The ACB feature is automatically activated, and your vehicle
maintains set speed and following distance behind the vehicle
ahead.

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 may be issued to warn you, the driver,
of this condition.
You, the driver, should visually inspect the radar and mounting
bracket regularly and remove any mud, snow, ice build-up, or other
obstructions. After clearing any obstructions, you, the driver, may
need to turn the vehicle off and then on to clear the fault code.

Block the camera.

The Fusion system performance will be diminished, or disabled,
whenever the camera becomes blocked. An alert may be issued to
alert you, the driver, of this condition.
A blocked camera will be indicated through an alert and will disable
all camera-based functions (e.g., Following Distance Alerts, Active
Cruise with Braking, Lane Departure Warning, Highway Departure
Braking/Warning, Overspeed Alert, and Autonomous Emergency
Braking which includes Stationary Vehicle Braking [SVB]).

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 detected and within the set
following distance.

NOTE: The system indicators/alerts above are typical, but may vary from the descriptions
shown here by vehicle manufacturer.

WHAT TO EXPECT
The following charts illustrate what to expect from the Bendix® Fusion™ system in
various driving situations you may encounter. Both the system indication, as well as
action(s) to expect from the system, are illustrated on the pages that follow.
What to Expect
Situation

Typical System
Indications and Alerts

Typical System
and/or Driver Actions

Stationary vehicles ahead in your lane of travel
A stationary forward
vehicle is detected
ahead in your lane.
Cruise is either “ON” or
“OFF.”

An Impact Alert (IA) may
potentially be issued if the
Fusion system determines a
detected stationary vehicle is a
potential collision threat.

You, the driver, must immediately act
to potentially avoid – or lessen the
severity of – a collision.
If a collision is likely to occur, the
Fusion system may potentially provide
a warning and/or apply the vehicle
brakes.

Moving vehicles ahead in your lane of travel
Your vehicle comes up
fast behind a slowermoving detected
forward vehicle or
the detected forward
vehicle slows rapidly.
Cruise is either “ON” or
“OFF.”

The Following Distance Alert
(FDA) may potentially sound,
and a visual message/icon
may potentially appear on the
display.
Depending on how close your
vehicle approaches, the system
may initiate an Impact Alert (IA)
warning.

You, the driver, must respond as
needed.
If a collision is likely to occur, the
Autonomous Emergency Braking
(AEB) feature may potentially apply
your vehicle’s service brakes.

NOTE: The system indicators/alerts above are typical, but may vary from the descriptions
shown here by vehicle manufacturer.

Moving vehicles ahead in your lane of travel
Another vehicle crosses
the road perpendicular
to your path of
travel – such as at an
intersection.

None.

No system action.
You, the driver, must respond as
needed.

Cruise is either “ON” or
“OFF.”

An Autonomous
Emergency Braking
(AEB) event has begun
and if you, the driver,
steer into an adjacent
lane to avoid the
forward vehicle.

If the system detects the
adjacent lane is blocked by
a potentially threatening
situation, the Impact Alert
(IA) warning and braking may
continue.

The Bendix® Fusion™ system may
continue to alert and apply the brakes
if it detects another vehicle ahead in
the new traffic lane posing a threat of
collision.

Cruise is either “ON” or
“OFF.”
Lane Departures
You, the driver, activate
the right or left turn
signal, then merge into
the corresponding lane.
Cruise is either “ON” or
“OFF.”

No Lane Departure Warning
(LDW), Highway Departure
Warning (HDW), or Highway
Departure Braking (HDB)
alerts or braking would occur.
However, other Autonomous
Emergency Braking-related
(AEB) functions would operate
as intended.

No system action.

audible vibration/visual alert
may potentially activate.

You, the driver, must respond as
needed.

A simulated “rumble strip”
audible vibration/visual alert
may activate when the right
side of the vehicle crosses the

continues to depart the lane
across the fog line, and an
additional audible alert may
be sounded.

You, the driver, must respond as
needed.

You, the driver, must respond as

(Use the turn signal when changing
lanes and/or keep your vehicle within
the lane markings.)

Cruise is either “ON” or
“OFF.”

Traveling above
approximately
37 mph / 60 kph, your
vehicle crosses the solid
line on the side of the
roadway. The vehicle
continues to depart the
lane with approximately
the center (or more) of
the vehicle crossing the
solid line on the side of
the roadway.

If you, the driver, do not act to correct
the vehicle path into the proper lane
position, the alert may continue and
the Bendix Fusion system may apply
the brakes to assist you, the driver, in
reducing the vehicle speed.

32

Due to the inherent limitations of radar and camera technology as well as
the vast number of traffic scenarios possible, the enhanced Autonomous
Emergency Braking (AEB) technology may not:
• react to moving or stationary vehicles, pedestrians, or cyclists in your
vehicle’s lane of travel.
• sound alerts, warnings, or brake interventions when expected.
Additionally, alerts, warnings, or brake interventions may occur when not
expected.

POTENTIALLY CHALLENGING SITUATIONS FOR
THE BENDIX® FUSION™ SYSTEM
The following examples illustrate situations in which the Bendix® Fusion™ system
may potentially 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. For further information on challenging scenarios, refer to BW8107,
Challenging Scenarios, on B2Bendix.com.
Driver Assistance Systems (DAS), such as the family of Bendix Fusion active safety
solutions, help to continuously monitor a variety of vehicle parameters and sensors
to determine if the vehicle is near a collision or a following distance threshold. As
a reminder, all Driver Assistance Systems have limitations and may misinterpret a
scenario leading to a reaction when one is not anticipated or when one may not be
required. This section describes driving scenarios that may be challenging for any
Bendix safety system.

KEY SYSTEM FUNCTIONALITY CLARIFICATIONS
High speed differences between your truck and the detected forward vehicle
may potentially result in little to no system alert or activation.
Radars work based on reflections from metallic objects which can overlap,
cancel, or interfere, causing the radar sensor to miss targets or see false targets.
Low light or low roadway-background contrast conditions can impact the
camera’s ability to recognize the forward vehicle and limit system braking
