CHANGING A BULB


The headlamps are fi tted with
polycarbonate glass with a pro-
tective coating:


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



use a sponge and soapy wa-
ter or a pH neutral product,


when using a high pressure
washer on persistent marks,
do not keep the lance direct-
ed towards the lamps or their
edges for too long, so as not
to damage their protective
coating and seals.
Changing a bulb should only be
done after the headlamp has
been switched off for a few min-
utes (risk of serious burns).



Do not touch the bulb directly
with your fi ngers, use a lint-
free cloth.
It is imperative to use only anti-
ultraviolet (UV) type bulbs to
avoid damaging the headlamp.
Always replace a failed bulb with
a new bulb with the same type
and specifi cation.

Xenon bulbs (D1S-35W) must
be replaced by a CITROËN
dealer or a qualifi ed workshop.
