! Do not use diesel to refuel vehicles with a
petrol engine. Even a small 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.

E85 (petrol with 85% ethanol)
R
E100 (100% ethanol)

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.
Service products and capacities
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 a Mercedes-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 (
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.
If only regular unleaded petrol with an
octane rating of 91 RON/82.5 MON or
lower is available, you must have the vehi-
cle adapted to this fuel at a qualified spe-
cialist workshop.
i
E10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
