BENDIX® FUSION™ ACTIVE
SAFETY SYSTEM WITH ACB
(ACTIVE CRUISE WITH BRAKING)
STOP AND AUTO-GO™
OPERATOR’S MANUAL
This booklet contains important operational and safety information that benefits you and subsequent drivers.
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, Bendix ESP automatically
intervenes to reduce the accelerator pedal input and/or apply the foundation 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
brake applications.
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 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 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, camerabased safety technology may not be able to detect or may misinterpret
lane markings. At these times, alerts may not occur, or erroneous alerts
may occur.
The Bendix Fusion system reacts ONLY to vehicles that are stationary or
moving in the same direction as your vehicle. The Fusion 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
Figure 2 - System Responses
When the Fusion system needs to intervene, it works in conjunction with
the Bendix® ESP® full stability system to engage the foundation brakes.
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.
Potential False Alerts – The Fusion system may generate a false alert or
false braking. Radar and camera technology is not perfect, and false alerts
sometimes occur.
5
Pedestrians, Animals, Non-Metallic, or Limited-Metallic Objects – The
Bendix® 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 Fusion system may react to pedestrians in the vehicle
path during ACB (Active Cruise with Braking) Stop and Auto-Go™.
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 radarreflective – 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. Caution is advised if you, the driver, decide
to use ACB during downhill grades. Follow all safe driving practices. ACB
should not be used on hills greater than OEM recommendations.
Inspect the radar and mounting bracket regularly and remove any mud,
snow, ice build-up, or other obstructions. Installing aftermarket deer or
bumper 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 cruise control until the vehicle is repaired
and the radar is re-aligned.
If a problem is detected with the Bendix® Fusion™ system, there is an
audible alert and/or icon on the display. Depending on the type of
problem, the system may disable cruise control functions until service is
performed.
Smaller forward vehicles, such as motorcycles, may be difficult for the
radar to identify. As the driver, it is your responsibility to be aware of this
type of vehicle and to be cautious.
As the driver, you should always be responsible for the safe operation of
the vehicle and 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 take
over.
Indefinite service brake hold is not a parking brake. After ACB, you, the
driver, must take over and secure the vehicle. As the driver, you should use
caution and manually apply the parking brake when parking the vehicle
on a steep grade or when exiting the vehicle.
The Fusion system DOES NOT respond to stationary objects – only
stationary vehicles. The system will not slow your vehicle or provide an
alert as you approach stationary objects.

Figure 3 - System Components
The Fusion system locates and tracks moving and stationary vehicles and objects. The
radar is located at the front of your vehicle. The camera is located on the windshield,
inside the wiper path.
The Fusion system radar is pre-aligned at the factory and no adjustment should be
needed. If the radar becomes misaligned – or any other system problem is detected
– a message (or light) on the display lets you know that service is needed.
SYSTEM DISPLAY
Driver information about the Fusion system is fully integrated into the vehicle display.
See the System Features section of this manual for more detailed information about
the alerts.

SYSTEM FEATURES
Active Cruise with Braking (ACB)
NOTE: Some OEMs use the term ACC (Active Cruise Control) instead of ACB.
When normal cruise control is on and set, as confirmed by the green cruise control
icon on the display, the ACB feature also becomes available. The system will not
only intervene to maintain the cruise control set speed, but also can intervene – if
needed – to maintain a set default following distance behind the moving vehicle
in front of you.
When you encounter a detected forward vehicle that slows down below the cruise
control set speed, the system has the ability to decrease the accelerator pedal
input, apply the retarder, or activate the foundation brakes – if needed – in order to
maintain the gap with the forward vehicle. The following distance is adjustable on
some vehicles. See the striped area in Figure 4.
Detected forward
vehicle
NOT TO SCALE
The STRIPED area approximates the
zone where the ACB feature is ready to
alert – and intervene with the vehicle’s
brakes – when the cruise control is set.
The DARK GREY area approximates
the zone where the Bendix® Fusion™
system is ready to alert – and intervene
with the vehicle’s brakes – at all times.
Figure 4 - ACB
Auto-Resume™ after an ACB Event
If the Fusion system automatically applies the foundation brakes in order to maintain
the gap with the forward vehicle, and the vehicle remains above a minimum speed
defined by the OEM, the vehicle will “auto-resume” back to the cruise control set
speed while still attempting to maintain the set following distance gap with the
forward vehicle. The cruise control icon will remain green, indicating cruise control
is engaged. If the vehicle is below the minimum defined speed, cruise control will
automatically cancel and will not attempt to adjust the speed to the previously set
speed. The cruise control icon will change to white, indicating cruise control is not set.
NOTE: As the driver, you should always be alert and ready to take over.
8
Canceling Cruise Control and Active Cruise with Braking (ACB)
At any time, you can step on the brake
pedal, press “cancel,” or turn cruise
control off via the switch to cancel cruise
control and the ACB (Active Cruise with
Braking) Auto-Resume™ feature.
Figure 5 shows an integrated display
message you may see when the ACB
and the ACB Auto-Resume feature are
actively engaged and maintaining a set
following distance behind the forward
vehicle. Additionally, Figure 5 shows a
message you may see on the integrated
display when ACB and the ACB AutoResume function cancel, and ACB is
monitoring the forward vehicle. Alerts
and messages will come from the OEM
display. Please verify with the vehicle
Operator’s Manual for the actual audible Figure 5 - Canceling Cruise Control
and visual indications your vehicle may and ACB
display.
NOTE: As the driver, you should always be alert and ready to take over.
ACB Stop and Auto-Go™
When cruise control is on and set, if the
detected forward vehicle slows down to
a stop, the system can automatically dethrottle the engine, activate the engine
retarder, and apply the foundation
brakes to bring the vehicle to a full stop.
If the detected vehicle in front of your
vehicle moves forward within the ACB
Auto-Resume time period and an object
Figure 6 - ACB Stop and Auto-Go
or pedestrian is not detected between
the front of your vehicle and the detected
forward vehicle, your vehicle will “auto-resume” and return back to the cruise control
set speed while attempting to maintain the set following distance with the forward
vehicle. Figure 6 shows a message you may see on the integrated display when the
ACB Auto-Resume function is actively engaged during the ACB Stop and Auto-Go
function.
NOTE: Confirm the auto-resume time period with your OEM.
9
NOTE: The Bendix® Fusion™ system may
react to pedestrians in the vehicle path
during ACB (Active Cruise with Braking)
Stop and Auto-Go™. Figure 7 shows a
message you may see on the integrated
display indicating a pedestrian or object
has been detected.
If the detected forward vehicle does
not move within the auto-resume time Figure 7 - Pedestrian Detection
period, the ACB Auto-Resume™ function
will cancel and the foundation brakes will hold the vehicle at a stop indefinitely. You,
the driver, must take over. You can manually speed up the vehicle by pressing down
on the accelerator pedal or pressing the cruise control resume switch. The ACB system
will automatically re-engage upon reaching the vehicle’s minimum cruise control set
speed defined by the OEM and will “auto-resume” back to the cruise control set speed.
Figure 8 shows a message you may see
on the integrated display when the ACB
Auto-Resume function cancels and ACB
is monitoring the forward vehicle. Alerts
and messages will come from the OEM
display. Please verify with the vehicle
Operator’s Manual for the actual audible
and visual indications your vehicle may
display.
NOTE: As the driver, you should always Figure 8 - ACB Auto-Resume
be alert and ready to take over.
Cancelation
NOTE: The indefinite service brake hold
can be canceled if you, the driver, press the accelerator pedal or the brake pedal,
apply the parking brake, or resume cruise control.
NOTE: Indefinite service brake hold is not a parking brake. As the driver, you must
take over and secure the vehicle.
10
If the system detects a pedestrian between your vehicle and the detected forward
vehicle, the Active Cruise with Braking (ACB) function will cancel and the foundation
brakes will hold the vehicle at a stop indefinitely. As the driver, you must take over.
This function can only detect pedestrians within the radar field of view and it is
important to note that the pedestrians are not instantly detectable. You, the driver,
should always be responsible for the safe operation of the vehicle and be aware of
potential threats that may enter the vehicle’s lane of travel. ACB and the ACB AutoResume™ feature should not be used in city environments with a high occurrence
of pedestrians or other objects crossing in front of the vehicle. The Auto-Resume
feature will also cancel under any of the following circumstances:
•
If the forward vehicle tracking is lost
•
If the turn signal is activated
•
If the hazard lights are activated
•
If 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 Vehicles are Present
When cruise control is switched on and set and no forward vehicle is within range
of the Bendix® Fusion™ system, the vehicle will maintain the set speed like ordinary
cruise control.
