Changing a bulb
The headlamps have polycarbonate
lenses with a protective coating:
F
d
o not clean them using a dr y or
abrasive cloth, nor with a detergent
or solvent product,
F

u
se a sponge and soapy water or a pH
neutral product,
F

w
hen 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.

the ignition off and after the headlamp has
been switched off for several minutes –
Risk of serious burns!

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 sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
