Important Safety Information About
Bendix® Wingman® Advanced™
SECTION 1: GENERAL
The driver is always responsible for the control and safe operation
of the vehicle at all times. The Bendix® Wingman® Advanced™
system does not replace the need for a skilled, alert professional
driver, reacting appropriately and in a timely manner, and using
safe driving practices.
Use cruise control only in the conditions that are normally
recommended for its use. Setting the cruise control will also set the
adaptive cruise control with braking feature of the Bendix Wingman
Advanced system. It must never be used on roads where you can
not drive safely at a steady speed, including city streets, winding
roads and sharp curves, downhill grades, poor road conditions (such
as gravel or dirt), ice or wet surfaces (wet surfaces may increase the
risk of hydroplaning), or in fog, heavy rain or snowy conditions.
Also, the cruise control should not be used in inclement weather, in
dense traffic, or where smaller vehicles–such as motorcycles–are
ahead in the same lane.
Always switch off the cruise control (by stepping on the brakes or
turning off the cruise control switch) when entering turning lanes,
entering or exiting highways, driving through construction zones, or
similar situations. See page 22 for more details.
Variations from this Manual – Vehicle manufacturers, and some
previous models of the Bendix Wingman Advanced system, may
use alerts, messages, and dash arrangements that vary from the
examples shown here. Consult the vehicle operator’s manual(s) for
applicable details regarding use and operation.
3
The Bendix® Wingman® Advanced™ system reacts ONLY to vehicles
moving in the same direction as your vehicle. The Wingman
Advanced 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.
Vehicle Equipped with Bendix®
Wingman® Advanced™
Detected Forward Vehicle
RADAR
System does not brake nor
warn for vehicles approaching
from the side or oncoming
When the Wingman Advanced system needs to intervene, it works
in conjunction with the Bendix® ESP® electronic stability system to
engage the brakes. The system should never be relied upon to
stop your vehicle or to avoid a collision. The driver can, and should,
still apply full braking force, if needed.
SECTION 2: DRIVER ALERTS & WARNINGS
Driver Alerts and Warnings – Before driving with Wingman
Advanced, the driver should fully understand all the audible alerts
and visual indicators that the system provides. This booklet will assist
in explaining what each of them means. Any audible and/or visual
alert by the system means that your vehicle is too close to the
vehicle ahead. The driver must immediately act to potentially
avoid, or lessen the severity of, a collision.
The Impact Alert (IA) is the most severe alert issued by the
Wingman Advanced system. This alert indicates that a collision
with the detected forward vehicle is likely. The driver must
immediately act to potentially avoid, or lessen the severity of, a
collision. The Impact Alert is ready to alert the driver whenever the
vehicle is moving above 15 mph.
When activated, the IA will sound and a visual message/icon
typically appears on the dash screen or Bendix® Driver Interface Unit
(DIU) display. The actual sound/display method varies by vehicle
manufacturer.
4
The Following Distance Alert (FDA) provides both audible and
visual alerts whenever the time between your vehicle and the
vehicle ahead is less than one and a half (1.5) seconds* and
getting closer. Once the audible alert is given, the driver should
increase the distance between his/her vehicle and the vehicle
ahead until the audible alert stops. The FDA is ready to alert the
driver whenever the vehicle is moving above five (5) mph. If the
following distance continues to decrease, the driver will hear more
rapid audible alerts. When the FDA reaches its highest level, typically
a red LED also illuminates on the instrument cluster. The FDA may
be accompanied by a visual alert.
* 1.5 seconds is the system default and may vary by fleet/OEM.
Stationary Object Alert (SOA) – The Bendix® Wingman® Advanced™
system will give up to a three (3) second alert when approaching a
detected, sizable, stationary object with metallic (radar-reflective)
surfaces in your lane of travel. This alert indicates that a collision
with a stationary object is likely. The driver must immediately
act to potentially avoid, or lessen the severity of, a collision. The
SOA is ready to alert the driver whenever the vehicle is moving above
ten (10) mph.
Due to the inherent limitations of radar technology, the Stationary
Object Alert System may alert in response to stationary objects
not in the vehicle lane of travel. These objects may include
bridges, signs, parked vehicles and traffic lights. Braking or
throttle intervention will not occur in response to stationary
objects. The driver remains responsible for safely controlling the
vehicle at all times by appropriately applying the brakes, steering
or throttle as needed.
The driver should be especially careful when approaching certain
types of vehicles and objects. The Wingman Advanced radar may
not be able to detect objects with limited metal surfaces (such as
recreational vehicles, horse-drawn buggies, motorcycles, logging
trailers, etc). NOTE: Entering a curve may reduce the alert time to
less than three (3) seconds.
Pedestrians, Animals, Non-metallic or Limited-metallic Objects –
The Wingman Advanced system will not warn or react to
pedestrians, animals, and non-metallic objects. The system may
not warn or react to limited-metallic objects (such as recreational
vehicles, horse-drawn buggies, motorcycles, logging trailers, etc).
Metallic Objects May Impair the Radar – Objects that are radarreflective–such as crash barriers, guard rails, construction zone
barricades, and tunnel entrances–may impair the function of the
radar.
5
Brake Overuse Alert - The Bendix® Wingman® Advanced™ system
provides a warning when the system is intervening and using
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. Using cruise control
on downhill runs will cause this alert to be activated.
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.
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. The driver should intervene
immediately.
•
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, the driver should not reset cruise control for at least 20 minutes.
This gives the brakes time to cool down. If the driver chooses to
reset cruise control during that 20 minute period, Wingman Advanced
interventions will be limited to de-throttling and engine retarder only.
The system will automatically disable all Wingman Advanced system
foundation 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). The driver will continue to receive
alerts, but ALL Wingman Advanced interventions (de-throttling,
engine retarder or brake applications) will be disabled until the next
ignition cycle.
Note: In all cases, the driver still has the ability to apply the foundation
brakes if necessary. The driver should take care since overheated
brakes may reduce the vehicle’s braking capability.
6
SECTION 3: EQUIPMENT MAINTENANCE
Importance of Antilock Braking System (ABS) Maintenance –
Optimal Bendix® Wingman® Advanced™ system braking requires a
properly maintained ABS system, without any active ABS Diagnostic
Trouble Codes (DTCs). Have active DTCs repaired by a qualified
technician. Any ABS DTCs will cause Wingman Advanced to
deactivate.
Importance of Brake Maintenance – Optimal Wingman Advanced
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.
System Problems – If a problem with the Wingman Advanced system
is detected, depending on the vehicle manufacturer, typically there
will be a message on the dashboard display. Depending on the type
of problem detected, the system will determine if the vehicle may
continue normal cruise control functions (without the benefits of
Wingman Advanced), or whether all cruise control functions should
be disabled until service is performed. The system should be serviced
as soon as possible to restore full Wingman Advanced functionality.
Radar Inspection – The driver should visually inspect the radar and
mounting bracket regularly and remove any mud, snow, ice build-up,
or other obstructions. 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.
Radar Damage / Misalignment / Tampering – In cases where the
bumper and/or radar have sustained any damage, are misaligned, or
if you suspect that the radar has been tampered with, do not use the
cruise control until the vehicle has been repaired and the radar realigned. In addition, an indicator on the dash typically will illuminate
if the system detects any of these conditions. Consult your vehicle’s
operator’s manual or contact Bendix for more information.

