Following
Distance Alert
(FDA)
• Always ready
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 (1½) 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 5 mph (8km/h). 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.

Stationary Object
Alert (SOA)
• Always ready
Stationary Object Alert (SOA) –
The
Bendix
®
Wingman
®
ACB system will give up
to three (3) seconds alert time to the driver
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 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 10 mph (16 km/h).
The driver should be especially careful when
approaching certain types of vehicles and
objects. The Wingman ACB radar may not be
able to detect objects with limited metal surfaces
(such as recreational vehicles, horse-drawn
buggies, motorcycles, logging trailers, etc).
