Cornering light function
The cornering light function improves the illumi‐
nation of the carriageway over a wide angle in
the turning direction, enabling better visibility on
tight bends, for example. It can be activated only
when the low beam is switched on.
The function is active in the following cases:
at speeds below 40 km/h when the turn sig‐
R
nal indicator is switched on or the steering
wheel is turned
at speeds between 40 km/h and 70 km/h
R
when the steering wheel is turned
Roundabout and intersection function: the
cornering light will be activated on both sides
based on an evaluation of the current GPS posi‐
tion of the vehicle. It will remain active until after
the vehicle has left the roundabout or the inter‐
section.
Motorway mode function
Motorway mode increases the range and bright‐
ness of the cone of light, enabling better visibil‐
ity.
The function is enabled if a motorway journey is
detected by:
the vehicle's speed
R

the multifunction camera

the GPS

The function will not be enabled in the following
cases:
at speeds below 80 km/h.

City lighting function
City lighting improves the illumination of road‐
sides within built-up areas using a broad distri‐
bution of light.
The function is active in the following cases:
at low speeds
R
in illuminated parts of built-up areas

Function of the off-road light
The off-road light improves illumination during
off-road driving. The low beam is distributed
symmetrically and across a wide angle. This
makes it easier to find your way when driving
off-road and to detect obstacles at an early
stage. The active headlamps function is deacti‐
vated during this time so that steering move‐
ments do not change the illumination.
