* NOTE Damage caused by the wrong fuel
Even small amounts of the wrong fuel could
result in damage to the fuel system, the
engine and the emission control system.
Only refuel with low-sulfur spark-ignition
#
engine fuel.
This fuel may contain up to 10% ethanol by vol-
ume. Your vehicle is suitable for use with E10
fuel.
Never refuel with one of the following fuels:
diesel
R
Gasoline with more than 10% ethanol by
R
volume, e.g. E15, E85, E100
Gasoline with more than 3% methanol by
R
volume, e.g. M15, M30, M85, M100
Gasoline with additives containing metal
R
If you have accidentally refueled with the
wrong fuel:
Do not switch on the vehicle.
#
Consult a qualified specialist workshop.
#
If the available fuel is not sufficiently low in sulfur,
it may produce unpleasant odors.
Refuel using only premium-grade unleaded gaso-
line of at least 91 AKI/95 RON.
As a temporary measure, if the recommended fuel
is not available, you may also use regular unlea-
ded gasoline. When doing this, note the octane
number on the vehicle on the information label on
the fuel filler flap (see the vehicle Operator's Man-
ual). Filling up with regular unleaded gasoline can
reduce engine output and increase fuel consump-
tion.
Never refuel using gasoline of an even lower RON.
* NOTE Premature engine wear through
unleaded regular gasoline
Impairment of the longevity and performance
of the engine.
If unleaded premium grade gasoline is unavail-
able and you have to refuel using unleaded
regular gasoline:
Only fill the fuel tank to half full with
#
unleaded regular gasoline and refill as
soon as possible with unleaded premium
grade gasoline.
Do not drive at the maximum design
#
speed.
Avoid sudden acceleration and engine
#
speeds over 3000 rpm.
