4. At the wall or other flat surface, 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 or flat surface 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.
