Downloaded from www.Manualslib.com manuals search engine “Section C: Periodic Maintenance
Inspections” explains important inspections that your Chevrolet dealer’s
service department or another qualified
service center should perform.
“Section
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.
“Section
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 section.
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.
Section A: Scheduled
Maintenance Services
Using Your Maintenance
Schedule
This section tells you the maintenance
services you should have done and
when you should schedule them. Your
Chevrolet dealer knows your vehicle best
and wants you to be happy with
it. 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.
These schedules are 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.

Chevrolet regularly sends its dealers
useful service bulletins about Chevrolet
products. Chevrolet monitors product performance
in the field. We then prepare
bulletins for servicing our products better.
Now, you can get these bulletins too.
Bulletins cover various subjects. Some
pertain to the proper use and care of your
vehicle. Some describe costly repairs.
Others describe inexpensive repairs
which, if done on time with the latest
parts, may avoid future costly repairs.
Some bulletins tell a technician how to
repair a new or unexpected condition. Others describe a quicker
way to fix your
vehicle. They can help a technician
service your vehicle better.
Most bulletins apply to conditions
affecting a small number of cars or trucks.
Your Chevrolet dealer or a qualified
technician may have to determine
if a
specific bulletin applies to your vehicle.
