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 oc-
curs, this warning lamp
is displayed on the
instrument 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.
When the dipped or main beam
headlamps are on, this function ena-
bles the light beam to follow the di-
rection of the road.

with the xenon headlamps only,
considerably improves the quality of
your lighting when cornering.

CHANGING A BULB
Procedure for replacing a faulty bulb
with a new bulb without the use of
any tools. Headlamps
Model with halogen headlamps

1. Dipped beams (H7 - 55 W)

2. Main beams (H1 - 55 W)

3. Sidelamps (H6 W - 6 W)

4. Direction indicators
(H21 - 21 W) A slight misting may appear on the
internal surface of the headlamp
glass in some climatic conditions
(e.g. low temperature or humidity);
this disappears after the lamps have
been on for a few minutes.

 Do not touch the bulb directly
with your fi ngers, use lint-free
cloths.
The headlamps are fi tted with poly-
carbonate glass with a protective
coating:

 do not clean them using a dry
or abrasive cloth, nor with a
detergent or solvent product,

 when using a high pressure
washer on persistent marks, do
not direct at the lamps or their
outlines for too long, so as not to
damage their coating and their
seals.
Changing a halogen bulb
should only be done after
the headlamp has been
switched off for a few minutes (risk
of serious burns).
It is imperative to use only anti-
ultraviolet (UV) type bulbs in order
not to damage the headlamp.
