2014 BMW 640I CONVERTIBLE stop start

of collision, the system can assist with a slight
braking intervention. The intervention can
bring a vehicle traveling at slow speed 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
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle,
switch off the collision warning with braking
function to prevent undesired interventions.
System limits Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring.◀
Detection range
The system's detection capabilities are limited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:▷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.▷Pedestrians.
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, for example, DSC
OFF.▷If the camera in the mirror or the radar sen‐
sor is dirty or obscured.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant dimming because of
oncoming light, for example, from the sun
low in the sky.
Prewarning sensitivity
Depending on the set prewarning time, this
may result in increased false warnings.
Pedestrian warning
Depending on how the vehicle is equipped, the
function warns of an imminent collision with
pedestrians during daytime or nighttime.
The function is subdivided into the following
systems:
▷During daytime: Pedestrian warning with
city braking function, refer to page 110▷At night: Night Vision with pedestrian de‐
tection, refer to page 112
Pedestrian warning with city
braking function
The concept The system can help to prevent accidents with
pedestrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐
lision with pedestrians and includes a braking
function.
The system is controlled via the camera in the
base of the interior mirror.

General information
The system issues a warning with brightness
staring at approx. 6 mph/10 km/h to approx.
35 mph/60 km/h regarding a possible risk of
collision with pedestrians and assists with a
brake intervention shortly before a collision.
It responds to persons that are within the de‐
tection range of the system.
Detection range
The warning area in front of the vehicle is div‐
ided into two areas.
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
A collision is imminent if pedestrians are lo‐
cated within the central area. A warning is is‐
sued about pedestrians who are located within
the extended area only if they are moving in
the direction of the central area.

Braking intervention
The warning prompts the driver himself to in‐
tervene. During the warning, the maximum
braking force is used, even with light pressure
on the brake pedal. In addition, if there is a risk
of collision, the system can assist with a slight
braking intervention. The intervention can
bring a vehicle traveling at slow speed 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
pressing on the accelerator or by actively mov‐
ing the steering wheel.

shield are dirty or covered.▷When driving toward bright lights.▷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.
Night Vision with Pedestrian
and Animal Detection
The concept Night Vision with pedestrian and animal detec‐
tion is a night vision system.
An infrared camera records the area in front of
the vehicle and issues a warning if it detects
pedestrians and animals on the street. Warm
objects that are similar in shape to human be‐
ings or animals are detected by the system. If necessary, the heat image can be displayed on
the Control Display.

Driving stability control systemsVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable 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 maximum braking
force boost. This then reduces braking dis‐ tance to a minimum during full braking. This
system utilizes all of the benefits provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
When equipped with Driving Assistant Plus or
with Active Cruise Control with Stop & Go
function, ACC is supported by the braking in‐
tervention if there is a possible risk of collision.
To do this, the braking force is automatically increased if the braking pressure is insufficient
when the brakes are applied.Adaptive brake assistant
In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.
Drive-off assistant
This system supports driving away on gradi‐
ents. The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes at individual
wheels.

System limits
The cameras capture a maximum range of
330 ft/100 m.
Parking assistantThe concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC and
the parking assistant and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 142.
Hints Personal responsibility
The parking assistant does not relieve
the driver of responsibility for the vehicle dur‐
ing the parking procedure.
Watch the parking space and parking proce‐
dure closely and intervene if necessary; other‐
wise, there is the danger of an 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 danger of an acci‐
dent occurring.◀
Transporting loads
Loads that extend beyond the perimeter
of the vehicle are not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curbs.
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.▷Minimum length of the gap: own vehicle's
length plus approx. 4 ft/1.2 m.▷Minimum depth: approx. 5 ft/1.5 m.
For parking procedure
▷Closed doors.▷Parking brake released.Seite 150ControlsDriving comfort150

On a downhill gradient, take your foot off the
accelerator 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.
Automatic Engine 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.
Using this system can cause certain compo‐
nents of the vehicle to become worn prema‐
turely.
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
consume additional fuel, especially in city and
stop-and-go traffic.
Therefore, switch off these functions if they
are not actually needed.Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
Have the maintenance carried out by your
service center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 208.
ECO PRO
The concept ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort functions, e. g. the
climate control output, are adjusted.
In addition, context-sensitive instructions can
be displayed that assist in driving in a manner
that optimizes fuel consumption.
The extension of the range that is achieved as
a result can be displayed in the instrument
cluster.
