Adaptive headlights: Introduction

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2010 BMW 535xi, 2010 BMW 535i, 2009 BMW 535xi, 2009 BMW 535i, and 2008 BMW 535xi. However, it is still accessible from the selected car via links, so may be relevant.

Adaptive headlights turns the bi-xenon headlights towards the inside of a bend when cornering. This improves illumination of the curve of the road. Visibility is therefore improved.

When cornering, the driver is not looking into a "black hole" - instead, the adaptive headlights allow the driver to see the curve of the road.

E60, E61, E63, E64 up to 03/2005:

E70
The turning lights function is new on the E70 from the start of series production.

The turning lights give the area next to the roadway additional illumination when you are turning or cornering (driving in tight bends). They are also active when you park the vehicle.

Depending on the country concerned, the turning lights are activated when cornering.

NOTE: Components for adaptive headlight on E70, E81, E87, E90, E91, E92, E93
On the E81, E87, E90, E91, E92, E93, the adaptive headlights largely correspond to those on the E60, E61, E63, E64, E65 and E66:

E70, E81, E87, E90, E91, E92, E93 vehicles are equipped with a zero-position sensor.
On the E70, E81, E87, E90, E91, E92, E93, the FRM (footwell module) acts as control unit for exterior lighting. The footwell module contains the functions of the light module, AHL control unit and the general module (or body general module).
