2014 BMW 740LI sensor

Therefore, drive into a curve at an appropriate
speed.
In tight curves, situations may result due to the
restricted detection range of the system in
which a vehicle driving ahead of you may not
be detected at all, or not until after a consider‐
able delay.
When approaching a curve, the system may
react briefly to the vehicles in the next lane due
to the bend of the curve. Any deceleration of
the vehicle by the system can be compensated
for by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Driving away In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines or
behind bumps in the road.
Radar sensor
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:
FCC ID:
▷OAYARS3-A
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking, for
example.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situation:
▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Congestion Assistant
The concept In congestion situations, the system controls
the speed, steers independently and keeps the
vehicle in the lane.
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 sys‐
tem automatically decelerates, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
When lane markings are detected, the system
keeps the vehicle in the lane. For this purpose,
the system steers independently as needed,
for example, during cornering.

General information
The congestion assistant determines speed
and distance from the vehicle in front via a ra‐
dar sensor and the position of the lane marking
via a camera.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
The system is deactivated as soon as contact
with the steering wheel is no longer detected.
In order to be able to use the Congestion As‐
sistant, place your hands around the steering
wheel.
When driving with gloves or with protective
covers, contact with the steering wheel cannot
be detected by the sensors. The system in this
case cannot be used.
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.◀

System limits
When driving within narrow driving lanes, e.g.,
in construction zones or rescue lanes, the sys‐
tem cannot be activated or meaningfully used.
Limited detection capacity
Because of the limits to the detection ca‐
pacity of the camera and the sensor, you
should be alert at all times so that you can in‐
tervene actively, if necessary; otherwise, there
is the danger of an accident occurring.◀
Complying with country-specific laws
When the Congestion Assistant is used,
observe specific national laws.◀
Cruise control
The concept The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:

PDC Park Distance ControlThe concept
PDC supports you when parking. Objects that
you are approaching slowly in front of or be‐
hind your vehicle are indicated by:▷Signal tones.▷Visual display.
General information
Measurements are made by ultrasound sen‐
sors 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.
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 ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehi‐ cle 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.

Display
Signal tones When approaching an object, an intermittent
tone is sounded that indicates the position of
the object. For example, if an object is de‐
tected to the left rear of the vehicle, a signal
tone sounds from the left rear speaker.
The shorter the distance to the object be‐
comes, the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
If objects are located both in front of and be‐
hind the vehicle, an alternating continuous sig‐
nal is sounded.
The intermittent tone is interrupted after ap‐
prox. 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
The volume of the PDC signal can be adjusted,
refer to user's manual for Navigation, Enter‐
tainment, Communication.
The setting is stored for the remote control
currently 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
Display before a signal tone sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in the
colors red, green and yellow.
If the rearview camera image was selected last,
it again appears on the display. To switch to
PDC:1. "Rear view camera" Select the symbol
on the Control Display.2.Press the controller.
The setting is stored for the remote control

System limits
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, e.g.:
▷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 ga‐
rages.▷In heavy exhaust.Seite 146ControlsDriving comfort146

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 145.
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.
