THE BENDIX® ESP® STABILITY SYSTEM

All vehicles equipped with the Bendix® Fusion™ system are also equipped with the
Bendix® Electronic Stability Program (ESP®) full-stability system. When necessary,
the Bendix ESP system may automatically reduce the accelerator pedal input and/
or apply the service brakes to help you maintain stability during potential loss-ofcontrol or rollover events.
The Fusion system uses the ESP system to help maintain vehicle stability during
service brake applications. The stability icon will be visible on the dash when the
ESP system activates.
The Bendix ESP stability system and the Fusion system do not replace the need
for you to remain alert, react appropriately and in a timely manner, and use safe
driving practices. Bendix safety technologies complement safe driving practices.
Responsibility for the safe operation of the vehicle remains with you, the driver, at
all times.

Improper use of the Bendix ESP and Bendix Fusion system can result in a
collision causing property damage, serious injuries, or death. Be sure to read,
understand, and follow all these instructions carefully.

Bendix safety technologies complement safe driving practices. No commercial
vehicle safety technology replaces a skilled, alert driver exercising safe driving
techniques and proactive, comprehensive driver training. Responsibility for the
safe operation of the vehicle remains with the driver at all times.

IMPORTANT FEATURE INFORMATION
New Functionalities Added: This version of the Bendix® Fusion™ system includes
three (3) new functionalities: Pedestrian Autonomous Emergency Braking (PAEB),
Pedestrian Go/No Go, and High Beam Assist (HBA). This Operator’s Manual informs
you how these features work. Since this version of the Bendix Fusion system uses
a new camera, differences in traditional features like Autonomous Emergency
Braking (AEB), Lane Departure Warning (LDW), Overspeed Alert and Action (OAA),
and Highway Departure Warning/Braking (HDW/HDB) exist and may or may not be
noticed by the driver.

IMPORTANT SAFETY INFORMATION
As a driver, you are always responsible for the control and safe operation of the
vehicle at all times. The Bendix® Fusion™ system does not replace the need for a
skilled, alert professional driver, reacting appropriately and in a timely manner,
and using safe driving practices.
If you determine that a hazard or unsafe condition exists, you should take all
necessary actions immediately. Never wait for the Fusion system to intervene.
Due to the inherent limitations of image recognition technology, camera-based
safety technology may not be able to detect or may misinterpret lane markings,
vehicles, or other objects and may have limited visibility at night. At these times,
alerts may not occur, or erroneous alerts may occur.
The Fusion system may react ONLY to vehicles that the system determines are
stationary or moving in the same direction as your vehicle. The system DOES
NOT respond to side-to-side moving traffic, or oncoming traffic. The system
will not slow your vehicle or provide an alert as you approach vehicles in these
circumstances. See Figure 2.

Detected forward vehicle

Vehicle equipped with the
Bendix® Fusion™ system

The system does not brake nor warn
for vehicles approaching from
the side or oncoming vehicles
in other lanes

Figure 2 – Oncoming or Side-approaching Vehicles
When the Fusion system needs to intervene, it works in conjunction with the
Bendix® Electronic Stability Program (ESP®) full-stability system to activate the
service brakes. The system should never be relied upon to stop your vehicle or
to avoid a collision. You can, and should, still apply full service braking force, if
needed.
The ESP system is specifically calibrated and validated only for your vehicle’s
original configuration. If the vehicle’s chassis components are altered (for
example, a wheel base extension or reduction; tag axle addition or removal;
a major body change such as conversion of a tractor into a truck; or an axle,
suspension, or steering system component modification), the ESP Electronic
Control Unit (ECU) must be updated to reflect these changes. Contact your OEM
prior to making any modifications to your vehicle.
If you modify your vehicle and do not update the ESP ECU, the ESP system may fail
to function as intended. Serious vehicle braking and performance issues could
result, including unnecessary ESP system interventions, exceeding regulated
stopping distance, and/or system faults leading to loss of system functions. These
types of failures can lead to loss-of-control of the vehicle and/or collisions causing
property damage, serious injuries, or death.

