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.◀

Closing  
The filler neck is designed for refueling at die‐  
sel fuel pumps.  
1. Fit the lid and turn it clockwise until you  
clearly hear a click.  
2. Close the fuel filler flap.

This chapter describes all standard, country-

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.  
Lamp white: refill with re‐  
duction agent at the next  
opportunity.  
Lamp yellow: not enough re‐  
duction agent present. The  
remaining range is displayed  
in the instrument cluster. Im‐  
mediately refill with reduc‐  
tion agent, refer to  
Winter diesel  
To ensure that the diesel engine remains op‐  
erational in the winter, use winter diesel.  
It is available at gas stations during winter  
months.

agent. The engine will con‐  
tinue to run as long as it is  
not switched off and all  
other operating conditions  
are satisfied; sufficient fuel,

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‐  
der + 23 ℉/- 5 ℃. In this case, add reducing  
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‐  
play is displayed only until the fill level can be  
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  
Avoid contact of reduction agent with  
surfaces of the vehicle; otherwise, damage  
could occur.◀  
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.
