If you have accidentally refueled with the

Do not switch on the ignition.

If the available fuel is not sufficiently low in sul‐
fur, this can produce unpleasant odors.

number specified in the instruction label in the
fuel filler flap ( page 161).

If you want maximum engine output: only
refuel with unleaded premium grade gasoline
with an octane number of at least 91 AKI/
95 RON.
As a temporary measure, if the recommended
fuel is not available, you may also refuel with
unleaded regular gasoline with at least 87 AKI/
91 RON. This may reduce engine performance
and increase fuel consumption.
Never refuel using gasoline with an even lower
RON.
