Vehicle features and options
This 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.
3. Place the tank lid in the bracket attached to
the fuel filler flap.
Hints
Observe the fuel recommendation, refer to
page 192, prior to refueling.
Refuel promptly
Refuel no later than at a range of
30 miles/50 km or engine operation might fail
and damage might occur.◀

US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
Do not use a fuel with a higher percent‐
age of ethanol
Do not use a fuel with a higher ethanol per‐
centage than recommended or one with other
types of alcohol, e.g. M5 to M100; otherwise
this could damage the engine and fuel supply
system.◀
Fuel recommendation
Note
Recommended fuel grade
BMW recommends AKI 91.
General fuel quality
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
Minimum fuel grade
BMW recommends AKI 89.
performance. Switch gas stations or use a
brand name fuel with a higher octane rating.◀
Minimum fuel grade
Do not use any gasoline below the mini‐
mum fuel grade as this may impair engine per‐
formance.◀
Gasoline
For the best fuel efficiency, the gasoline
should be sulfur-free or very low in sulfur con‐
tent.
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.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.
Fuel quality
Refuel only with unleaded gasoline with‐
out metallic additives.
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.
Do not refuel with any leaded gasoline or gaso‐
line with metallic additives, e. g. manganese or
iron, as this can cause permanent damage to
the catalytic converter and other compo‐
nents.◀
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‐
Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.

gine deposits, it is highly recommended to
purchase gasoline from Top Tier retailers.
Do not add any diesel additives
Do not add additives, including gasoline;
otherwise, engine damage may occur.◀
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
BMW Advanced Diesel
Diesel
The concept
Low-Sulfur Diesel
BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel emissions by injecting diesel
exhaust fluid reducing agent into the exhaust
system. A chemical reaction takes place inside
the catalytic converter that minimizes nitrogen
oxides.
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.
The vehicle has a tank that can be refilled.
Use only Ultra-Low Sulfur Diesel.
To be able to start the engine as usual, there
must be an adequate reducing agent.
The fraction of biodiesel in the fuel must
not exceed 5 %, referred to as B5. Do not use
gasoline. If you do fill the tank with the wrong
fuel, e.g., gasoline, do not start the engine as
this may damage the engine.◀
Reducing agent is added by the service center.
Warming up the system
In order to warm the engine up to its operating
temperature after a cold start, the Steptronic
transmission may subsequently shift up to the
next higher gear.
After adding the wrong fuel, contact your serv‐
ice center or Roadside Assistance.
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.
Displays in the instrument cluster
Reserve indication
This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.
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.
For additional information regarding Roadside
Assistance, refer to Owner's Manual for Navi‐
gation, Entertainment and Communication.

Due to its physical properties, it is possible
that the reducing agent may also need to be
replenished between regular maintenance ap‐
pointments if it is exposed to temperatures un‐

agent only immediately before driving off.
The need to replenish it is indicated by the Re‐
serve display in the instrument cluster.
Engine does not start
At temperatures below + 12 ℉/- 11 ℃, the fill‐
ing level cannot be measured in some cases.
Do not continue driving to the limit of the
remaining travel distance. Otherwise, you will
not be able to restart the engine after switch‐
ing it off. In certain cases, this could cause
safety to be impaired.◀
After adding reducing agent, the Reserve Dis‐

measured again.
Replenishing Diesel exhaust fluid
yourself in exceptional cases
Filling with an incorrect fluid
You can replenish reducing agent yourself in
exceptional cases, e.g., to get to the service
center.
A Check Control message is displayed when
an incorrect fluid is added.
After adding the incorrect fluid, contact your
service center.
Avoid contact with Diesel exhaust fluid
Do not come into contact with the reduc‐
ing agent. Otherwise, skin or eye irritations
may result.◀
System defect
A Check Control message is displayed when
there is a system defect.
Handling Diesel exhaust fluid
When working with reducing agent in
closed spaces, ensure good ventilation. When
the bottle or container is opened, acrid smell‐
ing fumes may eslide.◀
Have the diesel exhaust fluid
replenished
The reducing agent is added by the service
center within the context of regular mainte‐
nance.
Keeping Diesel exhaust fluid out of reach
of children
It may be necessary to have the fluid replen‐
ished several times under particular circum‐
stances, e.g., if the vehicle is driven in a partic‐
ularly sporty style or if it is driven at high
altitudes.
Keep reducing agent out of reach of children.◀
Avoid contact with surfaces

The reducing agent must be replenished as
soon as the reserve display appears in the in‐
strument cluster to avoid not being able to re‐
start the engine.
