Vehicles with incorrect position of the test pattern
Tip
When adjusting manually, it might be that not all of the contours of the HUD test picture can be positioned well on the Setting Device: VAS6430 . This is due to the tolerances in the HUD system and the distortion resulting from this. In this case, primarily the elements in the center area of the picture should be as well aligned as possible. Variances with the elements in the outer area of the picture are permitted.
