LoadingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Hints Overloading the vehicle
To avoid exceeding the approved carry‐
ing capacity of the tires, never overload the ve‐
hicle. Overloading can lead to overheating and
increases the rate at which damage develops
inside the tires. This could result in a sudden
loss of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be dam‐
aged.◀
Heavy and hard objects
Do not stow any heavy and hard objects
in the passenger compartment without secur‐
ing them; otherwise, they may present a dan‐
ger to occupants, e.g., during braking and eva‐
sive maneuvers.◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to thevehicle and unstable driving situations
may result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.Seite 165LoadingDriving tips165

Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly.
When accelerating, shift up before reaching
high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
The gear shift indicator of your vehicle indi‐
cates the most fuel efficient gear.
Use coasting When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
On a downhill gradient, take your foot off the
accelerator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Auto Start/Stop function The Auto Start/Stop function of your vehicle
automatically switches off the engine during a
stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,road conditions, maintenance or environmental
factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
reduce the range, especially in city and stop-
and-go traffic.
Therefore, switch off these functions if they
are not actually needed.
The ECO PRO driving program supports the
energy conserving use of comfort functions.
These functions are automatically deactivated
partially or completely.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 202.
ECO PRO
The concept ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort functions, e. g. the
climate control output, are adjusted.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
the D selector lever position. The vehicle con‐
tinues traveling with the engine idling to re‐
duce fuel consumption. Selector lever position
D remains engaged.Seite 169Saving fuelDriving tips169

In addition, context-sensitive instructions can
be displayed that assist in driving in a manner
that optimizes fuel consumption.
In the instrument display, the extension of the
range achieved by this can be displayed as a
bonus range.
At a glance The system includes the following
EfficientDynamics functions and displays:▷ECO PRO bonus range, refer to page 170.▷ECO PRO tips driving instruction, refer to

"ECO PRO climate control"
The climate control is adjusted to be fuel-effi‐
cient.
By making a slight change to the set tempera‐
ture, or slowly adjusting the rate of heating or
cooling of the passenger compartment, fuel
consumption can be economized.
The outputs of the seat heater and the exterior
mirror heating are also reduced.
The exterior mirror heating is made available
when outside temperatures are very cold.

Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
Diesel
Low-Sulfur Diesel
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.
Use only Ultra-Low Sulfur Diesel.
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.◀
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.
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 infor‐
mation on BMW Roadside Assistance, refer to
page 216.
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.
The fuel filter heating system, included as a
standard feature, prevents disruption of the
fuel supply while driving.
Do not add any diesel additives
Do not add additives, including gasoline;
otherwise, engine damage may occur.◀
BMW Advanced Diesel
The concept 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 vehicle has a tank that can be refilled.
To be able to start the engine as usual, there
must be an adequate reducing agent.
Reducing agent is added by the service center.
Warming up the systemIn order to warm the engine up to its operating
temperature after a cold start, the automatic
transmission may subsequently shift up to the
next higher gear.
Displays in the instrument cluster
Reserve display
This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.
The reserve display is shown
starting at a remaining range of
approx. 1,000 miles/1,600 km.
