Buick 2008 Automobile User Manual


 
To adjust the vertical aim on the headlamps:
1. Open the hood. See Hood 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 measure from the ground upward (A) to
the recorded distance from Step 3 and mark it.
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. Draw or tape a horizontal line (B) on the wall the
width of the vehicle at the height of the mark
in Step 4.
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
flat surface.
