In the event of a breakdown
8Changing a bulb
The headlamps have polycarbonate lenses with a protective coating:
► do not clean them using a dry or
abrasive cloth, nor with a detergent or
solvent product,
► use a sponge and soapy water or a pH
neutral product,
► when using a high pressure washer on
persistent marks, do not keep the lance
directed towards the lamps or their edges for
too long, so as not to damage their protective
coating and seals.
Changing a bulb must only be done with
the ignition off and after the lamp has
been switched off for several minutes - Risk
of serious burns!
► Do not touch the bulb directly with your
fingers, use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
with the same type and specification.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the glass
of the headlamps and rear lamps is normal; it
disappears after the lamps have been on for a
few minutes.
Types of bulb
Various types of bulb are fitted on the vehicle. To
remove them:


Type A All-glass bulb: pull gently as it is fitted by
pressure.
Type B Bayonet bulb: press on the bulb then
turn it anti-clockwise.
Type C Cylindrical bulb: ease the contacts apart.
Type D Halogen bulb: release the retaining
spring from its housing.
