Warning with braking function
Display
If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
The red symbol is displayed and a sig‐
nal sounds.
Intervene immediately by braking or make an
evasive maneuver.
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 detection potential of the camera is lim‐
ited.Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.▷Pedestrians having a body size less than
32 in/80 cm.
Functional limitations
The system may not be fully functional or may
not be available in the following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷If the camera viewing field or the front
windshield are dirty or covered.▷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.▷When it is dark outside.
Lane departure warning
The concept Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. This
speed, depending on the country version, is
between 35 mph/55 km/h and
45 mph/70 km/h.

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.◀

HintsPersonal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
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 - risk of accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements
For measuring parking spaces▷Maximum speed while driving forward ap‐
prox. 22 mph/35 km/h.▷Maximum distance to row of parked vehi‐
cles: 5 ft/1.5 m.
Suitable parking space
▷Gap between two objects with a minimum
length of approx. 5 ft/1.5 m.▷Min. length of gap between two objects:
your vehicle's length plus approx.
4 ft/1.2 m.▷Minimum depth: approx. 5 ft/1.5 m.
Regarding the parking procedure
▷Doors and trunk lid closed.▷Parking brake released.▷When parking in parking spaces on the
driver's side, the corresponding turn signal
must be set where applicable.

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

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.

▷Do not rub dry and do not use abrasive or
acidic cleansers.▷Soak areas that have been dirtied e. g.,
from insects, with shampoo and wash off
with water.▷Thaw ice with de-icing spray; do not use an
ice scraper.
Lowerable hardtop
When the wet hardtop is opened, water drop‐
lets can run into the trunk. Remove any objects
in the trunk beforehand to prevent water spot‐
ting or soiling.
After washing the vehicle
After washing the vehicle, apply the brakes
briefly to dry them; otherwise, braking action
can be reduced and corrosion of the brake
discs can occur.
Completely remove all residues on the win‐
dows, to minimize loss of visibility due to
smearing and to reduce wiper noises and
wiper blade wear.
Vehicle care
Car care products BMW recommends using care and cleaning
products from BMW, since these have been
tested and approved.
Car care and cleaning products
Follow the instructions on the container.
When cleaning the interior, open the doors or
windows.
Only use products intended for cleaning vehi‐
cles.
Cleansers can contain substances that are
dangerous and harmful to your health.◀
Vehicle paint
Regular care contributes to driving safety and
value retention. Environmental influences in
areas with elevated air pollution or natural con‐
taminants, such as tree resin or pollen can af‐
fect the vehicle's paintwork. Tailor the fre‐
quency and extent of your car care to these
influences.
Aggressive substances such as spilled fuel, oil,
grease or bird droppings, must be removed im‐
mediately to prevent the finish from being al‐
tered or discolored.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.Seite 222MobilityCare222
