Notes on fuel grades for vehicles with a gas‐
oline engine
Observe the notes on operating fluids .
* 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 unleaded
#
fuel.
This fuel may contain up to 10% ethanol by
volume. 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 ignition.
#
Consult a qualified specialist workshop.
#
Only refuel using unleaded premium grade gaso‐
line with at least 91 AKI/95 RON.
If the available fuel is not sufficiently low in sul‐
fur, this can produce unpleasant odors.
As a temporary measure, if the recommended
fuel is not available, you may also use unleaded
regular gasoline which has at least the octane
number specified in the instruction label in the
fuel filler flap . This may reduce engine perform‐
ance and increase fuel consumption.
Never refuel using gasoline with a lower RON.
* NOTE Premature wear caused by unlea‐
ded regular gasoline
Unleaded regular gasoline can cause the
engine to wear more quickly and impair lon‐
gevity and performance.
If unleaded premium grade gasoline is
unavailable 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 pre‐
mium grade gasoline.
Do not drive at the maximum speed.
#
Avoid sudden acceleration and engine
#
speeds over 3,000 rpm.