The Bendix ESP Stability System
All vehicles equipped with the Bendix® Wingman® Advanced™
system are also equipped with the Bendix ® ESP® stability
system. The Bendix ESP stability system is an always ready,
full-stability system which monitors vehicle performance and,
when necessary, automatically intervenes to reduce the throttle
and/or apply the foundation brakes to help you maintain stability
during potential loss-of-control or rollover events.
The Wingman Advanced system uses the ESP system to help
maintain vehicle stability during automatic brake applications
on slick surfaces.
The Bendix ESP stability system and the Wingman Advanced
system do not replace the need for the driver to remain alert,
react appropriately and in a timely manner, and use safe driving
practices.

The Bendix Wingman Advanced™ System Overview
®
®
The Wingman Advanced system is an integrated combination of three
features:
• Adaptive cruise control with braking;
• Alerts (three types of alerts); and
• Collision mitigation technology.
See the diagram below.
Vehicle Equipped with Bendix
Wingman Advanced
®
®

AM
RADAR BE

Forward Vehicle
NOT TO SCALE
The STRIPED area approximates
the zone where the collision
mitigation feature is ready to
intervene with up to two-thirds
of the vehicle’s braking capacity,
if needed, as long as the vehicle
is traveling above 15 mph.
The GRAY area approximates
the zone where the Wingman
Advanced system – when cruise
control is set – is ready to
intervene with up to one-third of
the vehicle’s braking capacity, if
needed.
What Features are Included in the
Bendix Wingman Advanced system?
Part One: Adaptive Cruise Control with Braking
Think of the adaptive cruise control with braking feature as an additional
upgrade to ordinary cruise control. When using cruise control, your vehicle
not only will maintain the set speed, but the system also will intervene,
as needed, to help maintain a set following distance behind the vehicle
in front of you.
Using a radar (with a range of approximately 500 feet) mounted to the
front of your vehicle, the Wingman Advanced system reacts ONLY to
vehicles moving in the same direction as you. (The system DOES NOT
respond to side-to-side moving traffic or oncoming traffic.)
See the GRAY area in the diagram above. The adaptive cruise control
with braking feature is designed to help maintain a set following distance
between your vehicle and the vehicle ahead when cruise control is set.
10
Once cruise control is set and the system is maintaining a set following
distance between you and the vehicle in front:
•
If the vehicle in front of you slows down below your cruise control’s
set speed, the system will intervene, as necessary, in this order:
(a) reduce the engine throttle, then
(b) apply the engine retarder, then
(c) apply the foundation brakes,
in an attempt to maintain the set following distance
behind the vehicle ahead. NOTE: If during the
intervention, it is necessary to apply the foundation
brakes, the vehicle will not automatically resume the
cruise control set speed.
• If the vehicle ahead slows, below your cruise control’s set speed,
but then accelerates away and the Bendix® Wingman® Advanced™
system did not need to use the foundation brakes, the system will
automatically accelerate back to the original cruise control set speed,
and again maintain a set following distance behind any vehicles
ahead of you.
Because the Wingman Advanced system operates along with normal
cruise control, all the typical features built into cruise control work as
usual. For example, limits imposed by factory-set road speed governors,
etc. are fully supported by the Wingman Advanced system.
Part Two: Alerts
Bendix Wingman Advanced also assists by giving audible and visual alerts,
whether or not cruise control is on. See Pages 19-20 for more information
on the three types of alerts you may hear and/or see displayed.
Part Three: Collision Mitigation Technology
See the STRIPED area in the diagram on page 10. Wingman Advanced’s
collision mitigation technology is designed to be ready to react to the
presence of moving vehicles in front of your vehicle (whether or not cruise
control is set). Collision mitigation interventions can be up to two-thirds
of the vehicle’s braking capacity. The system provides the driver with
an alert before an intervention occurs. You must immediately act to
potentially avoid, or lessen the severity of, a collision.
11
The Bendix Wingman Advanced™ System Components
®
®
The Wingman Advanced radar locates and tracks moving vehicles. The
radar is located at the front of your vehicle – either on the bumper or just
behind it on a cross-member. When located behind the bumper, in some
cases the unit also may be behind a protective covering that allows the
radar signal to pass through.
The Bendix® Wingman® Advanced™ radar is pre-aligned at the factory and
no adjustment should be needed. If the radar becomes misaligned, (or
any other system problem is detected) a message, or light on the dash
lets the driver know that service is needed.
Above: Examples of radar sensors.
System Display
Driver information about the Wingman Advanced system is either fully
integrated into the vehicle dashboard, or uses the Bendix® Driver Interface
Unit (DIU). Although the system functions the same, how the alerts are
displayed to the driver can be different. See the Alerts and Warnings
section of this manual on pages 19-21 for more detailed information
about the alerts.
NOTE: For some integrated systems,
the volume level of the alerts is not
adjustable, nor can they be switched
off.
12
The Adaptive Cruise Control with Braking Feature
NOTE: Whenever the cruise control is set, the adaptive cruise control with
braking feature is also set. You can not engage cruise control without
®
®
also using all the features of the Bendix Wingman Advanced™ system.
Setting Cruise Control
Activating the adaptive cruise control with braking feature is as easy as
using ordinary cruise control.
Examples of cruise control switches
First, switch on the cruise control. Accelerate your vehicle to the cruise
control speed you wish to maintain, then press the cruise control set
switch. The adaptive cruise control with braking feature is now ready
and will help you maintain a set following distance.
Once the cruise control speed is set, a
green cruise-enabled icon (or similar) will
illuminate on the instrument panel. If
the cruise-enabled (or similar) icon does
not illuminate, the cruise control is not
functioning normally. Please refer to your
vehicle operator’s manual to double-check
the location of the icon and for further
troubleshooting information.
Some vehicle manufac turers use the
instrument cluster to momentarily show the
cruise control set speed to the driver.
Example of Driver
Interface Unit (DIU)
detected forward
Vehicle display
Where the Driver Interface Unit (DIU) display is used, a text message will
provide the set speed information.
The driver can switch the adaptive cruise control with braking feature off
manually by either stepping on the brake, or switching OFF the cruise
control.
13
NOTE: Cruise control will automatically cancel whenever the Bendix®
Wingman® Advanced™ system applies the foundation brakes. You can
verify the system is disengaged by observing that the cruise-enabled
icon is no longer illuminated. You must resume or set cruise control in
order to regain normal cruise control functionality and to reengage the
adaptive cruise control with braking feature of the Wingman Advanced
system.
The Forward Detected Vehicle Icon
When cruise control is switched on and set, and a vehicle ahead of you is
detected by the radar, the forward detected vehicle icon (or similar) on
the vehicle dashboard will illuminate.
This is an indication to the driver that the Wingman
Advanced system is actively managing the distance
between your vehicle and the vehicle ahead, and that the
system may automatically intervene.
Adjusting the Cruise Control Speed
Use the switch(es) provided by the vehicle manufacturer to set your cruise
control speed. When adjusted, your set speed will typically be indicated
on the vehicle dash, message center, or speedometer, etc.
What is Following Distance?
Following distance refers to the time gap – measured in seconds –
between the vehicle with Wingman ACB and the vehicle ahead. The
actual physical distance between the two will vary based on the speeds
of both vehicles; however, the set gap will remain the same for all set
cruise speeds.
Advanced Collision Mitigation Feature Operation
Whenever the vehicle is traveling above 15 mph, the Wingman Advanced
collision mitigation feature is ready to intervene, if needed. It does
not require cruise control to be set. The collision mitigation feature of
Wingman Advanced will automatically alert you and apply up to twothirds of the vehicle’s braking capacity, if a collision with the detected
forward vehicle is likely to occur. You, the driver, must immediately act
to potentially avoid, or lessen the severity of, a collision.
Automatic Foundation Brake Applications
The vehicle automatically manages foundation braking priorities among
the various vehicle systems that use the foundation brakes, such as
Wingman Advanced, Bendix® ESP® (Electronic Stability Program), Bendix®
ATC (Automatic Traction Control), and the Bendix® ABS (Antilock Braking
System).

