warning BMW 640I CONVERTIBLE 2012 Owner's Manual

Warning
If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the mirror housing flashes
brightly.
The warning stops when the turn signal is
switched
off, or the other vehicle leaves the crit‐
ical zone.
System limits
Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the traffic
situation.
In the event of a warning, do not jerk the steering
wheel, as you may lose control over the vehi‐
cle.◀
The system may not be fully functional in the
following situations:
▷ When a vehicle is approaching at a speed
much faster than your own.
▷ In heavy fog, rain or snowfall.
▷ In tight curves or on narrow lanes.

Driving stability control systems
Antilock Brake System ABS
ABS
prevents locking of the wheels during brak‐
ing.
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. It thus helps to achieve the shortest
possible braking distance 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.
Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.
1. Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive away with‐
out 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 driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 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. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes at individual wheels.
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The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps
The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
DTC Dynamic Traction
Control
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der the following special circumstances: Seite 101

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 intervenes,
e.g., when braking where road conditions differ
on the left and right sides of the vehicle.
Initializing
In 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 several
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 steer‐
ing wheel approx. 6 times or if the steering
wheel is at an angle.
Using snow chains
Ensure
that the rear axle steering is deactivated
when using snow chains, refer to page 235.

Malfunction
In the event of a malfunction, the steering wheel
must be turned further, while the vehicle re‐
sponds more sensitively to steering wheel
movements in the higher speed range. The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked.
Dynamic Driving Control*
The concept
Dynamic Driving Control can be used to adjust
the

driving dynamics of the vehicle. Several pro‐
grams are available for this purpose; they can be
activated using the two Dynamic Driving Control

Measurement
Measurements
are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷ By the front* sensors and the two rear cor‐
ner sensors at approx. 24 in/60 cm.
▷ By the rear middle sensors at approx. 5 ft/
1.50 m.
System limits Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion.

Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, for instance:
▷ With tow bars and trailer hitches.
▷ With thin or wedge-shaped objects.
▷ With low objects.
▷ With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move
into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected. False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷
In heavy rain.
▷ When sensors are very dirty or covered in
ice.
▷ When sensors are covered in snow.
▷ On rough road surfaces.
▷ In large buildings with right angles and
smooth

walls, e.g., in underground garages.
▷ In heavy exhaust.
▷ Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.

Signal tones
When approaching an object, an intermittent
tone
is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 12 in/30 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:
▷ If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.
▷ If moving parallel to a wall.
The signal tone is switched off:
▷ When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.
▷ When transmission position P is engaged.
Volume
You can set the volume of the PDC signal tone,
refer to page 165.
The

setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal tone sounds.

Pedestrian detection
The pedestrian detection and warning system
only
operates in darkness and only when a heat
image is displayed.
Warm objects that are similar in shape to human
beings are detected by the system.
People detected by the system are displayed
with a slight yellow hue.
Under good ambient conditions, the pedestrian
detection system operates within a range of ap‐
prox. 50 ft/15 m to approx. 330 ft/100 m. Environmental influences can limit the availabil‐
ity of pedestrian detection.
If

pedestrian detection is not available, a symbol
is displayed in the heat image.
This symbol disappears when the function be‐
comes available again. Warning of people in danger If the system detects a person in the defined
area

in front of the vehicle and if there is the dan‐
ger of a collision with this person, a warning
symbol appears in the Control Display and
Head-up Display*.
Although both the shape and the heat radiation
are analyzed, false warnings cannot be ruled out.
Warning area in front of the vehicle The warning area in front of the vehicle is divided
into two areas.
▷
Central area 1 directly in front of the vehicle.
▷ Expanded area 2 to the right and left.
The entire area moves along with the vehicle in
the direction of the steering angle and changes
with

the vehicle speed. As the vehicle speed in‐
creases, the area becomes longer and wider, for
example.
