Gasoline
Fuel grade
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could result in damage to the
fuel system and the engine. Notify a quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Only refuel using premium-grade unlea-
ded gasoline with at least 91 AKI/95 RON
(91 octane).
!Only use the fuel recommended. Operating
the vehicle with other fuels can lead to
engine failure.
!Do not use the following:
RE85 (gasoline with 85% ethanol)
RE100 (100% ethanol)
RM15 (gasoline with 15% methanol)
RM30 (gasoline with 30% methanol)
RM85 (gasoline with 85% methanol)
RM100 (100% methanol)
RGasoline with metalliferous additives
RDiesel
Do not mix such fuels with the fuel recom-
mended for your vehicle. Do not use addi-
tives. Engine failure may otherwise occur.
This does not include cleaning additives
for the removal and prevention of residue
build-up. Gasoline must only be mixed with
cleaning additives recommended by smart
(see "Additives"). For further information
inquire at any smart 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 unavail-
able 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
regular unleaded gasoline and fill the
rest with premium-grade unleaded gas-
oline 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 on the Internet
at http://www.smartusa.com (USA only).
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
acceleration. Never refuel using fuel with a
lower octane rating.
Information on refueling (
Ypage 97).
Additives
!Operating the engine with subsequently
added fuel additives can lead to engine
damage. Do not mix any fuel additives with the fuel. This does not include additives
for the removal and prevention of residue
buildup. Gasoline must only be mixed with
additives recommended by smart. Comply
with the instructions for use on the product
label. For further information on recom-
mended additives, inquire at any smart
center.
smart recommends that you use fuel brands
that have additives.
The quality of the fuel available in some
countries may not be sufficient. Residue
could build up in the injection system as a
result. In this case, in consultation with a
smart center, the gasoline may be mixed with
the cleaning additive recommended by smart.

Fuel consumption information
HEnvironmental note
CO
2(carbon dioxide) is the gas which sci-
entists believe to be principally respon-
sible for global warming (the greenhouse
effect). Your vehicle's CO
2emissions are
directly related to fuel consumption and
therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as
environmental influences, road condi-
tions or traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it
serviced regularly.
The vehicle will use more fuel than usual in
the following situations:
Rat very low outside temperatures
Rin city traffic
Ron short journeys
Rin mountainous terrain
Engine oil
General notes
!Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals.
Do not change the engine oil or oil filter in order to achieve longer replacement inter-
vals than those prescribed. You could oth-
erwise cause engine damage or damage to
the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
(
Ypage 207).
The engine oils are matched to the perform-
ance of smart engines and service intervals.
You should therefore only use engine oils and
oil filters that are approved for vehicles
with maintenance systems.
Consult a smart center to view a list of
approved engine oils and filters. Or visit the
website http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.
