If standard unleaded gasoline is unavaila-
ble and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions:
ROnly 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.
RDo not drive at the maximum speed.
RAvoid 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.
iFor further information, consult a quali-
fied specialist workshop or visit

iE10 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.
Information on refueling (
Ypage 146).
Additives
!Operating the engine with fuel additives
added later can lead to engine failure. Do
not mix fuel additives with fuel. This does
not include additives for the removal and
prevention of residue buildup. gasoline
must only be mixed with additives recom-
mended by Mercedes-Benz. Comply with
the instructions for use on the product
label. More information about recommen-
ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels that have additives. The quality of the fuel available in some coun-
tries may not be sufficient. Residue could
build up in the injection system as a result. In
such cases, and in consultation with an
authorized Mercedes-Benz Center, the gaso-
line may be mixed with the cleaning additive
recommended by Mercedes-Benz.
You mu
st
observe the notes and mixing ratios specified
on the container.
Diesel
Fuel grade
GWARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
!Only use commercially available vehicular
ULTRA-LOW SULFUR DIESEL FUEL (ULSD,
15 ppm maximum sulfur content) that
meets the ASTM D975 standard. If you do
not refuel with ULSD, you may damage the
BlueTEC exhaust gas aftertreatment sys-
tem of the vehicle.
!Do not use gasoline to refuel vehicles with
a diesel engine. Do not mix diesel fuel with
gasoline, kerosene or paraffin. This may
otherwise result in damage to the fuel sys- tem and engine.
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.
