Brake Wear
Using the wrong fluid can badly damage
brake system parts. 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. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. 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 has front disc brakes and rear drum 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).
A CA, TION:
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE: I
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure
you
replace a bad fuse with a new one of the identical size
and rating.
There are three fuse blocks in your vehicle: the
Instrument Panel Fuse Block located under the
instrument panel, the Underhood Fuse Block located on
the passenger’s side engine compartment, and the Rear
Fuse Block located under the rear seat.
Instrument Panel Fuse Block
The right side fuse panel is located under the
instrument panel.
Remove the hush panel to reveal the fuses.
To remove
the panel, remove the three screws located along the
rear edge of the panel. Place the wide end
of the fuse
puller over the plastic end
of the fuse. Squeeze the ends
over the fuse and pull it out.
>pare fuses are located
in the empty slots shown on the
following chart. When finished, replace
the hush panel. Replace lamps,
connectors, and HVAC duct temperature sensors if they
were removed.
