Pontiac 2006 G6 - Manual (Page 316)

Headlamp aiming is done with the vehicle’s low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low beams are aimed properly.
To adjust the vertical aim, do the following:
1. Open the hood. See Hood Release on page 5-11
for more information.
2. Find the aim dot on the lens of the low-beam lamp.
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 flat surface, measure from the
ground upward the recorded distance from Step 3
and mark it.
5. Draw or tape a horizontal line the width of the
vehicle at the wall or other flat surface where it
was marked 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 aimed. This should allow only
the beam of light from the headlamp being
aimed to be seen on the flat surface.
7. Locate the vertical headlamp aiming screws, which
are under the hood, on top of each headlamp
assembly.
