When the engine compartment is
cool, the level should be at the
C
mark.
What to Add:
Refer to the Maintenance Schedule to
determine what kind of fluid to use. See
the
Index under Fluids G Lubricants.
When adding power steering fluid
or making a complete fluid change,
always use the proper fluid. Failure
to use the proper fluid can cause

Fuses & Circuit Breakers
The wiring circuits in your vehicle 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.
Some fuses are located in a fuse block
in the glove box as shown above.
To
locate the fuse block, pull down the
cover. See the diagram later in this
section.
Another set
of fuses is located in the
component center, under the
instrument panel.
Additional fuses are located in the
underhood electrical centers on the
right and left sides of the engine
compartment.
270
Spare fuses and a fuse puller are located
in the glove box fuse block cover.
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.
To identify and check fuses, refer to the
charts on the following pages. 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.
