Following Distance Alerts (FDA)
Following Distance Alerts (FDAs) are
enabled above the minimum speed
threshold and are independent of
Active Cruise with Braking (ACB).
FDAs are both audible and visual
indications to you, the driver, whenever
your vehicle is within the alert range of
the detected forward vehicle.
Once the audible alert is given, you
should increase the distance between
your vehicle and the forward vehicle Figure 16 - FDA
until the audible alert stops.
The FDA is ready to alert you even
when your truck is moving at low
speeds. If the distance continues
to decrease, you may hear and see
more rapid alerts. Figure 16 shows
messages you may receive on the
integrated display when the FDA is
activated.
When the FDA reaches its highest
level, the beeping may be rapid and the Figure 17 - Highest Level FDA and IA
Alerts
display may show an additional visual
alert. Figure 17 shows messages you
may see on the integrated display when the highest level FDA and Impact Alert
(IA), or AEB alert, is activated.
NOTE: You, the driver, should intervene to slow down, increase your following
distance with the forward vehicle, or take other action as needed to address
the potential collision.
NOTE: At all times, you, the driver, are responsible for the control and safe
operation of the vehicle and you should be alert and ready to intervene. Never
wait for the system to intervene.
NOTE: The Bendix Fusion system does not react (alert and/or brake) to all potential
collision situations. The system also does not react to stationary objects. As the
driver, you are responsible for the safe operation of the vehicle at all times. For more
information on system limitations, refer to BW8107, Challenging Scenarios, on
B2Bendix.com or the section “Challenging Scenarios and System Limitations”

Impact Alert (IA) and Autonomous Emergency Braking (AEB)
Impact Alert (IA) is the most severe warning the Bendix® Fusion™ system can
make. It can become active starting at low vehicle speeds, but can also change
with different versions of Fusion. Contact your dealer for more information.
The alert indicates that a collision with the detected forward vehicle is likely,
and you should take immediate action to potentially help mitigate a collision.
If you, the driver, do not address the potential forward collision, the Autonomous
Emergency Braking (AEB) function may reduce throttle and automatically apply
up to full service brakes on the tractor while pulsing air to the trailer brakes to
potentially help mitigate a collision.
NOTE: As the driver, your actions can override any Fusion system actions. Once
an AEB event has started, you, the driver, can override its activation by applying
a significant change in accelerator or steering position during the initial stage of
braking or by making a full throttle application. The system may respond with
a warning and some braking before
AEB is suppressed.
If, as a result of the Fusion system
intervention, the vehicle comes to a
full stop, the service brakes may hold
the vehicle at a stop until you, the
driver, intervene.
NOTE: You, the driver, can intervene
by pressing the accelerator or brake
pedal, or applying the parking brake.

Close-Range Braking
If the Bendix® Fusion™ system detects
that your vehicle is closing in on a
detected forward vehicle at a short
distance, the system has the ability
to automatically activate the engine
retarder and apply the service brakes
– if needed – in order to maintain
the distance between you and the Figure 19 – Possible AEB Applied
detected forward vehicle. Figure 19
shows an example of the message you may see on the integrated display.
Please verify with the vehicle OEM for the actual audible and visual indications
your vehicle may display.
NOTE: At all times, you, the driver, are responsible for the control and safe
operation of the vehicle and you should be alert and ready to potentially
intervene. Never wait for the system to intervene.
Pedestrian Autonomous Emergency Braking (PAEB)
At low vehicle speeds, the Bendix® Fusion™ system may react to a detected
pedestrian in the vehicle path and may provide an audible and visual alert from
the OEM integrated display. In most applications, the Pedestrian Autonomous
Emergency Braking (PAEB) feature is enabled at low vehicle speeds. The alert
indicates that a collision with the pedestrian may be likely, and you should take
immediate action to potentially help mitigate a collision.
If you, the driver, do not address the potential forward collision, the Fusion
system may automatically apply up to full service brakes on the tractor while
pulsing air to the trailer brakes – if needed – to potentially help mitigate a
collision.
Figure 19 shows an example of the message you may see on the integrated
display when the PAEB feature is activated. Please verify with the vehicle OEM
for the actual audible and visual indications your vehicle may display.
If, as a result of the PAEB feature intervention, the vehicle comes to a full stop,
the service brakes may hold the vehicle at a stop until you, the driver, intervene.
Service Brake Hold is only available on vehicles equipped with ACB Stop and
Auto-Go™ and ACB Stop and Driver-Go™. Service Brake Hold is not a parking
brake and you must intervene. You, the driver, should manually set the parking
brakes when exiting the vehicle.
NOTE: You, the driver, can intervene by pressing the accelerator or brake pedal,
or applying the parking brake.

•

The vehicle is in reverse gear.

•

The Bendix® ESP®/ABS system in vehicle/trailer is not fully operational.

•

There is an active fault in the radar or camera, or the Bendix ESP system.
Stationary Vehicle Braking (SVB)

When a potential collision with a stationary vehicle in your lane of travel is
detected, the system may sound an alert before braking. If you, the driver,
don’t take action to address the potential impact, the Bendix® Fusion™ system
may reduce throttle and apply the service brakes to potentially help mitigate a
collision with the detected stationary vehicle. If, as a result of the Fusion system
intervention, the vehicle comes to a full stop, the service brakes may hold the
vehicle at a stop until you, the driver, intervene.
NOTE: The Service Brake Hold can be canceled if you, the driver, press the
accelerator pedal or the brake pedal, or apply the parking brake.
Service Brake Hold is only available on vehicles equipped with ACB Stop and
Auto-Go™ and ACB Stop and Driver-Go™.

Lane Departure Warning (LDW)
The Bendix ® Fusion™ system has the ability to warn you if your vehicle
unintentionally departs its lane or you change lanes without using the turn
signal by emitting an audible rumble strip sound to get your attention. In most
applications, the Lane Departure Warning (LDW) feature is enabled above 37
mph (60 kph). If you use the turn signal to change lanes, the LDW feature is
suppressed and no audible or visual alerts are activated. You should always
be aware of your vehicle’s lane position and be ready to immediately correct
as needed.
Figure 21 shows integrated display messages you may see from the LDW
feature. This includes:
A. Driver Assistance Screen. The system is detecting the lane lines.

Overspeed Alert and Action (OAA)
The Bendix ® Fusion™ system can
read most – but not all – roadside
automobile and truck speed limit signs
in the United States and Canada. Sign
detection is enabled for all vehicle
speeds from near 0 mph to maximum
design speed. If more than one sign
is visible, the system may choose the
lowest posted speed limit value.
The Overspeed Alert and Action Figure 27 – OAA
(OA A) may potentially sound an
audible and visual alert when your
vehicle is traveling greater than 5 mph (8 kph) over the posted speed limit.
If your vehicle is traveling at +10 mph (16 kph) over the posted speed limit, in
addition to the alert, you may potentially experience a haptic warning through
a brief engine torque reduction of about one (1) second.
Both the +5 mph (8 kph) and +10 mph (16 kph) thresholds are customizable by
