If the vehicle is not maintained according to
these specifications, this could result in seri‐
ous damage to the vehicle. Such damage is
not covered by the BMW New Vehicle Limited
Warranty.
Data memory
Many electronic components on your vehicle
are equipped with data memories that tempo‐
rarily or permanently store technical informa‐
tion about the condition of the vehicle, events
and faults. This technical information generally
records the state of a component, a module, a system or the environment:
▷Operating mode of system components, fill
levels for instance.▷Status messages for the vehicle and from
its individual components, e.g., wheel rota‐
tion speed/vehicle speed, deceleration,
transverse acceleration.▷Malfunctions and faults in important sys‐
tem components, e.g., lights and brakes.▷Responses by the vehicle to special situa‐
tions such as airbag deployment or engag‐
ing the stability control system.▷Ambient conditions, such as temperature.
This data is purely technical in nature and is
used to detect and correct faults and to opti‐
mize vehicle functions. Motion profiles over
routes traveled cannot be created from this
data. When service offerings are used, e.g., re‐
pair services, service processes, warranty
claims, quality assurance, this technical infor‐
mation can be read out from the event and
fault memories by the service personnel, in‐
cluding the manufacturer, using special diag‐
nostic tools. You can obtain further information
there if you need it. After an error is corrected,
the information in the fault memory is deleted
or overwritten on a continuous basis.
With the vehicle in use there are situations
where you can associate these technical data
with individuals if combined with other infor‐
mation, e.g., an accident report, damage to the
vehicle, eye witness accounts — possibly with
the assistance of an expert.
Additional functions that are contractually
agreed with the customer - such as vehicle
emergency locating - you can transmit certain
vehicle data from the vehicle.
Event Data Recorder EDR
This vehicle is equipped with an event data re‐
corder EDR. The main purpose of an EDR is to
record, in certain crash or near crash-like situa‐
tions, such as an air bag deployment or hitting
a road obstacle, data that will assist in under‐
standing how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a
short period of time, typically 30 seconds or
less.
The EDR in this vehicle is designed to record
such data as:▷How various systems in your vehicle were
operating.▷Whether or not the driver and passenger
safety belts were fastened.▷How far, if at all, the driver was depressing
the accelerator and/or brake pedal.▷How fast the vehicle was traveling.
These data can help provide a better under‐
standing of the circumstances in which
crashes and injuries occur.
EDR data are recorded by your vehicle only if a
nontrivial crash situation occurs; no data are
recorded by the EDR under normal driving
conditions and no personal data, e.g., name,
gender, age, and crash location, are recorded.

Driving with combustion engine:
DRIVE
The combustion engine, refer to page 72,
provides the primary performance to move the
vehicle. If necessary, the high-voltage battery is charged at the same time.
The hybrid system always starts the combus‐
tion engine automatically.
Energy recovery: CHARGE The high-voltage battery of the hybrid system
is charged through energy recovery while driv‐
ing.
The electric motor acts as a generator and
converts the kinetic energy of the vehicle into
electric current.
Charging can take place in various situations:▷When the vehicle is coasting if the acceler‐
ator pedal is not pressed.▷During vehicle braking.
When exerting gentle pressure on the brakes,
the vehicle is only braked by the electric motor.
When the brake pedal is depressed further, the
brake system is activated additionally. This is
why only part of the brake energy is used to
charge the high-voltage battery when exerting
firm pressure on the brake.
Foresighted driving and the early reduction of
speed are important to make full use of the hy‐
brid characteristics of the vehicle.
Coasting The engine is automatically switched off. This
driving condition of rolling is referred to as
coasting, refer to page 71.
Auxiliary functions of the automatic
climate control
The hybrid system makes it possible to oper‐
ate the automatic climate control prior to driv‐
ing off and with the combustion engine
switched off.
Using the auxiliary air conditioning and residual
cooling functions, the vehicle interior can be
cooled immediately prior to departure and if
the trip is interrupted.▷Residual cooling, refer to page 155.▷Auxiliary air conditioning, refer to
page 155
Adapting to the course of the road
When the navigation system destination guid‐
ance is active, the hybrid system uses the ex‐
isting navigation data. Hybrid operation adapts
to the specific route sections. These may be:
▷Steep gradients.▷Arrival in the destination zone.
Pay attention to the notes in Adapting to the
course of the road, refer to page 84.
Display
The displays of the hybrid system, refer to
page 82, provide information about the cur‐
rent state of hybrid operation and show the
system activity in a chart.
Energy-saving driving To save energy while driving, read the follow‐
ing information:
▷Saving fuel, refer to page 180.▷Using the hybrid system efficiently, refer to
page 172▷ECO PRO mode, refer to page 181.▷Adapting to the course of the road, refer to
page 84.
Safety information
Read the information on safe handling of the
high-voltage system, refer to page 34.
Long-term
Follow the instructions for vehicle storage and
for longer idle periods, refer to page 231

