10-30 Vehicle Care 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. This allows only the beam of light from the headlamp being adjusted to be seen on the flat surface. 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. 7. Locate the vertical headlamp adjusters, which are under the hood near each headlamp assembly. For the vehicle equipped with a base level lamp (halogen bulb), there will be one vertical headlamp adjuster (V1).
