When the ring is at the “AUTO" position and a low level of ambient light is detected by the rain/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 may 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.
Switching on/off
When the function is activated or deactivated, a message is displayed.
Malfunction
In the event of a malfunction of
the rain/
sunshine sensor, the vehicle’s lighting
comes on and this warning lamp is displayed in
the instrument panel, accompanied by an
audible signal and/or the display of a message.
Contact a CITROËN dealer or a qualified workshop.
Do not cover the rain/sunshine
sensor
located at the top centre of the
windscreen behind the interior rear view
mirror; the associated functions would no
longer be controlled.
In fog or snow, the rain/sunshine
sensor
may detect sufficient light. For this
reason, the lighting will not come on
automatically.
The inner surface of the
windscreen may
become misted up and affect the proper
operation of the rain/sunshine sensor.
In humid and cold weather, demist the
windscreen regularly.
