diesel engine vehicles. In any case,
the warranty with the broadest
coverage applies.
This warranty applies if your vehicle
meets both of the following
requirements:

Vehicles Subject to California
Exhaust Emission Standards)
The California Air Resources Board
and General Motors are pleased to
explain the emission control system
warranty on your vehicle. In
California, new motor vehicles must
be designed, built, and equipped to
meet the State's stringent anti-smog
standards. GM must warrant the
emission control system on your
vehicle for the periods of time and
mileage listed provided there has
been no abuse, neglect, or improper
maintenance of your vehicle. Your
vehicle's emission control system
may include parts such as the fuel
injection system, ignition system,
catalytic converter, and engine
computer. Also included are hoses,
belts, connectors, and other
emission related assemblies.
Where a warrantable condition
exists, GM will repair your vehicle at
no cost to you including diagnosis,
parts, and labor.

22 Emission Control Systems Warranty
* PZEV Hybrid Batteries are
covered for 10 years or
150,000 miles, whichever comes
first.
Any authorized Buick dealer will, as
necessary under these warranties,
replace, repair, or adjust to GM
specifications any genuine GM parts
that affect emissions.
The applicable warranty period shall
begin on the date the vehicle is
delivered to the first retail purchaser
or, if the vehicle is first placed in
service as a demonstrator or
company vehicle prior to sale at
retail, on the date the vehicle is
placed in such service.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, or modifications not
approved by GM.
If you have any questions regarding
your rights and responsibilities
under these warranties, you should
contact the Customer Assistance
Center at 1-800-222-1020 or, in

Emission Warranty Parts List 27
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
their manufacturer 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 an emergency
situation when a warranted part or a
warranty station is not reasonably
available to the vehicle owner.
In an emergency, where an
authorized dealer is not reasonably
available, repairs may be performed
at any available service
establishment or by the owner,
using any replacement part. Buick
will consider reimbursement for the expense incurred, including
diagnosis, not to exceed the
manufacturer's suggested retail
price for all warranted parts
replaced and labor charges based
on Buick'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 an emergency. Retain
receipts and failed parts in order to
receive compensation for warranty
repairs reimbursable due to an
emergency.
If, in an emergency situation, it is
necessary to have repairs
performed by other than a Buick
dealer and you believe the repairs
are covered by emission warranties,
take the replaced parts and your
receipt to a Buick dealer for
reimbursement consideration. This
applies to both the Federal
Emission Defect Warranty and
Federal Emission Performance
Warranty.

28 Emission Warranty Parts List
Receipts and records covering the
performance of regular maintenance
or emergency repairs should be
retained in the event questions arise
concerning maintenance. 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 Buick
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
Buick 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, refer to
the
Customer Satisfaction
Procedure on page 29. For further information or to report
violations of the Emission Control
System Warranty, you may contact
