system. Even small amounts of the wrong
fuel can result in damage to the fuel sys-
tem and the engine. Notify a qualified spe-
cialist workshop and have the fuel tank
and fuel lines drained completely.

The BRABUS engine is designed for
unleaded fuel with a minimum octane rat-
ing of 98 RON/88 MON. In countries where
unleaded fuel with a minimum octane rat-
ing of 98 RON is not available, you can use
unleaded fuel with an octane rating of
95 RON in emergencies. This may reduce
engine performance and increase fuel con-
sumption. When transporting a heavy
load, using fuel with 95 RON may result in
engine damage. smart recommends that
you always operate your vehicle (petrol
engine) with unleaded fuel which has a
minimum octane rating of 98 RON/88 MON.
! Only refuel using unleaded petrol with at
least 95 RON, which conforms to the Euro-
pean standard EN 228 or E DIN or an equiv-
alent specification.
Fuel of this specification may contain up to
10% ethanol. Your vehicle is suitable for
use with E10 fuel. You may refuel your
vehicle using E10 fuel.
Fuel that does not conform to EN 228 can
lead to increased wear as well as damage to
the fuel system, engine and exhaust sys-
tem.
! Only use the fuel recommended. Operat-
ing the vehicle with other fuels can lead to
damage to the fuel system, engine and
exhaust system.
!
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 infor-
mation on recommended additives enquire
at any smart centre.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the fuel injection
system could otherwise be blocked by par-
ticles from the fuel can.
!
Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.

The available fuel grade in some countries
may be inadequate. In this case, add the rec-
ommended additives. Observe the notes and
mixing ratios specified on the container.
BRABUS 80 kW: only refuel using unleaded
super grade petrol with an octane rating of at
least 98 RON/88 MON if you want maximum
performance from the engine. In emergencies
you can also use unleaded petrol with an
octane rating of at least 95 RON/85 MON.

WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk
of fire and explosion.
Always touch the vehicle body before
opening the fuel filler flap or touching the
fuel pump nozzle. This discharges any
electrostatic charge that may have built
up.
Do not get into the vehicle again during the
refuelling process. There is a risk of creating
an electrostatic charge.
