Customer Assistance and
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 your 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 the
dealership or the general manager.STEP TWO:If after contacting a member of
dealership management, it appears your concern
cannot be resolved by the dealership without
further help, in the United States, contact
the Cadillac Customer Assistance Center, 24 hours
a day, by calling 1-800-458-8006. In Canada,
contact the Canadian Cadillac Customer
Communication Centre by calling 1-888-446-2000.
We encourage you to call the toll-free number
in order to give your inquiry prompt attention.
Please have the following information available to
give the Customer Assistance Representative:
Vehicle Identication 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, please remember that
your concern will likely be resolved at a dealer’s
facility. That is why we suggest you follow
Step One rst if you have a concern.

STEP THREE (Canadian Owners):
General Motors Participation in the
Mediation/Arbitration Program
In the event that you do not feel your concerns
have been addressed after the following the
procedure outlined in Steps One and Two. General
Motors of Canada Limited wants you to be
aware of its participation in a no-charge
mediation/Arbitration program. General Motors of
Canada Limited 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 le
your complaint to the nal decision, should be
completed in approximately 70 days. We believe
our impartial program offers advantages over
courts in most jurisdictions because it is informal,
quick, and free of charge.For further information concerning eligibility in the
Canadian Motor Vehicle Arbitration Plan
(CAMVAP), call toll-free 1-800-207-0685.
