Detroit Assurance 4.0
Detroit Assurance 4.0 (DA 4.0) is a driver safety sys-
tem that uses a bumper-mounted radar and an op-
tional windshield mounted camera to communicate
information to the vehicles’s brakes, engine, and
transmission.
The system can track vehicles up to 820 feet (250
meters) ahead, and, if necessary, will sound a warn-
ing and apply the brakes.
IMPORTANT: Do not mount any attachments in
front of the radar distance sensor. See
Fig. 5.1.
Do not paint or affix items over the distance
sensor cover. If attachments are mounted in
front of the distance sensor, such as a crash
guard, they can impair the operation of the dis-
tance sensor.
To avoid malfunctions, clean the cover of the dis-
tance sensor regularly.
The windshield mounted forward-facing camera is
required for DA 4.0 Lane Departure Warning (LDW).
See
Fig. 5.2.
The windshield must be clean, unobstructed, and
without damage for proper operation of the camera.
Regularly clean the area of the windshield used by
the camera to avoid incorrect lane detection by LDW.
The driver should switch on the windshield wiper to
clean the windshield and remove snow and ice from
the windshield.
If the area of the windshield used by Lane Departure
Warning is damaged, the windshield must be re-
placed.
Multipurpose Camera 1 (MPC1)
The camera detects the raised reflectors and reflec-
tive paint in lane markings.
If the vehicle is equipped with Bendix SafetyDirect,
this camera records video of the trucks activity during
severe collision mitigation events. In such situations
a total of 20-30 seconds of recording is transmitted
to the SafetyDirect web portal.
