Test Diagram for Low Beam

WARNING: This page is about a different car, the 2023 Volkswagen Atlas. However, it is still accessible from the selected car via links, so may be relevant.

Check the following:

-- The lowest part of the horizontal cut-off line must touch the test surface dividing line -1- when the low beams are on.

-- The bend point -2- between the left horizontal part and the right ascending part of the cut-off line should run vertically through the central point.

NOTE:

To make it easier to determine the bend point -2-, cover and uncover the left half of headlamp (as seen in driving direction), alternating a few 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 lie on the center mark -3-.
