FuelVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Fuel recommendation General information
Depending on the region, many gas stations
sell fuel that has been customized to winter or
summer conditions. Fuel that is available in
winter helps make a cold start easier, e.g.
Information CAUTION
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, for instance poor engine start-
up behavior, poor handling and/or poor
performance. There is risk of property damage.
In case of engine problems, switch gas sta‐
tions or use a brand name fuel with a higher
octane rating.◀
Gasoline For the best fuel efficiency, the gasoline
should be sulfur-free or very low in sulfur con‐
tent.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.CAUTION
Even small amounts of wrong fuel or
wrong fuel additives can damage the fuel sys‐
tem and the engine. Furthermore, the catalytic
converter is permanently damaged. There is
risk of property damage. Do not refuel or add
the following in the case of gasoline engines:▷Leaded gasoline.▷Metallic additives, e.g. manganese or iron.
Do not press the Start/Stop button after refuel‐
ing the wrong fuel. Contact a dealer’s service
center or another qualified service center or re‐
pair shop.◀
Fuels with a maximum ethanol content of
25 %, i. e. E10 or E25, may be used for refuel‐
ing.
Ethanol should satisfy the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
CAUTION
Wrong fuels can damage the fuel system
and the engine. There is risk of property dam‐
age. Do not use a fuel with a higher ethanol
percentage than recommended or one with
other types of alcohol, e.g. M5 to M100.◀
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
CAUTION
Fuel that does not comply with the mini‐
mum quality can compromise engine function
or cause engine damage. There is risk of prop‐

erty damage. Do not fill with fuel that does not
comply with the minimum quality.◀
If you use gasoline with this minimum AKI Rat‐
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
CAUTION
The use of poor-quality fuels may result
in harmful engine deposits or damage. Addi‐
tionally, problems relating to drivability, start‐
ing and stalling, especially under certain envi‐
ronmental conditions such as high ambient
temperature and high altitude, may occur.
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI num‐
ber — for a few tank fills. To avoid harmful en‐
gine deposits, it is highly recommended to
purchase gasoline from Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀Seite 253FuelMobility253
