasher (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 will also flash, telling other
drivers you’re about to turn, 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.
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. On
a long uphill grade, shift down and reduce your
speed
to around 45 mph (70 kmh) to reduce the
possibility of engine and transmission overheating.
4-48

Downloaded from www.Manualslib.com manuals search engine If you have an automatic transmission, you should use
DRIVE
(D) when towing a trailer. Operating your
vehicle in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life
of your
transmission. Or, if
you have a manual transmission,
it’s better not to use
FIFTH (5) gear, just drive in
FOURTH
(4) gear (or, as you need to, a lower gear).
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) (or the
manual transmission out
of gear and the parking brake
applied) for a few minutes before turning the engine
off.
If you do get the overheat warning, see “Engine
Overheating” in the Index.
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.
2.
3.
4.
5.
6.
Apply your regular brakes, but don’t shift into
PARK
(P) yet, or into gear for a manual
transmission. Then turn your wheels into the curb if
facing downhill or into traffic if facing uphill.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your
parking brake, and then shift into PARK (P), or
REVERSE
(R) for a manual transmission.
If
you have a four-wheel-drive vehicle with a
manual transfer case shift lever, be sure the transfer
case is
in a drive gear -- not in NEUTRAL (N).
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:
0 Start your engine;
0 Shift into a gear; and
0 R.elease the parking brake.

Downloaded from www.Manualslib.com manuals search engine Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle. See “Roadside Assistance”
in
the Index.
If your vehicle
has been changed since it was
factory-new by adding things like fog lamps, aero
skirting, or special tires and wheels, these instructions
may not be correct.
Before you do anything, turn
on the hazard
warning flashers.
When you call, tell the towing service:
Whether your vehicle has rear-wheel drive,
four-wheel drive or all-wheel drive.
The make, model and year of your vehicle.
Whether you can move the shift lever for the
transmission and
shift the transfer case, if you
have one.
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know
that this manual contains these towing
instructions. The operator may want to see them.
5-7

Downloaded from www.Manualslib.com manuals search engine When your vehicle is being towed, have the ignition key
turned to 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
should be in
NEUTRAL (N) and the transfer case, if you
have one, should be in 2HI. The parking brake should
be released.
If your vehicle has a floor-mounted shifter and no
electrical power, the electrical solenoid lock must be
overridden to shift from PARK
(P) to NEUTRAL (N).
Follow these steps:
1. Push the base of the shift lever boot forward with
your thumb.
2. Lift the boot and find the white solenoid lever.
3. Move the solenoid lever
toward the driver’s side
to unlock
it.
4. While holding the solenoid lever in the unlock
position, press
the shift lever button and shift into
NEUTRAL
(N).
5. Release the solenoid lever and snap the boot back
into place.
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.

Downloaded from www.Manualslib.com manuals search engine If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires 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:
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, and then gently brake to
a stop well out
of the traffic lane.
H 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 a tire goes flat, the
next part shows how to use your
jacking equipment to change
a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place.
Turn on your hazard
warning flashers.
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 firmly.
2. Put an automatic transmission shift
lever in PARK
(P) or shift a manual
transmission
to FIRST (1) or
REVERSE (R).
3. Thrn off the engine.
4. Put the wheel blocks at the front and
rear of the tire farthest away from the
one being changed. That would
be the
tire on the other side of the vehicle, at
the opposite end.

Downloaded from www.Manualslib.com manuals search engine To remove the
underbody-mounted spare,
insert the chisel end of the
wheel wrench,
on an angle,
into the hole
in the rear
bumper. Be sure the chisel
end
of the wheel wrench
connects into the hoist shaft.
Turn the wheel wrench to the left to lower the spare tire.
Keep turning the wheel wrench until the spare tire can
be pulled
out from under the vehicle.
When the tire
has been completely lowered, tilt the
retainer
at the end of the cable and pull it through the
wheel opening.
Pull the tire out from under the vehicle.
I NOTICE:
- ~~
To help avoid vehicle damage, do not drive the
vehicle before the cable
is properly stored.
If you have an inside-mounted spare tire, the tire must
be removed
in order to have access to the jack storage.
