To adjust the vertical aim, do the
following:
1. Open the hood. SeeHood
on
page 9‑5for more information.
2. Locate the aim dot on the lens of the low‐beam headlamp.
3. Measure the distance from the ground to the aim dot on the
low‐beam headlamp. Record the
distance.
4. At the wall, measure from the
ground upward (A) to the
recorded distance from
Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall the width of the
vehicle at the height of the mark
in Step 4. Notice:
Do not cover a headlamp
to improve beam cut-off when
aiming. Covering a headlamp may
cause excessive heat build-up
which may cause damage to the
headlamp.
6. Turn on the low-beam
headlamps and place a piece of
cardboard or equivalent in front
of the headlamp not being
adjusted. This allows only the
beam of light from the headlamp
being adjusted to be seen on the
flat surface.

aimed to the horizontal tape
line. Turn it clockwise or
counterclockwise to raise or
lower the angle of the beam.

Electrical System
Fuses
The wiring circuits in the vehicle
are protected from short circuits by
fuses. 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
to replace a bad fuse with a new
one of the identical size and rating.
There are two fuse blocks in the
vehicle: one in the engine
compartment and one in the
instrument panel.
There is a fuse puller located in the
engine compartment fuse block.
See Engine Compartment Fuse
Block
on page 9‑39. It can be used
to easily remove fuses from the fuse
block.
