Care
400
! 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.
Clean the inside and outside of the win-
X
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.
Fold the wiper arms away from the wind-

Cleaning the exterior lighting

lenses of the exterior lighting.
Clean the plastic lenses of the exterior
X
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.
Clean the plastic lenses of the mirror turn
X
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.
