Power Steering Fluid
How To Check Power Steering Fluid
Unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten
it. Then remove
the cap again and look at the fluid level on the dipstick.
When the engine compartment is hot, the level
should be at the
“HOT” mark.
0 When the engine compartment is cool, the level
should be at the
“FULL COLD” mark.
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.

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.
I NOTICE:
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.
Brake Wear
Your Buick has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and go
or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal
firmly).
I NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.

Fiberglass Springs
NOTICE:
Don’t use corrosive or acidic cleaning agents,
engine degreasers, aluminum cleaning agents or
other harsh solvents to clean fiberglass springs;
they’ll damage the springs.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect
in the paint job causes this, Buick
will repair,
at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever comes first.

Protection

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.
