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.
STEP TWO : If after contacting a
member of dealership management, it
appears your concern cannot be
resolved by your dealership without

CUSTOMER INFORMATION 409
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
the Council of Better Business Bureaus
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:
