Lane Departure
Warning (LDW)

Stationary Vehicle Braking (SVB) – When a
large, stationary, metallic object in a vehicle’s
lane of travel is definitively identified as a vehicle,
you will be notified up to 3.5 seconds before
impact. If you do not take action to address
the potential impact that caused the alert,
Wingman Fusion can automatically engage the
brakes to assist you in reducing the severity
of or potentially avoiding a collision with that
stationary vehicle.
If the system cannot definitively identify the
stationary object as a vehicle – for example, if
the vehicle is not a licensed motorized vehicle,
or certain types of trailers – the driver will get up
to 3.0 seconds of alert to address the situation
ahead, but no automatic braking will be applied.
Stationary Vehicle Braking is most useful when
approaching a line of stopped traffic or a stalled
vehicle that is not immediately recognized by the
driver. Without the automatic alert and braking,
it may be too late to avoid impact.

Lane Depar ture Warning (LDW ) – The
Bendix® Wingman® Fusion™ system has the
ability to warn you if the vehicle is not tracking
in the intended roadway path. In most vehicle
applications the LDW system is enabled above
37 mph / 60 kph. You should immediately correct
the vehicle tracking and maintain the correct
position in the lane.

Over Speed
Limit

Overspeed Alert (OA) – The Bendix®
Wingman® Fusion™ system has the ability
to warn you if the vehicle’s speed exceeds
the posted legal limits. The Overspeed
Alert is enabled when the vehicle is
traveling greater than 5  mph / 8 kph
from the posted limit. The driver should
immediately reduce the vehicle’s speed
to the posted legal limit. Note that the
system does not activate overspeed
alerts where the posted speed limit is
20 mph / 32 kph or less.

International travel: When changing between regions which post speeds in
miles and those which post in kilometers, the speed limit sign recognition feature
will not function until the correct US/Metric selection has been made.

Special Alerts
Brake Overuse Warning – The Bendix® Wingman®
Fusion™ system provides a warning when the
system uses the foundation brakes excessively.
Overuse of the foundation brakes can lead to
the brakes overheating and a potential loss of
braking performance caused by brake fade.

ACB BRAKING OVERUSE
Press OK for Menu

Approach grades as you would normally, with the appropriate gear
selected and at a safe speed. Cruise control should NOT be used on
downhill grades.
You should use appropriate gearing and brake techniques on downhill
grades. When the system detects brake overuse, depending on the
vehicle manufacturer, a text message will be displayed on the dashboard
and an audible alert will be activated.
•

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 – will discontinue the alert. Following an overuse
alert, you should not reset cruise control for at least 20 minutes. This
gives the brakes time to cool down. If you choose to reset cruise
control during that 20 minute period, Wingman Fusion interventions
will be limited to de-throttling and engine retarder only. The system
will automatically disable all Wingman Fusion system foundation
brake applications for at least 20 minutes.

28

•

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 Wingman Fusion interventions
(de-throttling, engine retarder or brake applications) will be disabled
until the next ignition cycle.

NOTE: In all cases, you still have the ability to apply the foundation brakes
if necessary. You should take care since overheated brakes may reduce
the vehicle’s braking capability.

Bendix® Wingman® Fusion™ Diagnostic Trouble Codes
The Bendix® Wingman® Fusion™ system is monitored and if any malfunction
is detected, a Diagnostic Trouble Code (DTC) will be set and you will be
alerted. The exact alert given depends on the vehicle manufacturer: refer
to your vehicle operator’s manual and the Bendix® Wingman Fusion Service
Data sheet SD‑61‑4962, the Bendix™ AutoVue® FLC-20™ Camera Service Data
sheet SD-64-20124, or the SafetyDirect® by Bendix CVS Processor Service
Data sheet SD-65-21025 for more information.

Potential False Alerts
The Wingman Fusion system should have significantly fewer false alerts than
earlier systems. Radar and camera technology is not perfect, and false alerts
sometimes occur. Radar misalignment will likely lead to increases in stationary
object false alerts. In the case of speed sign alerts, some road signs may
potentially not be able to be recognized – or be recognized incorrectly – by
the system.
Drivers should take into account the road conditions, and any other factors
they are encountering, as they choose how to react to any alerts they receive
from the Bendix Wingman Fusion system.

29

When Not to Use Cruise Control
The Active Cruise with Braking feature in the Bendix® Wingman® Fusion™
system is automatically ready when normal cruise control is set.
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®
Wingman® Fusion™ system.
Dense Traffic – Do not use cruise control in heavy traffic.
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 – Do not use cruise control when
entering or exiting roadways.
Downhill Grades – Do not use cruise control on downhill
grades.
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.
Visit bendix.com for more information and for any updates to
these limitations and restrictions.

Additional Operational Notes
Adjusting the Alert Volume
The Bendix Wingman ® Fusion™ system audible alerts are pre-set at the
factory for fully integrated systems and cannot be turned off by the driver,
but, depending on the OE, the volume may adjustable.
®

For systems using a Bendix® Driver Interface Unit (DIU™) display, see Bendix
Wingman Fusion Service Data sheet SD-61-4962 for information about volume
adjustment.

Temporarily Disable the Lane Departure Warning (LDW)
To avoid erroneous LDW warnings in areas such as construction zones – where
the non-standard or overlapping road markings present might cause false
alerts – the Wingman Fusion system has an enable/disable switch. Each OEM
typically has a different arrangement to allow the driver to temporarily disable
the Lane Departure Warning (LDW) system and to display the system status.
Refer to the OEM Operator’s Manual for any system indicator lamp(s). See

Event Capture
In the case of vehicles configured to do so, the enable/disable switch used
by the LDW system also functions – when depressed for six (6) seconds – to
activate a request from the SafetyDirect® by Bendix CVS Processor to the
On Board Computer (OBC)/Telematics system to transmit ten seconds of
video data ­– the five (5) seconds before, and five (5) after the button was
pressed). In some cases, more video data may be available using the Bendix
SafetyDirect Client.
31

Passing a Vehicle/Changing Lanes
With cruise control set, if you decide to change lanes or pass a vehicle by
applying the throttle, the vehicle being passed will no longer be detected
by the radar and camera.

When No Other Vehicles are Present
When no forward vehicle is within range of the radar or camera, your vehicle
will maintain its set speed just like ordinary cruise control.

Radar-Reflective Stationary Vehicles & Objects
You should be attentive to stopped vehicles and objects on the roadway.
The Bendix® Wingman® Fusion™ system will give up to three (3) seconds
alert when you approach a detected, sizable, stationary object with
metallic (radar-reflective) surfaces in your lane of travel. When a large,
stationary, metallic object in a vehicle’s lane of travel is definitively
identified as a vehicle, the driver is notified up to 3.5 seconds before
impact.
Metallic Objects May Impair the Radar – Objects that are radar-reflective
– such as crash barriers, guard rails, construction zone barricades, and
tunnel entrances – may impair the function of the radar.
Vehicles May Not be Recognized
If the system cannot definitively identify the stationary object as a vehicle
– for example, if the vehicle is not a licensed motorized vehicle, or certain
types of trailers – the driver will get up to 3.0 seconds of alert to address
the situation ahead; no automatic braking will be applied.

Pedestrians, Animals, Non-Metallic
and Limited-Metallic Objects
Pedestrians, Animals, Non-metallic or Limited-metallic Objects – The
Bendix Wingman Fusion system will not warn or react to pedestrians,
animals, and non-metallic objects. The Wingman Fusion system may
not warn or react to limited-metallic objects (such as recreational
vehicles, horse-drawn buggies, motorcycles, logging trailers, etc.).

32

Tracking Vehicles in a Curve
With cruise control set, when following a detected forward vehicle around
a curve, the forward vehicle may be lost by the Bendix® Wingman® Fusion™
system. The Active Cruise with Braking feature will delay acceleration back
to the set speed until it regains contact with the vehicle ahead, or detects
that there is no longer a vehicle ahead, or after a time gap (based on the last
following distance recorded).
For 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 Wingman Fusion system will delay the vehicle
acceleration back to 50 mph / 80 kph for 3 seconds.
You should be especially attentive to the Wingman Fusion system behavior
through curves. In some cases, when traveling around a curve, the Fusion
system may lose the vehicle ahead and attempt to accelerate when
resuming the set speed.
It is also possible for the Wingman Fusion system to begin tracking vehicles
in other lanes when traveling around curves. In cases where the Wingman
Fusion system perceives that an adjacent-lane vehicle is in your lane, the
system may intervene and begin making brake applications.

Applying the Brakes Before the System Does
If you determine that a hazard or unsafe condition exists, you should take all
necessary actions immediately. Never wait for the Wingman Fusion system
to intervene.
Safe operation and control of the vehicle is the responsibility of the
driver at all times. If you, the driver, apply the brakes, cruise control will
disengage automatically, and no Wingman Fusion intervention will occur.

Approaching Slower-Moving Vehicles
When approaching a slower-moving vehicle ahead, the driver should anticipate
this and begin applying the vehicle’s brakes early. Do not wait for the Bendix
Wingman Fusion system to intervene.

33

Vehicles Crossing Your Path or Coming Towards You
The Bendix® Wingman® Fusion™ system reacts ONLY to vehicles that
are stationary, or moving in the same direction as your vehicle. The
Wingman 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.

Stability System Performance
System Maintenance and Troubleshooting
Importance of Foundation Brake Maintenance – Optimal Wingman
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 that the
vehicle be equipped with properly sized and inflated tires, with a safe
tread depth.
Importance of ABS Maintenance – Optimal Wingman Fusion system
braking requires a properly maintained ABS (Antilock Brake System)
system. Have any ABS Diagnostic Trouble Codes (DTCs) corrected by a
qualified technician at the earliest opportunity.

34

Preventive Maintenance:
®

®

The Bendix Wingman Fusion™ system is not maintenance free. The key
items to keep the system functioning properly include:
1.

Keep the radar and camera lens clean and free of obstructions.

2.

Visually inspect for any damage to the bumper or the Wingman Fusion
cover, bracket, or radar to ensure that the alignment has not been
compromised. Never use the radar unit as a step.

3.

Periodically check the radar alignment.

4.

Perform appropriate inspections of the braking system as required by
the manufacturer to ensure brakes are in proper working order.

5.

Ensure that the tires are properly inflated and that adequate tread is
present.

When the Bendix Wingman Fusion System Isn’t Working:
If the Bendix Wingman Fusion system has detected a problem, depending
on the vehicle manufacturer, there will typically be a warning message on
the dashboard display and a Diagnostic Trouble Code (DTC) will be set.
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 Wingman Fusion system), or if all cruise control functions
need to be disabled until servicing is carried out. The system should be
serviced as soon as possible to restore full functionality.

Frequently Asked Questions
1.

Are automatic foundation brake interventions always ready to
intervene?
Yes, when the vehicle is moving above 15 mph / 24 kph. The Bendix®
Wingman® Fusion™ system will alert the driver and activate the foundation
brakes when a collision with a detected forward vehicle is likely. The
Fusion system does not replace the need for the driver to remain alert,
react appropriately and in a timely manner, and use safe driving practices.

2.

Are the six driver alerts always available?
Yes, but only above their minimum activation speeds. All six driver alerts
(Impact Alert, Following Distance Alert, Stationary Object Alert, Stationary
Vehicle Braking, Lane Departure Warning, and Overspeed Alert) are always
ready to alert the driver regardless of whether or not cruise control is
operating — unless a DTC is set.

3.

How can I tell the difference between the alerts?
Any audible and/or visual alert by the system means that your vehicle
is too close to the vehicle ahead, your vehicle is outside the intended
lane of travel, or your vehicle is overspeeding the posted speed limit.
You must immediately act to potentially avoid, or lessen the severity
of a collision and to maintain regulated control of the vehicle to the
intended lane and speed limit.
A solid tone means you should actively apply the brakes because the
Bendix® Wingman® Fusion™ braking capability is not enough to ensure
a safe following distance. The alerts are audibly different, assisting
the driver to pay full attention to the road, not the dash.

4. Does the Wingman Fusion system detect stationary vehicles and/or
stationary objects?
Yes. In cases where the system recognizes a stationary vehicle ahead, the
alert is up to three-and-a-half (3.5) seconds. The system will also give up to
three (3) seconds alert when approaching a detected, sizeable, stationary
object with metallic (radar-reflective) surfaces in your lane of travel.
Braking or throttle intervention will only occur in response to stationary
objects that are definitively identified as a motor vehicle, i.e. those which
have easily recognized vehicle characteristics.
5.

Can I use an aftermarket “deer guard” on my truck?
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. See Bendix Technical Bulletin TCH-061-003.
