! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following: R
tires R
door gaps, roof gaps, joints, etc. R
electrical components R
battery R
plug-type couplings R
lights R
seals R
trim R
ventilation slots
Damaged seals or electrical components can
lead to leaks or failures.
! Vehicles with decorative foil: parts of your
vehicle are covered with decorative foil. Main-
tain a distance of at least 27.5 in (70 cm)
between the foil-wrapped parts of the vehicle
and the nozzle of the high pressure cleaner.
Information about the correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
The water temperature of the high-pressure
cleaner must not exceed 140 °F (60 °C).
Cleaning the paintwork
! Do not affix: R
stickers R
films R
magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop. X
Remove dirt immediately, where possible,
while avoiding rubbing too hard. X
Soak insect remains with insect remover and
rinse off the treated areas afterwards. X
Soak bird droppings with water and rinse off
the treated areas afterwards. X
Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid. X
Use tar remover to remove tar stains. X
Use silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz. This is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
If dirt has penetrated the paint surface or if the
paint has become dull, the paint cleaner recom-
mended and approved by Mercedes-Benz
should be used.
Do not use these care products in the sun or on
the hood while the hood is hot. X
Use a suitable touch-up stick, e.g. MB Touch-
Up Stick, to repair slight damage to the paint-
work quickly and provisionally.
Matte finish care
! Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following can give the paint a glossy
appearance and thus reduce the matt effect: R
Rubbing hard with unsuitable agents R
Washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the
purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Only use automatic car washes which cor-
respond to the latest technological stand-
ards. Never use wash programs which finish
by treating the vehicle with hot wax.
Observe these notes if your vehicle has a clear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
a clear matt finish.332
Care
Maintenance and care

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 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.
i Note 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: 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.
Cleaning the seat belts
G WARNING
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.336
Care
Maintenance and care

The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following: R
anti-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
during operation is approximately 266 ‡
(130 †).
The antifreeze concentrate/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 , hea t will no t be
dissipated as effectively.
Mercedes-Ben z recommends an antifreeze/
corrosion inhibitor concentrat e in accordance
wit h MB Specification s fo r Servic e Products
310.1.
i Whe n th e vehicle is first delivered, it is filled
wit h a coolan t mixture that ensures adequat e
antifreez e an d anti-corrosio n protection .
i The coolan t is checke d at specifie d intervals
at a qualifie d specialis t workshop .