Expect the Wingman Advanced system to do this:
Steps on the brake.
(During a collision
mitigation event)
The driver is always in control and is able to apply
full braking power.
Steps aggressively on
the accelerator. (During
a collision mitigation
event.)
The driver is always in control. His/her actions
override any Wingman Advanced system actions.
Note: If cruise control is engaged, it will be
overridden until the accelerator is released; then
cruise control will resume the original set speed
automatically.
Steps on the brake.
(When in cruise.)
Cruise control will be cancelled.
Steps on the
accelerator. (When in
cruise.)
Cruise control will be overridden until the
accelerator is released; then cruise control will
resume the original set speed automatically.
Switches on the cruise
control.
Nothing. The adaptive cruise control with braking
feature will not engage until the driver sets the
cruise control speed.
Switches off the cruise
control.
The adaptive cruise control with braking feature
will turn off; the collision mitigation feature
remains active and ready to intervene. The driver
will continue to hear all alerts as needed.
Sets the cruise control
speed.
The adaptive cruise control with braking feature
is automatically activated, and your vehicle
maintains set speed and following distance
behind the vehicle ahead.
Covers or blocks the
radar.
The Wingman Advanced system performance will
be diminished or even disabled and a Diagnostic
Trouble Code (DTC) will be set. A blockage will
also affect engine cruise control availability.
Use normal cruise
control “+/-” switch.
Vehicle speed increased (+) or reduced (-)
to achieve the new set speed while actively
maintaining the following distance with the
vehicle ahead, if one is present within 500 feet.
NOTE: The system responses above are typical, but may vary from the descriptions
shown here by vehicle manufacturer, or earlier versions of the Wingman Advanced
system. These represent examples of driver actions and typical Wingman
Advanced system responses, however this chart does not attempt to cover all
possible situations.

