Chevrolet 2009 HHR, Owner'S Manual

Page: 323 / 450

To adjust the vertical aim:
1. Open the hood. See Hood Release on page 5-13
for more information.
2. Find 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.
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 directly on the
headlamp. This allows only the beam of light from
the headlamp being adjusted to be seen on the flat
surface.