F3.0

Potential False Alerts – The Bendix® Fusion™ system may generate a false alert
or false braking. Radar and camera technology has limitations and false alerts or
false braking sometimes occur.
The Fusion system DOES NOT respond to stationary objects. The system will not
slow your vehicle or provide an alert as you approach stationary objects.
Animals, Non-Metallic, or Limited-Metallic Objects – The Fusion system will not
warn or react to animals, or non-metallic objects. The system may not warn or react
to limited-metallic objects (such as recreational vehicles, horse-drawn buggies,
motorcycles, logging trailers, etc.).
The Pedestrian Autonomous Emergency Braking (PAEB) feature can only detect
pedestrians or cyclists in the path of the host vehicle and it is important to note
that pedestrians or cyclists are not instantly detectable, nor are they always
detectable. Objects other than pedestrians or cyclists outside the vehicle’s path
will not trigger a reaction by the system.
The system should never be relied upon to stop your vehicle or to avoid a collision.
You can, and should, still apply full braking force, if needed.
Metallic objects may impair the radar. Objects that are radar-reflective – such
as crash barriers, guard rails, construction zone barricades, and tunnel
entrances – may impair the function of the radar.
Approach grades as you would normally, with the appropriate gear selected and
at a safe speed. Active Cruise with Braking (ACB) SHOULD NOT be used on steep
downhill grades. Follow all safe driving practices.
Inspect the radar and mounting bracket regularly and remove any mud, snow, ice
build-up, debris, or other obstructions that may be blocking the radar. Installing
aftermarket deer, bumper, or grille guards is not recommended and could impair
the operation of the radar.
If the bumper and/or radar are damaged or misaligned – or if the radar was
tampered with – do not use ACB until the vehicle is repaired.
If a problem is detected with the Fusion system, there is an audible alert and/or an
icon on the display. Depending on the type of problem, the system may disable
ACB functions or other safety functionality until service is performed.
Smaller forward vehicles – such as motorcycles and certain types of trailers – may
be difficult for the system to identify. As the driver, it is your responsibility to be
aware of these types of vehicles, to be cautious, and to slow down if necessary.
As the driver, you are always responsible for the safe operation of the vehicle
and you should be aware of potential threats that may enter the vehicle’s lane of
travel. As the driver, you should always be alert and ready to intervene.
Service Brake Hold is not a parking brake. After any Bendix safety system braking
that brings the vehicle to a complete stop, you, the driver, must intervene. As the
driver, you should use caution and manually apply the parking brake as needed.

SYSTEM FEATURES
NOTE: You should check with the vehicle OEM to verify which features are
included on your vehicle.
IMPORTANT FEATURE INFORMATION: DRIVER OVERRIDE
Some driver actions can override Bendix® Fusion™ system activations. Once an Active
Cruise with Braking (ACB) or Autonomous Emergency Braking (AEB) event has started,
you, the driver, can override its activation. Refer to each specific feature section of
this Operator’s Manual for overrides specific to that feature.
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.
Active Cruise with Braking (ACB)
NOTE: The term ACC (Adaptive Cruise Control) may be used instead of – or
interchanged with – ACB.
When normal cruise control is on and set, the ACB feature also becomes available.
The system may not only intervene to maintain the ACB set speed, but also may
potentially intervene – if needed – to maintain a set following distance behind the
detected forward vehicle in front of you.
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.
NOTE: You, the driver, can override an ACB system intervention by applying the
accelerator pedal. ACB will be overridden until the accelerator is released; then, ACB
will resume the original set speed and distance control automatically.
When you encounter a detected forward vehicle that slows down below the ACB set
speed, 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 forward vehicle. The following distance may be adjustable on some
vehicles. See Figure 4.

