THE BENDIX® ESP® STABILITY SYSTEM
All vehicles equipped with the Bendix® Fusion™ system are also equipped with the
Bendix® 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-of-control 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
Feature Removal: This version of the Bendix® Fusion™ system can read most – but
not all – roadside speed limit signs in the United States. The Fusion system will not
dethrottle the engine under any circumstance, including + 10 mph (16 kph) over
the detected speed limit. It is only capable of providing audible and visual alerts to
the driver.
New Functionalities Added: This version of the Bendix Fusion system includes two
(2) new functionalities: Pedestrian Autonomous Emergency Braking (PAEB) 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 (OA), 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 the 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 Original Equipment Manufacturer (OEM) to
determine which features are included on your vehicle.
IMPORTANT FEATURE INFORMATION: DRIVER OVERRIDE
Some driver actions can override Bendix® Fusion™ system activations. Once an
Autonomous Emergency Braking (AEB) event has started, you, the driver, can override
its activation. Refer to each 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 cruise control 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.

active, the set speed is displayed in white numbers.

Auto-Resume™ after Active Cruise with Braking (ACB)
If 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 Original Equipment Manufacturer (OEM), your
vehicle may automatically accelerate back up to the previous ACB set speed while
still attempting to maintain the set following distance with the forward vehicle.
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 Active Cruise with
Braking (ACB)
At any time, you, the driver, can step on
the brake pedal or turn Active Cruise
with Braking (ACB) off via the switch to
cancel the ACB feature.
Figure 6a shows an integrated display
message you may see when ACB is off Figure 6a – ACB Off - Set Available
and not set. Figure 6b shows a message
you may see on the integrated display
when ACB is on and maintaining the set

the integrated display when the ACB
function cancels and the ACB feature
is available for you, the driver, to re- Figure 6b – ACB On, Actively Engaged, and
engage. Alerts and messages will come Maintaining Set Following Distance
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.
Figure 6c – ACB Off - ACB Available
to Re-engage

Active Cruise with Braking (ACB) Stop and Auto-Go™
NOTE: Certain vehicles with certain engine/powertrain combinations, may be
equipped with ACB Stop and Auto-Go™ functionality. Under certain circumstances,
after a normal ACB stop, ACB Stop and Auto-Go may automatically accelerate the
vehicle up to the previous ACB set 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 on page 15 for more details). 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 previous ACB set speed while attempting to
maintain the set following distance between your vehicle and the detected forward
vehicle. See Figure 7.
F3.0

10

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
note that pedestrians are not instantly Figure 7 – ACB On, Actively Engaged, and
Maintaining Set Following Distance
detectable.
If, as a result of the Pedestrian
Autonomous Emergency Braking (PAEB)
feature, 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. Figure 8a – PAEB Feature Alert
NOTE: You, the driver, can intervene
by pressing the accelerator pedal
or the brake pedal, or applying the
parking brake. Figures 8a and 8b show
examples of messages 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 Figure 8b – Possible Autonomous
Emergency Braking Applied
safe operation of the vehicle and you
should be alert and ready to potentially
intervene.
If the detected forward vehicle does not move forward within a few seconds and
there is not a detected pedestrian, the service brakes will hold the vehicle at a stop
until you, the driver, intervene. NOTE: You, the driver, can intervene and cancel the
system operation by pressing the brake pedal or applying the parking brake. If the
driver intervenes with the accelerator pedal or ACB resume button, the ACB feature
will automatically re-engage and will accelerate back up to the previous 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 while the vehicle is stopped, the ACB
Stop and Auto-Go™ feature may also cancel and the Service 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 Active
Cruise with Braking (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.
The Detected Forward Vehicle Icon
When ACB is switched on and set, and a
vehicle ahead of you is detected by the
system, the detected forward vehicle Figure 9 – Detected Forward Vehicle Icon
icon on the vehicle display will illuminate.
See Figure 9. 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.

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.

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 (e.g., < 10 mph), 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, Figure 10a – AEB System Alert
and you should take immediate
action to potentially avoid – or lessen
the severity of – the potential 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 Figure 10b – Possible Autonomous
to the trailer brakes – if needed – to help Emergency Braking Applied
mitigate or lessen the severity of the
potential collision.
When activated, you may be notified by an audible and visual indication from the OEMintegrated display. 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. Service Brake Hold is only available on vehicles equipped
with ACB Stop and Auto-Go™.
Figures 10a and 10b show examples of messages you may see on the integrated
display when the IA or AEB 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.
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. For
more information on system limitations, refer to BW8107, Challenging Scenarios, on
B2Bendix.com or the section “Potentially Challenging Situations for the Bendix Fusion
System” in this Operator’s Manual.

Pedestrian Autonomous Emergency Braking (PAEB)
At low vehicle speeds, the Bendix® Fusion system may react to a detected stationary
or moving pedestrian or cyclist 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 below approximately
35 mph (56 kph). The alert indicates
that a collision with the pedestrian or
cyclist may be likely, and you should take
immediate action to potentially avoid –
or lessen the severity of – the potential
collision.
If you, the driver, do not address the Figure 11a – AEB System Alert
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 help mitigate or lessen the
severity of the potential collision.
