2015 BMW 4 SERIES CONVERTIBLE range

accelerating, shift up before reaching high en‐
gine 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.
If necessary, observe the gear shift indicator of
the vehicle, refer to page 83.
Use coasting When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
For going downhill take your foot off the accel‐
erator 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.
Reel off these functions if they are not needed.
The ECO PRO driving program supports the
energy conserving use of comfort features.
These functions are automatically deactivated
partially or completely.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 205.
ECO PRO
The concept
ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort features, e. g. the cli‐
mate 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.
In addition, context-sensitive instructions are
displayed to assist with an optimized fuel con‐
sumption driving style.
The achieved extended range is displayed in
the instrument cluster as bonus range.Seite 174Driving tipsSaving fuel174

This function is only available in ECO PRO
mode.
ECO PRO climate control
"ECO PRO climate control"
Climate control is set to be fuel-efficient.
By making a slight change to the set tempera‐
ture, or slowly adjusting the rate of heating or
cooling of the car's interior, fuel consumption
can be economized.
The mirror heating is made available when out‐
side temperatures are very cold.
ECO PRO potential Shows potential savings with the current set‐
tings in percentages.
Display in the instrument cluster
ECO PRO bonus range An adjusted driving style helps
you extend your driving range.
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.Seite 175Saving fuelDriving tips175

Efficiency displayDisplay in the instrument clusterDisplay in the instrument cluster with extended
range
A mark in the efficiency display informs about
the current driving style.
Mark in the area of arrow 1: display of the en‐
ergy recovered by coasting or when braking.
Mark in the area of arrow 2: display when ac‐
celerating.
Your driving style's efficiency is shown by the
bar's color:
▷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-efficiency-optimized driving
are met.
ECO PRO tip, driving tip
The arrow indicates that the driving
style can be adjusted to be more fuel
efficient by backing off the accelerator
for instance.
Note The efficiency display and ECO PRO tips in the
instrument cluster appear when the ECO PRO
display is activated.

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 set. 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 you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 174, 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 proactively driving style helps the driver to
use the function as often as possible and sup‐
ports the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷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 met:
▷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.
The driving status Coast can be influenced
with the shift paddles.

ECO PRO driving style analysis
The concept
In this situation the system helps develop an
especially efficient driving style and to con‐
serve fuel.
For this purpose, the driving style is analyzed.
The assessment is done in various categories
and is displayed on the Control Display.
Using this indication, the individual driving
style can be oriented toward conserving fuel.
The last fifteen minutes of a trip are evaluated.
The range of the vehicle can be extended by
an efficient driving style.
This gain in range is displayed as a bonus
range in the instrument cluster and on the
Control Display.

analysis1.Activate ECO PRO.2."EfficientDynamics"3. Select the symbol.
Display on the Control Display
The display of the ECO PRO driving style anal‐
ysis consists of a symbolized route and a
lookup table.
The road symbolizes the efficiency of the driv‐
ing style. The more efficient the driving style,
the smoother the depicted route becomes, ar‐
row 1.
The table of values contains stars. The more
efficient the driving style, the more stars are in‐
cluded in the table and the faster the bonus
range increases, arrow 2.
If, on the other hand, the driving style is ineffi‐
cient, a wavy road and a reduced number of
stars is displayed.
To assist with an efficient driving style, ECO
PRO tips are displayed during driving.
