New Vehicle Limited Warranty 11
Damage Due to Contaminated or
Poor Quality Fuel
Poor fuel quality or incorrect fuel
may cause driveability problems
such as hesitation, lack of power,
stall, or no start. It may also render
gauges inoperable or degrade
functionality for components such
as spark plugs, oxygen sensors,
and the catalytic converter. Damage
from poor fuel quality, water
contamination, incorrect diesel fuel
or gasoline may not be covered.
It is recommended that gasoline
meet specifications which were
developed by automobile
manufacturers around the world
and contained in the World-Wide
Fuel Charter which is available
from the Alliance of Automobile
Manufacturers at
www.autoalliance.org/
fuel_charter.htm. Gasoline meeting
these specifications could provide
improved driveability and emission
control system performance
compared to other gasoline.Please refer to your Owner Manual
under
“Fuel” , for additional
recommendations, including the use
of TOP TIER Detergent Gasoline.
Additional information can also be
found at: www.toptiergas.com/
index.html.
Damage Due to Impact, Use,
or the Environment
Windshield or glass cracks, chips or
scratches due to impact are not
covered. Windshield cracks will be
covered for the first 12 months,

defects in material or workmanship.
Lights, lens, mirrors, paint, grill,
moldings and trim are not covered
for cracks, chips, scratches, dents,
dings and punctures or tears as a
result of impact with other objects or
road hazards. In addition, cracks,

Things to Know About the New Vehicle Limited Warranty 13
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 which may be
new, remanufactured, reconditioned,
or repaired, depending on the
component involved.
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, tape 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 Buick Customer
Assistance Center. The toll-free
telephone numbers are listed under
Customer Assistance Offices on
page 34.
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.
GM 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
paint or appearance concerns,
advise your dealer as soon as
