2013 BMW 640I CONVERTIBLE fuel consumption

The gear shift indicator of your vehicle indicates
the most fuel efficient gear.
Use coasting conditions
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 ac‐
celerator 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 au‐
tomatically 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 re‐
duced. Savings can begin within a few seconds
of switching off the engine.
Using this system can cause certain compo‐
nents of the vehicle to become worn prema‐
turely.
Iin addition, fuel consumption is also determined
by other factors, such as driving style, road con‐
ditions, maintenance or environmental factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear win‐
dow defroster require a lot of energy and con‐
sume 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 serv‐
ice center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 195.
ECO PRO
The concept
ECO PRO supports a driving style that saves on
fuel consumption. For this purpose, the engine
control and comfort functions, e. g. the climate
control output, are adjusted.
In addition, context-sensitive instructions can
be displayed that assist in driving in a manner
that optimizes fuel consumption.
The extension of the range that is achieved as a
result can be displayed in the instrument cluster.
Activating ECO PRO Press button repeatedly until ECO PRO
is displayed in the instrument cluster.
Display in the instrument cluster
ECO PRO bonus range An extension of the range can be
achieved by an adjusted driving
style.
This may be displayed as the bo‐

ter.Seite 170Driving tipsSaving fuel170

The climate control is adjusted to be fuel-effi‐
cient.
By making a slight change to the set tempera‐
ture, or adjusting the rate of heating or cooling
of the passenger compartment fuel consump‐
tion can be economized.
The output of the seat heater is also reduced.
ECO PRO Potential
The percentage of potential savings that can be
achieved with the current configuration is dis‐
played.

Engine oilVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
General information
Engine oil consumption depends on driving
style and driving conditions, e.g., if your driving
style is very sporty engine oil consumption will
be considerably greater.
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 appears 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
▷Manual transmission: shift lever in neutral
position, clutch and accelerator pedals not
depressed.▷Automatic transmission: selector lever in
transmission position N or P and accelerator
not depressed.▷Vehicle is on a level road and the engine is
running at operating temperature.Seite 191Engine oilMobility191
