• The bend point -2- between the left horizontal part and the right rising part of the cut-off line must run vertically through the central mark -3-. The bright core of the light beam must be to the right of the vertical.

-- To determine the bend point -2- more easily, cover and uncover the left half of the headlamp (seen in direction of travel) several times. Then check the low beam again.

• After adjusting the low beam according to the instructions, the center of the high beam light beam must be on the central marking -3-.

-- Turn the adjusting screw -3- to adjust laterally.

The side adjustment bolt -3- must be secured with the plugs after the adjustment is made on USA vehicles. Refer to the Parts Information for the correct plugs.
