Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
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 lights can become very hot. For this
reason, allow them to cool down before
changing them. Otherwise, you could burn
yourself when 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, especially if
they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
G
Risk of injury
Xenon bulbs are under 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, do not
remove the cover on 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. Changing bulbs

Windscreen wiper blades
G
Risk of accident
The windscreen will no longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident. Replace
the wiper blades twice a year, ideally in spring
and autumn. G
Risk of accident
The wiper arms could start moving and cause
an injury if you leave the windscreen wipers
switched on. Remove the key from the ignition lock before
replacing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
To remove X
Remove the key from the ignition lock or
turn the key to position 0(KEYLESS GO).
X Fold the wiper arm away from the wind-
screen until it engages.
X Set the wiper blade at right angles to the
wiper arm. X
Remove the wiper blade from the retainer
on the wiper arm in the direction of the
arrow.
Fitting !
The two wiper blades are different
lengths. If you swap the wiper blades they
may scratch the windscreen. Make sure
that the longer wiper blade is fitted on the
driver's side.
X Compare the lengths of the two new wiper
blades.
X Slide the longer of the two new wiper
blades into the retainer on the wiper arm
on the driver's side in the opposite direc-
tion to the arrow.
X Repeat the same procedure on the front-
passenger's side with the shorter of the two
new wiper blades. 308
