Headlamp Vertical Aiming
Notice:Horizontal aiming must be performed
before making any adjustments to the vertical aim.
Adjusting the vertical aim rst will result in an
incorrect headlamp aim.
1. Find the aim dot on the lens of the low-beam lamps.
2. Measure the distance from the ground to the aim
dot on each low-beam lamp. Record this distance.3. At the wall or other at surface, measure from the
ground upward the recorded distance from Step 2
and draw or tape a horizontal line the width of
the vehicle.
4. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being aimed. This should allow only
the beam of light from the headlamp being
aimed to be seen on the at surface.

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.
5. Turn the vertical aiming screw (V) until the
headlamp beam is aimed to the horizontal tape line.
The top edge of the cut-off should be positioned
at the bottom edge of the horizontal tape line.6. Repeat Steps 4 and 5 for the opposite headlamp.
