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.
There are bulbs other than the xenon bulbs
that you cannot replace yourself. Replace
only the bulbs listed (Y page 118). Have the
bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.

Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers
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.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto- matic car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions, 120

inadvertently. This could damage the wind- screen wiper blades or scratch the wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. Combination switch

In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord- ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
screen wipers to wipe more frequently.
If the wiper blades are worn, the windscreen
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident. Replacing the wiper blades
Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen.
Hold the windscreen wiper arm firmly when you change the wiper blade. If you release
the windscreen wiper arm without a wiper
blade and it falls onto the windscreen, the
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you havethe wiper blades changed at a qualified
specialist workshop.
! Always position the windscreen wiper
arms vertically before folding them away
from the windscreen. By doing so, you will
avoid damage to the bonnet.
