!
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.
Cleaning the seat covers !
Do not use microfiber cloths to clean
genuine leather, artificial leather or
Alcantara®
covers. If used often, these can
damage the cover.
! Observe the following when cleaning:
R clean genuine leather covers carefully
with a damp cloth and then wipe the
covers down with a dry cloth. Make sure
that the leather does not become
soaked. It may otherwise become rough
and cracked. Only use leather care
agents that have been tested and
approved by Mercedes-Benz. You can
obtain these from a qualified specialist
workshop, e.g. a Mercedes-Benz Service
center.
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
sections 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 Alcantara® covers with a damp
cloth. Make sure you wipe entire seat
sections to avoid leaving visible lines. i
Note that regular care is essential to
ensure
that the appearance and comfort of
the covers is retained over time.
Cleaning the seat belts X
Use clean, lukewarm water and soap
solution.
! Do
not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by warming them above 176 ‡ (80 †) or
placing them in direct sunlight. G
WARNING
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Cleaning the headliner and carpets X
Roof lining: use soft brushes or dry
shampoo if it is particularly dirty.
X Carpets: use carpet and textile cleaners
that have been approved and
recommended by Mercedes-Benz. Care
