Downloaded from www.Manualslib.com manuals search engine Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas
of finish damage can be corrected
in your dealer’s body and paint shop.
Magnesium Wheel Finish
NOTICE:
Improper paint repair or refinishing can cause
corrosion damage to a magnesium wheel. See
your dealer if a magnesium wheel needs paint
repair or refinishing.
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 car washing system can do
this for you.

Downloaded from www.Manualslib.com manuals search engine 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 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 dealer’s service department
or another quaMied 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 done.
“Part
E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, 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.

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
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.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
are driven on reasonable road surfaces within legal
driving limits.
use the recommended fuel. See “Fuel” in the Index.

Footnotes
The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emissions warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that
all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
* Your Corvette has an Engine Oil Life Monitor. This
monitor will show you when to change the oil
-- usually
between
3,000 miles (5 000 km) and 10,000 miles
(16 000 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles (5 000 km). Never drive your vehicle more
than
10,000 miles (1 6 000 km) or 12 months without
an oil change. Use engine oil meeting the GM
Standard
GM47 18M.
The Engine Oil Life Monitor won’t detect dust in the
oil. So if you drive in a dusty area, be sure to change
your oil every
3,000 miles (5 000 km) or sooner if the
CHANGE
OIL light comes on. Remember to reset the
Oil Life Monitor when the oil has been changed. For
more information, see “Engine Oil Life Monitor” in
the Index.
