Owner's Warranty Responsibilities
As the vehicle owner, you are
responsible for the performance of the
scheduled maintenance listed in your
owner manual. GM recommends that
you retain all maintenance receipts for
your vehicle, but GM cannot deny
warranty coverage solely for the lack
of receipts or for your failure to
ensure the performance of all
scheduled maintenance.You are responsible for presenting
your vehicle to a GM dealer selling
your vehicle line as soon as a problem
exists. The warranted repairs should
be completed in a reasonable amount
of time, not to exceed 30 days.
As the vehicle owner, you should also
be aware that GM may deny warranty
coverage if your vehicle or a part has
failed due to abuse, neglect, improper
or insufficient maintenance,
modifications not approved by GM,
or if the defect is not
emissions-related.
If you have any questions regarding
your rights and responsibilities under
these warranties, you should contact

Parts specified in your maintenance
schedule that require scheduled
replacement are covered up to their
first replacement interval or the
applicable emission warranty coverage
period, whichever comes first.
If failure of one of these parts results
in failure of another part, both will be
covered under the Emission Control
System Warranty.
For detailed information concerning
specific parts covered by these
emission control system warranties,
ask your dealer.Replacement Parts
The emission control systems of your
vehicle were designed, built, and
tested using genuine GM parts* and
the vehicle is certified as being in
conformity with applicable federal and
California emission requirements.
Accordingly, it is recommended that
any replacement parts used for
maintenance or for the repair of
emission control systems be new,
genuine GM parts.
The warranty obligations are not
dependent upon the use of any
particular brand of replacement parts.
The owner may elect to use
non-genuine GM parts for
replacement purposes. Use of
replacement parts which are not of
equivalent quality may impair the
effectiveness of emission control
systems.
If other than new, genuine GM parts
are used for maintenance
replacements or for the repair of parts
affecting emission control, the owner
should assure himself/herself that
such parts are warranted by theirmanufacturer to be equivalent to
genuine GM parts in performance and
durability.
*
“Genuine GM parts,” when used in
connection with GM vehicles, means
parts manufactured by or for GM,
designed for use on GM vehicles, and
distributed by any division or
subsidiary of GM.
Maintenance and Repairs
Maintenance and repairs can be
performed by any qualified service
outlet; however, warranty repairs must
be performed by an authorized dealer
except in a situation where the vehicle
owner is significantly inconvenienced
and a warranted part or a warranty
station is not reasonably available to
the vehicle owner.
In a situation where the vehicle owner
is significantly inconvenienced, and an
authorized dealer is not reasonably
available, repairs may be performed at
any available service establishment or
by the owner, using any replacement
part. Cadillac will consider
reimbursement for the expense
incurred, including diagnosis, not to
exceed the manufacturer's suggested

Cadillac Limited Warranty and Owner Assistance Information (GMNA-
Localizing-U.S.-11348300) - 2018 - crc - 2/6/17
26 EMISSION WARRANTY PARTS LIST
retail price for all warranted parts
replaced and labor charges based on
Cadillac's recommended time
allowance for the warranty repair and
the geographically appropriate labor
rate. A part not being available within
10 days or a repair not being
completed within 30 days constitutes
a significant inconvenience. Retain
receipts and failed parts in order to
receive compensation for warranty
repairs reimbursable due to these
situations.
If you are in a situation where you are
significantly inconvenienced and it is
necessary to have repairs performed
by other than a Cadillac dealer and
you believe the repairs are covered by
emission warranties, take the replaced
parts and your receipt to a Cadillac
dealer for reimbursement
consideration. This applies to both the
Federal Emission Defect Warranty and
Federal Emission Performance
Warranty.
Receipts and records covering the
performance of regular maintenance
or other repairs (such as those
outlined earlier) should be retained in
the event questions arise concerningmaintenance. These receipts and
records should be transferred to each
subsequent owner. GM will not deny
warranty coverage solely on the
absence of maintenance records.
However, GM may deny a warranty
claim if a failure to perform scheduled
maintenance resulted in the failure of
a warranty part.
Claims Procedure
As with the other warranties covered
in this booklet, take your vehicle to
any authorized Cadillac dealer facility
to obtain service under the emission
warranty. This should be done as soon
as possible after failing an
EPA-approved I/M test or a California
smog check test, or at any time you
suspect a defect in a part.
Those repairs qualifying under the
warranty will be performed by any
Cadillac dealer at no charge. Repairs
which do not qualify will be charged
to you. You will be notified as to
whether or not the repair qualifies
under the warranty within a
reasonable time, not to exceed 30 days
after receipt of the vehicle by the
dealer, or within the time period
required by local or state law.
The only exceptions would be if you
request or agree to an extension, or if
a delay results from events beyond the
control of your dealer or GM. If you
are not so notified, GM will provide
any required repairs at no charge.
In the event a warranty matter is not
handled to your satisfaction, see
Customer Satisfaction Procedure
028.
