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.
XWipe the wooden trim and trim pieces with a
damp, lint-free cloth, e.g. a microfiber cloth.
XHeavy soiling: use car care and cleaning
products 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.
iNote that regular care is essential to ensure
that the appearance and comfort of the cov-
ers is retained over time.
Genuine leather seat covers
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully with a damp cloth and then wipe the covers
down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
ROnly 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:
Rdifferences in the texture
Rmarks caused by growth and injury
Rslight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
Rclean cloth covers with a microfiber cloth
moistened with a solution contain ing 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.
Rclean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡(80 †)
or in direct sunlight.
XUse clean, lukewarm water and soap solution.
Cleaning the headliner and carpets
XHeadliner: if it is very dirty, use a soft brush or
dry shampoo.
XCarpets: use the carpet and textile cleaning
agents recommended and approved by
Mercedes-Benz.
330Care
Maintenance and care
Comply with the important safety notes for ser-
vice products when handlin g coolant
(
Ypage 378).
The coolant isa mixture of water and ant i-
freeze/corrosion inh ibitor. It is responsible for
the foll owing:
RAnti-corrosion protection
RAntifreeze protection
RRaisin g the boiling point
If the coolant has antifreeze protection downto
-35 ‡ (-37 †), the boilingpoin t of the coolant
during operation is approximately 266 ‡
(130 †).
The antifreeze concentrate /corrosion inh ibitor
concentration inthe engine co oling system
should:
Rbe at least 50 %.This willprotect the engine
co olin g system against freezing downto
approximate ly-35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat willnotbe
dissipat ed as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inh ibitor concentrate inaccordance
wit h MB Specifications for Service Products
310.1.
iWhen the veh icle isfirstdeliv ered, it is fille d
wit h a coolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant ischecked with every mainte-
nance interval at a qualified specialist work-
shop.

Windshield washer system
Important safety notes
GWARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There isa risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
!Only MB SummerFit and MB WinterF it
washer fluid should bemixed together. The
spray nozzles may otherwise become
blocked.
Do not use distilled or de-ionized water. Other-
wise, the level sensor may givea false reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypage 378).
At temperatures above freezing:
XFill the washer fluid reservoir with a mixture of
water and windshield washer fluid, e.g. MB
SummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to the infor-
mation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
