Oncoming Traffic
The Bendix Fusion system may deactivate the high beam headlights when it
detects the headlights of another vehicle. If it detects an oncoming vehicle –
with either one (1) or two (2) headlights – the high beam headlights may be
deactivated. If the vehicle is no longer visible (usually because it has passed
the driver’s vehicle) and no turn-off conditions exist (see above), the high beam
headlights may be reactivated after a delay.
Preceding Traffic
If the system detects a vehicle in front – with either one (1) or two (2) taillights –
the high beam headlights may be deactivated. If the vehicle is no longer visible
and no turn-off conditions exist (see above), the high beam headlights may be
reactivated after a delay.

High Beam Assist (HBA) Limitations
NOTE: High Beam Assist (HBA) is not a substitute for the driver’s judgement of
when to activate or deactivate the high beam headlights. Therefore, the driver
must always monitor the situation and intervene by switching the high beam
headlights manually – if necessary – to avoid annoyance or risk for any traffic
participant.
HBA may not function as expected in the following situations, and driver
intervention may be necessary:
•

In severe weather conditions (e.g., dense fog or heavy precipitation)

•

In the presence of poorly lit traffic participants (e.g., pedestrians)

•

In tight curves, at hilltops, or in depression intersections

•

In poorly lit built-up areas, in the presence of highly reflective signs, or other
unusual lighting conditions

•

When the windshield in front of the camera is fogged, dirty, or otherwise
obscured

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. When the system Figure 26 – Brake Overuse
detects brake overuse, a message may be
shown on the display. Figure 26 shows a message you may see on the integrated
display when the Brake Overuse Alert is activated. As the driver, you should
intervene immediately. Please verify with the vehicle OEM for visual indications
your vehicle may display.
If the Fusion system does not detect a driver intervention, it will shut itself off
and set a DTC. All Fusion Active Cruise with Braking (ACB) system interventions
(de-throttling, engine retarder, or brake applications) will be disabled until the
next ignition cycle or until the DTC clears.
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, it is the driver’s responsibility to maintain safe operation
of their vehicle. This includes proper gear and speed selection, and engine
retarder activation, especially when driving routes with extended downhill
sections of roadway.

SYSTEM RESPONSES
This chart illustrates how the system reacts to specific driver actions.
Your Action:

Potential Reaction of the Bendix® Fusion™ System:

If you, the driver, do this:

The Fusion system may do this:

Step on the brake
You, the driver, are always in control and are able to apply full
(during an Autonomous
braking power. The Bendix Fusion system will honor the greater
Emergency Braking [AEB] braking power demand from either the driver or the system.
event).
Step aggressively on the
accelerator (during an
AEB event).

You, the driver, are always in control. As the driver, your actions
can override any Fusion system actions.

Step on the brake (when
Active Cruise with
Braking [ACB] is on and
set).

ACB 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 by pressing the accelerator pedal, brake pedal, or
parking brake as appropriate.

Step on the accelerator
(when ACB is on and set).

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

Switch on ACB.

Nothing. The ACB (Active Cruise with Braking) feature will not
engage until you, the driver, set the ACB speed.

Switch off ACB.

The ACB feature will turn off; the AEB feature remains active
and ready to intervene, if needed. You, the driver, will continue
to hear all alerts as needed.

Set the ACB speed.

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

Once an AEB event has started, you, the driver, can override
its activation by applying a significant change in accelerator or
steering 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.

Your Action:

Potential Reaction of the Bendix® Fusion™ System:

If you, the driver, do this:

The Fusion system may do this:

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 functions (e.g., Following Distance Alerts, Active
Cruise with Braking, Autonomous Emergency Braking, Lane
Departure Warning, Highway Departure Braking/Warning, and
Overspeed Alert and Action).

Use normal Active Cruise
with Braking (ACB) “+/-”
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
Typical System
Indications and
Alerts

Situation

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 help mitigate 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 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.
