If the situation requires a change of headlamp
beam, the driver can take over at any time.
F Flashing the headlamps
again pauses the
function and the
system changes to
"automatic illumination
of headlamps" mode:
- if the AUTO indicator lamp was on in
green, the system changes to main
beam,
- if the AUTO indicator lamp was on in
blue, the system changes to dipped

The system may suffer interference or
not work correctly:
- under conditions of poor visibility
(for example, snowfall, heavy rain
or thick fog, ...),
- if the windscreen is dirty, misted or
obscured (by a sticker, ...) in front of
the camera,
- if the vehicle is facing highly
reflective signs.
The system is not able to detect:
- road users that do not have their
own lighting, such as pedestrians,
- road users whose lighting is
obscured, such as vehicles running
behind a safety barrier (on a
motorway, for example),
- road users at the top or bottom of
a steep slope, on twisty roads, on
crossroads.
