If the available fuel is not sufficiently low in sulfur,
it may produce unpleasant odors.
Only refuel with fuel that has at least the octane
number specified in the information label on the
fuel filler flap. Otherwise, engine output may be
reduced and fuel consumption increased.
For maximum engine output: Only refuel using
premium-grade unleaded gasoline with at least
91 AKI/95 RON.
If the recommended fuel is not available, you may
also temporarily use regular unleaded gasoline
with an octane number of at least 87 AKI/
91 RON. This may reduce engine output and
increase fuel consumption.
Never refuel using gasoline with an even lower
RON.
