What to Add
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index.
NOTICE:
When adding power steering fluid or making a
complete fluid change, always use the proper
fluid. Failure to use the proper fluid can cause
leaks and damage hoses and seals.

should have your brake system fixed, since a leak means
that sooner or later your brakes won’t work well,
or
won’t work at all. So, it isn’t a good idea to “top off’
your brake fluid. Adding brake fluid won’t correct a
leak. If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake
linings. You should add (or remove) brake fluid, as
necessary, only when work
is done on the brake
hydraulic system.
When
your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light” in the Index.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing it.
NOTICE:
DOT-5 silicone brake fluid can damage
your vehicle. Don’t use
it.
a Don’t let someone put in the wrong kind of
fluid. For example,
just a few drops of
mineral-based
oil, such as engine oil, in
your brake system can damage brake
system parts
so badly that they’ll have to
be replaced.
Brake fluid can damage paint, so be careful
not to spill brake
fluid on your vehicle. If
,you do, wash it off immediately. See
“Appearance Care” in the Index.

your Buick dealer
for details.
Introduction
A Word About Maintenance
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it.
You may drive very short
distances only a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or you
may drive it to work, to do errands
or in many other
ways.
Because of all the different ways people use their GM
vehicles, maintenance needs vary.
You may even need
more frequent checks and replacements
than you will
find in the schedules in this part.
So please read this
part and note how you drive.
If you have any questions
on
how to keep your vehicle in good condition, see your
Buick dealer, the place many GM owners choose to
have their maintenance work done.
Your dealer can be
relied upon to use proper parts and practices.
