AUTOMATIC FOUNDATION
BRAKE APPLICATIONS
The vehicle automatically manages foundation brake
priorities among the various vehicle systems that use the
foundation brakes, such as Bendix ® Wingman ® Advanced ™
system, Bendix ® ESP ® Electronic Stability Program,
Bendix ® ATC (Automatic Traction Control) and Bendix ®
ABS (Antilock Braking System).
NOTE: Cruise control will automatically cancel whenever
the Wingman Advanced system applies the foundation
brakes. You can verify that your cruise control 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.
Additional information, and complete troubleshooting
procedures for the Bendix ESP stability system, can be
found in the Bendix Service Data Sheet SD-13-4869.
1.2 SYSTEM COMPONENTS
The radar sensor (or radar) used in the Wingman Advanced
unit is located at the front of the vehicle – either on the
bumper or just behind it on a cross-member. See Figure 3.
FIGURE 3 - COMPONENT: RADAR SENSOR
The radar sensor is pre-aligned at the factory and no
adjustment should be needed. If the radar sensor becomes
misaligned (or a diagnostic trouble code is issued), either a
message – or light on the dash, depending on the vehicle –
lets the driver know that service is needed.
The Wingman Advanced system is either fully integrated
into the vehicle dashboard, or uses the Bendix ® Driver
Interface Unit (DIU). See Figure 4.
FIGURE 4 - BENDIX DRIVER INTERFACE UNIT (DIU)
Although the system functions the same, how the alerts
are displayed to the driver can be different. Where a DIU
(Driver Interface Unit) is used, all visual, text, and audible
indicators and alerts will be provided by the DIU. The DIU
allows the volume to be adjusted. See Appendix F.
Also see the Alerts and Warnings section of this manual
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.
1.3 ACTIVATING THE BENDIX ®
WINGMAN ® ADVANCED ™ SYSTEM
To have the Wingman Advanced cruise control with braking
features of the Wingman Advanced system (engine de-
throttle/retard, foundation brake interventions) the vehicle’s
regular cruise control must be switched on. See Figure 5
for examples of switches that may be used.
When the vehicle reaches the desired cruise speed, the
driver presses the cruise control set switch to activate the
system. The Wingman Advanced system will then engage
and help the driver maintain a set following distance behind
the vehicle traveling in front.
Once the cruise control speed is set, a cruise-enabled icon
(or similar) will illuminate on the instrument panel. If the
cruise-enabled or set (or similar) icon does not illuminate,
the Wingman Advanced system is not functioning normally.
Refer to the vehicle operator’s manual to double-check
the location of the icon, and for further troubleshooting
information.
The driver can switch off the Wingman Advanced system
manually by either stepping on the brake pedal or switching
off the cruise control.

IMPORTANT NOTE: Cruise control will automatically
cancel whenever Wingman Advanced applies the
foundation brakes.
