CITROËN C4 PICASSO Handbook page 215

Activation
F Put the lighting control stalk ring
in the "AUTO" position.
F In the Driving menu, select "Driving
assistance", then "Automatic headlamp
dip".
F Flash the headlamps
(going beyond the point
of resistance) to activate
the function.
Operation
Once the function is activated, the system
operates as follows:
If the ambient light level is sufficient and/or if
the traffic conditions do not allow illumination of
the main beam headlamps:
- dipped beam is
maintained, this indicator
lamp comes on in the
instrument panel.
If the ambient light level is very low and the
traffic conditions permit:
- main beam comes
on automatically: this
indicator lamp comes on in
the instrument panel.
Pause
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" and "Dipped beam"
indicator lamps are on, the system
changes to main beam,
- if the "AUTO" and "Main beam" indicator
lamps are on, the system changes to
dipped beam.
To reactivate the system, flash the headlamps
again.
Depending on the situation,
these indicator lamps
come on.
Deactivation
F In the Driving menu, select the "Driving
assistance" tab, then "Automatic
headlamp dip"; the system changes to
"automatic illumination headlamps" mode.
Lighting and visibility
The system may suffer interference or
not work correctly:
- under conditions of poor visibility
(falling snow, 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.
