Automatic Illumination Of Headlamps - CITROËN C4 Handbook

Automatic illumination of
headlamps
The sidelamps and dipped beam headlamps
are switched on automatically, without any
action on the part of the driver, when a low level
of external light is detected or in certain cases
of activation of the windscreen wipers.
As soon as the brightness returns to an
adequate level or after the windscreen wipers
are switched off, these lamps are switched off
automatically and the daytime running lamps
come on.
Activation
F Turn ring A to the "AUTO" position. The
activation of the function is confirmed by
the display of a message.
Deactivation
F Turn ring A to a position other than
"AUTO". The deactivation of the function is
confirmed by the display of a message.
Lighting and visibility
Operating fault
In the event of a fault with the
sunshine sensor, the lighting come
on, this warning lamp is displayed
on the instrument panel and/or a
message appears in the screen,
accompanied by an audible signal.

workshop workshop.
In fog or snow, the sunshine sensor
may detect sufficient light. Therefore,
the lighting will not come on
automatically.

behind the rear view mirror; the
associated functions would no longer
be controlled.
