should have your brake system fixed, since a leak means
that sooner or later
your brakes won’t work well, or

So, it isn’t a good idea to “top off’

leak. If you add fluid when your linings are worn, then

Fuses and Circuit Breakers
The wiring circuits in your car are protected from short
circuits by a combination of fuses, circuit breakers, and
fusible thermal links in the wiring itself.. This greatly
reduces the chance of fires caused by electrical
problems.
Be sure to use the correct fuse if you need to replace
one.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one
of the correct
value. Just pick some feature
of your car that you can
get along without
- like the radio or cigarette lighter -
and use its fuse, if it is of the value you need. Replace it
as soon as you can.
There are two fuse block areas inside your vehicle. One is located on the left side of the console under a carpeted
panel cover. Remove the cover to access the fuses.

INSPECTION OR SERVICE
Brake System
Inspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake lines and hoses for proper
hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment. You may need to have
your brakes inspected more often if
your driving habits or conditions
result in frequent braking.
NOTE: A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also, if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays on or
comes
-on, something may be wrong
with the anti-lock brake system. See “Anti-Lock Brake System Warning
Light” in the Index.

Lubricants
