Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Adaptive Headlight-range Adjustment System
The adaptive headlight-range adjustment system is designed for driving through dips and over crests.
When driving through a dip the headlight beam throw is increased. The headlights are moved up a small amount. The driver can see further and oncoming vehicles are not dazzled. Obstacles on the roadway can therefore be detected earlier than with earlier headlight systems. This allows an early reaction to obstacles and initiation of any evasive action that may be required.
BMW makes an active contribution to safer driving with the adaptive headlight-range adjustment system.
When driving over a crest the beam pattern produced by the headlights is slightly lowered. Oncoming vehicles are not dazzled as much as with normal headlights. This contributes towards better road safety.

| 1 | Vehicle without the adaptive headlight-range adjustment system without raising or lowering the headlights |
| 2 | Vehicle with the adaptive headlight-range adjustment system, headlights slightly raised or lowered |
The red line shows the eye level of the oncoming traffic. The eye level is the location of the eyes when driving through a dip or over a crest.
