The engine has knock control. This means that
different petrol grades can be used.
Vehicle equipment
This chapter describes all standard, country-spe‐
cific and special equipment available for the
model series. It may therefore describe equip‐
ment which is not installed in your vehicle, for ex‐
ample on account of the optional equipment se‐
lected or the country variant. This also applies to
safety-relevant functions and systems. Please
comply with the relevant laws and regulations
when using the corresponding functions and
systems.
Safety notes
NOTE
Even small quantities of the wrong fuel or
wrong fuel additives can damage the fuel sys‐
tem and engine. In addition, the catalytic con‐
verter will be permanently damaged. There is a
risk of material damage. Do not use the
following fuel or additives with petrol engines:
▷ Leaded petrol.
Fuel quality
▷ Metallic additives, for example manganese
or iron.
After filling with the wrong fuel, do not press
the start/stop button. Contact a Service Partner
of the manufacturer or another qualified Service
Partner or a specialist workshop.
General
Depending on the region, many filling stations
sell fuel that is adapted to winter or summer con‐
ditions. Fuel that is sold in winter helps with cold
starting, for example.
NOTE
Petrol
Incorrect fuels can damage the fuel system and
engine. There is a risk of material damage. Do
not refuel with fuel with a higher ethanol con‐
tent than recommended. Do not refuel with fuel
containing methanol, for example M5 to M100.
General
For optimal fuel consumption, the petrol should
be sulphurfree or have a low sulphur content.
Fuels labelled on the pump as containing metal
must not be used.
You can fill up with fuels with a maximum ethanol
content of 25 %, for example E10 or E25.
NOTE
Fuel below the specified minimum quality can
adversely affect engine function or lead to en‐
gine damage. There is a risk of material dam‐
age. Do not refuel with petrol below the speci‐
fied minimum quality.
Petrol grade
The engine is designed to run on petrol to DIN
EN 228.

Diesel
Safety note
NOTE
Even small quantities of the wrong fuel or
wrong fuel additives can damage the fuel sys‐
tem and engine. There is a risk of material
damage.
Note the following with diesel engines:
▷ Do not fill up with pure methyl ester.
▷ Only fill up with biodiesel with a maximum
of B7/7 % according to EN 590.
▷ Do not fill up with petrol.
BMW Diesel with
BluePerformance
▷ The vehicle manufacturer recommends
only using diesel additives that have been
classified as suitable.
Principle
After filling with the wrong fuel, do not press
the start/stop button. Contact a Service Partner
of the manufacturer or another qualified Service
Partner or a specialist workshop.
BMW Diesel with BluePerformance reduces ni‐
trous oxides in the diesel exhaust by injecting the
reduction agent AdBlue into the exhaust stream.
In the catalytic converter, this produces a chemi‐
cal reaction that minimises the nitrous oxides.
Diesel quality
The engine is designed to run on diesel fuel to
DIN EN 590 and ASTM D975.
General
The vehicle features a tank system which can be
replenished.
Only refuel with diesel with a sulphur content of
less than 10 ppm.
To start the engine normally, sufficient reduction
agent must be present.
Only fill up with biodiesel with a maximum of
B7/7 % according to EN 590.
AdBlue is a registered trademark of the Verband
der Automobilindustrie e. V. (VDA).
Reduction agent is available at many service sta‐
tions.

AdBlue topping up
BMW recommends having the reduction agent
replenished by a Service Partner as part of a reg‐
ular maintenance schedule.
1. "My Vehicle"
2. "Vehicle status"
3. "AdBlue"
If the filling level is too low, Check Control mes‐
sage is displayed.
If you keep to this maintenance schedule, a sin‐
gle top-up is generally required between the
maintenance appointments.
Displays in the instrument
cluster
Under certain circumstances, for example due to
particularly dynamic driving style or operating the
vehicle with a trailer, topping up between mainte‐
nance appointments more than once may be
necessary.
Reserve level indicator
The reserve level indicator in the instrument
cluster informs you of the remaining distance
which can be travelled with the current level.
As soon as the reserve level indicator is shown in
the instrument cluster, have the reduction agent
topped up, to prevent the vehicle from no longer
being able to be started.
Do not completely use up the displayed dis‐
tance. The engine can no longer be started again
after it was stopped.

Safety notes
Top up quantity
When the reserve level indicator starts, top up at
least 5 litres, approx. 1.3 gal.
WARNING
When the reduction agent container is opened,
small quantities of ammonia vapours can
emerge. Ammonia vapours have a pungent
smell and irritate the skin, mucous membranes
and eyes. There is a danger of injury. Do not in‐
hale ammonia vapours. Do not allow reduction
agent to come into contact with clothing, skin
or eyes, and do not swallow it. Keep children
away from reduction agents.

Precise top-up quantity is shown on Control Dis‐
play.

Replenishing reduction agent at the
pump dispenser
WARNING
Service products, for example oils, greases,
coolants and fuels, can contain substances that
are harmful to health. There is a danger of in‐
jury or even death. Please comply with the in‐
structions on the containers. Do not allow serv‐
ice products to come into contact with clothing,
skin or eyes. Do not pour service products into
other bottles. Keep service products out of the
reach of children.
General
When refuelling, insert the filler nozzle fully into
the filler neck. Lifting the filler nozzle during refu‐
elling results in the following:
▷ The supply of fuel is stopped too soon.
▷ Overflow of reducing agent.
The tank for the reducing agent is full when the
filler nozzle cuts out for the first time.
Depending on the filler nozzle, the tank for the
reducing agent may not be filled completely.
NOTE
The constituents of reduction agent are highly
aggressive. There is a risk of material damage.
Avoid contact of reduction agent with surfaces
of the vehicle.
Please comply with the safety regulations dis‐
played at filling stations.
Suitable AdBlue
▷ AdBlue of standard ISO 22241-1
AdBlue is available in various containers. Prefera‐
bly use the special bottle recommended by
BMW. With this bottle and its special adapter,
AdBlue can comfortably be topped up.
At many service stations, reduction agent is
available at a special pump dispenser. Reducing