Front-end collision warning
Depending on the equipment, the collision
warning system consists of one of the two sys‐
tems:▷Front-end collision warning with City Brak‐
ing function, refer to page 113.▷Front-end collision warning with braking
function, refer to page 115
Front-end collision warning
with City Braking function
The concept The ystem can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention is done
with limited force and duration.
A camera in the area of the rearview mirror
controls the system.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally the collision warning is delayed
avoiding false alarm.
General information
The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.
Detection range
It responds to objects if they are detected by
the system.
Hints Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀
Adapting your speed and driving style
The displays and warnings of the system
do not relieve the driver of the responsibility to
adapt his or her driving speed and style to the
traffic conditions.◀
Be alert
Due to system limitations, warnings may
be not issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the risk
of an accident.◀

Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous prewarning.
Braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with
some braking intervention if there is risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Detection range
The system's detection potential is limited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
limited or deactivated, e.g., DSC OFF.▷If, depending on the vehicle equipment
version, the field of view of the camera in
the mirror or the radar sensor is dirty or ob‐
scured.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
e.g. the warning time, the more warnings are
displayed. However, there may also be an ex‐
cess of false warnings.
Front-end collision warning
with braking function
The concept The ystem can help prevent accidents. If an
accident cannot be prevented, the system will help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.

Driving stability control systemsVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving with
roof load
Do not deactivate Dynamic Stability Control DSC when driving with roof load, e.g. roof-
mounted luggage rack.
Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀

Driving comfortVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Active Cruise Control with Stop & Go function, ACC
The concept
Use this system to select a desired speed that
the vehicle will maintain automatically on clear
roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically reduces the speed, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pe‐
riod, the system is able to detect this within the
given system limits. Your own vehicle will
brake automatically and then accelerate again.
If the vehicle ahead of you drives away again
after a prolonged period, briefly press the ac‐
celerator pedal or press the appropriate button
to reactivate the system. The vehicle will auto‐
matically accelerate.As soon as the road is clear, the vehicle accel‐
erates to the desired speed.
The speed is also maintained downhill, but
may not be maintained uphill if engine power is
insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Personal responsibility
Even an active system holds the driver
responsible for his or her driving, particularly
for staying in your lane, adjusting your speed,
keeping your distance and for your driving
style all in relation to traffic.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed, e.g. through braking,
steering or make evasive maneuvers - risk of
accident.◀
Unfavorable weather conditions
In the event of unfavorable weather and
light conditions, e. g. if there is rain, snowfall,
slush, fog or glare, this may result in poorer
recognition of vehicles as well as short-term
interruptions for vehicles that are already de‐
tected. Drive attentively, and react to the cur‐
rent traffic situation. Intervene actively when
necessary, e.g., by braking, steering or making
an evasive maneuver, otherwise, there is the
risk of an accident.◀Seite 130ControlsDriving comfort130

Before leaving the vehicle, secure it
against moving on its own.
Before leaving the vehicle with the engine run‐
ning: set the parking brake and ensure that the
Steptronic transmission is in position P. Other‐
wise, the vehicle may begin to move.◀
