3. Record the distance from the
ground to the aim dot on the
low-beam headlamp.
4. At a 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.
Do not place it directly on
the headlamp. 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.
The adjustment screw can be
turned with a 6 mm socket
wrench.
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.
