Additional Maintenance
and Care
Your vehicle is an important investment and
caring for it properly may help to avoid
future costly repairs. To maintain vehicle
performance, additional maintenance
services may be required.
It is recommended that your dealer perform
these services —their trained dealer
technicians know your vehicle best. Your
dealer can also perform a thorough
assessment with a multi-point inspection to
recommend when your vehicle may need
attention.
The following list is intended to explain the
services and conditions to look for that may
indicate services are required.

Customer Satisfaction Procedure
Your satisfaction and goodwill are important
to your dealer and to Chevrolet. Normally,
any concerns with the sales transaction or
the operation of the vehicle will be resolved
by your dealer's sales or service
departments. Sometimes, however, despite
the best intentions of all concerned,
misunderstandings can occur. If your concern
has not been resolved to your satisfaction,
the following steps should be taken:
STEP ONE : Discuss your concern with a
member of dealership management.
Normally, concerns can be quickly resolved
at that level. If the matter has already been
reviewed with the sales, service, or parts
manager, contact the owner of your
dealership or the general manager.
STEP TWO : If after contacting a member of
dealership management, it appears your
concern cannot be resolved by your
dealership without further help, in the U.S.,
call the Chevrolet Customer Assistance
Center at 1-800-222-1020. In Canada, call
General Motors of Canada Customer Care
Centre at 1-800-263-3777 (English),
or 1-800-263-7854 (French).

Customer Information 309
We encourage you to call the toll-free
number in order to give your inquiry
prompt attention. Have the following
information available to give the Customer
Assistance representative:
.Vehicle Identification Number (VIN). This is
available from the vehicle registration or
title, or the plate at the top left of the
instrument panel and visible through the
windshield.
.Dealership name and location.
.Vehicle delivery date and present mileage.
When contacting Chevrolet, remember that
your concern will likely be resolved at a
dealer's facility. That is why we suggest
following Step One first.
STEP THREE —U.S. Owners : Both General
Motors and your dealer are committed to
making sure you are completely satisfied
with your new vehicle. However, if you
continue to remain unsatisfied after
following the procedure outlined in
Steps One and Two, you can file with the
Better Business Bureau (BBB) Auto Line
Program to enforce your rights. The BBB Auto Line Program is an
out-of-court program administered by BBB
National Programs, Inc. to settle automotive
disputes regarding vehicle repairs or the
interpretation of the New Vehicle Limited
Warranty. Although you may be required to
resort to this informal dispute resolution
program prior to filing a court action, use of
the program is free of charge and your case
will generally be heard within 40 days.
If you do not agree with the decision given
in your case, you may reject it and proceed
with any other venue for relief available
to you.
You may contact the BBB Auto Line Program
using the toll-free telephone number or
write them at the following address:

dispute-handling-and-resolution/bbb-auto-lineThis program is available in all 50 states and
the District of Columbia. Eligibility is limited
by vehicle age, mileage, and other factors.
General Motors reserves the right to change
eligibility limitations and/or discontinue its
participation in this program.
STEP THREE
—Canadian Owners : In the
event that you do not feel your concerns
have been addressed after following the
procedure outlined in Steps One and Two,
General Motors of Canada Company wants
you to be aware of its participation in a
no-charge Mediation/Arbitration Program.
General Motors of Canada Company has
committed to binding arbitration of owner
disputes involving factory-related vehicle
service claims. The program provides for the
review of the facts involved by an impartial
third party arbiter, and may include an
informal hearing before the arbiter. The
program is designed so that the entire
dispute settlement process, from the time
you file your complaint to the final decision,
should be completed in about 70 days. We
believe our impartial program offers
advantages over courts in most jurisdictions
because it is informal, quick, and free of
charge.
