Customer Information
Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Cadillac. 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.

CUSTOMER INFORMATION 377
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
Cadillac Customer Assistance Center
at 1-800–458–8006. In Canada, call
the Canadian Cadillac Customer Care
Centre at 1-888-446-2000.
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 Cadillac, 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 the 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:

This program is available in all

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

378 CUSTOMER INFORMATION
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.

eligibility in the Canadian Motor
Vehicle Arbitration Plan (CAMVAP),
