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,

Buick regularly sends its dealers useful service bulletins
about Buick products. Buick monitors product
performance in the field. We then prepare bulletins for
servicing our products better. Now, you can get
these
bulletins too. Bulletins cover various subjects.
Some pertain to the
proper
use and care of your vehicle. Some describe
costly repairs. Others describe inexpensive repairs
which, if done on time with the latest parts, may avoid
future costly repairs. Some bulletins tell a technician
how
to repair a new or unexpected condition. Others
describe a quicker way to fix your vehicle. They can
help a technician service your vehicle better.
Most bulletins apply
to conditions affecting a small
number of cars or trucks. Your Buick dealer or a
qualified technician may have to determine if a specific
bulletin applies to your vehicle.
You can subscribe to all Buick bulletins. This way
you’ll
get them as they come out. You can wait a while and get
an index to the bulletins. You can also get individual
bulletins. However,
you’ll need the index to identify
them.
