2013 BMW 740LI sensor

Collision warning with
braking function
The concept
The system issues a warning if there is imminent
danger of a collision and also includes a braking
function.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the collision warning is
controlled via the cruise control radar sensor in
conjunction with a camera.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought into
contact with a vehicle, the collision warning is
delayed to avoid false warnings.
Detection range
Detection range
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
General information
The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h. The time of these warnings
may vary depending on the current driving sit‐
uation.

Adapting your speed and driving style
The display does not relieve the driver of
the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
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 danger of an
accident occurring.◀
Detection range
The detection capacity of the radar sensor and
the collision warning has limitations.
This may result in the warning not being issued
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 snowfall.▷In tight curves.▷If the radar sensor is dirty or obscured.
Prewarning sensitivity
Depending on the set prewarning time, this may
result in increased false warnings.
Night Vision with pedestrian
detection
The concept
Night Vision with pedestrian detection is a night
vision system.
An infrared camera records the area in front of
the vehicle and issues a warning if it detects pe‐
destrians on the street. Warm objects that are
similar in shape to human beings are detected
by the system. If necessary, the heat image can
be displayed on the Control Display.
Depending on how the vehicle is equipped, peo‐
ple will be illuminated by a Light Spot or Dynamic
Light Spot so that they are more easibly visible.
Heat image
The image shows the heat radiated by objects
in the field of view of the camera.
Warm objects have a light appearance and cold
objects, a dark appearance.
The ability to detect an object depends on the
temperature difference between the object and
the background and on the level of heat radiation
emitted by the object. Objects that are similar in
temperature to the environment or that radiate
very little heat are difficult to detect.
For safety reasons, when driving at speeds
above approx. 3 mph/5 km/h and in low ambient
light, the image is only displayed when the low
beams are switched on.
A still image is displayed at regular intervals for
a fraction of a second.

▷In heavy fog, rain or snowfall.▷In the event of worn, poorly visible, merging,
diverging, or multiple lane markings such as
in construction areas.▷When lane markings are covered in snow,
ice, dirt or water.▷In tight curves or on narrow lanes.▷When the lane markings are covered by ob‐
jects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield behind the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.▷During calibration of the camera immedi‐
ately after vehicle shipment.
Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper mon‐
itor the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehicles
in the blind spot, arrow 1, or approaching from
behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing lights up
dimly.
Before you change lanes after setting the turn
signal, the system issues a warning in the situa‐
tions described above.
The lamp in the housing of the exterior mirror
flashes and the steering wheel vibrates.

Driving comfortVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Active Cruise Control with
Stop & Go function, ACC
The concept
This 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 automatically
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
Active Cruise Control calculates the vehicle's
speed and distance from other vehicles with the
aid of a radar sensor and a camera.
When ECO PRO is activated, cruise control is
also set to a driving style that saves on fuel con‐
sumption.
Notes Personal responsibility
The system does not relieve the driver of
the responsibility to adapt his or her speed, dis‐
tance and driving style to the traffic conditions.
You should drive attentively and intervene ac‐
tively when necessary, e.g. by braking or making
an evasive maneuver, otherwise, there is danger
of an accident.◀

PDC Park Distance Control
The concept
PDC supports you when parking. Objects that
you are approaching slowly in front of or behind
your vehicle are indicated by:▷Signal tones.▷Visual display.
General information
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 corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
Notes
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.◀
