AUTOMATIC ADJUSTMENT OF THE XENON HEADLAMPS
In order to avoid causing a nuisance
to other road users, this system cor-
rects the height of the xenon head-
lamps beam automatically and when
stationary, in relation to the load in
the vehicle. If a malfunction occurs,
this warning lamp is
displayed on the in-
strument panel, ac-
companied by an audible signal and a
message on the multifunction screen.
The system then places your head-
lamps in the lowest position.
If a malfunction occurs, do not
touch the xenon bulbs. Contact a
CITROËN dealer.
DIRECTIONAL LIGHTING
When the dipped or main beam
headlamps are on, this function ena-
bles the light beam to follow the di-
rection of the road.
The use of this function, coupled
with the xenon headlamps only,
considerably improves the quality of
your lighting when cornering.
