Damaged seals or electrical components
can lead to leaks or failures.
Cleaning the wheels !
Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosio nofthe brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Cleaning 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.
! Do not affix:
R stickers
R films
R magnetic plates or similar items to painted surfaces. You could otherwise
damage the paintwork.
If water no longer forms "beads" on the paint
surface, use the paint care products
recommended and approved by Mercedes-
Benz.T his is the case approximately every
three to five months, depending on the
climate conditions and the care product used.
If the dirt has penetrated the paint surface or
if the paintwork has become dull, then the
paintwork should be cleaned. Use the
cleaning product Paint Cleaner, which has
been approved by Mercedes-Benz.
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 paintwork quickly and provisionally.
Matte finish care If your vehicle has a clear matte finish,
observe the following instructions in order to
avoid damage to the paintwork due to
incorrect care.
These notes also apply to light alloy wheels
with a clear matte finish.
!
Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to
shine.
! The following may cause the paint to
become shiny and thus reduce the matte
effect:
R Vigorous rubbing with unsuitable
materials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or
polishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (shiny, spotted areas). Care
279Maintenance and care Z
X
Before cleaning the display, make sure that
it is switched off and ha scooled down.
X Clean the display surface using a
commercially available microfiber cloth
and TFT/LCD display cleaner.
X Dry the display surface using a dry
microfiber cloth.
Cleaning the plastic trim G
WARNING
Care products and cleaning agents containing
solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts may
come loose in the event of air bag
deployment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
! 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 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 genuine wood and trim
elements !
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 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 microfiber cloths to clean
genuine leather, artificial leather or
Alcantara® covers. If used often, these can
damage the cover.
i Note that regular care is essential to
ensure that the appearance and comfor tof
the covers is retained ove rtime.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R Differences in the texture
R Signs of stretching and marking
R Sligh tnuances of color
These are characteristics of leather and not
material defects. 282
CareMaintenance and care
Gasoline
Fuel grade
!
Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the
ignition if you accidentally refuel with the
wrong fuel.O therwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could resul tindamage to the
fuel system and the engine. The repair
costs are high .Notify aqualified specialist
workshop and have the fuel tan kand fuel
lines drained completely.
! You should only refuel with unleaded
premium-grade gasoline as thi savoids
damaging the catalytic converter.
If engine running problems are apparent,
have the cause checked immediately and
repaired .Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.
! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline may be used.
If there is no premium-grade unleaded
gasoline available and regular unleaded
gasoline must be used, please observe the
following precautions:
R only fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soo nas possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R if the vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above 3000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than 0001of the pedal travel.
Only refuel using premium-grade unleaded
gasoline with a minimum octane rating of 91. Reformulated Gasoline (RFG) and/or
unleaded gasoline with additives can be used.
The concentration of additives in the fuel,
however, must not exceed 10%, e.g.:
R
Ethanol
R TAME
R ETBE
R IPA
R TBA
For MTBE, the concentration should not
exceed 15%.
The concentration of methanol in gasoline,
including other additives, must not exceed
3%.
Using mixtures of methanol and ethanol is not
permitted. Gasohol, a mixture of 10% ethanol
and 90% unleaded gasoline may be used.
All of these blends must fulfill the fuel
requirements, e.g.:
R knock resistance
R boiling point
R vapor pressure
You will usually find information aboutt he fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for
assistance.
i For more information, contact a qualified
specialist workshop.

Do not use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside
temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as a result
of aging, soot and fuel deposits. It is therefore
strongly recommended that you carry out
regular oil changes using an approved engine
oil with the appropriate SAE classification. Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapo rpockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the
important safety notes on service products
(Y page 337).
The brake fluid change intervals can be found
in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist
workshop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled next to the filler neck.T horoughly
clean the antifreeze from components before
starting the engine.
! Only add coolant that has been premixed
with the desired antifreezep rotection. You
could otherwise damage the engine. Service products and filling capacities
