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,
the windscreen wipers may be activated
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. 1

Vehicles with a rain sensor: in theÄor
Å position, the appropriate wiping fre-
quency is automatically set according to the
intensity of the rain. In the Åposition, the
rain sensor is more sensitive than in the Ä
position, causing the windscreen 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. 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. Windscreen wipers

Z

Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! 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 have the wiper blades changed at a qualified
specialist workshop.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.

Care and treatment of matt paintwork !
Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork
shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matt finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs carried out
at a qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear matt finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
These notes also apply to light-alloy wheels
with a clear matt finish.
The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
Use only insect remover and car shampoo
from the range of approved Mercedes-Benz
care products. Cleaning vehicle parts
Cleaning the wheels G
WARNING
The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam- aged tyres or chassis components replaced
immediately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
Cleaning the windows G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury.
Always switch off the windscreen wipers and
the ignition before cleaning the windscreen orwiper blades.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol- vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring.
There is otherwise a risk of damaging the
windows. Care
399Maintenance and care Z

!
Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away. This
can lead to corrosion damage and damage to electronic components.
X Clean the inside and outside of the win-
dows with a damp cloth and a cleaning
agent that is recommended and approved
by Mercedes-Benz.
Cleaning the wiper blades G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury.
Always switch off the windscreen wipers and
the ignition before cleaning the windscreen or wiper blades.
! Do not pull on the wiper blade. Otherwise,
the wiper blade could be damaged.
! Do not clean wiper blades too often and
do not rub them too hard. Otherwise, the
graphite coating could be damaged. This
could cause wiper noise.
! Hold the wiper arm securely when folding
back. The windscreen could be damaged if
the wiper arm hits against it suddenly.
X Fold the wiper arms away from the wind-
screen.
X Clean the wiper blades carefully using a
damp cloth.
X Fold the windscreen wipers back again
before switching on the ignition.
Cleaning the exterior lighting !
Only use cleaning agents or cleaning
cloths that are suitable for plastic lenses.
Unsuitable cleaning agents or cleaning
cloths could scratch or damage the plastic lenses of the exterior lighting. X
Clean the plastic lenses of the exterior
lighting using a wet sponge and a mild
cleaning agent, e.g. Mercedes-Benz car
shampoo or cleaning cloths.
Cleaning the mirror turn signal !
Only use cleaning agents or cleaning
cloths that are suitable for plastic lenses.
Unsuitable cleaning agents or cleaning
cloths could scratch or damage the plastic lenses of the mirror turn signals.
X Clean the plastic lenses of the mirror turn
signals in the exterior mirror housing using
a wet sponge and mild cleaning agent, e.g.
Mercedes-Benz car shampoo or cleaning
cloths.
Cleaning AIRPANEL !
If you clean the sensors with a high-pres-
sure cleaner, make sure that you keep a
distance of at least 30 cm between the
vehicle and the high-pressure cleaner noz-
zle. Information about the correct distance is available from the equipment manufac-
turer.
Vehicles with AIRPANEL have shutters in the
radiator trim. If the vehicle is very dusty, the
adjustment range of the shutters may be
restricted. The actuation mechanics of the
radiator trim must then be cleaned with a
high-pressure cleaner. 400
