The ASSYST service interval display informs
you of the next service due date.
If
a service due date has been exceeded, you
also hear a warning tone.
The multifunction display shows a service

parts may break away and be thrown around
the
interior when an air bag is deployed, which
may result in severe injuries.
! Do not affix the following to plastic
surfaces:
R stickers
R films
R scented oil bottles or similar items
You can otherwise damage the plastic.
! Do not allow cosmetics, insect repellent
or sunscreen to come into contact with the
plastic trim. This maintains the high-quality
look of the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfiber cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
The
surface may change color temporarily.
Wait until the surface is dry again.
Cleaning the steering wheel and gear or
selector lever X
Thoroughly wipe with a damp cloth or use
leather care agents that have been
recommended
and approved by Mercedes-
Benz.
Cleaning wooden trim and trim strips !
Do
not use solvent-based cleaning agents
such as tar remover, wheel cleaners,
polishes or waxes. There is otherwise a risk
of damaging the surface.
! Do not use chrome polish for trim strips.
The trim strips 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 strips.
If the chrome-plated trim strips are very
dirty, you can use a chrome polish. If you
are unsure as to whether the trim strips are chrome-plated or not, consult an
authorized Mercedes-Benz Center.
X Wipe the wooden trim and trim strips with
a damp, lint-free cloth, e.g. a microfiber
cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the seat covers !
Do not use microfiber cloths to clean
genuine leather or artificial leather covers,
as these are too aggressive and, if used
often, may 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.
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dishwashing liquid).
R clean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dishwashing 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.
i Note that regular care is essential to
ensure that the appearance and comfort of
the covers is retained over time. Care

! Always use a suitable coolant mixture,
even
in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R corrosion protection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant in the pressure system is
approximately 266 ‡ (130 †).
The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor. Mercedes-Benz recommends an
antifreeze/corrosion inhibitor in accordance
with MB Specifications for Service Products
310.1.
The coolant is checked with every
maintenance interval at a qualified specialist
workshop.
i When the vehicle is first delivered, it is
filled with a coolant mixture that ensures
adequate antifreeze and corrosion
protection.
The engine cooling system is filled with
coolant at the factory; this coolant contains
antifreeze/corrosion inhibitor that ensures protection down to approximately -35 ‡
(-37 †).
Your vehicle has a range of aluminum
components. Aluminum components in the
engine make it necessary to use antifreeze/
corrosion inhibitor that has been specifically
formulated to protect the aluminum parts.
Using other antifreeze/corrosion inhibitors
without these characteristics affects the
service life.
The
coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and to provide protection from
overheating. In the Maintenance Booklet, you
can find information on the intervals for
renewal.
The renewal interval is determined by the
coolant type and the engine cooling system
design. The renewal interval in the
Maintenance Booklet is only valid if the
coolant is renewed or added to with
Mercedes-Benz approved products.
Therefore, only use MB 326.0 antifreeze/
corrosion inhibitor or another Mercedes-Benz
approved product of the same specification.
Information on other products with the same
specifications that are approved by
Mercedes-Benz can be obtained at an
authorized Mercedes-Benz Center or on the
Internet at
http://bevo.mercedes-benz.com.
If the coolant level is too low, MB 325.0
antifreeze/corrosion inhibitor should be
added. Have the engine cooling system
checked for possible leaks. Service products and filling capacities