The Forward Detected Vehicle Icon
When cruise control is switched on and set, and a vehicle
ahead of you is detected by the system, the forward detected
vehicle icon on the vehicle display will illuminate. See Figure 9.
This is an indication to you that the Fusion system is actively
managing the distance between your vehicle and the vehicle
ahead, and that the system may automatically intervene.
11
Figure 9 - Forward
Detected Vehicle
Icon
What is Following Distance?
Following distance refers to the time gap – measured in seconds – between the
vehicle equipped with the Bendix® Fusion™ system and the detected vehicle ahead.
The actual physical distance between the two will vary based on the speeds of both
vehicles. This physical distance is sometimes referred to as “headway.”
Automatic Foundation Brake Applications
The vehicle automatically manages foundation braking priorities among the various
vehicle systems that use the foundation brakes, such as the Fusion system, Bendix®
Electronic Stability Program (ESP®), Bendix® Automatic Traction Control (ATC), and
Bendix® Antilock Braking System (ABS).
12
When Not to Use Cruise Control
This vehicle’s cruise control must only be used in the same conditions that
are normally recommended for ordinary cruise control. THERE ARE CERTAIN
SITUATIONS WHEN CRUISE CONTROL SHOULD NOT BE USED:
Inclement Weather/Low Visibility Situations – Do not use cruise
control in inclement weather or low visibility conditions – such as
rain, snow, smoke, fog, ice, or other severe weather conditions – that
may affect the performance of the Bendix® Fusion™ system.
Dense Traffic – Caution is advised if you, the driver, decide to use ACB
(Active Cruise with Braking) in dense traffic. Follow all safe driving
practices.
Sharp Curves and Winding Roads – Do not use cruise control when
traveling sharply curved or winding roadways. CAUTION: Road
curvature may impact the radar’s ability to track vehicles ahead in
the same lane.
Entrance or Exit Ramps – Caution is advised if you, the driver, decide
to use cruise control when entering or exiting roadways. Follow all
safe driving practices.
Downhill Grades – Caution is advised if you, the driver, decide to use
ACB during downhill grades. Follow all safe driving practices. ACB
should not be used on hills greater than OEM recommendations.
Construction Zones – Do not use cruise control in construction zones.
Off-Road – Do not use cruise control in off-road conditions.
Smaller Forward Vehicles – Smaller forward vehicles, such as
motorcycles, or certain types of trailers, may be difficult for the radar
and camera to identify. It is your responsibility to be aware of these
types of vehicles and to slow down if necessary.
13
Impact Alert (IA) and Autonomous Emergency Braking (AEB)
This is the most severe warning and
action the Bendix® Fusion™ system can
make. The alert indicates that a collision
with the detected forward vehicle is
likely, and you should take immediate
action to potentially avoid – or lessen
the severity of – the potential collision.
If you do not address the potential
forward collision, the Fusion system may
automatically apply up to full foundation
brakes on the tractor while pulsing
the trailer brakes – if needed – to help
mitigate or lessen its severity.
When activated, you will be notified by Figure 10 - IA and AEB
an audible and visual indication from the
OEM-integrated display.
Figure 10 shows examples of messages you may see on the integrated display when
the IA or AEB is activated. Please verify with the vehicle Operator’s Manual for the
actual audible and visual indications your vehicle may display.
NOTE: As the driver, you should always be alert and ready to take over.
Indefinite Service Brake Hold
If, as a result of the Fusion system
intervention, the vehicle comes to a full
stop, the foundation brakes will hold the
vehicle at a stop indefinitely and you, the
driver, must take over. Indefinite service
brake hold is not a parking brake and you
must take over and secure the vehicle. If Figure 11 - Indefinite Service Brake
after a set period of time the driver does Hold
not respond, the integrated display will
show a driver takeover request (See Figure 11). As the driver, you should use caution
and manually apply the brakes on steep grades or when exiting the vehicle. You, the
driver, can manually launch the vehicle by pressing down on the accelerator pedal.
NOTE: As the driver, you should never exit the vehicle without first securing the
vehicle parking brake.
NOTE: As the driver, you should always be alert and ready to take over.
NOTE: The indefinite service brake hold can be canceled if you, the driver, press the
accelerator pedal or the brake pedal, or apply the parking brake.
14
Slower Moving Vehicles Ahead
The Bendix® Fusion™ system is ready to intervene with braking, as needed, if the
system determines that a potential collision with a slower moving vehicle ahead is
imminent. You, the driver, must apply additional braking when necessary to maintain
a safe distance with the vehicle ahead. When approaching a slower moving vehicle
ahead, you should anticipate this and take necessary action. Do not wait for the
system to intervene!
Stationary Vehicle Braking (SVB)
When a potential collision with a large, stationary, metallic vehicle in your lane of
travel (definitively identified as a vehicle) is detected, the system can sound an alert
before impact.
If you don’t take action to address the potential impact, the Fusion system can apply
foundation brakes to assist you in reducing the severity of or potentially avoiding
the collision with that stationary vehicle.
If, as a result of the Fusion system intervention, the vehicle comes to a full stop, the
foundation brakes will hold the vehicle at a stop indefinitely and you, the driver, must
take over. Indefinite service brake hold is not a parking brake and you must take over
and secure the vehicle. As the driver, you should use caution and manually apply the
brakes on or when exiting the vehicle. You, the driver, can manually accelerate the
vehicle by pressing down on the accelerator pedal.
NOTE: As the driver, you should always be alert and ready to take over.
NOTE: The indefinite service brake hold
can be canceled if you, the driver, press
the accelerator pedal or the brake pedal,
or apply the parking brake.
The stationary vehicle braking feature
of the Fusion system’s Autonomous
Emergency Braking (AEB) is most useful
when approaching a line of stopped
traffic or a stalled vehicle that is not
immediately recognized by a distracted
driver. This includes conditions such as
while driving in limited-sight conditions,
at night, or in fog.
Figure 12 - IA and AEB
Figure 12 shows examples the messages
you may see on the integrated display when the Impact Alert (IA), or AEB, is activated.
Please verify with the vehicle Operator’s Manual for the actual audible and visual
indications your vehicle may display.
NOTE: As the driver, you should always be alert and ready to take over.
15
Multi-lane Autonomous Emergency Braking (AEB)
See Figure 13. Not only can the Bendix® Fusion™ system potentially mitigate a forward
collision with an in-lane vehicle, it can also help you mitigate one when more than one
highway lane is blocked. Once a collision mitigation braking event begins and you, as
the driver, steer into an adjacent lane to avoid the forward vehicle, the Fusion system’s
Multi-lane AEB feature may continue to apply the brakes and sound an alert when
it detects another forward vehicle ahead posing a threat in the new lane of travel.
If, as a result of the Fusion system intervention, the vehicle comes to a full stop, the
foundation brakes may hold the vehicle at a stop indefinitely and you, the driver,
must take over. Indefinite service brake hold is not a parking brake and you must
take over and secure the vehicle. As the driver, you should use caution and manually
apply the brakes on or when exiting the vehicle. As the driver, you can manually
accelerate the vehicle by pressing down on the accelerator pedal.
NOTE: As the driver, you should always be alert and ready to take over.
NOTE: The indefinite service brake hold can be canceled if you, the driver, press the
accelerator pedal or the brake pedal, or apply the parking brake.
The Fusion system’s Multi-lane AEB
feature can help you, the driver, mitigate
both the first, and potentially the
second, crash situation when more than
one traffic lane is blocked.
Figure 13 - Multi-lane AEB
16
Following Distance Alerts (FDA)
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 whenever the distance between
your vehicle and the detected forward
vehicle is getting closer and you are
within the alert range.
Once the audible alert is given, you

Challenging Situations
The Bendix® Fusion™ system does not automatically apply foundation brakes on
stationary objects – only stationary vehicles as previously described.
Also, the Fusion system may not be able to detect objects with limited radar-reflecting
surfaces or materials such as recreational vehicles, horse-drawn buggies, motorcycles,
logging trailers, etc. As the driver, you are responsible for the safe operation of the
vehicle at all times.
