Automatic Illumination Of Headlamps - CITROËN DS 4 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 ambient light 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 in the screen.
deactivation
F Turn the ring to another position.
Deactivation of the function is accompanied
by the display of a message in the screen.
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 and/or a
message appears in the screen,
accompanied by an audible signal.
Contact a CITROËN dealer or a qualified
workshop.
Automatic guide-me-home
lighting
When the automatic illumination of headlamps
function is activated (lighting control stalk in the
"AUTO" position), under low ambient light the
dipped beam headlamps remain on when the
ignition is switched off.
Programming
Activation or deactivation, as well
as the duration of the guide-me-
home lighting, is set in the vehicle
configuration menu.
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 centre of the windscreen
behind the rear view mirror; the
associated functions would no longer
be controlled.
