Inspection
WHAT SHOULD BE DONE
Inspect the front and rear suspension
and steering system for damaged,
loose or missing parts, signs of wear,
or lack of lubrication. Inspect the
power steering lines and hoses for
proper hookup, binding,
leaks,
cracks, chafing, etc. Clean and then inspect the drive axle boot seals for
damage, tears
or leakage. Replace
seals if necessary.
Inspect the complete exhaust system. Inspect the body near the
exhaust system. Look for broken,
damaged, missing or out-of-position
parts as well as open seams, holes,
loose connections, or other
conditions which could cause a heat
build-up in the floor pan or could let
exhaust fumes into the vehicle. See
“Engine Exhaust” in the Index.
Inspect the throttle linkage for
interference or binding, and for
damaged
or missing parts. Replace
parts as needed.

chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment.
You may need to have
your brakes inspected more often
if
your driving habits or conditions
result in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also,
if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays
on or
comes on, something may be wrong
with the anti-lock brake system. See
“Anti-Lock Brake System Warning

Customer Satisfaction Procedure
Your satisfaction and goodwill are important to your
dealer and Buick. Normally,
any problems 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 problem with a member of
dealership management. Complaints can often 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 problem cannot
be resolved by the dealership without further help, contact the Buick Customer Assistance Center by
calling 1-800-521-7300. In Canada, contact GM
of
Canada Customer Assistance Center in Oshawa by
calling 1-800-263-3777 (English) or 1-800-263-7854
(French).
In Mexico, call 254-17-86. In Puerto Rico or
U.S. Virgin
Islands, call 1-809-763- 13
15. In all other overseas
locations, contact GM International Export Sales in
Canada by calling 1-4 16-644-4
1 12.
For prompt assistance, please have the following information available to give the Customer Assistance
Representative:
Your name, address, telephone number
0 Vehicle Identification Number (This is available
from
the vehicle registration or title, or the plate
attached to the left top of the instrument panel and
visible through
the windshield.)
Dealership name and location
0 Vehicle delivery date and present mileage
Nature of problem In order to give your inquiry prompt attention, please
call the toll-free number listed above. However, if you
wish to write Buick, write to Buick Motor Division, 902
E. Hamilton Avenue, Flint, MI 48550. A listing of all
Buick Zone Offices and offices outside the
U.S. which
can assist you can also be found in the warranty booklet.
When contacting Buick, please remember that your
problem
will likely be resolved in the dealership, using
the dealership’s facilities, equipment and personnel.
That is
why we suggest you follow Step One first if you
have a problem.
Customer Assistance for the Hearing
or Speech Impaired
To assist owners who have hearing difficulties, Buick
has installed special TDD (Telecommunication Devices
for the Deaf) equipment in its Customer Assistance
Center. Any hearing or speech impaired customer who
has access to
a TDD or a conventional teletypewriter
(TTY) can communicate
with Buick by dialing:
1-800-TD-BUICK (TDD users
in Canada can dial
1-800-263-3830.)