Alerts and Warnings
®
®
The Bendix Wingman Advanced™ system is a unique, patented system
that functions differently than other cruise control/forward collision alert
and mitigation systems. It is important for YOU to fully understand the
system’s features, especially the driver indications and alerts.
Three main alerts provided by the Wingman Advanced system are the
Impact Alert (IA), Following Distance Alert (FDA), and Stationary
Object Alert (SOA). All of the alerts are always ready to alert the driver,
whether or not you are using cruise control.
WARNING: Any audible and/or visual alert by the system means
that your vehicle is too close to the vehicle ahead and the driver
must immediately act to potentially avoid, or lessen the severity
of, a collision.

The Impact Alert is the most severe
w a r n i n g i s s u e d by t h e W i n g m a n
Advanced system. This alert indicates
that a collision with the detec ted
forward vehicle is likely. The driver must
immediately act to potentially avoid, or
lessen the severity of, a collision. The
Impact Alert is ready to alert the driver
whenever the vehicle is moving above
15 mph.
When activated, the IA will sound and a visual
message/icon typically appears on the dash
screen or Bendix® Driver Interface Unit (DIU)
display. The actual sound/display method
varies by vehicle manufacturer.
NOTE: The Impact Alert is typically accompanied by automatic brake interventions. The
Wingman Advanced system will apply up to
two-thirds of your vehicle’s braking capacity.
The driver must apply additional braking, when
necessary, to maintain a safe distance from the
vehicle ahead.

Following
Distance Alert
(FDA)
The Following Distance Alert (FDA) provides
both audible and visual alerts whenever
the distance between your vehicle and the
detected forward vehicle ahead is less than
the one and a half (1.5) seconds* and getting
closer. Once the audible alert is given, the
driver should increase the distance between
his/her vehicle and the vehicle ahead until the
audible alert stops.
• Always ready
The FDA is ready to alert the driver whenever
the vehicle is moving above five (5) mph. If the
following distance continues to decrease, the driver
will hear more rapid audible alerts. When the FDA
reaches its highest level, typically a red LED also
illuminates on the instrument cluster. The FDA may
be accompanied by a visual alert.

- a continuous tone
will also sound.
NOTE: Entering a curve
may reduce the alert
time to less than three
(3) seconds.
Stationary Object Alert (SOA) – The
Bendix ® Wingman® Advanced™ system
will give up to three (3) seconds alert to
the driver when approaching a detected,
sizable, stationary object with metallic (radarreflective) surfaces in your lane of travel.
This alert indicates that a collision with a
stationary object is likely and the driver
must immediately act to potentially avoid,
or lessen the severity of, a collision.
The SOA is ready to alert the driver whenever the
vehicle is moving above ten (10) mph.
The driver should be especially careful when
approaching certain types of vehicles and objects.
The Wingman Advanced radar may not be able to
detect objects with limited metal surfaces (such
as recreational vehicles, horse-drawn buggies,
motorcycles, logging trailers, etc).

Special Alerts
Brake Overuse Warning – The Bendix® Wingman® Advanced™ 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.
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.
The driver 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, the driver should not reset cruise
control for at least 20 minutes. This gives the brakes time to
cool down. If the driver chooses to reset cruise control during
that 20 minute period, Wingman Advanced interventions will be
limited to de-throttling and engine retarder only. The system will
automatically disable all Wingman Advanced system foundation
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). The driver will continue
to receive alerts, but ALL Wingman Advanced interventions
(de-throttling, engine retarder or brake applications) will be
disabled until the next ignition cycle.
Wingman® Advanced™ Diagnostic Trouble Codes
The Bendix ® Wingman® Advanced™ system is monitored and if any
malfunction is detected, a Diagnostic Trouble Code (DTC) will be set and
the driver will be alerted. The exact alert given depends on the vehicle
manufacturer: refer to your vehicle operator’s manual and the Bendix
Service Data Sheet SD-61-4962 for more information.
Potential False Alerts
The Wingman Advanced system should have significantly fewer false
alerts than earlier systems. Radar technology is not perfect, and false
alerts sometimes occur. Radar misalignment will likely lead to increases
in false alerts. Drivers should take into account the road conditions, and
21
any other factors they are encountering, as they choose how to react to
any alerts they receive from the Bendix® Wingman® Advanced™ system.
When Not to Use Cruise Control
The adaptive cruise control and braking feature in Bendix® Wingman®
Advanced™ 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® Advanced™ 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.
Construc tion 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, may be difficult for the radar to identify. It
is the driver’s responsibility to be aware of these types of
vehicles and to slow down if necessary.

