Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to the
low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to the dealer
for service.

Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of fires 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.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without—like the radio or
cigarette lighter —and use its fuse,
if it is the correct amperage.
Replace it as soon as you can.
Engine Compartment
Fuse Block
The engine compartment fuse block
is located on the driver side of the
engine compartment. See Engine

page 10‑6 for more information
on location. To remove the cover, push in on the

To reinstall the cover, line up the tab
and push down on the cover until
