It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
WARNING
Do not use petrol to refuel adiesel tank.N ever
mix diesel with petrol. Doin gsocould damage
the fuel system and the engine. The vehicle
could also catc hfire.
! 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 wrong fuel 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 workshop and have
the fuel tank and fuel lines drained com-
pletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use afilter when adding fuel from afuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.

! Only refue lusing unleaded petrol with at
least 95 RON/85 MON that conforms to
European standard EN 228 or EDIN
51626-1 or an equivalent specification.
Fuel with this specification may contain up
to 10 %ethanol.

R Petrol with metallic additives

Do not mix these fuels with petrol, and do
not use any additives. This can otherwise
lead to engine damage. This does not
include cleaning additives for the removal
and prevention of residue build-up. Only
cleaning additives recommended by
Mercedes-Ben zshould be added to petrol,
see "Additives". You can obtain further
information from any Mercedes-Benz
Service Centre.
Usuallyy ou will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.
i E10 fuel contains up to 10 %bioethanol.
Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.
i If the recommended fuel is not available,
but only as atemporary measure, you may
also use unleaded petrol with an octane
rating of 91 RON/82.5 MON. This may
reduce engine performance and increase
fuel consumption .Avoid driving at full
throttle.
Information on refuelling (Y page157).
AMG vehicles
! Only refue lusing super unleadedp etrol
with at least 98 RON/88 MON that con-
forms to European standard EN 228 or an
equivalent specification.
You can otherwise impair engine outpu tor
damage the engine.
! Premium-grade unleaded petro lwith an
octane ratin gof95RON/85 MON may be
used as atemporary measure if the recom-
mended fuel is not available. This may
reduce engin eperformanc eand increase
fuel consumption .Asmuch as possible,
avoid driving at full throttle. !
Regular unleadedp etrol with an octane
rating of 91 RON/82.5 MON may also be
used as atemporary measure if the recom-
mended fuel is not available.
Doing so results in noticeably higher fuel
consumption, and the engine power output
is noticeably reduced. Avoid driving at full
throttle.
If only regularu nleaded petrol with an
octane rating of 91 RON/82.5 MON or
lowe risa vailable, you must have the vehi-
cle adapted to this fuel at aqualified spe-
cialist workshop.
i E10 fuel contains up to 10 %bioethanol.
Your vehicle is suitablef or use with E10
fuel. You can refuel your vehicle using E10
fuel.
CLS 350 BlueEFFICIENCY
! Only refuel using premium-grade sulphur-
free unleadedp etrol with at least 95 RON/
85 MON that conformstoE uropean stand-
ard EN 228 or an equivalent specification.
You could otherwise impair engine output
or damage the emission control system.
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
soon as sulphur-free fuel (sulphur content
<10p pm) is used for refuelling, the odours
are reduced.
Additives
! Do not refuel with low grade fuel and do
not use fuel additives that have not been
tested and approved for Mercedes-Benz
vehicles. Otherwise the fuel system could
malfunction or be damaged.
One of the major problems with low-grade
fuel is the creation of carbon deposits during
the proces sofburningfuel. Mercedes-Benz
recommends that you use fuel brands that
have additives.
If you use fuels without these additives for a
longer period of time, ther emay be abuild-up Service product
