Notes on care
Regular and proper care maintains the value
of your vehicle.
i It is advisable to use Mercedes-Benz care
products.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop immediately, e.g. a
Mercedes-Benz Service Centre.
Repair damage caused by loose chippings
and remove the following substances imme-
diately, whilst avoiding rubbing too hard:
R Soak insect remains with insect remover
and rinse off afterwards .
R Soak bird droppings with water and rins e
off afterwards.
R Remove tree resin, oils, fuels and grease by
rubbing gently with a cloth soaked in clean-
ing or lighter fluid .
R Use silicone remover to remove wax.
R Use tar remover to remove tar stains. H
Environmental not
e
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally-responsible manner.
! Do not affix :
R stickers
R films
R magnetic plates or similar
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! Do not park the vehicle for a long perio d
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operatin g
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the very start,!
Do not use high pressure car wash sys-
tems. The strong water jet could damage
painted parts or attachments.
! Do not use a brush-free automatic car
wash that uses chemical agents to wash
the vehicle.
but preferably one without brushes.
If the vehicle is very dirty, prewash it befor e
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure the side windows are com-
pletely closed, the ventilation/heater
blower is fully turned off and the wind-
screen wiper switch is set to 0. The rai n
sensor may otherwise be activated, for
instance, leading to inadvertent wiper
sweeps being triggered. This could cause
damage to the vehicle.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen. Operation

hard objects, e.g. ice scrapers or rings. You
could otherwise cause damage to the win-
dows, rear window heating or aerial on the
rear window.
i Anti-glare film retrofitted to the insides of
the windows could interfere with radio or
mobile phone reception, especially if it is
conductive or metal-coated film. Informa -
