1996 GMC SIERRA air condition

Dual Tire Operation
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, I 600 and IO 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.
A CAUTION:
I
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, if any) are properly inflated.
Buying New Tires
To find out what kind and size of tires you need, look at
the Certificntion/Tire label.
Tlze 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).
If 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.

Tempera 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 conditions
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 performance
which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. 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
aligned 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
GM dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on the underbody, If these are
not removed, accelerated corrosion (rust) can occur
on the underbody parts such as fuel lines, frame,
floor pan and exhaust system even though they have
corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed
in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody vehicle washing system
can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can
fdl upon and
attack painted surfxes
on your vehicle. This damage can
take two forms: blotchy, ringlet-shaped discolorations, and
small irregular dark spots etched into the paint surface.
Although
no defect in the paint job causes this, GM
will repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
This applies
only to materials manufactured and sold by
General Motors. Bodies, body conversions or equipment
not made or
sold by General Motors are not covered.

Protection
Plan
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition. but also helps the
environment.
All 1-ecommended maintenance procedures
are important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid
levels or the wrong
tire inflation can increase the level
of emissions fr6m your vehicle. To help protect our
environlnent, and to keep your vehicle in good
condition, please maintain your vehicle properly.

How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services’’ shows
what to
have done and how often. Some of these
services can be complex, so unless you are technically
qualified and have
the necessary equipment, you should
let
your dealer’s service department or another qualified
service center do these jobs.
Performing ma~ntenance worK on a vehicle can
be dangerous. In trying to do
some jobs, you can
be seriously injured.
Do your own maintenance
work only
if you have the required know-how
and the proper tools and equipment for the
job.
If you have any doubt, have a qualified technician do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications”
in the Index.
“Part B: Owner Checks and Services” tells you
what should be checked whenever you stop for fuel.
It
also explains what you can easily do to help keep your
vehicle
in good condition.
“Part C: Periodic Maintenance Inspections”
explains important inspections that your GM dealer’s
service department
or another qualified service center
should perform.
“Part D: Recommended Fluids and Lubricants”
lists some products GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself or have
it done.
“Part E: Maintenance Record” provides a place
for you to record the maintenance performed
on your
vehicle. Whenever any maintenance
is perf‘ormed, be
sure to write
it down in this part. This will help you
determine when your
next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may
be needed to qualify your vehicle for
warranty repairs.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle
in good working condition. But we don’t know
exactly how you’ll drive
it. You may drive very short
distances only a few times a week. Or
you may drive
long distances all the time
in very hot, dusty weather.
You may use your vehicle in making deliveries.
Or you may drive
it to work, to do errands or in
many other ways.
Because
of all the different ways people use their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than you’ll find
in the schedules in this section. So please read this
section and note how
you drive. If you have any
questions on
how to keep your vehicle in good
condition, see your GM dealer.
This part tells
you the maintenance services you should
have done and when
you should schedule them. If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine GM parts.
The proper fluids and lubricants to
use are listed in
Part D. Make sure whoever services your vehicle uses these.
All parts should be replaced and all necessary
repairs done before
you or anyone else drives the vehicle.
These schedules are for vehicles that:
carry passengers and cargo within recommended
limits. You will find these limits
on your vehicle’s
CertificatiodTire label. See “Loading Your Vehicle”
in the Index.
are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in the recommended manner. See
”Off-Road Driving With Your Four-Wheel-Drive
Vehicle”
in the Index.
use the recommended fuel. See “Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle.
Here’s how to decide which
schedule
to follow:
Gasoline engine vehicles and diesel engine vehicles
have different maintenance requirements.
If you have a
diesel engine, follow a schedule designated
for diesel
engine vehicles only.
See the Diesel Engine Supplement for diesel engine
maintenance schedules.
