2014 BMW 3 SERIES SEDAN fuel consumption

Saving fuelVehicle equipmentAll 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.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on the envi‐
ronmental impact.
Remove unnecessary cargoAdditional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following
use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information Tires can affect fuel consumption values in
various ways, for instance fuel consumption
can be influenced by the size of the tires.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.Seite 168Driving tipsSaving fuel168

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

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.

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is engaged.
The vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as the brake or accelerator pedal is
depressed, the engine is automatically coupled
to the transmission again.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 169, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A forward-looking driving style helps the driver
to use the function as often as possible and supports the fuel-conserving effect of coast‐
ing.
Safety mode
The function is not available if one of the fol‐
lowing conditions is satisfied.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are satisfied:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.Seite 172Driving tipsSaving fuel172

Engine oilVehicle 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.
General information The engine oil consumption is dependent on
the driving style and driving conditions. When
a sporty driving style is used, the engine oil
consumption, for example, is clearly higher.
Therefore, regularly check the engine oil level
after refueling.
Depending on its engine, the vehicle is equip‐
ped with electronic oil measurement or meas‐
uring is done with a dipstick.
The electronic oil measurement has two meas‐
uring principles.▷Status display▷Detailed measurement
Checking the oil level
electronically
Status display
The concept The oil level is monitored electronically during
driving and shown on the Control Display.
If the oil level reaches the minimum level, a
check control message is displayed.
Requirements
A current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip
is displayed.
With frequent short-distance trips, regularly
perform a detailed measurement.
Displaying the oil level1."Vehicle Info"2."Vehicle status"3. "Engine oil level"
Oil level display messages
Different messages appear on the display de‐
pending on the oil level. Pay attention to these
messages.
If the engine oil level is too low, within the next
125 miles/200 km Add oil, refer to page 199.
Engine oil level too low
Add oil immediately; otherwise, an insuf‐
ficient amount of engine oil could result in en‐
gine damage.◀
Take care not to add too much engine oil. Too much engine oil
Have the vehicle checked immediately;
otherwise, surplus oil can lead to engine dam‐
age.◀
Detailed measurement
The concept
In the detailed measurement the oil level is
checked and displayed via a scale.
During the measurement, the idle speed is in‐
creased somewhat.
