Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal
of important components can significantly
affect the quality of the-air we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level
of emissions from your vehicle. To help protect
our environment, and to help keep your vehicle in good
condition, please maintain your vehicle properly.
How This Part is Organized
The remainder of this part is divided into five sections:
“Section A: Scheduled Maintenance Services” shows
what to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
A CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to
do some jobs, you can
be seriously injured.
Do your own maintenance
work only
if you have the required know-how and
the proper tools and equipment for the job.
If you
have any doubt, have a qualified technician
do
the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information GM publishes. You will find a list of
publications and how to get. them in this manual. See
“Service Publications” in the Index.
“Section B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily do to help keep your
vehicle in good condition.
“Section
C: Periodic Maintenance Inspections” explains
important inspections that your Buick dealer’s service
department or another qualified service center should
perform.

Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the~radiator and air
conditioning condenser. Wash the pressure cap and
neck.
To help ensure proper operation, we recommend a
pressure test
of both the cooling system and the
pressure cap.
7. Transaxle Service -- Change both the fluid and
filter every
15,000 miles (25 000 km) if the vehicle
is mainly driven under one or more of these
conditions:
0 In heavy city traffic where the outside
temperature regularly reaches
90 F (32 C) or
higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing. (With some
models, you shouldn’t ever tow a trailer. See
“Towing a Trailer” in the Index.)
Uses such as found in taxi, police car or delivery
service. If you
do’ not use your vehicle under any of these
conditions, change both the fluid and filter every
100,000 miles (160 000 km).
8. Spark Plug Replacement* -- Replace spark plugs
with the proper type. See “Specifications Chart” in
the Index.
9. Spark Plug Wire Inspection (3.3L Code N engine
only)*?
-- Inspect for burns, cracks or other
damage. Check the boot fit at the coils and at the
spark plugs. Replace wires as needed.
10. Air Cleaner Filter Replacement* -- Replace every
30,000 miles
(50 000 km) or more often under dusty
conditions. Ask your dealer for the proper
replacement intervals for your driving conditions.
11. Fuel Tank, Cap and Lines Inspection”? -- Inspect
fuel
tank, cap and lines (including fuel rails and
injection assembly) for damage or leaks. Inspect fuel
cap gasket for an even filler neck imprint or any
damage. Replace parts as needed. Periodic
replacement of the fuel filter is not required.
* An Emission Control Service.
The
U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section EMaintenance Record”.
