Refueling
Always switch off the engine before refu-
eling; otherwise, fuel cannot be added to
the tank and a message will be displayed.<
Take all precautionary measures and
observe all applicable regulations when
handling fuel. Do not carry any spare fuel con-
tainers in your vehicle. They can develop a leak
and cause an explosion or cause a fire in the
event of an accident.<
Fuel filler flap
Opening
1.Open the fuel filler flap. To do so, lightly
press the rear edge.
2.Turn the gas cap counterclockwise.
3.Place the gas cap in the bracket attached to
the fuel filler flap.
Closing
Fit the cap and turn it clockwise until you clearly
hear a click.
Do not pinch the band attached to the
cap; otherwise, the cap cannot be closed
properly and fuel vapors can escape. A mes-
sage will be displayed if the gas cap is loose or
missing.<
Manually releasing the fuel filler flap
In the event of a malfunction, you can release
the fuel filler flap manually:
Sedan
1.Remove the cover from the right-hand side-
wall of the cargo area.
2.Pull the knob with the fuel pump symbol.
The fuel filler flap is released.
Sports Wagon
1.Fold up the cargo area floor panel.
2.Remove the cover from the right-hand side-
wall of the cargo area. To do so, turn the
screws, arrows 1, 90° and take out the

Observe the following when refueling
When handling fuels, follow the safety
instructions provided at filling stations;
otherwise, there is a risk of personal injury or
property damage.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as that would lead
to
>Premature pump shutoff
>Reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<
Gasoline engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
Diesel engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 1.7 US gallons/6.5 liters.
Fuel specifications
Gasoline engine: required fuel
Do not refuel with leaded fuel; otherwise,
the catalytic converter will be damaged.
Do not fill the tank with E85, i.e. fuel containing
85Ξ ethanol, nor with FlexFuel. Otherwise, the
engine and fuel supply system will be dam-
aged.<
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>323i, 328i/xDrive: 87>335i/xDrive: 89.
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.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an
equivalent amount of cosolvent, will not void the
applicable warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<
BMW Advanced Diesel: required fuel
Ultra-low sulfur diesel
The engine of your BMW is designed for diesel
with low sulfur content:
Ultra-low sulfur diesel ASTM D 975-07a.
Refuel with ultra-low sulfur diesel only.
The percentage of biodiesel in the fuel
must not exceed 5 %; this type of fuel is referred
to as B5. Do not refuel with gasoline. If you have
accidentally refueled with the wrong fuel, e.g.
with gasoline, do not start the engine; other-
wise, engine damage may occur.<

Refueling
198 If you have refueled with the wrong fuel, contact
your BMW center.
The filler neck is designed for refueling at
diesel fuel pumps.
If the filler nozzle cannot be inserted into your
BMW's filler pipe, please ensure that you are
refueling at a diesel fuel pump and that it is
equipped with a diesel filler 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.
For more information on BMW Roadside Assis-
tance, refer to page237.<
Winter diesel
To ensure that the diesel engine remains oper-
ational in the winter, please use winter diesel,
which is available at gas stations during winter
months. The fuel filter heating system, included
a s a s t a n d a r d f e a t u r e , p r e v e n t s d i s r u p t i o n o f t h e
fuel supply while driving.
Do not add additives, including gasoline;
otherwise, engine damage may occur.<
BMW Advanced Diesel
The concept
BMW Advanced Diesel reduces nitrogen oxide
in the diesel emissions of your vehicle by means
of a mechanism that injects diesel exhaust fluid,
a reduction agent, into the exhaust tract. A
chemical reaction occurs in the catalytic con-
verter that minimizes the nitrogen oxide con-
tent.
To be able to start the engine as usual, a suffi-
cient amount of diesel exhaust fluid must be
present in a separate reservoir.
Warming the system
To warm the system to its operating tempera-
ture after starting with a cold engine, the auto-
matic transmission delays shifting to the next
higher gear, if necessary.
Reserve display
A display in the instrument cluster informs you
about the remaining distance you can drive with
the fluid remaining in the reservoir.
-
The reserve display appears beginning at
approx. 1,000 miles/1,600 km before the sup-
ply is used up.
When this reserve display appears in the
instrument cluster, have diesel exhaust
fluid refilled to avoid not being able to start the
engine.<
Diesel exhaust fluid at the minimum
level
Even if the display indicates -- mls, the engine
continues running if it is not switched off and if
all other requirements continue to be met, e.g. a
sufficient supply of fuel.
Do not drive to the end of the indicated
distance. Otherwise, it will not be possible
to start the engine again after switching it off.<
