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
M85 (petrol with 85 %methanol)
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
R heating oil
R bio-diesel
R vegetable oil
R petrol Refuelling

R kerosene
Do not mix these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver ;see "Low out-
side temperatures".
! Use afilter when adding fuel from afuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can.
For further information on "Fuel", see
(Y page 374).
Low outsid etemperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
peratur eclasses are defined in EN 590 .Refu-
elling with diesel fuel which complies with the
climatic specification sofstandard EN 590
can hel ptoprevent operatin gproblems. At
exceptionall ylow tempera tures, it is possible
that the flow properties of the fuel ma ybe
inadequate. This also applies to fuel that has
not been adapted to suit the climatic condi-
tions, e.g. diesel fuel from warmer regions.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improv
ethe
cold resistan ceof diesel fuel. The effective-
ness of aflow improver is not guaranteed with
every diesel fuel.
Correc tdosage and thorough mixing ar edeci-
sive factor sinensuring improvement in low-

fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using aflow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
