Requirements for adjusting the Dynamic Light Spot headlight with headlight adjustment aid: 

• Comply with TEST PREREQUISITES FOR HEADLIGHT ADJUSTMENT .
• Position vehicle in front of vertical surface, e. g. a wall (1), as shown.
• Distance (A): 4 - 10 m
• Dim lighting is helpful.
• Have a tape measure and black adhesive tape (maximum width of 2 cm) ready.

Position of mounting (2) on headlight adjustment aid (2 299 574) is specified:

• Here by way of example mounting (B) at B4.

Prepare the headlight adjustment aid (2 299 574) as shown:

• Insert rods (1) into mountings (2) with identification (A, B) and clamp.
• Insert rods (3) into mountings (2) with identification (C, D) and clamp.
• Position front mountings (C, D) with rods (3) on headlight adjustment aid (2 299 574) as follows:
  • Mounting (C) at C5
  • Mounting (D) at D5

Switch the ignition on.

Perform test procedure via path:

• Body
• Lights
• Headlights for targeted illumination

Determining distances: 

Measure and note down distance (A) between middle of Dynamic Light Spot headlight (3) and floor (2).

Measure and note down distance (B) between laser beam (1) and floor (2) on the vehicle  .

Determine and note down distance (C):

Distance (C) = distance (B) - distance (A)

Attach adhesive tape markings (3, 4, 5 shown in black in the graphic) to the wall: 

1. Mark vertical laser beam (1) for example with adhesive tape (3) to wall (distance from floor (6) approx. 20 cm).
2. Measure distance (B) = 75 cm at top and bottom ends of adhesive tape (3) on both sides and mark. Connect the marks with adhesive tape (4).
3. Measure distance (C) from the previous operation from the horizontal laser beam (2) on both sides downwards and mark with adhesive tape (5).
