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 of the chocks.
4. Stop and have someone pick up and store the chocks.
Main ~ mr ~ ce 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.
Trailer Wiring Harness
The eight-wire harness, if you have one, is stored under
your vehicle along the rear frame crossmember. It is
wrapped and bound with a plastic strap. The harness has
a 30-amp battery feed and no connector, and
you should
have a qualified electrical service person wire your
harness for
you. 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 doesn’t bend or
break, but not
so loose that it drags on the ground.
Store the harness in its original place. Wrap the harness
together and tie it neatly
so it won’t be damaged.
The five-wire harness, if you have one, is stored inside
the vehicle at
the passenger side rear corner, behind the
jack. This should be wired by a qualified electrical
service person.
It 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.
Store the harness in its original place. Wrap the harness
together and tie it neatly
so it won’t be damaged.

Downloaded from www.Manualslib.com manuals search engine If your vehicle has a 7.4L engine and air conditioning,
your vehicle will have
a auxiliary engine fan in addition
to the belt driven fan.
A CAUTION:
If your vehicle has air conditioning, the auxiliary
engine fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools
away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.
Before closing the hood, be sure all the filler caps are
on properly.
Then lift the hood to relieve pressure
on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop
to its retainer. Then just let the hood
down and close
it firmly.
Noise Control System
The following information relates to compliance with
Federal noise emission standards for vehicles with a
Gross Vehicle Weight Rating (GVWR) of more than
10,000
lbs. (4 536 kg). The Maintenance Schedule
booklet provides information on maintaining the noise
control system
to minimize degradation of the noise
emission control system during the life of your vehicle.
The noise control system warranty is given
in your
Warranty booklet.
These standards apply
only to vehicles sold in the
United States.

Downloaded from www.Manualslib.com manuals search engine Dual Tire Operation Buying New Tires
To
find out what kind and size of tires you need, look at
the Certificatioflire label.
When
the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel nut torque
after
100, 1,000 and 6,000 miles (160, 1 600 and
10 000 km) of driving. For proper torque, see “Wheel
,Nut Torque” in the Index.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically.
If you’re going to be doing a lot of driving on
high-crown roads, you can reduce tire wear by adding
5 psi (35 kPa) to the tire pressure in the outer tires. Be
sure to return to the recommended pressures when no
longer driving under those conditions. See “Changing a
Flat Tire” in the Index for more information. The tires installed on your
vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
11 you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
If you operate your vehicle with a tire that is
badly underinflated, the tire can overheat. An
overheated tire can lose air suddenly or catch
fire.
You or others could be injured. Be sure all
tires (including the spare) are properly inflated.

Downloaded from www.Manualslib.com manuals search engine I ' A CAUTION:
Mixing tires could cause you to lose control while
driving. If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires
of different sizes may also cause
damage to your vehicle. Be sure
to use the same
size and type tires on
all wheels.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies
only to vehicles sold in the United States.) The
grades are molded on the sidewalls
of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply
to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or
to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect
to these
grades,
they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.

Use only mild soap and water to clean the top surfaces
'of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.
Care of Safety Belts
Keep belts clean and dry.
I A CAUTION:
Do not bleach or dye safety belts. If you do, it
might not be able to provide adequate protection.
~ may severely weaken them. In a crash, they
~ Clean safety belts only with mild soap and
1 lukewarm water.
Glass
Glass should be cleaned often. GM Glass Cleaner
(GM Part No. 1050427) or a liquid household glass
cleaner will remove normal tobacco smoke and
dust films.
Don't use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later.
If
abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
