Fuel grade
!
Do not use diesel to refuel vehicles with a
petrol engine. Even asmall quantity of die-
sel will damage the fuel injection system.
! Only refuel using unleaded, premium-
grade petrol with at least 95 RON/
85 MON that conforms to European stand-
ard EN 228 or E DIN 51626-1 or an equiv-
alent specification.
! Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R Petrol with metallic additives
R Diesel
Do not mix fuels such 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-Benz Service Centre.
Usually you 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 a temporary 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.
The quality of the fuel available in some
countries may not be sufficient .Residue
could build up as a result. In such cases,
and in consultation with aMercedes-Benz
Service Centre, the petrol may be mixed
with the additive recommended by
Mercedes-Benz( part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
Information on refuelling (Y page 142).
AMG vehicles
! Only refuel using super unleaded petrol
with at least 98 RON/88 MON that con-
forms to European standard EN 228 or an
equivalent specification.
You can otherwise impair engine output or
damage the engine.
! Premium-grade unleaded petrol with an
octane rating of 95 RON/85 MON may be
used as a temporary measure if the recom-
mended fuel is not available. This may
reduce engine performance and increase
fuel consumption .As much as possible,
avoid driving at full throttle.
! Regular unleaded petrol with an octane
rating of 91 RON/82.5 MON may also be
used as a temporary 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. 304

Vehicles with adiesel particle filter: in
countries outside the EU, only refuel with
low-sulphur Euro diesel with a sulphur con-
ten tunde r50p pm; otherwise the emission
control system could be damaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuel with
a high sulphur conten tis available, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
aboutt he interval for oil change can be
obtained from any qualified specialist
workshop.
Usually you 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.

Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be
insufficient .Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climati cconditions.
i Further information on country-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.
Flow improver
To improve the low-temperature resistance of
diesel fuel, a flow improver can be attached.
The effectiveness of a flow improver is not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz. During use, please
observe the information on operation.
Correct dosage and sufficient mixing are deci-
sive in improving low-temperature resistance with the flow improver. Overdosage can
potentially even decrease low-temperature
resistance and must therefore be avoided.
Follow the manufacturer's guidelines on dos-
age.
Mix the additive into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can arise through heating the fuel system,
e.g. through parking in a heated garage.
More information about recommended flow
improvers can be obtained from any qualified
specialist workshop.
Notes on fuel consumption
H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related to
fuel consumption and therefore depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences or road conditions
You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly.
The vehicle will use more fuel than usual in
the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
i Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These
documents are delivered with your vehicle.
The consumption figures were in each case
based on the currently applicable version: 306