Additional Operational Notes
Adjusting the Alert Volume
®
The Bendix Wingman® Advanced™ system audible alerts are pre-set at
the factory for fully integrated systems and can not be turned off by the
driver, nor can the volume be adjusted, unless configured to do so. For
systems using a Driver Interface Unit (DIU) display, see the Service Data
Sheet (SD-61-4962) for information about volume adjustment.
Passing a Vehicle/Changing Lanes
With cruise control set, if the driver decides to change lanes or pass a
vehicle by applying the throttle, the vehicle being passed will no longer
be detected by the radar.
When No Other Vehicles are Present
When no forward vehicle is within range of the radar, your vehicle will
maintain its set speed just like ordinary cruise control.
Radar-Reflective Stationary Vehicles & Objects
The driver should be attentive to stopped vehicles and objects on the
roadway.
The Bendix® Wingman® Advanced™ system will give up to three (3)
seconds alert to the driver when approaching a detected, sizable,
stationary object with metallic (radar-reflective) surfaces in your
lane of travel.
The SOA is ready to alert the driver whenever the vehicle is moving
above ten (10) mph. The SOA is an alert only. No intervention
actions (such as de-throttling, engaging the engine retarder
or applying the brakes) will be taken. This alert indicates that
a collision with a stationary object is likely. The driver must
immediately act to potentially avoid, or lessen the severity of, a
collision.
Metallic Objects May Impair the Radar – Objects that are radarreflective–such as crash barriers, guard rails, construction zone
barricades, and tunnel entrances–may impair the function of the
radar.
23
Pedestrians, Animals, Non-Metallic
and Limited-Metallic Objects
Pedestrians, Animals, Non-metallic or Limited-metallic Objects –
The Bendix® Wingman® Advanced™ system will not warn or react
to pedestrians, animals, and non-metallic objects. The Wingman
Advanced system may not warn or react to limited-metallic
objects (such as recreational vehicles, horse-drawn buggies,
motorcycles, logging trailers, etc).
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 radar. The adaptive cruise
control 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 and you are following
3 seconds behind a vehicle traveling at 45 MPH that just entered a sharp
curve. If the vehicle ahead is no longer detected as you travel around the
curve, the Wingman Advanced system will delay the vehicle acceleration
back to 50 MPH for 3 seconds.
The operator should be especially attentive to the Wingman Advanced
system behavior through curves. In some cases, when traveling
around a curve, the radar may lose the vehicle ahead and attempt to
accelerate when resuming the set speed.
It is also possible for the Wingman Advanced system to begin tracking
vehicles in other lanes when traveling around curves. In cases where the
Wingman Advanced 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 the driver determines that a hazard or unsafe condition exists, you
should take all necessary actions immediately. Never wait for the
Wingman Advanced system to intervene.
Safe operation and control of the vehicle is the responsibility of the
driver at all times. If the driver applies the brakes, cruise control will
disengage automatically, and no Wingman Advanced intervention
will occur.
24
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® Advanced™ system to intervene.
Vehicles Crossing Your Path or Coming Towards You
The Bendix® Wingman® Advanced™ system reacts ONLY to vehicles
moving in the same direction as your vehicle. The Wingman
Advanced 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.

System Maintenance and Troubleshooting
Importance of Foundation Brake Maintenance – Optimal
Wingman Advanced 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 Advanced
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.
25
Preventive Maintenance:
®
®
The Bendix Wingman Advanced™ system is relatively maintenance free.
The key items to keep the system functioning properly include:
1. Keep the radar lens clean and free of obstructions.
®
2. Visually inspect for any damage to the bumper or the Bendix
®
™
Wingman Advanced 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® Advanced™ System Isn’t Working:
If the Bendix Wingman Advanced 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
Advanced 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. The Wingman Advanced system will alert the driver and activate
the foundation brakes when a collision with a detected forward
vehicle is likely. The Bendix Wingman Advanced 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 three driver alerts always available?
Yes. All three driver alerts (Impact Alert, Following Distance Alert and
Stationary Object 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 and the driver must
immediately act to potentially avoid, or lessen the severity of, a
collision.
A solid tone means you should actively apply the brakes because
the Bendix ® Wingman® Advanced™ 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 Advanced system detect stationary objects?
Yes. The system will give up to three (3) seconds alert when
approaching a detected, sizeable, stationary object with metallic
(radar-reflective) surfaces in your lane of travel.
5.
Can I use an aftermarket “deer guard” on my truck?
The installation of aftermarket deer guards is not recommended, and
could impair operation of the radar. See Bendix Technical Bulletin
TCH-061-003.
