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 compo-
nents. There is a risk of injury.
Allow these components to cool down before changing a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if:
Ryou touch it
Rit is hot
Ryou drop it
Ryou scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only fit spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit
and rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
Replace only the bulbs listed (
Ypage 70).
If you require assistance replacing bulbs,
consult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop.
The daytime driving lights and part of the
rear light clusters of your vehicle are equip-
ped with LED light bulbs. Do not replace these
bulbs yourself. Contact a qualified special-
ist workshop which has the necessary spe-
cialist knowledge and tools to carry out the
work required.
Headlamps and lamps are an important aspect
of vehicle safety. You must therefore make
sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
