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 a year, ideally in spring
and autumn.
! 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 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. Windscreen wipers

Brake ,the HOLD func-
tion, hill start assist, the adaptive brake lights and ESP ®

stabilisation are also deactivated, for example.
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.

X
Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighte rfluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Care and treatment of matt paintwork If your vehicle has a clear mat
tfinish, observe
the following instructions in order to avoid
damage to the paintwork due to incorrect
care.
These notes also apply to light alloy wheels
with a clear mat tfinish.
! Neve rpolish 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 performed
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
! Do not use wash programs with a hot wax
treatment under any circumstances. i
The vehicle should preferably be washed
by hand using a soft sponge, car shampoo
and plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.
Cleaning the windows G
WARNING
Switch off the windscreen wipers and remove
the key from the ignition lock before cleaning
the windscreen or the wiper blades. On vehi-
cles with KEYLESS-GO, press the Start/Stop
button repeatedly until all indicator lamps in
the instrument cluster have gone off. The
windscreen wipers could otherwise move and
injure you.
! Only fold the windscreen wipers away
from the windscreen when vertical. Other-
wise, you will damage the bonnet.
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.
! 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.
! 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.T his
can lead to corrosion damage and damage
to electronic components.
