The headlamp aiming system has
been preset at the factory.
If the vehicle is damaged in an
accident, the aim of the headlamps
may be affected and adjustment
may be necessary.
It is recommended that a dealer
adjust the headlamps. To re-aim
the headlamps yourself, use the
following procedure.
The vehicle should be properly
prepared as follows. The vehicle:
.Should be placed so the
headlamps are 7.6 m (25 ft)
from a light colored wall.
.Must have all four tires on a
level surface which is level all
the way to the wall.
.Should be placed so it is
perpendicular to the wall or
other flat surface.
.Should not have any snow, ice,
or mud on it.
.Should be fully assembled and
all other work stopped while
headlamp aiming is being
performed.
.Should be normally loaded with
a full tank of fuel and one person
or 75 kg (160 lbs) sitting in the
driver's seat.
.Tires should be properly inflated.
Headlamp aiming is done with the
vehicle's low-beam headlamps.
The high-beam headlamps will be
correctly aimed if the low-beam
headlamps are aimed properly.

To adjust the vertical aim, do the
following:
1. Open the hood. SeeHood on
page 10‑5 for 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.

lower the angle of the beam.
9. Make sure that the light from the
headlamp is positioned at the
bottom edge of the horizontal
tape line. The lamp on the

headlamp aim. The lamp on the
right (B) shows the incorrect
headlamp aim.

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.
Replace a bad fuse with a new one
of the identical size and rating. If there is a problem on the road
and a fuse needs to be replaced,
the same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
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 10‑40. It can be used
to easily remove fuses from the fuse
block.
