Refueling Fuel specificationTo unlock the filler door in the event of a
central locking system failure, refer to
page152.a
When handling fuel, comply with
the safety regulations displayed by gas
stations.cUnleaded gasoline only.
Minimum octane requirement: 89 AKI
BMW engines are equipped with knock
sensors and automatically adapt to op-
erate with fuels of different octane rat-
ings, as long as the minimum octane
requirement is met.
Higher octane fuels will provide in-
creased performance and fuel econ-
omy, while the use of gasoline with a
lower octane rating will have an adverse
effect.
a
Never use leaded fuel, as it would
cause permanent damage to both the
catalytic converter and the engine-man-
agement systemÕs oxygen sensors.c
AKI = Anti Knock Index
