“OFF.”

A stationary vehicle alert
may potentially be issued
if the Bendix Fusion system
determines a stationary
detected forward vehicle is a
potential collision threat.

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

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

Indications and Alerts

Situation

Typical System
and/or Driver Actions

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

The detected forward
vehicle slows rapidly.
Cruise is either “ON” or
“OFF.”

Another vehicle crosses
the road perpendicular
to your path of
travel – such as at an
intersection.

The Following Distance Alert
(FDA) may potentially sound,
and a visual message/icon
may potentially appear on the
display.

You must respond as needed. If a
potential collision is likely to occur, the
collision mitigation feature may apply
your vehicle’s service brakes.

Depending on how close your
vehicle approaches, the system
may initiate an Impact Alert (IA)
warning.

The FDA and IA warning
(continuous tone) may
potentially sound, and a
visual message/icon typically
appears on the display.

You must respond as needed.

None.

None.

If a potential collision is likely to occur,
the collision mitigation feature may
apply your vehicle’s brakes.

You must respond as needed.

Cruise is either “ON” or
“OFF.”

A collision mitigation
braking event has begun
and you, as the driver,
steer into an adjacent
lane to avoid the
forward vehicle.

If the system detects the
adjacent lane is blocked by a
potential collision threat, the
IA warning may potentially
sound and a visual message/
icon typically appears on the
display.

The Bendix® Fusion™ system may
potentially continue to apply the
brakes and/or alerts if it detects
another situation ahead in the new
traffic lane posing a potential collision.

Cruise is either “ON” or
“OFF.”

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

None.

A “rumble strip” audible/
vibration/visual alert may
potentially activate.

You must respond as needed. If you
do not respond, the Bendix® Fusion™
system may potentially apply the
brakes if the fog line is crossed to
reduce the vehicle speed to alert you.

You must respond as needed.

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

Situation

Typical System
Indications and Alerts

Typical System
and/or Driver Actions

Overspeed Alert and Action (OAA)
Your vehicle passes a
U.S. or Canadian speed
limit sign and you are
not speeding.

The OEM-integrated display
may potentially show the
posted speed limit.

None.

In some cases, the
Overspeed Alert and
Action (OAA) feature
may detect speed
signs on parallel roads,
warning you, the driver,
and reducing the
accelerator pedal input.

A possible alert will sound.

The system may respond with a
possible de-throttle.

Your vehicle passes
a speed limit sign
and your vehicle is
exceeding the speed
limit by 5 to 9 mph
(8 to 14 kph).

An Overspeed Alert and
Action (OAA) may potentially
be issued and the posted
speed limit will be visually
presented to you, the driver.

None.

Your vehicle passes a
speed limit sign and
is traveling >10mph
(16 kph) over the posted
speed limit.

An OAA may potentially be
issued and the posted speed
limit will be visually presented
to inform you that your vehicle
should slow down.

A one-second accelerator pedal
decrease of the engine may
potentially occur.

Cruise is either “ON” or
“OFF.”

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

None.

None.

With a detected forward
vehicle.

The cruise control ON indicator
is illuminated and the detected
forward vehicle icon is
illuminated.

The Active Cruise with Braking (ACB)
feature will maintain the set speed

The Following Distance Alert
(FDA) may potentially sound,
and a visual message or icon
typically appears on the display.

You must respond as needed.

The FDA may sound, and a
visual message or icon typically
appears on the display.

The system may intervene to bring
the vehicle to a full stop. You, the
driver, can resume cruise control by
pressing down on the throttle or by
pressing the resume button within
a few seconds and the vehicle will
accelerate back to the cruise control
set speed.

Cruise is “ON” and speed
is “SET.”

The detected
forward vehicle slows
moderately.
Cruise is “ON” and speed
is “SET.”

The detected
forward vehicle slows
moderately to a full stop.
Cruise is “ON” and speed
is “SET.”

If the system intervenes, it may
derate the engine, the engine
retarder may be engaged, and the
service brakes may be applied, in
that order. If your vehicle speed falls
below the minimum defined speed,
the vehicle will cancel cruise control
and will not attempt to increase the
vehicle speed to the previously set
cruise control speed.

Situation

Typical System
Indications and Alerts

Typical System
and/or Driver Actions

Interactions with detected forward vehicles in your lane of travel
The detected forward
vehicle slows rapidly.
Cruise is “ON” and speed
is “SET.”

A detected forward
vehicle traveling at a
higher rate of speed cuts
in front of your vehicle
and speeds away.

The Impact Alert (IA) warning
(continuous tone), may
potentially sound and a visual
message/icon typically appears
on the display. The Following
Distance Alert (FDA) may also
be heard.

You must respond as needed.

FDAs may be given, depending
on the exact system
configuration that has been set
for the vehicle, and how close
the vehicle cuts in front.

Vehicle maintains set speed and

If the system intervenes, the vehicle
accelerator pedal input may be
reduced; the engine retarder may be
engaged; and the service brakes may
be applied, in that order.

Cruise is “ON” and speed

Downhill Grades
Going down a grade
with a detected forward
vehicle.

DO NOT USE cruise control on
downhill grades.

DO NOT USE cruise control on
downhill grades. Brake overuse may
occur.

Cruise control should NOT be used on downhill grades. See the CDL manual
instructions on proper gear usage for downhill grades.

NOTE: The system indicators/alerts above are typical, but may vary from the
descriptions shown here by vehicle manufacturer.
NOTE: The preceding sections show examples of situations and typical Bendix® Fusion™
system responses. However, the charts do not attempt to cover all possible situations.
Due to the inherent limitations of radar sensor and camera technology as
well as the vast number of traffic scenarios possible, the enhanced collision
mitigation technology may not:
• react to moving vehicles 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 potential 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.
