Emergencies
Full-LED headlight system*
F u
l
l-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced.
Double headlight bulb change
Changing bulbs requires a certain degree of
practical skill. If in doubt, we recommend you
have defective bulbs changed by a special-
ised service or, in case of an emergency,
seek professional assistance.
● Switch off the ignition and all of the lights
before c
hanging a bulb.
● Do not touch the glass part of the bulb with
your bar
e 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.
● There is a storage area for the bulb box in
the spar
e wheel well or below the carpet in
the luggage compartment. WARNING
● Tak e p
articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● 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 and the parking light
before c
hanging 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 rear
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. ●
Ple a
se check at regular intervals that all
lighting (especially 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. Otherwise, the fingerprints left on
the glass will vaporise as a result of the heat
generated by the bulb, they will be deposited
on the reflector and damage its surface. Double headlight bulbs
