Important safety notes
G
WARNING
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. !
Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore
make sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
Observe the following notes when changing a
bulb:
R Always switch off the ignition before replac-
ing bulbs in the lighting system. This will
prevent a short circuit.
R Wear gloves and eye protection when
changing a bulb.
R Do not use a bulb that has been dropped or
that has scratches on its glass tube. The
bulb could may explode.
R A bulb could explode if:
- you touch it
- it is hot
- you drop it
- you scratch or score it
R Marks on the glass tube shorten the operat-
ing life of a bulb. Do not touch the glass
tube with your bare hands. If necessary,
clean the glass tube when cold with alcohol
or spirit. Then rub off the glass tube with a
clean, lint-free cloth.
R Make sure that bulbs are protected from
moisture when operating and that they do
not come into contact with liquids. Make
sure that seals are seated correctly and
replace damaged seals.
R Check the contacts for signs of corrosion
and clean these if required.
R Only operate bulbs in closed lamps which
have been designed for this purpose.
R Only use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
R If the new bulb does not light up, consult a
qualified specialist workshop. Replacing bulbs

Switching the windshield wiper
on/off
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the wind-
shield.
For this reason, you should always switch
off the windshield wipers in dry weather. 1

X Turn the key to position 1 or 2 in the igni-

X Turn the í wiper switch to the corre-
sponding position.
In the Ä or Å
positions, 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 to
precipitation than in the Ä position, caus-
ing the windshield wipers to wipe more fre-
quently.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blades can
be found under "Replacing wiper blades"

When you release the è switch, the rear
window wiper continues to wipe for about
another five seconds. The rear window
wiper then wipes according to the original
position 2 or 3.
The rear window wiper switches on automati-
cally if you engage reverse gear and the wind-
shield wipers are on.
If the vehicle is stationary and you open the
tailgate or rear-end door, the rear window
wiper will stop automatically. The rear window
wiper will only resume wiping again when the
tailgate and rear-end door are closed and you
pull away again.
The rear window will no longer be wiped prop-
erly if the wiper blade is worn. This may pre-
vent you from observing the traffic conditions.

Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you
could be trapped by the wiper arm. There is
a risk of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood/tailgate or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield/rear
window, the windshield/rear window may
be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the wiper
rubber.
Wiper blades are wear parts. The windshield
will no longer be wiped properly if the wiper
blades are worn. This may prevent you from
observing the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yel-
low.110