Auto-Resume™ after Active Cruise with Braking (ACB)
If Active Cruise with Braking (ACB) is on and set, the Bendix® Fusion™ system may
automatically apply the service brakes during an ACB braking event in order to
maintain the distance between your truck and the detected forward vehicle. If
your vehicle remains above the minimum ACB set speed as defined by the OEM,
your vehicle may automatically accelerate back up to the ACB set speed while still
attempting to maintain the set following distance with the forward vehicle. If your
vehicle is below the minimum defined ACB set speed, ACB may automatically cancel
and will not attempt to adjust the vehicle speed.
NOTE: Vehicles equipped with ACB Stop and Auto-Go™ do not have a minimum
defined speed and may auto-resume at very low speeds.
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.
Canceling ACB
NOTE: At any time, you, the driver, can
step on the brake pedal or turn ACB off
via the switch to cancel the ACB feature.
Figure 5 shows an integrated display
message you may see when ACB is Figure 5 – ACB Actively Engaged and
actively engaged and maintaining a set Maintaining Set Following Distance
following distance behind the detected
forward vehicle.
Additionally, Figure 6 shows a message
you may see on the integrated display
when the ACB function cancels, and
the Autonomous Emergency Braking
(AEB) system is monitoring the detected Figure 6 – ACB Canceled, AEB Detecting the
Forward Vehicle
forward vehicle.
If your vehicle speed is below the
OEM-defined minimum speed for AEB operation, the ACB display may be blank.
Alerts and messages will come from the OEM 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.
NOTE: The term CMS (Collision Mitigation System) may be used instead of – or
interchanged with – AEB.

Active Cruise with Braking (ACB) Stop and Driver-Go™
NOTE: This feature only applies to
vehicles equipped with Active Cruise
with Braking (ACB) Stop and Driver-Go™.
When ACB is on and set, if the detected
forward vehicle slows down to a stop, the
system may automatically de-throttle
Figure 7 – ACB Actively Engaged
the engine, activate the engine retarder,
and apply the service brakes to bring
your vehicle to a full stop. You, the driver,
can resume ACB by pressing down on the
throttle. The vehicle will accelerate back
up to the previous ACB set speed while
maintaining the distance between your
truck and the detected forward vehicle.
Figure 7 shows a message you may see
on the integrated display when the ACB
function is actively engaged.
If you do not press down on the throttle Figure 8 – ACB Canceled - Take Vehicle
Control
within a few seconds, the service brakes
will hold the vehicle at a stop until you,
the driver, intervene.
NOTE: You, the driver, can press the brake pedal, apply the parking brake, or you can
manually accelerate the vehicle by pressing down on the accelerator pedal.
When the vehicle reaches the minimum ACB set speed defined by the OEM, you
can press the resume button to accelerate back up to the previous ACB set speed.
Figure 8 shows a message you may see on the integrated display when the ACB
Stop and Driver-Go function cancels and you, the driver, must intervene. Alerts and
messages will come from the OEM 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.

Active Cruise with Braking (ACB) Stop and Auto-Go™
NOTE: Certain vehicles with certain engine/powertrain combinations, may be
equipped with Active Cruise with Braking (ACB) Stop & Auto-Go™ functionality.
Under certain circumstances, after a normal ACB stop, ACB Stop & Auto-Go may
automatically accelerate the vehicle up to the previously set ACB speed without
additional driver input while also attempting to maintain the set following distance
between your vehicle and the detected forward vehicle.
After a normal ACB stop, the service brakes may hold the vehicle at a stop (refer to
the Service Brake Hold section of this document). If the detected forward vehicle moves
forward within a few seconds and a
pedestrian is not detected, your vehicle
may accelerate back up to the previously
set ACB speed while attempting to
maintain the set following distance
between your vehicle and the detected
forward vehicle. See Figure 9.
Figure 9 – ACB Actively Engaged

The Bendix® Fusion™ system may react to
detected pedestrians in the vehicle path
during ACB Stop and Auto-Go. In this
scenario, the Pedestrian Autonomous
Emergency Braking (PAEB) feature may
warn or brake the vehicle. The Fusion
system can only detect pedestrians in
the vehicle’s path and it is important to Figure 10 – PAEB Feature Alert
note that pedestrians are not instantly
detectable.

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 (Service Brake Hold) until you, the
driver, intervene.
NOTE: You, the driver, can intervene by pressing the accelerator pedal or the brake
pedal, pressing the ACB resume button, or applying the parking brake.
Figure 10 shows an example of the message you may see on the integrated display
when the Impact Alert (IA) or PAEB feature is activated.
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.

