Important safety notes
G
WARNING
Bulbs, lamps and connectors can get very
hot when operating. If you change a bulb,
you could burn yourself on these compo-
nents. 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.
Observe the following notes when changing a
bulb:
R Always switch off the ignition before replac-
ing bulbs in the lighting system. This will
prevent a short circuit.
R Wear gloves and eye protection when
changing a bulb.
R Do not use a bulb that has been dropped or
that has scratches on its glass tube. The
bulb could may explode.
R A bulb could explode if:
- you touch it
- it is hot
- you drop it
- you scratch or score it
R Marks on the glass tube shorten the operat-
ing 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.
R Make 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.
R Check the contacts for signs of corrosion
and clean these if required.
R Only operate bulbs in closed lamps which
have been designed for this purpose.
R Only use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
R If the new bulb does not light up, consult a
qualified specialist workshop. Replacing bulbs
