that these function correctly at all times.
Have the headlamp settings checked regu-
larly. Only use the types of bulbs specified
here. If the new bulb still does not light up,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when fitting. G
Risk of injury
Bulbs and lamps can be very hot. You should
therefore allow them to cool down before you
change them. Otherwise, you could be burned
if you touch them.
Keep bulbs out of the reach of children. Oth-
erwise, they could damage them, for example,
and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you. Halogen bulbs are pressurised and could
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
G
Risk of injury
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con-
tacts on xenon bulbs. Therefore, never
remove the cover from xenon bulbs.
Do not change xenon bulbs yourself but have
them replaced at a qualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop. Overview: changing bulbs/bulb types
