Front Lamp Unit Alignment
With the horizontal centerline of the headlamp (1) transferred on the wall, measure down 76 mm (3 in). This line (6) will be the vertical aiming mark. Using the intersecting point (5) of the horizontal centerline (6) and the vertical centerline (2) for the left headlamp, adjust the headlamp unit horizontally and vertically so (5) is the intersecting point at lines (6 and 2). For the right headlamp unit, cover up the left headlamp and follow the same procedure but intersecting at (6 and 4).
- Turn the headlamps On and select the Low beams.
- The vertical alignment screw (2) is located on the top of the headlamp leveling motor (4).
- The horizontal alignment screw (2) is located next to and inboard of the headlamp leveling motor.
A properly aimed low beam headlamp will project a high intensity light pattern on the screen with the horizontal cut-off line aligned with the tape line 100 mm (3.94 in.) below the headlamp centerline. The intersection of the horizontal and 15 degree cut-off lines in the projected pattern should align to the intersection of the headlamp centerline vertical tape line and the tape line 100 mm (3.94 in.) below the headlamp horizontal centerline. The high beams on a vehicle with aero headlamps cannot be aligned. The high beam pattern should be correct when the low beams are aligned properly.
