If the available fuel is not sufficiently low in sul-
phur, it may produce unpleasant odours.
Refuel only using unleaded, sulphur-free spark-
ignition engine fuel that conforms to European
EN 228, or an equivalent specification.
This fuel may contain up to 10% ethanol by vol-
ume. Your vehicle is suitable for use with E10 fuel.
The following compatibility indications for fuel
apply to your vehicle:
1
For petrol with maximum 5% ethanol by vol-
ume
2
For petrol with maximum 10% ethanol by vol-
ume
The compatibility indications for fuel on the vehi-
cle according to the European standard EN 16942
can be found on the information label in the fuel
filler flap or on the fuel dispenser or pump nozzle
suitable for your vehicle throughout Europe.
The recommended octane number for your vehi-
cle can be found on the information label on the
fuel filler flap.
Refuel only using premium-grade unleaded petrol
with an octane number of at least 98 RON if you
F232 0017 02
wish to achieve maximum engine output. Alterna-
tively, you can also refuel using premium-grade
unleaded petrol with an octane number of at least
95 RON.
In exceptional cases, if the recommended fuel is
not available, you may also use regular unleaded
petrol with an octane number of at least 91 RON.
This may reduce engine output and increase fuel
consumption.
If only regular unleaded petrol with an octane
number of 91 RON or lower is available to you on
a long-term basis, you must take your vehicle to a
qualified specialist workshop to have it adapted to
this type of fuel.
Never refuel using fuel with a lower RON.
Further information on fuel can be obtained at a
filling station or a qualified specialist workshop.
