light GMC SIERRA 1996 Repair Manual

-
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 IO 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
conditions on
a specified government test course. For
example. a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire
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.
E at-aded 100. The relative performance of tires depends
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.

Using Foam-Type Cleaner T I ~. ~. .
1. Vacuum and brush the area to remove any loose
dirt.
2. Always clean a whole trim panel or section. Ma *
3. Mix Multi-Purpose Powdered Cleaner following
surrounding
trim along stitch or welt lines.
the directions on the container label.
4. Use suds only and apply with
a clean sponge.
5. Don’t saturate the material.
6. Don’t rub it roughly.
7. As soon as you’ve cleaned the section, use a sponge
to remove the suds.
8. Rinse the section with a clean, wet sponge.
9. Wipe off what’s left with a slightly damp paper
towel or cloth.
10. Then dry it immediately with a blow dryer.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some 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 (preferably
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, immediately
dry the area
with a blow dryer to help prevent a
cleaning ring.
Fabric Protection
Your vehicle has upholstery and carpet that has been
treated with Scotchgard’” Fabric Protector, a
3M
product. It protects fabrics by repelling oil and water,
which are the carriers
of most stains. Even with this
protection, you still need to clean your upholstery and
carpet often to keep
it looking new.
11. Wipe with a clean cloth.

on cleaning is available by calling

Fu ~ ~ s and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of
fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance
of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure
you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have a
spare fuse,
you can borrow one that has the same
amperage.
Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
Instrument Panel Fuse Block
The fuse block access door
is on the driver’s side edge
of the instrument panel. Pull
off the cover
to access the
fuse block.
You can remove fuses with a fuse extractor. The fuse
extractor
is mounted to the fuse block access door. To
remove fuses if you don’t have a fuse extractor, hold the
end of the fuse between your thumb and index finger
and
pull straight out.
