Before changing any bulb, first turn off the
failed device.
Do not touch the glass part of the bulb with
your bare hands. The fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, reducing bulb life and
causing condensation on the reflector sur-
face, thus reducing effectiveness. A bulb must only be replaced by one of the
same type. The type i
s indicated on the bulb,
either on the glass part or on the base.
Xenon headlights
With this type of headlight, the user can re-
place the turn signal bulb. Replacement of
the dipped/main beam bulb must be done by
Technical Services, given that complex ele-
ments must be removed from the vehicle and
the automatic control system that incorpo-
rates it must be reset.
The Xenon bulbs discharge 2.5 times the
light flux and have an average lifespan of 5
times more than that of halogen bulbs, this
means that, except due to unusual circum-
stances, there is no need to change the bulbs
for the whole life of the vehicle. WARNING
● Tak e p
articular care when working on com-
ponents in the engine compartment if the en-
gine is warm, there is a risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● The high voltage element of gas discharge
bul
bs* (xenon light) must be handled correct-
ly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. CAUTION
● Remo v
e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights or parking lights be-
fore
you change a bulb. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u
sed bulbs in the proper manner. Note
● Dependin g on w
eather conditions (cold or
wet), the front lights, the fog lights, the tail
lights and the turn signals may be temporari-
ly misted. This has no influence on the useful
life of the lighting system. By switching on
the lights, the area through which the beam
of light is projected will quickly be demisted.
However, the edges may continue to be mis-
ted.
● Please check at regular intervals that all
lighting (es
pecially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
have the c
orrect new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead. The residue left by the fingerprints » 83
