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.◀
Diesel
CAUTION
Even small amounts of wrong fuel or
wrong fuel additives can damage the fuel sys‐
tem and the engine. There is risk of property
damage.
Observe the following for diesel engines:
▷ Use only Ultra-Low Sulfur Diesel. Maxi‐
mum content of biodiesel: 5 %, B5.
▷ Do not use rapeseed methyl ester RME.
▷ Do not use biodiesel above 5 %, B5.
▷ Do not use gasoline.
▷ No diesel additives.

Fuel
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.◀
Ultra-Low Sulfur Diesel
The engine of your BMW is designed for diesel
with low sulfur content:
Ultra-Low Sulfur Diesel ASTM D 975-xx.
xx: comply with the current standard in each
case.
Use only Ultra-Low Sulfur Diesel.
The fraction of biodiesel in the fuel must not
exceed 5%, referred to as B5. Do not use gas‐
oline. If you do fill the tank with the wrong fuel,
e.g., gasoline, do not start the engine as this
may damage the engine.
In the case of incorrect refueling, contact a
dealer's service center or another qualified
service center or repair shop or Roadside As‐
sistance.
If the fuel pump nozzle does not fit in the filler
pipe of your BMW, please check to ensure that
you are refueling at a diesel fuel pump that is
equipped with a diesel fuel pump nozzle.
In the event the Ultra-Low Sulfur Diesel fuel
cannot be fully inserted into the fuel filler neck,
please contact BMW Roadside Assistance for
instructions on how to add fuel.
