Adjusting the Aim of a Headlight

ep3 dm 15.03.001

Note: Do not use power tools to adjust headlight aim. Doing so will strip or break the adjusting screw.

The adjusting screw is located on the bottom of the headlight assembly, accessible from inside the wheel well when the hood is closed. See Fig. .

  1. Remove the plug.
  2. Turn the adjusting screw clockwise to raise the beam of the headlight or counterclockwise to lower it.
  3. Adjust the beam until the center of the low-beam projection and the mark on the wall or screen is within the limits given in Table .
