! Only use the fuel recommended. Oper-
ating the vehicle with other fuels can
lead to engine failure.
! Do not use the following:
E85 (petrol with 85% ethanol)

E100 (100% ethanol)
R
M15 (petrol with 15% methanol)
R
M30 (petrol with 30% methanol)

Do not mix such fuels with the fuel rec-
ommended for your vehicle. Do not use
additives. Engine failure may otherwise
occur. This does not include cleaning
additives for the removal and prevention
of residue build-up. Petrol must only be
mixed with cleaning additives recom-
mended by smart, see "Additives". For
further information enquire at any smart
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
station staff.

E10 fuel contains up to 10% bioethanol.
Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using
E10 fuel.
As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol with an octane rating of
91 RON/82 MON. This may reduce engine
performance and increase fuel consump-
tion. Avoid driving at full throttle and
sudden acceleration. Never refuel using
fuel with a lower RON/MON.
i
In some countries, the available petrol
may not be sufficiently low in sulphur.
This fuel can temporarily produce
unpleasant odours, especially on short
journeys. As soon as sulphur-free fuel
(sulphur content < 10 ppm) is used for
refuelling, the odours are reduced.

Additives

! Operation of the engine with fuel addi-
tives added later can cause engine dam-
age. Therefore, do not mix any fuel addi-
tives with the fuel. This does not include
additives for the removal and prevention
of residue build-up. Petrol must only be
mixed with additives recommended by
smart. Observe the instructions for use
in the product description. For further
information on recommended additives
enquire at any smart centre.
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 centre, the petrol may be mixed with
the cleaning additive recommended by
smart. You must observe the notes and mix-
ing ratios specified on the container.
