2016 BMW X4 sensor

Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
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 situations:▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.

played in the Head-up Display.
PDC Park Distance Control
The concept PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is availa‐
ble - then the object is reported through:▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on the ob‐
stacle and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given with the fol‐
lowing circumstances:
▷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.▷When a collision is imminent.
Information
WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
WARNING
Due to high speeds when PDC is acti‐
vated, the warning can be delayed due to
physical circumstances. There is risk of injuries
or risk of property damage. Avoid approaching
an object too fast. Avoid driving off fast while
PDC is not yet active.◀

Switching on/off
Switching on automatically PDC switches on automatically in the following
situations:▷If selector lever position R is engaged
when the engine is running.
The rearview camera also switches on.▷If equipped with front PDC: when obsta‐
cles are detected behind or in front of the
vehicle by PDC and the speed is slower
than approx. 2.5 mph/4 km/h.
You may turn off automatic activation:

manually
Press button.
▷On: the LED lights up.▷Off: the LED goes out.
The rearview camera image is displayed when
the reverse gear is engaged by pressing the
button.
Display
Signal tones When approaching an object, an intermittent
sound indicates the position of the object. E. g.
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, the
shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
Volume
The ratio of the PDC signal tone volume to the
entertainment volume can be adjusted.1."Multimedia", "Radio" or "Settings"2."Tone"3."Volume settings"4."PDC"5.Turn the controller until the desired setting
is selected.6.Press the controller.

used.
Visual warning
The approach of the vehicle to an object can
be shown on the Control Display. Objects that
are farther away are already displayed on the
Control Display before a signal sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in the
colors green, yellow and red.

required when parking and maneuvering on
level roads.
Pathway lines depend on the current steering
angle and are continuously adjusted to the
steering wheel movements.
Turning circle lines
Turning circle lines can only be superimposed
on the rearview camera image together with
pathway lines.
Turning circle lines show the course of the
smallest possible turning radius on a level
road.
Only one turning radius line is displayed after
the steering wheel is turned past a certain an‐
gle.
Obstacle marking
Obstacles behind the vehicle are detected by
the PDC sensors and, when respectively
equipped, detected by the rearview camera.
Obstacle markings can be faded into the image
of the rearview camera.
Their colored margins of the obstacle mark‐
ings match the markings of the PDC.

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 and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 142.
