Important safety notes
G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking are therefor eprohibite dwhen
handling fuels.
Switch off the engin eand the auxili aryh eating
befor erefuelling. G
WARNING
Do not com einto contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breath einfuel vapours. G
WARNING
Do not use petrol to refuel vehicles with adie-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which could lead to avehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel vehicles with
apetrol engine. Even small
amounts of the wron gfuel result in damage
to the fuel system and the engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
aq ualified specialist worksho pand have
the fuel tank and fuel lines drained com-
pletely. Petro
l(EN 228, DIN 51626)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/8 5MON, whic hconform stoEuro-
pean standard EN 228 or an equivalent
specification.
! Do not use the following:
R E85 (petrol with 85% ethanol)
R E10 0(100% ethanol)
R M15 (petro lwith 15% methanol) 152

R M10 0(100% methanol)
R Petrol wit hmetallic additives
R Diesel
Do not mix fuel ssuch as this with petrol
and do not use any additives. Doing so may
cause engine damage. This does not
include additives for the removal and pre-
vention of residue build-up. Petrol must
only be mixed with additives recommended
by Mercedes-Benz. More information about
recommended additives can be obtained
from any Mercedes-Ben zService Centre.
! Use afilter when adding fuel from afuel
can. The fuel lines and/or the diesel injec-
tion system could otherwis ebeblocked by
particles from the fuel can.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is E10 compatible. You can
refuel your vehicle using E10 premium-
grade petrol.
i If the recommended fuel is not available,
but only as atemporary measure, you may
also use regula runleaded petrol,
91 RON/82.5 MON. Thi smay reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause
deposits to build up. In consultation with a
Mercedes-Ben zService Cent re,this petrol
ma ybem ixed with the additive recommen-
ded by Mercedes-Ben z(part no.
A0009 89254510). Yo umust observe the
notes and mixin gratios specified on the
container.
For further information on "Fuel", see
(Y page 374). !
Only refuel using unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conform stoEuro- pean standar
dEN2 28or an equivalent
specifi cation.
You can otherwise impair engine output or
damage the emission contro lsystem.
i In some countries, the available petrol
may not be sufficiently low in sulphur. This
fuel can temporarily produce unpleasant
odours, especially on short journeys. As
soo nassulphur-free fuel (sulphur content
<10p pm) is used for refuelling, the odours
are reduced. Diesel (EN 590)
Fuel grade !
When refuelling, only use diesel fuel that
confor ms to th eEuropean standard EN 590
or is of equivalent quality. You can other-
wise impair engine output or damage the
engine.
! Vehicles with diesel particle filters: in
countries outsid ethe EU ,only use low sul-
phu rEuro diesel with asulphu rcontent of
under 50 ppm. Otherwise, the emission
con trol system coul dbedamaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuels
with ahigher sulphur conten tare avail able,
the vehicle's oil change intervals are
shorter. More information about intervals
for changing the oil can be obtained from
any Mercedes-Benz Service Centre.
! Only use fuel that complies with the EN
590 European standard. Fuel that does not
compl ywithEN5 90can lea dtoincreased
wear, engin edamag eand damage to the
exhaust system.
Do not use the following:
R marine diesel

Cleaning the plastic trim G
WARNING
When cleanin gthe steering wheel boss and
dashboard, do not use cockpit sprays or
cleanin gagents containing solvents. Cleaning
agent scontaining solvents cause the surface
to becom eporous, and as aresult plastic

R scented oil bottles or similar items
You could otherwise damage the plastic.
! Do not allow cosmetics, insect repellent
or sunscreen to come in contact with the
plastic trim .This maintain sthe high-quality
look of the surfaces.
X Wipe the plastic trim with adamp, lint-free

engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Benz recommends that you have the oil

Engine oil viscosity Viscosit
ydescribes the flow characteristi cs
of afluid. If an engin eoil has ahigh viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SA Eclassification (viscosity). The table
below shows you which SA Eclassifications are to be used. The low-temperature proper-
ties of engin eoils can be significantly
impaired durin goperation due to, for exam-
ple, ageing or soot and fuel accretion. It is
therefore strongly recommende dtoobserve
