Controls overview
72
Coolant temperature
A warning lamp will come on if the coolant,
and therefore the engine, becomes too hot.
In addition, a message will appear on the
Control Display.
Check coolant level, refer to page230.
Energy Control*
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a
message appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 16.1 gallons/
61 liters.
You can find information on refueling on
page203.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control Dis-
play.
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.<

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
y o u a r e u s i n g , w e r e c o m m e n d t h a t y o u r e s p o n d
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
m u s t n o t e x c e e d 5 % ; t h i s t y p e o f f u e l i s r e f e r r e d
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.<
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 page246.<
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
as a standard feature, prevents disruption of the
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
converter that minimizes the nitrogen oxide
content.
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.<
Wrong fluid
A warning lamp lights up:
The wrong fluid was filled into the res-
ervoir.
Please contact your BMW center.
Having the diesel exhaust fluid refilled
Diesel exhaust fluid is refilled by your BMW
center during regular service. If the service
intervals are adhered to, it generally does not
need to be refilled between service appoint-
ments.
Under certain conditions, e.g. especially fre-
quent accelerations or operation of the vehicle
at high altitudes, it may become necessary to
refill the fluid between service appointments.
When this reserve display appears in the instru-
ment cluster, have diesel exhaust fluid refilled to
avoid not being able to start the engine.
You can have the fluid refilled by a BMW center.
Diesel exhaust fluid at low
temperatures
Because of its physical properties, it may
be necessary to refill diesel exhaust fluid
between regular service appointments at tem-
peratures below +237/-56.
The need to add fluid is indicated by the reserve
display in the instrument cluster, refer to
page204.<
Refilling diesel exhaust fluid in
exceptional cases
To be able to reach the next BMW center, you
can refill diesel exhaust fluid yourself while
adhering to the following warnings.
Do not come into contact with diesel
exhaust fluid as it can lead to skin or eye
irritations. Wear goggles and gloves, if neces-
sary. Follow the safety instructions on the bot-
tle.
Vapors with a sharp odor can escape from the
bottle or container when it is opened. Before
refilling, completely close the windows and
doors of the vehicle to prevent the vapors from
intruding into the interior. If handling diesel
exhaust fluid in an enclosed area, ensure that
the room is well ventilated.
After handling diesel exhaust fluid, wash your
hands thoroughly; otherwise, for example, inad-
vertently touching your eyes may lead to eye
irritations.
If eye irritations occur, rinse the eyes thoroughly
with water and consult a physician if necessary.
If diesel exhaust fluid comes into contact with
the surface of your vehicle, rinse the affected
areas with water to prevent surface damage.
Keep diesel exhaust fluid away from children.<
Suitable diesel exhaust fluid
>Preferred: BMW Diesel Exhaust Fluid.
Diesel exhaust fluid can be refilled conve-
niently with this bottle and its special
adapter.
>Alternatively: NOx reduction agent AUS 32
You can obtain diesel exhaust fluid from your
BMW center.
