1 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
damage caused by electrical problems.
Some fuses are located
in a fuse block
in the glove box as shown.above. To
locate the fuse block, lift out the storage
bin inside the glove box. 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.

provides a place for you to record the
maintenance performed on your vehicle.
Whenever any maintenance is
performed, be sure to write it down in
this section. This will.help you

Conserving I1 oils of proper viscosity.
The “SH” or “SG” designation may
be shown alone or in combination
with others, such as “SH/CD,” “SH,
