2012 BMW 335I tow

▷Off: the LED goes out.
The state is stored for the remote control cur‐
rently in use.
Configuring the warning time
After the warning function is switched on, the
warning time can be set via the iDrive. For a late
warning time, prewarning is deactivated.
These settings have no effect on the time of the
warning from the Active Cruise Control that
prompts the driver to intervene or brake.
Display in the instrument cluster
The collision warning can be issued in the in‐
strument cluster, in the Head-up Display, and
acoustically.
Warning stages
SymbolMeasureThe vehicle lights up red: prewarn‐
ing.
Increase distance.The vehicle flashes red and an
acoustic signal sounds: acute warn‐
ing.
You are requested to intervene by
braking or making an evasive maneu‐
ver.
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 camera 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.
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 camera view field or the front wind‐
shield are dirty or covered.▷When driving toward bright lights.▷In the case of vehicles with insufficiently visi‐
ble tail lamps.▷In the case of partially covered vehicles.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During the calibration process of the camera
immediately after vehicle shipment.
Prewarning sensitivity
Depending on the set prewarning time, this may
result in increased false warnings.

Camera
The camera is located near the base of the mir‐
ror.
Keep windshield clean and clear in the area in
front of the interior rear view mirror.
Collision warning with
braking function
The concept
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the collision warning is
controlled via the cruise control radar sensor.
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.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
When the vehicle is intentionally brought into
contact with a vehicle, the collision warning is
delayed to avoid false warnings.
Warning stages
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
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 collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.Seite 117Driving comfortControls117

If --- appears briefly on the display for Check
Control messages, it is possible that the system
requirements for operation are currently not
met.
PDC Park Distance Control
The concept
In addition to the PDC Park Distance Control, the
backup camera, refer to page 123, can be
switched on.
PDC supports you when parking. Objects that
you are approaching slowly in front of or behind
your vehicle are indicated with:▷Signal tones.▷Visual display.
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 two rear corner
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, 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 garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due to
other ultrasound sources is no longer
present, the system is again fully functional.Seite 121Driving comfortControls121

▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With elevated, protruding objects such as
ledges or cargo.▷With objects with corners and sharp edges.▷With objects with a fine surface structure,
such as fences.
The parking assistant may identify parking
spaces that are not suitable for parking.
Ultrasound sensors
The ultrasound sensors for measuring parking
spaces are located on the wheel arches.
To ensure full operability:
▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and main‐
tain a distance of at least 12 in/30 cm.Seite 133Driving comfortControls133
