fied specialist workshop and have the fuel
tank and fuel lines drained completely.
! Only refuel using unleaded premium
grade gasoline with at least 91 AKI/
95 RON.
! Only use the fuel recommended. Operat-
ing the vehicle with other fuels can lead to
engine failure.
! Do not use the following:
R E85 (gasoline with 85% ethanol)
R
E100 (100% ethanol)
R
M15 (gasoline with 15% methanol)
R M30 (gasoline with 30% methanol)
R M85 (gasoline with 85% methanol)
R M100 (100% methanol)
R Gasoline with metalliferous additives
R Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle. Do not use addi-
tives. Otherwise, engine damage may
occur. This does not include cleaning addi-
tives for the removal and prevention of res-
idue build-up. Gasoline may only be mixed
with cleaning additives recommended by
Mercedes-Benz; see "Additives". You can
obtain further information from any author-
ized Mercedes-Benz Center.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavaila-
ble and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions:
R
Only fill the fuel tank to half full with reg-
ular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
R
Do not drive at the maximum speed.
R Avoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for assis-
tance.

fied specialist workshop or visit

i E10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption.
Avoid driving at full throttle and sudden accel-
eration. Never refuel using fuel with a lower
AKI.

! Only refuel using super-grade unleaded
gasoline with at least 98 RON/88 MON
that conforms to European standard
EN 228 or an equivalent specification.
You could otherwise impair engine output
or damage the engine.
! Premium-grade unleaded gasoline with
an octane rating of 95 RON/85 MON may
be used as a temporary measure if the rec-
ommended fuel is not available. This may
reduce engine performance and increase
fuel consumption. Do not drive at full throt-
tle.
! Regular unleaded gasoline with an octane
rating of 91 RON/82.5 MON may also be
used as an emergency measure if the rec-
ommended 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 gasoline 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.
