MOBILITY

Fuel

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.

Super, RON 95.

Minimum grade

Unleaded petrol, RON 91.

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.

System fault

If there is a system fault, a Check Control mes‐

Visit the nearest Service Partner of the manufac‐

turer or another qualified Service Partner or a

specialist workshop.

Reduction agent can be topped up at any time.

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.

Indicating top-up quantity

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
