Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to I3 000 km). Any time you notice unusual
wear, rotate your tires as
soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When
It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation is to achieve more
lrniform wear for all tires on the vehicle. The first
rotation is the most important. See ”Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your
tires, always use the correct rotation
pattern shown here.
If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque’‘ in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel
to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off. (See
“Changing a Flat Tire” in the Index.)

Fi nish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal
will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired
with touch-up
materials available from your retailer or other service
outlets. Larger areas of
finish damage can be col-rect.ed
in your retailer’s body and paint shop.
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 retailer or an underbody car washing system can
do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can
fill upon and
attack painted surfaces 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.

Your Vehicle and the EnvironmcC
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition, but also helps the
environment.
All recommended 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 from your vehicle. To help protect our
environment. 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 retailer’s service department or another
qualified service center do these
jobs.
7-2
ProCarManuals.com

Performing maintenance 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. See “Service and Owner Publications“
in
the Index.
“Part B: Owner Checks and Services” tells you what
should be checked and when.
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 retailer’s service
department or another qualified service center
should perform.
“Part D: Recommended Fluids and Lubricants” lists
some recommended products to help keep your vehicle
properly maintained. These products,
or their
equivalents, should be used whether you do the work
yourself or have
it clone.
“Part E: Maintenance Record” provides a place lor
you to record the maintenance performed
on your
vehicle. Whenever any maintenance is perfornled, be
sure to write
it down in this part. This will help you
determine when your next maintenance
should be clone.
In acldition, 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 en-ands or
in many other ways.
Because of
all the different ways people use their
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 retailer.
This part tells you the maintenance services you should
have done and
when you should schedule them. If you
go to your retailer 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:
0 carry passengers and cargo within recommended
limits. You
will find these limits on your vehicle’s
Certification/Tire label. See “Loading Your Vehicle”
in the Index.
0 are driven on reasonable road surfaces within legal
driving limits.
0 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:
