Automatic Illumination Of Headlamps - CITROËN C4 PICASSO Handbook

Automatic illumination of
headlamps
When a low level of ambient light is detected
by a sunshine sensor, the number plate lamps,
sidelamps and dipped beam headlamps are
switched on automatically, without any action
on the part of the driver. They can also come
on if rain is detected, at the same time as
automatic operation of the windscreen wipers.
As soon as the brightness returns to a
sufficient level or after the windscreen wipers
are switched off, the lamps are switched off
automatically.
Activation
F Turn the ring to the "AUTO" position. The
activation of the function is accompanied
by the display of a message.
Deactivation
F Turn the ring to another position.
Deactivation of the function is
accompanied by the display of a message.
Operating fault
In the event of a malfunction of the
sunshine sensor, the lighting comes
on, this warning lamp is displayed
in the instrument panel accompanied by an
audible signal and/or a message.
Contact a CITROËN dealer or a qualified
workshop.
In fog or snow, the sunshine sensor
may detect sufficient light. In this
case, the lighting will not come on
automatically.
Do not cover the sunshine sensor,
coupled with the rain sensor and
located in the top of the windscreen
behind the rear view mirror; the
associated functions would no longer
be controlled.
