Important safety notes
Xenon bulbs If your vehicle is equipped with xenon bulbs,
you can recognise this by the following: the
cone of light from the xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before startingt he engine. G
DANGER
Xenon bulbs carry ahigh 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
aqualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
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 setting checked regularly.
Other bulbs There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 122). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
If you require assistanc echangin gbulbs, con-
sult aqualified 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 servic elife of the bulbs. Always use alint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
aq ualified specialist workshop.

WARNING
The windscreen will not 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 ayear, ideally in spring

when the windscreen is dry, as this could
damage the wiper blades. Moreover ,dust
that has collected on the windscreen can
scratch the glass if wiping takes place when
the windscreen is dry.

the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
