Operating fault
In the event of a fault with the brightness sensor, the lighting come on, this warning lamp is displayed on the instrument panel and/or a message appears on the multifunction screen, accompanied by an audible signal. Consult a CITROËN dealer.
In fog or snow, the brightness sensor may detect suffi cient light. Therefore, the lighting will not come on automatically.
Do not cover the brightness sensor, coupled with the rain sensor and located in the centre of the windscreen behind the interior mirror; the associated functions would no longer be controlled.
