Cleaning the steering wheel and gear or
selector lever X
Thoroughly wipe with a damp cloth or use
leather care agents that have been recom-
mended and approved by Mercedes-Benz.
Cleaning genuine wood and trim ele-
ments !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, polishes or waxes. There is otherwise a risk of damag-
ing the surface.
! Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and can
lose their shine if chrome polish is used. Use
a damp, lint-free cloth instead when cleaning the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you are
unsure as to whether the trim pieces are
chrome-plated or not, consult an authorized
Mercedes-Benz Center.
X Wipe the wooden trim and trim pieces with a
damp, lint-free cloth, e.g. a microfiber cloth.
X Heavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers General notes
! Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
Note that regular care is essential to ensure that the appearance and comfort of the covers is
retained over time. Genuine leather seat covers
! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully with
a damp cloth and then wipe the covers
down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R differences in the texture
R marks caused by growth and injury
R slight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
! Observe the following when cleaning:
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
R clean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there.
R clean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
