Leather upholstery* !
Cleaning
R Clean genuine leather covers using a
damp cloth, then wipe the covers down
afterwards using a dry cloth. When doing
this, make sure that the leather does not
become soaked. For leather care, you
should use leather care foam A 001 986
59 71 10. You can purchase this, for
example, at any Mercedes-Benz Service
Centre.
R Clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e. g. washing up liquid).
R Clean fabric covers with a microfibre
cloth moistened with a solution contain-
ing 1% detergent (e. g. washing up liquid).
When cleaning, take care not to rub too
vigorously and always wipe entire seat
sections to avoid leaving visible lines.
Leave the seat to dry afterwards. Clean- ing results depend on the type of dirt and
how long it has been there.
R Clean Alcantara covers with a damp
cloth. Make sure you wipe entire seat
sections to avoid leaving visible lines.
i Note that leather covers are subject to a
natural ageing process because they are a
natural product and may react in different
ways (e.g. increased formation of wrinkles)
to certain environmental influences (such
as high humidity, intense heat).
Note that regular care is essential to ensure
that the quality (both appearance and com-
fort) of the covers is retained over time.
Care of exhaust tail pipes (AMG vehi-
cles) Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface.
Regular care of the exhaust tail pipes will
ensure that their original shine is restored.
!
Do not clean exhaust tail pipes with alka-
line-based cleaning agents such as wheel
cleaner. Use the chrome cleaning agent recommen-
ded by Mercedes-Benz for cleaning. Infor-
mation about chrome cleaning agents can
be obtained from any Mercedes-Benz
Service Centre.