11

F3.0

If the detected forward vehicle does not
move forward within a few seconds and
there is not a detected pedestrian, the
driver may see a Paused Cruise Control
message on the dash display. See Figure
11. The service brakes will hold the Figure 11 – Paused Cruise Control
vehicle at a stop until you, the driver,
intervene.
NOTE: You, the driver, can intervene by pressing the accelerator pedal or the brake
pedal, pressing the Active Cruise with Braking (ACB) resume button, or applying the
parking brake.
The ACB feature will automatically re-engage and will accelerate back up to the ACB
set speed. It should be noted that stepping on the brake will cancel ACB and the
ACB resume function.
In addition to a pedestrian being detected, the ACB Stop and Auto-Go™ feature may
also cancel and the brake hold may activate under any of the following circumstances:
•

If the forward vehicle is no longer detected

•

If the turn signal is activated

•

If the hazard lights are activated

•

If the steering system input indicates the vehicle is planning to turn

Passing a Vehicle / Changing Lanes
The accelerator pedal can be applied to pass a vehicle at any time while the ACB
system is active.

When No Forward Vehicle is Present
When ACB is switched on and set and no forward vehicle is within range of the
Bendix® Fusion™ system, the vehicle will use standard cruise control to help maintain
the set speed.

F3.0

12

The Detected Forward Vehicle Icon
When Active Cruise with Braking (ACB)
is switched on and set, and a vehicle
ahead of you is detected by the system,
the detected forward vehicle icon on
the vehicle display will illuminate. See Figure 12 – Detected Forward Vehicle
Figure 12. This is an indication to you that
the Bendix® Fusion™ system detected
the forward vehicle, and the system may
automatically intervene to help maintain the distance.

What is Following Distance?
Following distance refers to the time gap – measured in seconds – between the
vehicle equipped with the Fusion system and the detected vehicle ahead. The
following distance between the two will vary based on the speeds of both vehicles.
This physical distance is sometimes referred to as “headway.”

Automatic Service Brake Applications
The vehicle automatically manages service braking priorities among the various
Bendix® vehicle systems that automatically use the service brakes, such as the Bendix®
Electronic Stability Program (ESP®), Bendix® Automatic Traction Control (ATC), Bendix®
Antilock Braking System (ABS), and the Fusion system.
NOTE: Vehicle stability has priority over all other braking requests.

F3.0

When Not to Use Active Cruise with Braking (ACB)
This vehicle’s Active Cruise with Braking (ACB) system must only be used in
the same conditions that are normally recommended for ACB systems that
do not have active, adaptive, or predictive systems. DO NOT USE ACB IN THE
FOLLOWING SITUATIONS:
Inclement Weather/Low Visibility Situations – Do not use ACB in
inclement weather or low visibility conditions – such as rain, snow,
smoke, fog, ice, or other severe weather conditions.
Dense Traffic – Follow all safe driving practices.

City/Local Roads – Follow all safe driving practices.
Sharp Curves and Winding Roads – Do not use ACB when traveling
sharply curved or winding roadways. CAUTION: Road curvature
may impact the radar sensor’s ability to detect forward vehicles in
the same lane.
Entrance or Exit Ramps – Follow all safe driving practices.

Downhill Grades – Follow all safe driving practices.

Construction Zones – Do not use ACB in construction zones.

Off-Road – Do not use ACB in off-road conditions.

Service Brake Hold
NOTE: The Service Brake Hold function is
only available on vehicles equipped with
ACB Stop and Auto-Go™ and ACB Stop
and Driver-Go™.
If, as a result of the Bendix® Fusion™
system brake intervention, the vehicle
comes to a full stop, the service brakes
may hold the vehicle at a stop until you,
the driver, intervene
Figure 13 – Service Brake Hold
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 not a parking brake and you must intervene.
If after a set period of time the driver does not respond, the integrated display may
show a driver intervention request. See Figure 13.
If you choose to exit the vehicle, you are responsible for setting the parking brakes.
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.

15

F3.0

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 14 - 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
14 shows messages you may receive on
