General Description
Detroit Assurance 4.0 (DA 4.0) is a driver safety system that uses a bumper-mounted radar and an optional 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 warning and apply the brakes.
Important: Do not mount any attachments in front of the radar distance sensor. See Fig.. 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 distance sensor.
Fig. 1, Forward Radar Location
To avoid malfunctions, clean the cover of the distance sensor regularly.
The windshield mounted forward-facing camera is required for DA 4.0 Lane Departure Warning (LDW). See Fig..
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 replaced.
