Replacing bulbs
Important safety notes
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.
Have the headlamp setting checked regularly.
RAlways switch off the ignition before replacing bulbs in the lighting system. This will prevent
a short circuit.
RWear gloves and eye protection when chang-
ing a bulb.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube. The bulb
could may explode.
RA bulb could explode if:
-you touch it
-it is hot
-you drop it
-you scratch or score it
RMarks on the glass tube shorten the operating
life of a bulb. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit. Then rub
off the glass tube with a clean, lint-free cloth.
RMake sure that bulbs are protected from
moisture when operating and that they do not
come into contact with liquids. Make sure
that seals are seated correctly and replace
damaged seals.
RCheck the contacts for signs of corrosion and
clean these if required.
ROnly operate bulbs in closed lamps which
have been designed for this purpose.
ROnly use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
RIf the new bulb does not light up, consult a
qualified specialist workshop.
RHave lamps with LED bulbs repaired at a quali- fied specialist workshop only.
RHave the bulbs of the following lamps
replaced at a qualified specialist workshop
only:
-the additional brake lamps
-the license plate lighting
-Front fog lamps
-side marker lamp