Lane Departure Warning (LDW)
The Fusion system has the ability to warn you if your vehicle unintentionally departs
its lane by emitting an audible rumble strip sound to get your attention.
I n m os t ap p li c ati o ns , th e LDW s y s te m is e nab l e d ab ove 37 mp h
(60 kph). If the turn signal is used to change lanes, the LDW is suppressed and no
audible or visual alerts are activated. You should always be ready to immediately
correct the vehicle lane position, especially when the LDW is activated.
Figure 17 shows integrated display messages you may see from the LDW system.
A. The LDW function is detecting the lane lines
B. T he vehicle speed is below 37 mph (60 kph) and the LDW system is not
activated
C. The vehicle is traveling over a lane marking without a turn signal
D. The LDW function is disabled or faulted
Please verify with the vehicle Operator’s Manual for the actual audible and visual
indications your vehicle may display.
NOTE: As the driver, you should always be alert and ready to take over.

NOTE: When making lane changes, the proper use of the turn
signals and hazard lights ensures the Bendix® Fusion™ system
LDW (Lane Departure Warning), Highway Departure Warning
(HDW), and Highway Departure Braking (HDB) technologies are
aware of the driver’s intention to depart a lane and will suppress
alerts.
The vehicle is equipped with a 15-minute LDW, HDW, and HDB
disable switch that you can activate when driving on roads Figure 18 - LDW
with inconsistent lane markings that can cause excessive false Disable Switch
warnings. Examples would include construction zones, poorly
marked lanes, or missing lane markings. The system alerts will automatically become
available again after 15 minutes.
Highway Departure Warning (HDW)
Built on the Lane Departure Warning (LDW) functionality, HDW provides an audible
alert if the system determines your vehicle has unintentionally left the roadway.
In most applications, the HDW alert is enabled above 37 mph (60 kph). If this alert
is sounded, you should immediately correct the vehicle path into the correct lane
position.
Highway Departure Braking (HDB)
If the highway departure situation that caused the HDW is not addressed, the Fusion
system may alert you by automatically applying the brakes to assist in reducing your
vehicle speed moderately. In some circumstances, the system may be capable of
reducing the vehicle speed to a full stop and indefinite service brake hold.
As the driver, you remain responsible for the safe operation of the vehicle at all times.
Figure 19 shows the message you may
see on the integrated display when
HDB is activated. Please verify with the
vehicle Operator’s Manual for the actual
audible and visual indications your
vehicle may display.
NOTE: HDW and HDB can only be
activated if the lane markings are
identifiable by the system.
Figure 19 - HDB
19
When HDW and HDB are activated excessively, the Bendix® Fusion™ system provides
a warning and will disable these functions until the driver restarts the vehicle. Other
Fusion system features, including LDW, will remain available.
If, as a result of the Fusion system intervention, the vehicle comes to a full stop, the
foundation brakes will hold the vehicle at a stop indefinitely and you, the driver, must
take over. Indefinite service brake hold is not a parking brake and you must take over
and secure the vehicle. You, the driver, should use caution and manually apply the
brakes on or when exiting the vehicle. You can manually accelerate the vehicle by
pressing down on the accelerator pedal.
NOTE: As the driver, you should always be alert and ready to take over.
NOTE: The indefinite service brake hold can be canceled if you press the accelerator
pedal or the brake pedal, or apply the parking brake.

Figure 20 - LDW, HDW, and HDB
Over-speed Alert and Action (OAA)
The Fusion system can read most roadside speed limit signs in North America and
can warn you if your vehicle speed exceeds the posted speed limit.
The OAA will sound an audible and visual alert to you when your vehicle is traveling
at +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 will experience a haptic warning through a brief engine torque
reduction of about one (1) second. A message will then be transmitted to fleet
management via the Bendix™ SafetyDirect® web portal.
20
Both the +5 and +10 mph thresholds are customizable by your
fleet and may vary. Also, the system does not sound an OAA when
the posted speed limit is 20 mph (32 kph) or less. When driving
between regions which post speeds in miles, and those which
post in kilometers, the speed sign recognition feature will not
function until the correct U.S./Metric selection is made or autolearned after detecting multiple speed signs in the new regions
(this is applicable to U.S. and Canada only).
Figure 21- OAA
Figure 21 shows a message you may see on the integrated Icon
display when the OAA is activated. Please verify with the vehicle
Operator’s Manual for audible and visual indications your vehicle
may display.
SPECIAL ALERTS
Brake Overuse Alert
The Bendix® Fusion™ system provides a warning when it is intervening and using
the foundation brakes excessively. Over use of the foundation brakes can lead to the
brakes overheating and a potential loss of braking performance caused by brake
fade. Using cruise control on downhill runs may cause this alert to activate. When
the system detects brake overuse, a text message will be shown on the display along
with an audible alert. As the driver, you should intervene immediately. Please verify
with the vehicle Operator’s Manual for the actual audible and visual indications your
vehicle may display.
Once the brake overuse alert is activated, certain driver interventions that cancel
cruise control – such as stepping on the brake pedal or switching off cruise control
– will discontinue the alert. Following a brake overuse alert, you should not reset
cruise control for at least 20 minutes. This will give the brakes time to cool down.
If you choose to reset cruise control during that 20-minute period, the Fusion system
interventions will be limited to de-throttling and engine retarder only. The system
will automatically disable all the Fusion system foundation brake applications for at
least 20 minutes.
If the system does not detect a driver intervention within 15 seconds after the brake
overuse alert sounds, it will shut itself off and set a Diagnostic Trouble Code (DTC).
You will continue to receive alerts, but all Fusion system interventions (de-throttling,
engine retarder, or brake applications) will be disabled until the next ignition cycle.
NOTE: In all cases, you have the ability to apply the foundation brakes if necessary. You
should take care since overheated brakes may reduce the vehicle’s braking capability.
21
POWER-ON SELF-TEST (POST)
During every power-on cycle, the Bendix® Fusion™ system executes a Power-On
Self-Test during which the driver assistance features described in this document are
not available. Vehicle cruise control is still available to the driver during POST. The
POST requires the vehicle speed to be above 4 mph (6 kph) and for the radar to see
objects to validate proper radar operation. Under normal operating conditions, the
POST completes within a few seconds and all driver assistance features become
available to the driver. In the special case where the radar is blocked, the POST will
not be able to verify normal system operation and, after two (2) minutes driving
under this condition, will set an active Diagnostic Trouble Code (DTC) rendering the
functionality of the Fusion system reduced or inoperable. Two (2) minutes under
this condition will lead to a radar fault code, but regular vehicle cruise control will
remain available to the driver.
SYSTEM RESPONSES
This chart illustrates how the system reacts to specific driver actions.
Your Action:
Reaction of the Bendix® Fusion™ System:
If you, the driver, do this:
Expect the Fusion system to do this:
Step on the brake (during a
collision mitigation event).
As the driver, you are always in control and are able to apply full
braking power.
Step aggressively on the
accelerator (during a
collision mitigation event).
As the driver, you are always in control. Your actions can override any
Fusion system actions. NOTE: If cruise control is engaged, it will be
overridden until the accelerator is released; then cruise control will
resume the original set speed automatically.
Step on the brake (when in
cruise).
Cruise control will be canceled.
Step on the brake or
accelerator pedal, or
activate the parking brake
(when in indefinite service
brake hold).
Indefinite service brake hold will be canceled. You, the driver, must
take over and secure the vehicle by pressing the accelerator pedal,
brake pedal, or parking brake as appropriate.
Step on the accelerator
(when in cruise).
Cruise control will be overridden until the accelerator is released;
then cruise control will resume the original set speed automatically.
Switch on the cruise
control.
Nothing. The ACB (Active Cruise with Braking) feature will not
engage until you set the cruise control speed.
Switch off the cruise
control.
The ACB feature will turn off; the collision mitigation feature remains
active and ready to intervene. You, the driver, will continue to hear
all alerts as needed.
Set the cruise control
speed.
The ACB feature is automatically activated, and your vehicle
maintains set speed and following distance behind the vehicle
ahead.
22
Your Action:
Reaction of the Bendix® Fusion™ System:
If you, the driver, do this:
Expect the Fusion system to do this:
Cover or block the radar.
The Fusion system performance will be diminished, or disabled,
when the radar becomes physically blocked. When the radar
can detect this condition, an alert will be issued to warn of this
condition. A blocked radar will be indicated through an alert and
will disable most Fusion system functions. Specific, camera-based
functions, such as Lane Departure Warning (LDW), will remain
operable. Conventional engine cruise control may be re-engaged
by the driver when the radar is disabled for blocked conditions.
It is important to visually inspect the radar and the mounting
bracket regularly and remove any mud, snow, ice build-up, or other
obstructions. After clearing any obstructions, turn the vehicle off
and then on to clear the fault code.
Cover or block the camera.
The Fusion system performance will be diminished, or disabled,
when the camera becomes blocked. An alert will be issued to alert
you of this condition.
A blocked camera will be indicated through an alert and will disable
all camera-based functions. The radar will maintain its function as a
Bendix® Wingman® Advanced™ system.
Use normal cruise control
“+/-” switch.
Vehicle speed will be increased (+) or reduced (-) to achieve the new
set speed, while actively maintaining the following distance with the
vehicle ahead, if one is present within 328 ft (100 m).
NOTE: The system responses described above are typical but may vary with different versions
of the Fusion system. These represent examples of driver actions and typical Fusion system
responses; however, this chart does not attempt to cover all possible situations.

POTENTIALLY CHALLENGING SITUATIONS FOR THE
BENDIX® FUSION™ SYSTEM
The following examples illustrate situations in which the Fusion system may issue
an alert or braking in a manner not consistent with your expectations. The Fusion
system may unexpectedly issue warnings, apply braking, or not respond.
Challenging Situation Examples
Driving Through a Curve or an
Exit Ramp
Example 1 - Driving Through a Curve
Other Vehicles
Partially Inside
your Lane of
Travel
Example 2 - Other Vehicles Ahead in your Lane of Travel
Turning Vehicles
Example 3 - Turning Vehicles
High Differences in Speed: The
higher the difference in speed
between the host truck and the
targeted forward vehicle, the less
time the system has to react. High
speed differences can cause little to
no system alert or activation.

Challenging Situation Examples (continued)
If stopped behind a stationary vehicle and the detected forward vehicle does not move within the
auto-resume time period, the ACB (Active Cruise with Braking) Auto-Resume™ function will cancel
and the foundation brakes will hold the vehicle at a stop indefinitely. You, the driver, must take over.
I f the system detects a pedestrian between your vehicle and the detected forward vehicle, the ACB
function will cancel and the foundation brakes will hold the vehicle at a stop indefinitely. As the
driver, you must take over.
The ACB Auto-Resume feature will also cancel under any the following circumstances:
•
If the forward vehicle tracking is lost
•
If the turn signal is activated
•
If the hazard lights are activated
•
If steering system input indicates the vehicle is planning to turn
Example 8 - ACB Auto-Resume does not Respond
Speed Only Mode
The per formance of the Bendix®
Fusion™ system may be diminished
or disabled when the radar becomes
blocked or has not detected a forward
vehicle for an extended period of time.
Figure 22 shows examples of alerts
that will be issued on the integrated
display to warn you of this condition.
Conventional engine cruise control
may be re-engaged by the driver when
the radar is disabled. Camera-based
functions, such as Lane Departure Figure 22 - Speed Only Mode
Warning (LDW) will remain.
32
Tracking Vehicles in a Curve
With cruise control set, when following a detected forward vehicle around a curve,
the forward detected vehicle tracking may be lost by the Bendix® Fusion™ system.
The ACB (Active Cruise with Braking) feature will delay acceleration back to the set
speed until one of the following events occur:
•
The system regains contact with the vehicle ahead;
•
The system detects that there is no longer a vehicle ahead; or
•
A time gap has occurred (based on the last following distance recorded).
F or example: Assume cruise control is set at 50 mph / 80 kph and you are
following 3 seconds behind a vehicle traveling at 45 mph / 72 kph that just
entered a sharp curve. If the vehicle ahead is no longer detected as you travel
around the curve, the Fusion system will delay the vehicle acceleration back
to 50 mph (80 kph).
It is also possible for the Fusion system to begin tracking vehicles in other lanes
when traveling around curves. In cases where the Fusion system perceives that an
adjacent-lane vehicle is in your lane, the system may intervene and begin making
brake applications.
SYSTEM MAINTENANCE AND TROUBLESHOOTING
Preventive Maintenance
The Fusion system is relatively maintenance-free. The key items to keep the system
functioning properly include:
•
 eep the area in front of the radar sensor and camera lens clean and free
K
of obstructions.
•
 isually inspect for any damage to the bumper or the Fusion cover, bracket,
V
or radar to ensure the alignment has not been compromised. Never use the
radar unit as a step.
33
When the Bendix® Fusion™ System Isn’t Working
If the Bendix® Fusion™ system has
detected a problem, depending on the
vehicle manufacturer, there will typically
be a warning message on the display, a
Diagnostic Trouble Code (DTC) will be
set, and you will be alerted. Figure 23
shows messages you may receive on the
integrated vehicle display.
The system will determine – depending
on the type of problem detected – if the
vehicle may continue to have normal
cruise control functions (without the
benefits of the Fusion system), or if all
cruise control functions need to be
disabled until the vehicle is serviced.
The system should be serviced as
soon as possible to restore full Fusion
functionality.
Figure 23 - Warnings
Equipment Maintenance
Importance of Antilock Braking System (ABS) Maintenance – Optimal
Bendix Fusion system braking requires a properly maintained ABS system,
without any active ABS Diagnostic Trouble Codes (DTCs). Have active DTCs
repaired by a qualified technician. Any ABS DTCs will cause the Fusion
system to deactivate.
Importance of Brake Maintenance – Optimal Fusion system braking
requires properly maintained truck foundation brakes (drum, wide-drum,
or air disc), which meet appropriate safety standards and regulations.
Brake performance also requires the vehicle be equipped with properly
sized and inflated tires with a safe tread depth.
Radar Inspection – You should visually inspect the radar and mounting
bracket regularly and remove any mud, snow, ice build-up, or other
obstructions. The installation of aftermarket deer guards, bumper guards,
snow plows, or similar potential obstructions is not recommended, and
could impair the operation of the radar. An alert will be issued when the
radar detects it is blocked. After clearing any obstructions, you will need
to turn the vehicle off and then on to clear the fault code.
34
Radar Damage / Misalignment / Tampering – In cases where the bumper
and/or radar have sustained any damage, are misaligned – or if you suspect
the radar has been tampered with – do not use the cruise control until
the vehicle has been repaired and the radar re-aligned. In addition, an
indicator on the display typically will illuminate if the system detects any
of these conditions. Consult your vehicle’s Operator’s Manual or contact
Bendix for more information.
Camera Inspection – The Bendix® Fusion™ system camera is mounted to
the windshield of the vehicle. The camera will be mounted inside the wiper
pattern and should be clear of any obstructions. An alert will be issued to
the driver when the camera is blocked. After clearing any obstructions,
you will need to turn the vehicle off and then on to clear the fault code.
ADDITIONAL OPERATIONAL NOTES
Adjusting the Alert Volume
The Bendix® Fusion™ system audible alerts are pre-set at the factory for fully
integrated systems and cannot be turned off by you, the driver. Depending on the
OEM, the volume may be adjustable.
Event Capture
In the case of vehicles configured to do so, the enable/disable switch used by the
system also functions – when depressed for six seconds – to activate a request
from the SafetyDirect® by Bendix CVS Processor on the On-board Computer (OBC)/
telematics system. The request captures, and possibly transmits, 10 seconds of video
data – the five seconds before and the five seconds after the button was pressed.
In some cases, more video data may be available using the SafetyDirect web portal
(subscription fee applies). A separate subscription to the SafetyDirect portal is needed
to view the video and data captured via a wireless connection.
SafetyDirect by Bendix CVS delivers actionable information that can help improve
fleet and driver safety. Data from the Fusion system’s brake sensors, camera, and
radar provides real-time knowledge and insight about your vehicle and surroundings
while on the road. Together with the SafetyDirect Processor (SDP), they collect
complex safety data and video that the SDP transfers to the SafetyDirect web portal
(safetydirectportal.com) for review.
The user-friendly, subscription-based SafetyDirect web portal captures that data
then, using your fleet’s telematics system, automatically transmits driver performance
and event-based information – including video – to your back office for analysis.
