2006 BUICK LUCERNE low beam

To adjust the vertical aim, do the following:
1. Open the hood. SeeHood Release on page 5-11
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 or other at 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 at
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. Do not place directly
on the headlamp. This allows only the beam of
light from the headlamp being adjusted to be seen
on the at surface.

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
