considered a defect, and it may
occur before the vehicle warranty
expires. In this case, the owner is
responsible to purchase
replacement tires, or seek coverage
solely from the tire manufacturer.
For vehicles within the
bumper-to-bumper warranty
coverage, defective tires will be
replaced on a prorated adjustment
basis according to the following
mileage-based schedule:

12 Things to Know About the New Vehicle Limited Warranty
Warranty Repairs–
Component Exchanges
In the interest of customer
satisfaction, GM may offer
exchange service on some vehicle
components. This service is
intended to reduce the amount of
time your vehicle is not available for
use due to repairs. Components
used in exchange are service
replacement parts that may be new,
remanufactured, or refurbished.
Remanufactured parts meet GM
approved service part requirements
and are made from previously used
components in a process that
involves disassembly, inspection,
cleaning, update of software and
replacement of parts as appropriate,
testing and reassembly.
Refurbished parts meet GM
approved service part requirements
and are previously used parts that
are inspected, cleaned, tested, and
repackaged.
All exchange components used
meet GM standards and are
warranted the same as new components. Examples of the types
of components that might be
serviced in this fashion include:
engine and transmission
assemblies, instrument cluster
assemblies, radios, compact disc
players, batteries, and powertrain
control modules.
Warranty Repairs
–Recycled
Materials
Environmental Protection Agency
(EPA) guidelines and GM support
the capture, purification, and reuse
of automotive air conditioning
refrigerant gases and engine
coolant. As a result, any repairs GM
may make to your vehicle may
involve the installation of purified
reclaimed refrigerant and coolant.
Tire Service
Any authorized Buick or tire dealer
for your brand of tires can assist you
with tire service. If, after contacting
one of these dealers, you need
further assistance or you have
questions, contact the Buick
Customer Assistance Center. The toll-free telephone numbers are
listed under
Customer Assistance
Offices 031.
After-Manufacture
“Rustproofing”
Your vehicle was designed and built
to resist corrosion. Application of
additional rust-inhibiting materials is
neither necessary nor required
under the Sheet Metal Coverage.
Buick makes no recommendations
concerning the usefulness or value
of such products.
Application of after-manufacture
rustproofing products may create an
environment which reduces the
corrosion resistance built into your
vehicle. Repairs to correct damage
caused by such applications are not
covered under your New Vehicle
Limited Warranty.
Paint, Trim, and Appearance
Items
Defects in paint, trim, upholstery,
or other appearance items are
normally corrected during new
vehicle preparation. If you find any

2 yr/24,000 mile Federal Emission
Defect Warranty)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
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.
