2014 BMW 640I CONVERTIBLE steering wheel

The red symbol is displayed and a sig‐
nal sounds.
Intervene immediately by braking or
making an evasive maneuver.
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.
When towing or tow-starting the vehicle,
switch off the pedestrian warning 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 detection capability of the camera is lim‐
ited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.▷Pedestrians below a body size of approx.
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 camera view field or the front wind‐
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.

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. Depending
on the country-specific version of the vehicle,
the speed is between 35 mph/55 km/h and
45 mph/70 km/h. If the system is switched on
below this speed, a message appears in the in‐
strument cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Notes Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the
course of the road and the traffic situation.
In the event of a warning, do not jerk the steer‐
ing wheel, as you may lose control of the vehi‐
cle.◀

Indicator/warning lamps
When DTC is activated, TRACTION is dis‐
played in the tachometer.
The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
xDrive xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
HDC Hill Descent Control
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. walking speed and then keeps its
speed constant.
As long as there is active braking, the system
is on standby. The system does not brake the
vehicle during this time.
Use HDC in low gears or in transmission posi‐
tion D or R only.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker switch of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.▷Press up the rocker switch to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point
of resistance: the speed increases while
the rocker switch is pressed.▷Press down the rocker switch to the point
of resistance: the speed decreases gradu‐
ally.▷Press down the rocker switch past the
point of resistance: when driving forward,
the speed decreases to approx.
6 mph/10 km/h; when reversing, the speed
decreases to approx. 4 mph/6 km/h.

Adaptive Drive
The concept Adaptive Drive includes the following systems:
▷Dynamic Drive, refer to page 125.▷Dynamic Damping Control, refer to
page 125.
The system increases driving stability and driv‐
ing comfort.
Dynamic Drive The conceptDynamic Drive reduces the lateral inclination of
the vehicle that occurs during rapid driving in
curves or during quick evasive maneuvers.
Driving stability and driving comfort are in‐
creased under all driving conditions. The sys‐
tem utilizes active stabilizer bars on the front
and rear axles that react immediately to all driv‐
ing situations.
Programs The system offers two different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 126.
SPORT
Sporty tuning for greater driving agility.
COMFORT
Comfort-oriented tuning for optimal comfort.

Integral Active Steering The conceptIntegral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.Seite 125Driving stability control systemsControls125
Online Edition for Part no. 01 40 2 910 721 - VI/13

At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in
a direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.
The rear wheels are turned to the same angle
as the front wheels.
In critical situations, Integral Active Steering
can specifically steer the front and rear wheels
to stabilize the vehicle before the driver inter‐
venes, e.g., when braking where road condi‐
tions differ on the left and right sides of the ve‐
hicle.
InitializingIn rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.1.With the engine running, turn the steering
wheel all the way to the left and right sev‐
eral times in a uniform manner until the
warning lamp disappears.2.Have the system checked if the warning
lamp does not go out after moving the
steering wheel approx. 6 times or if the
steering wheel is at an angle.
Using snow chains
Note When snow chains are in use, refer to
page 202, rear wheel steering is deactivated.
Programs The system offers several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 126.
SPORT
Consistently sporty tuning of the Integral Ac‐
tive Steering for greater driving agility.
COMFORT
Balanced tuning of the Integral Active Steering
for optimal traveling comfort.
Malfunction
In the event of a malfunction, the steering
wheel must be turned further, while the vehicle
responds more sensitively to steering wheel
movements in the higher speed range.
The stability-enhancing intervention may be
deactivated.
Proceed cautiously and drive defensively.
Have the system checked.
Driving Dynamics Control The conceptThe Driving Dynamics Control can be used to
adjust the driving dynamics of the vehicle. For
this purpose various programs are available for
selection that are activated via the two buttons
of the Driving Dynamics Control and the DSC
OFF-button.

Driving comfortVehicle equipment
All 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.
Active Cruise Control with Stop & Go function, ACC
The conceptThis system can be used to select a desired
speed that the vehicle will maintain automati‐
cally 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 decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
If the vehicle ahead of you brakes to a halt, the
system is able to detect this within the given
system limits. If the vehicle ahead of your
drives away again from a halt, your vehicle is
able to accelerate if operated accordingly.
Even if some time passes before the vehicle
drives away again, the BMW can still be accel‐
erated automatically and simply.
As soon as the road is clear, it accelerates to
the desired speed.
The speed is also maintained on downhill gra‐
dients, but may not be maintained on uphill
slopes if engine power is insufficient.General information
When ECO PRO is activated, cruise control is
also set to a driving style that saves on fuel
consumption.
Notes Personal responsibility
The system does not relieve the driver of
the responsibility to adapt his or her speed,
distance and driving style to the traffic condi‐
tions. Drive attentively, and react to the current
traffic events. Intervene actively when neces‐
sary, e.g., by braking, steering or making an
evasive maneuver, otherwise, there is danger
of an accident.◀
