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 something
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.
7. Locate the vertical headlamp
aiming screws, which are under
the hood near each headlamp
assembly.

8. Turn the vertical aiming screw
until the headlamp beam
is aimed to the horizontal
tape line. Turn it clockwise or
counterclockwise to raise or
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
left (A) shows the correct
headlamp aim. The lamp
on the right (B) shows the
incorrect headlamp aim.
10. Repeat Steps 7 through 9 for
the opposite headlamp.
