2006 Pontiac G6 Owner's 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. 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. 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. Passenger's Side Shown 7. Locate the vertical headlamp aiming screws, which are under the hood, on top of each headlamp assembly. 5-48
