fuel consumption BMW 640I GRAN COUPE 2014 User Guide

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.
Automatic Engine 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.
Using this system can cause certain compo‐
nents of the vehicle to become worn prema‐
turely.
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
consume additional fuel, especially in city and
stop-and-go traffic.
Therefore, switch off these functions if they
are not actually needed.Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
Have the maintenance carried out by your
service center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 208.
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.
The extension of the range that is achieved as
a result can be displayed in the instrument
cluster.
At a glance
The system includes the following
EfficientDynamics functions and displays:▷ECO PRO bonus range, refer to page 181.▷ECO PRO tips driving instruction, refer to
page 182▷ECO PRO climate control, refer to

ECO PRO climate control
"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.
ECO PRO potentialThe percentage of potential savings that can
be achieved with the current configuration is
displayed.
Display in the instrument cluster
Display in the instrument display
When ECO PRO mode is activated, the display
switches to a special configuration.
Some of the displays may differ from the dis‐
play in the instrument cluster.
ECO PRO bonus range An extension of the range can
be achieved by an adjusted driv‐
ing style.
This may be displayed as the
bonus range in the instrument
cluster.
The bonus range is shown in the range display.
The bonus range is automatically reset every
time the vehicle is refueled.
Driving style
In the tachometer, a mark in the bar display in‐
dicates the current efficiency of the driving
style.
Mark in the CHARGE area, arrow 1: display for
energy recovered by coasting or when braking.
Mark in the POWER area, arrow 2: display
when accelerating.
The efficiency of the driving style is shown by
the color of the bar:
▷Blue display: efficient driving style as long
as the mark moves within the blue range.▷Gray display: adjust driving style, e. g. by
backing off the accelerator pedal.
The display switches to blue as soon as all
conditions for fuel-economy-optimized driving
are met.

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 transmission position D is engaged.
The vehicle continues traveling with the engine
idling to reduce fuel consumption. Transmis‐
sion 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 180, driving mode.
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 transmission posi‐
tion D.▷Engine and transmission are at operating
temperature.
Display
Display in the instrument cluster The mark in the bar display be‐
low the tachometer is backlit in
blue and is located at the zero
point. The tachometer approxi‐
mately indicates idle speed.
The coasting point indicator is illuminated at
the zero point during coasting.
Indications on the Control Display
The Coasting driving condition is displayed in
EfficientDynamics Info while this driving mode
is active.
Color code blue, arrow 1, and symbol, arrow 2:

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.
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 Depending on the previous displays, the status
display is displayed when the engine is running
or after the vehicle has been driven for at least
30 minutes.
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 oil level is too low, immediately add 1 US
quart/liter of oil.
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.
General information
A detailed measurement is only possible with
certain engines.
Requirements
▷Automatic transmission: selector lever in
transmission position N or P and accelera‐
tor not depressed.▷Vehicle is on a level road and the engine is
running at operating temperature.
Performing a detailed measurement
In order to perform a detailed measurement of
the engine oil level:
