NOTE: The Fusion system DOES NOT respond to stationary objects. The Fusion
system will not alert or slow the vehicle as it approaches stationary objects.
13

Service Brake Hold
NOTE: The Service Brake Hold functionality of Bendix® Fusion™ is only available on
vehicles equipped with Active Cruise with Braking (ACB) Stop and Auto-Go™.
If, as a result of the Bendix Fusion system brake intervention, the vehicle comes to a full
stop, the service brakes will hold the vehicle at a stop until you, the driver, intervene
via throttle, service brake application, or by setting the parking brakes. Service brake
hold is not a parking brake and you must intervene and secure the vehicle.
If you choose to exit the vehicle, you are responsible for setting the parking brakes.
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.
Slower Moving Vehicles Ahead
The Bendix Fusion system is ready
to potentially intervene with service
braking, as needed, if the system
determines that a potential collision with
a detected slower moving vehicle ahead
is imminent. However, you, the driver,
must apply additional braking or possible
steering when necessary to maintain
a safe distance with the vehicle ahead.
When approaching a slower moving
vehicle ahead, you should anticipate this
Figure 12 – Slower Moving Vehicle Ahead
and take necessary action.
DO NOT WAIT FOR THE SYSTEM TO
INTERVENE!
Figure 12 shows examples of the messages you may see on the integrated display
when the Following Distance Alert (FDA) and Impact Alert (IA), or Autonomous
Emergency Braking (AEB) feature, is activated.
NOTE: Dash display images are representative only and may not reflect the actual
vehicle display.

14

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 collision, the Bendix® Fusion™ system may reduce throttle
and apply service brakes to assist you in potentially avoiding and/or lessening the
severity of the potential collision with the detected stationary vehicle. If, as a result
of the Bendix Fusion system intervention, the vehicle comes to a full stop, the service
brakes will hold the vehicle at a stop until you, the driver, intervene. Service Brake
Hold is only available on vehicles equipped with Active Cruise with Braking (ACB)
Stop and Auto-Go™.
Service Brake Hold is not a parking brake and you must intervene and secure the
vehicle. As the driver, you should use caution and manually apply the parking brakes
when exiting the vehicle.
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 service brake hold can be canceled if you, the driver, press the accelerator
pedal or the brake pedal, or apply the parking brake.
NOTE: The Fusion system DOES NOT respond to stationary objects. Fusion will not
slow the vehicle or provide an alert as it approaches stationary objects.
Multi-lane Autonomous Emergency Braking (AEB)
See Figure 13. Once a collision mitigation braking event begins and you, as the driver,
steer into an adjacent lane to avoid the forward vehicle, the Bendix Fusion system’s
Multi-lane AEB feature may a) continue to apply the brakes, and b) sound an alert
when it detects a potential collision threat in the new lane of travel. If there is no
potential threat in the lane you swerve into, system intervention will stop.
The Bendix Fusion system’s Multi-lane
AEB feature may potentially help you,
the driver, mitigate both the first,
and potentially the second, collision
situation.

Figure 13 – Multi-lane AEB

15

If, as a result of the Bendix® 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
with a service brake application, throttle, or by setting the parking brake. Service
brake hold is only available on vehicles equipped with Active Cruise with Braking
(ACB) Stop and Auto-Go™. Service brake hold is not a parking brake and you must
intervene and secure the vehicle. As the driver, you should use caution and manually
apply the parking brakes when exiting the vehicle.
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 service brake hold can be canceled if you, the driver, press the accelerator
pedal or the brake pedal, or apply the parking brake.
Driver Override
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.
Some driver actions can override Fusion system activations. Once an Autonomous
Emergency Braking (AEB) event has started, you, the driver, can override its activation
by applying a significant change in accelerator position during the initial stage of
braking or by making a full throttle application. The system will respond with a
warning and some braking before AEB is suppressed.
Following Distance Alerts (FDAs)
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
until the audible alert stops.
The FDA is ready to alert you even when Figure 14 – FDA
the vehicle is moving at low speeds. If the
distance continues to decrease, the system will generate more rapid alerts. Figure 14
shows messages you may receive on the integrated display when the FDA is activated.

16

When the FDA reaches its highest level,
the beeping will be rapid. Figure 15
shows messages you may see on the
integrated display when the highest
level FDA and Impact Alert (IA) has been
activated.
NOTE: Dash display images are
representative only and may not reflect
the actual vehicle display.
NOTE: The Bendix ® Fusion™ system
DOES NOT respond to stationary
objects. Fusion will not alert or slow
the vehicle as it approaches stationary Figure 15 – Highest Level FDA and IA Alerts
objects. As the driver, you are responsible
for the safe operation of the vehicle at
all times. For more information, refer to
BW8107 Challenging Scenarios on b2bendix.com.
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 and a visual alert on the dash to get your attention. In
most applications, the Lane Departure Warning (LDW) feature is enabled above 37
mph (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 aware of your vehicle’s
lane position and be ready to immediately correct as needed.
Figure 16 shows integrated display messages you may see from the LDW feature.
This includes:
A. The LDW feature is detecting the lane lines.
B. T he vehicle speed is below 37 mph (60 kph) or the lane lines are not
detected.
C. The L DW indicates vehicle is departing the lane.
D. The LDW feature is disabled.
NOTE: Dash display images are representative only and may not reflect the actual
vehicle display.

Figure 16 – LDW Messages

NOTE: When making lane changes, the proper use of the
turn signals and/or hazard lights ensures the Bendix® Fusion™
system Lane Departure Warning (LDW), Highway Departure
Warning (HDW), and Highway Departure Braking (HDB)
technologies are aware of your intention to depart a lane
and will suppress alerts and braking. The vehicle is equipped
with a 15-minute LDW, HDW, and HDB disable switch
(Figure 17) that you can activate when driving on roads with Figure 17 – LDW,
inconsistent lane markings (that can cause excessive false HDW, and HDB
warnings). Examples of these circumstances include construction Disable Switch
zones, poorly marked lanes, or missing lane markings. The
system alerts will automatically become available again after 15
minutes or if the disable switch is pressed a second time.
Highway Departure Warning (HDW)
The Highway Departure Warning (HDW) feature may potentially provide 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.
NOTE: Dash display images are representative only and may not reflect the actual
vehicle display.

18

Highway Departure Braking (HDB)
If the highway departure situation that
caused the Highway Departure Warning
(HDW) is not addressed, the Bendix®
Fusion™ system may potentially apply the
brakes to assist in reducing your vehicle
speed. In some circumstances, the system Figure 18 – HDB
may be capable of reducing the vehicle
speed to a full stop.
Figure 18 shows the message you may see on the integrated display when Highway
Departure Warning (HDB) is activated. NOTE: Dash display images are representative
only and may not reflect the actual vehicle display.
If, as a result of the HDB feature, the vehicle comes to a full stop, the service brakes
will hold the vehicle at a stop until you, the driver, intervene. Service brake hold is
only available on vehicles equipped with Active Cruise with Braking (ACB) Stop and
Auto-Go™. Service brake hold is not a parking brake and you must intervene and
secure the vehicle. You, the driver, should manually set the parking brakes when
exiting the vehicle.
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.
NOTE: An active HDB event can be overridden by the driver by steering, applying
full throttle, or applying the service brake. Additionally, the HDB feature can be
suppressed by activating the turn signal or hazard lights when making a lane change.
NOTE: HDW and HDB can only be activated if the lane markings are identifiable by
the system.
NOTE: When making lane changes, the proper use of the turn
signals and/or hazard lights ensures the Bendix Fusion system
Lane Departure Warning (LDW), HDW, and HDB technologies
are aware of your intention to depart a lane and will suppress
alerts and braking. The vehicle is equipped with a 15-minute
LDW, HDW, and HDB disable switch (Figure 19) that you can
activate when driving on roads with inconsistent lane markings
that can cause excessive LDW, false warnings. Examples of these Figure 19 – LDW,
circumstances include construction zones, HDW, and HDB poorly HDW, and HDB
marked lanes, or missing lane markings. The LDW, HDW, and HDB Disable Switch
alerts will automatically become available again after 15 minutes
or if the disable switch is pressed a second time.
When HDW and HDB are activated excessively, the Bendix Fusion system provides
a warning and will disable these features until you restart the vehicle. Other Fusion
system features, including LDW, will remain available.
NOTE: The service brake hold can be canceled if you press the accelerator pedal or
the brake pedal, or apply the parking brake.

Overspeed Alert and Action (OAA)
The Bendix® Fusion™ system can read most roadside speed limit signs in the United
States and Canada and may potentially warn you if your vehicle speed exceeds the
posted speed limit.

The Overspeed Alert and Action (OAA) may potentially sound an audible and visual
alert 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 may potentially experience a haptic warning through a brief engine
torque reduction of about one (1) second.
Both the +5 (8 kph) and +10 mph (16 kph) 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.
Figure 21 shows a message you may see on the integrated
display when the OAA is activated.
NOTE: Dash display images are representative only and
may not reflect the actual vehicle display.
NOTE: The OAA feature does not apply vehicle brakes.

Figure 21 – OAA

SPECIAL ALERTS
Brake Overuse Alert
The Bendix® Fusion™ system may potentially provide a warning when it is intervening
and using the service brakes excessively. Overuse of the service brakes can lead to the
brakes overheating which may result in a reduction or loss of braking performance.
This scenario is typically referred to as brake fade. Using cruise control on downhill
stretches of road may cause this alert to activate. When the system detects brake
overuse, a message may be shown on the display along with an audible alert. As the
driver, you should intervene immediately.
NOTE: Dash display images are representative only and may not reflect the actual
vehicle 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 Bendix Fusion
system interventions will be limited to de-throttling and engine retarder only. The
system will automatically disable all the Fusion system service 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 Bendix Fusion system interventions (dethrottling, engine retarder, or brake applications) will be disabled until the next
ignition cycle.
NOTE: In all cases, you have the ability to apply the service brakes if necessary. You
should take care since overheated brakes may reduce the vehicle’s braking capability.
Overheated brakes could be an indicator of a malfunctioning system or service brake
and should be checked by a certified technician immediately.
NOTE: In all cases, as the driver, it is your responsibility to maintain safe operation
of your vehicle. This includes proper gear and speed selection, and engine retarder
activation, especially when driving routes with extended downhill sections of
roadway.

21

Power-on Self-test (POST)
During every power-on cycle, the Bendix® Fusion™ system executes a Power-on Selftest (POST) during which the driver assistance features described in this document are
not available. Vehicle cruise control is still available to the driver during the POST. The
POST requires the vehicle speed to be above 5 mph (8 kph) and for the radar sensor
to see objects to validate proper radar sensor operation. Under normal operating
conditions, the POST completes within a few seconds and all driver assistance features
become available to you.
In the special case where the radar sensor 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
DTC, but regular vehicle cruise control will remain available to you.

SYSTEM RESPONSES
This chart illustrates how the system may react to specific driver actions.
If you, the driver, do this:

The Bendix Fusion system may 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. The Bendix Fusion system will honor the greater
braking power demand from either the driver or the system.

Step aggressively on the
accelerator (during a
collision mitigation event).

As the driver, you are always in control. Your actions can override any
Bendix Fusion system actions.

Step on the brake (when
cruise control is on and set).

Cruise control will be canceled.

Step on the brake or
accelerator pedal, or
activate the parking brake
(when in service brake
hold).

Service brake hold will be canceled. You, the driver, must intervene
and secure the vehicle by pressing the accelerator pedal, brake
pedal, or parking brake as appropriate.

Step on the accelerator
(when cruise control is on
and set).

Cruise control will be overridden until the accelerator is released;
then cruise control will resume the original set speed automatically.

Once an Autonomous Emergency Braking (AEB) event has started, you,
the driver, can override its activation by applying a significant change
in accelerator 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.

22

Your Action:

Potential Reaction of the Bendix® Fusion™ System:

If you, the driver, do this:

The Bendix Fusion system may do this:

Switch on the cruise
control.

Nothing. The Active Cruise with Braking (ACB) 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, if needed. 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.

Block the radar sensor.

The Bendix Fusion system performance will be diminished, or
disabled, when the radar sensor becomes physically blocked. When
the radar sensor can detect this condition, an alert may be issued to
warn you.
You should visually inspect the radar sensor and mounting bracket
regularly and remove any mud, snow, ice build-up, or other
obstructions. After clearing any obstructions, you will need to turn
the vehicle off and then on to clear applicable Diagnostic Trouble
Code (DTC).

Block the camera.

The Bendix Fusion system performance will be diminished, or
disabled, whenever the camera becomes blocked. An alert may be
issued to alert you of this condition.
When a camera blockage is detected, it will be indicated through an
alert and will disable all camera-based features (i.e. Lane Departure
Warning, Highway Departure Braking/Warning, OverSpeed Alert
and Action, and Stationary Vehicle Braking).

Use normal cruise control
“+/-” switch.

Vehicle speed will be increased (+) or decreased (-) 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 indicators/alerts above are typical, but may vary from the
descriptions shown here by vehicle manufacturer.
