PONTIAC FIREBIRD 1996 Owners Manual

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.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
I , conditions on a specified government test course. For
example,
a tire graded 150 would wear one and a half
(1 112) times as well on the government course as a tire
graded 100. The relative performance
of tires depends upon
the actual conditions of their use, however,
and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction -- A, B, C
The traction grades, from highest to lowest, are A, B, and
C, and they represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction,performance.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature -- A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled co’nditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the
material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performame
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109.

ProCarManuals.com

Grades B and A represent higher levels of performance
on the laboratory test wheel than the minimum required
by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have your wheels
aIigned again. However,
if you notice unusual tire wear
or your vehicle pulling one way or the other, the
alignment may need to be reset. If you notice your
vehicle vibrating when driving on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some aluminum wheels, which
can sometimes be repaired). See your
Pontiac dealer if any of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have
the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure to have
the right wheel, wheel bolts and wheel nuts for your
Pontiac model.
Using the wrong replacement wheels, wheel bolts
or wheel nuts
on your vehicle can be dangerous.
It could affect the braking and handling of your vehicle, make your tires lose air and make you
lose control.
You could have a collision in which
you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts
for
replacement.

Tire Chains
NOTICE:
The wrong wheel can also cause problems with
bearing life,
brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire
or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.
Used Replacement Wheels
Putting a used wheel on your vehicle
is
dangerous. You can’t know how it’s been used or
how many miles
it’s been driven. It could fail
suddenly and cause an accident.
Hf you have to
replace a wheel, use a new GM original
equipment wheel.
NOTICE:
If your Pontiac has P235/55R16, P245/50ZRl6 or
P275/40ZR17 size tires, don’t use tire chains.
They can damage
your vehicle.
If you have other tires, use tire chains only where
legal
and only when you must. Use only SAE Class
“S” type chains that are the proper size for your
tires. Install them on the rear tires and tighten
them as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them.
If’ the contact continues, slow down until it
stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.

Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous
if you breathe their fumes in a closed space.
When you use anything from a container to clean your
Pontiac, be sure
to follow the manufacturer’s warnings
and instructions. And always open your doors or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:
. Gasoline
Benzene
Naphtha
0 Carbon Tetrachloride
Acetone
0 Paint Thinner
Turpentine
0 Lacquer Thinner
0 Nail Polish Remover
They can all be hazardous -- some more than
others
-- and they can all damage your vehicle, too. Don’t use any of these unless this manual says you can.
In many uses, these will damage your vehicle:
0 Alcohol
Laundry Soap
Bleach
0 Reducing Agents
Cleaning the Inside of Your Pontiac
Use a vacuum cleaner often to get rid
of dust and loose
dirt. Wipe vinyl or leather with a clean, damp cloth.
Your Pontiac dealer has two
GM cleaners, a
solvent-type spot lifter and
a foam-type powdered
cleaner. They will clean normal spots and stains very well.
Do not use them on vinyl or leather.
Here are some cleaning tips:
0 Always read the instructions on the cleaner label.
0 Clean up stains as soon as you can -- before they set.
0 Use a clean cloth or sponge, and change to a clean area
often. A
soft brush may be used if stains are stubborn.
Use solvent-type cleaners in a well-ventilated area
0 If a ring forms after spot cleaning, clean the entire
only.
If you use them, don’t
saturate the stained area.

spots and stains will clean off better with just
water and mild soap.
If you need.to use a solvent:
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure and clean cloths (preferab’ly cheesecloth). Cleaning should start at
the outside of
the stain, “feathering” toward the center. Keep
changing
to a clean section of the cloth.
When you clean a stain from fabric, im.mediately
dry the area with a blow dryer to help prevent a
cleaning ring.

Cleaning the Outside of Your Pontiac
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep
it clean by washing it often with lukewarm or cold water.
’- Don’t wash your vehicle in the direct rays of the sun.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish or car washing (mild detergent) soaps.
Don’t use cleaning agents that
are petroleum based, or
that contain acid
or abrasives. All cleaning agents
should be flushed promptly and not allowed to
dry on
the surface, or they could stain. Dry the finish with
a
soft, clean chamois or a 100% cotton towel to avoid
surface scratches and water spotting.
High pressure car washes
may cause water to enter
your vehicle.
Finish Care
Occasional waxing or mild polishing of your Pontiac by
hand may be necessary to remove residue from
the paint
finish. You can get GM-approved cleaning products
from your dealer.
(See “Appearance Care and Materials”
in the Index.)
Your Pontiac has a “basecoaYclearcoat” paint finish.
The clearcoat gives more depth and gloss to the
colored basecoat. Always use waxes and polishes
that
are non-abrasive and made for a basecoatklearcoat
paint finish.
I NOTICE:
Machine compounding or aggressive polishing on
a basecoatklearcoat paint fbish may
dull the
finish
or leave swirl marks.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar,
tree sap, bird
droppings, chemicals
from industrial chimneys, etc., can
damage your vehicle’s
finish if they remain on painted
surfaces. Wash the vehicle as soon as possible.
If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces
are subject to aging, weather
and chemical fallout that can take their toll over a period
of years. You can help to beep the paint finish looking
new by keeping your Pontiac garaged or covered
whenever possible.

Cleaning Your Convertible Top
Your convertible top should be cleaned often. If you use
an automatic car wash, use one with water jets and
hanging cloths.
When you hand wash the top, do it in partial shade. Use
a
mild soap, lukewarm water and a soft sponge. A
chamois or cloth may leave lint on the top, and a brush
can chafe the threads in the top fabric. Don’t use
detergents, harsh cleaners, solvents or bleaching agents.
When you clean the top, put one hand under it to
support it. Wet the entire vehicle and wash the top
evenly to avoid spots or rings. Let the soap remain
on
the fabric for a few minutes. When the top is really dirty,
use a mild foam-type cleaner. Thoroughly rinse the
entire vehicle, then let the top
dry in direct sunlight.
To protect the convertible top:
0 After you wash the vehicle, make sure the top is

it could leave streaks.
Aluminum Wheels (If So Equipped)
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel. A wax
may then be applied.
The surface of these wheels is similar to the painted
surface of your car. Don’t use strong soaps, chemicals,
abrasive polishes, abrasive cleaners or abrasive cleaning
brushes on them because you could damage the surface.
Don’t take your vehicle through an automatic car wash
that has s.ilicon carbide tire cleaning brushes. These
brushes can also damage the surface of these wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
NOTICE:
When applying a tire dressing always take care
to wipe
off any overspray or splash from all
painted surfaces on the body or wheels
of the
vehicle. Petroleum-based products
may damq~e
the paint finish.
