Vehicle equipment
Closing windows and the
Glass Roof
This chapter describes all standard, country-spe‐
cific and special equipment available for the
model series. It may therefore describe equip‐
ment which is not installed in your vehicle, for ex‐
ample on account of the optional equipment se‐
lected or the country variant. This also applies to
safety-relevant functions and systems. Please
comply with the relevant laws and regulations
when using the corresponding functions and
systems.
An open Glass Roof or open window increase
drag and consequently reduce the range.
Tyres
General
Tyres can have differing effects on consumption.
For example consumption can be affected by
tyre size.
General
Check tyre inflation pressure
regularly
Check and, if necessary, correct the tyre inflation
pressures at least twice a month and before set‐
ting off on a longer journey.
The vehicle possesses wide-ranging technolo‐
gies for reducing consumption and emission lev‐
els.
Fuel consumption depends on various factors.
A number of measures, such as a moderate driv‐
ing style and regular maintenance, can influence
fuel consumption and reduce the burden on the
environment.
Insufficient tyre inflation pressure increases roll‐
ing resistance and consequently fuel consump‐
tion and tyre wear.
Drive off immediately
Remove unnecessary loads
Do not warm up the engine with the vehicle at a
standstill; it is preferable to set off straight away,
driving at moderate engine speeds.
Extra weight increases fuel consumption.
This brings the cold engine up to operating tem‐
perature as quickly as possible.
Remove add-on parts after
use
If no longer required, remove auxiliary mirrors,
roof racks and rear-mounted racks after use.
Think ahead
Add-on parts on the vehicle interfere with its aer‐
odynamic performance and increase fuel con‐
sumption.
Anticipating the road situation and adopting a
smooth driving style will reduce fuel consump‐
tion.
Avoid accelerating and braking unnecessarily.
238
Saving fuel
DRIVING HINTS
Keep an appropriate distance from the vehicle
ahead.
Switch off functions which
are not currently required
Functions such as seat heating or rear window
heating require a great deal of energy and re‐
duce the range, especially in city traffic and stop-
and-go traffic.
Avoid high engine speeds
Driving at low engine speeds lowers fuel con‐
sumption and wear.
Switch these functions off if they are not re‐
quired.
Pay attention to the shift point indicator, see
page 137, in the vehicle, if fitted.
The ECO PRO drive mode supports energy-sav‐
ing use of comfort functions. These functions are
automatically deactivated wholly or partially.
Make use of overrun mode
When approaching a red traffic light, take your
foot off the accelerator and allow the vehicle to
roll.
Have maintenance work
carried out
On downward stretches, take your foot off the
accelerator and allow the vehicle to roll.
Have the vehicle serviced regularly to achieve
optimal economy and lifetime. BMW recom‐
mends having maintenance work carried out by a
BMW Service Partner.
The fuel supply is interrupted in overrun mode.
Switch off the engine if
stopping for longer periods
Please also see the BMW Maintenance System,
see page 280.
Stopping the engine
When you stop the vehicle for longer periods, for
example at traffic lights, railway crossings or in
traffic jams, switch off the engine.
ECO PRO
Principle
ECO PRO supports an efficient driving style. To
do this, the engine management and comfort
functions, such as for example the air condition‐
ing power, are adjusted.
Auto Start Stop function
The Auto Start Stop function of the vehicle shuts
off the engine automatically during a stop.
The engine is disconnected from the gearbox in
selector lever position D under certain circum‐
stances. The vehicle rolls when idling to optimise
consumption. Selector lever position D remains
engaged.
If the engine is switched off and then started
again, the fuel consumption and emissions are
reduced compared with a permanently running
engine. Savings can be made just by stopping
the engine for a few seconds.
In addition, messages to help you to drive with
maximum efficiency can also be displayed in real
time.
Fuel consumption also depends on other factors,
such as driving style, road condition, mainte‐
nance or environmental factors, for example.
In the instrument cluster, the extension of the
range achieved as a result can be displayed as a
bonus range.

In the revolution counter, a long
arrow up to the zero point of the
efficiency display shows that a
section of road in front has been
detected.
Coasting
Principle
The engine is automatically disconnected from
the gearbox in selector lever position D under
certain circumstances. The vehicle continues to
roll in idle to reduce consumption. Selector lever
position D remains engaged.
Display on the Control Display
This vehicle condition is called coasting.
As soon as the brake or accelerator pedal is
pressed, the engine is automatically connected
again.
General
Coasting is a component of ECO PRO drive
mode.
The Control Display shows if there is a corre‐
sponding section of the route.
Coasting is automatically activated by calling up
the ECO PRO drive mode via the Driving Experi‐
ence Control.
Call up driving style analysis display:
A precautionary driving style helps to use the
function as often as possible and supports the
consumption-reducing effect of coasting.

Driving style analysis
Principle
The function helps you to develop a particularly
efficient driving style and to save fuel.
Display on the Control Display
In EfficientDynamics, the coasting drive state is
shown during the journey.
The route covered in the coasting drive state is
displayed in the consumption history. The coun‐
ter reading is reset before the start of each jour‐
ney.
To do this, the driving style is analysed. The eval‐
uation is performed in various categories and is
shown on the Control Display.
Using this display, the individual driving style can
be adjusted to save fuel.
The last 15 minutes of a journey are evaluated.
The range of the vehicle can be increased by
adopting an efficient driving style.
This gain in range is shown as a bonus range on
the instrument cluster and Control Display.
Operating requirements
The function is available in ECO PRO drive
mode.

Display on the Control Display
The display of the ECO PRO driving style analy‐
ser consists of a symbolised road and a perform‐
ance table.
The road symbolises the efficiency of the driving
style. The more efficient the driving style, the
more evenly the route is illustrated, arrow 1.
The performance table contains stars. The more
efficient the driving style, the more stars are con‐
tained in the table and the faster the bonus range
increases, arrow 2.
On the other hand, if the driving style is ineffi‐
cient, a bumpier road and a reduced number of
stars is shown.
To support an efficient driving style, ECO PRO
tips are shown during the journey.
