DRIVING TIPS
Saving fuel
Closing the windows
Open windows increase drag and therefore
lead to greater fuel consumption.
Vehicle features and options
This chapter describes all standard, country-
specific, and optional equipment offered with
the series. It also describes features and func-
tions that are not necessarily available in the
vehicle, e.g., due to the selected options or
country versions. This also applies to safety
functions and systems. When using these
functions and systems, the applicable laws
and regulations must be observed.
Tires
General information
Tires can affect consumption in various ways,
for instance tire size may influence consump-
tion.
Checking the tire pressure regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Reducing fuel consumption
General information
The vehicle contains advanced technologies
for the reduction of consumption and emission
values.
Low tire pressure increases rolling resistance
and thus fuel consumption and tire wear.
Observe the correct tire inflation pressure as
well as the ECO tire inflation pressure, where
applicable.
The fuel consumption depends on various fac-
tors such as driving style, road conditions,
maintenance or environmental factors.
Additional information:
Tire pressure specifications, refer to page 310.
Carrying out certain measures such as a mod-
erate driving style and regular maintenance
can influence fuel consumption and the envi-
ronmental pollution.
Drive away without delay
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate RPM.
Removing unnecessary cargo
Additional weight increases fuel consumption.
This is the fastest way of warming the cold
engine up to operating temperature.
Removing attached parts following
use
Remove roof-mounted luggage racks that are
no longer required following use.
Anticipatory driving
A smooth and anticipatory driving style re-
duces fuel consumption.
Avoid unnecessary acceleration and braking.
Attached parts on the vehicle impair the aero-
dynamics and increase the fuel consumption.
Maintain a suitable distance to the vehicle driv-
ing ahead of you.

Saving fuel
DRIVING TIPS
The ECO PRO driving mode supports the en-
ergy conserving use of comfort features.
Avoid high RPM
Driving at low engine speeds lowers fuel con-
sumption and reduces wear.
These functions are automatically deactivated
partially or completely.
If necessary, observe the vehicle's gear shift
indicator.
Having maintenance carried out
Have the vehicle maintained regularly to ach-
ieve optimal vehicle efficiency and service life.
BMW recommends that maintenance work be
performed by an authorized service center.
Using coasting/overrun mode
When approaching a red traffic light, take your
foot off the accelerator and let the vehicle
coast to a halt.
Also refer to BMW Maintenance System.
For going downhill take your foot off the accel-
erator and let the vehicle roll.
The fuel supply is interrupted in coasting/over-
run mode.
ECO PRO
Principle
Switch off the engine during longer
stops
ECO PRO supports a driving style that saves
on consumption. For this purpose, the engine
control and comfort features, for instance the
climate control output, are adjusted.
Switching off the engine
Switch off the engine during longer stops, for
instance at traffic lights, railroad crossings or in
traffic jam.
Steptronic transmission: under certain condi-
tions the engine is automatically decoupled
from the transmission in the D selector lever
position. The vehicle continues traveling in
Neutral to reduce consumption. The D selector
lever position remains engaged.
Auto Start/Stop function
The Auto Start/Stop function of the vehicle au-
tomatically switches off the engine during a
stop.
In addition, situational information and ECO
PRO tips are displayed to help promote a
power-saving driving style.
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 an engine stop.
The achieved extended range is displayed in
the instrument cluster as bonus range.
General information
The system includes the follow-
ing EfficientDynamics functions and
EfficientDynamics displays:
Switching off any functions that are
not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
increase fuel consumption, especially in city
traffic and with stop-and-go driving.

Button
Efficiency can be optimized by disengaging the
engine and coasting in Neutral.
Activating ECO PRO
ECO PRO seat climate control
Press the button. ECO PRO is dis-
played in the instrument cluster.
The activation of ECO PRO will reduce the out-
put of the seat heating.
ECO PRO climate control
The air conditioning is adjusted.
Configuring ECO PRO INDIVIDUAL
Via the Driving Experience Control
1. Activate ECO PRO.
This means it is possible to deviate slightly
from the set temperature and heat or cool the
car interior more slowly to economize on elec-
trical consumption.
2. "ECO PRO INDIVIDUAL"
Via iDrive
1. "CAR"
ECO PRO light and view
The output of exterior mirror heating and rear
window defroster is reduced.

ECO PRO bonus range
A modified driving style helps
you extend your driving range.
The total time that the engine has been
switched off during automatic engine stops.
The range extension can be dis-
played as the bonus range in
the instrument cluster.
A gear shift indicator recommending the
use of a more efficient gear.
The efficiency display includes the bonus
range.
Indications on the control display
If the bonus range appears in gray, the current
driving style is inefficient.
General information
Information about the current operating princi-
ple of the ECO PRO functions can be displayed
as energy flow.
The display turns blue as soon as all condi-
tions for efficient driving are met.
The intervals for resetting the bonus range de-
pend on the settings of the trip data.
Displaying energy flow information

Coasting
A needle in the consumption display informs
about the current driving style:
Principle
▷
The current consumption in relation to the
average consumption is displayed.
Under certain conditions the engine is auto-
matically decoupled from the transmission in
the D selector lever position. The vehicle con-
tinues traveling in Neutral to reduce consump-
tion. Selector lever position D remains en-
gaged.
▷
Needle in the area of arrow 1: display of
the energy recovered by coasting or when
braking.
▷
Needle in the area of arrow 2: display when
accelerating.
This driving condition is referred to as coast-
ing.
If the acceleration is inefficient, the area be-
tween the average consumption and the cur-
rent consumption is colored red.
As soon as the brake or accelerator pedal is
depressed, the engine is automatically coupled
to the transmission again.
In addition, the following information is dis-
played, depending on the situation:

DRIVING TIPS
Driving style analysis
Principle
The function helps develop an especially effi-
cient driving style and to conserve fuel.
For this purpose, the driving style is analyzed.
The assessment is done in various categories
and is displayed on the control display.
This display will help you adjust your driving
style and save some fuel.
General information
The current trip is assessed.
To support an efficient driving style, ECO PRO
tips are displayed while driving.
The range of the vehicle can be extended by
adjusting your driving style.
This gain in range is displayed as a bonus
range in the instrument cluster and on the con-
trol display.
Functional requirement
This function is available in ECO PRO driving
mode.
Calling up the Driving style analysis
1. "CAR"
2. "Driving information"
3. "Driving style analysis"
Display on the control display
The display of the Driving style analysis shows
the efficiency of the Driving style.
The more efficient the driving style, the more
bars are displayed in color and the faster the
bonus range increases.
In contrast, a reduced number of bars will be
displayed with an inefficient driving style.
