BMW 7 Series: Adjust Non-Dazzle High-Beam Headlight

WARNING: Danger of injury! Laser radiation at headlight adjustment aid.

Do not look into the beam!

NOTE: The high-beam headlight must be adjusted to prevent dazzle in the following cases:

• After removing and installing/replacing the headlight
• After customer complaint regarding low-beam behavior of headlights

Necessary preliminary work:

• Adjust HEADLIGHTS.

NOTE: There are two ways to adjust the high-beam headlight to prevent dazzle:

1. With electronic headlight adjuster "MAHA Lite 3".

2. With headlight adjustment aid.

The following operations describe the adjustment using the headlight adjustment aid:

Prerequisites for adjusting the high-beam headlight to prevent glare using the headlight adjustment aid:

• 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.

Fig. 1: Identifying Distance From Wall

NOTE: Headlight adjustment aid (2 299 574) and mountings (2) are labelled (see middle graphic):

• Headlight adjustment aid (2 299 574) has label A, B, C, D with the associated numbers 1-5.
• Mountings (2) are labelled A, B, C, D.

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
• Position rear mountings (A, B) with rods (1) on headlight adjustment aid (2 299 574) as follows:
  • Mounting (A) at A4
  • Mounting (B) at B4
• Attach laser (4) to the headlight adjustment aid (2 299 574). To switch on the laser (4), push up the flap in front of the laser (4).

Fig. 2: Preparing Headlight Adjustment Aid

Position headlight adjustment aid (2 299 574) at marked openings (1) in engine compartment as shown.

Align headlight adjustment aid (2 299 574) with longitudinally adjustable rods (2) using bubble level (3).

NOTE: The height of the headlight adjustment aid (2 299 574) has no influence on the setting.

Fig. 3: Positioning And Aligning Headlight Adjustment Aid

IMPORTANT: When the high-beam headlight is correctly set to prevent dazzle, the laser beam is at the height of the middle of the vehicle.

To do so, position tool (4) for example laterally to bead (3) as shown. Bead (3) represents the middle of the vehicle. Laser beam (1) must strike tool (4) at the point of intersection with bead (2).

If not, correct the alignment of the headlight adjustment aid (2 299 574).

Switch on ignition.

Switch on the low-beam headlight (high-beam headlight is switched on by the procedure).

Perform test procedure via path:

• Body
• Lights
• Adjust non-dazzle high-beam headlight

Fig. 4: Identifying Correct Laser Beam Position

The figure shows various photos after the headlight adjustment aid (2 299 574) is set up:

1. Laser beam
2. Low-beam headlight
3. High-beam headlight without procedure
4. High-beam headlight with procedure

IMPORTANT: Do not adjust the high-beam headlight to prevent dazzle without the procedure.

Fig. 5: Identifying Views Of Low/High Beam Headlights And Laser Beam After Headlight Adjustment Aid Is Set Up

1. Visibly mark the vertical line from the laser beam (3) on the wall using adhesive tape, for example.
2. Measure distance (A) from line (3) both to the left and right. Visibly mark distance (A) on the wall using adhesive tape, for example (1, 4).

   Vehicle with xenon headlights:
   Distance (A): 71 cm
   Distance (B): 142 cm
   Vehicle with LED headlights:
   Distance (A): 74 cm
   Distance (B): 148 cm

3. The light-dark boundary of the left high-beam headlight (2) without low-beams must be at marking (1).
4. The light-dark boundary of the right high-beam headlight (5) without low-beams must be at marking (4).

NOTE: The figure shows the correctly adjusted high-beam headlight.
