Detroit Assurance Collision Mitigation System (CMS)
The Detroit Assurance collision mitigation system (CMS) is a safety system. The system uses a radar sensor that is mounted on the crossmember of the front frame shown in Fig.. Plus a windshield-mounted multipurpose camera described in 'Detroit Assurance Vehicle Cameras.' The radar and the camera provide active features with information that can control the truck.
The system can track vehicles up to 820 ft (250 m) ahead, can sound a warning, and apply the brakes if necessary.

Important: Do not mount any attachments in front of the radar distance sensor. Do not paint or affix items over the distance sensor cover. Keep the cover free of mud, ice, and snow. Attachments mounted in front of the distance sensor, such as a crash guard, and objects on the sensor cover can impair the sensor's operation.
Driver's Display
The 108SD Plus and 114SD Plus is equipped with an instrument cluster unit common (ICUC). The driver's display, on the ICUC, presents the status and warnings from the different features that make up the Detroit Assurance safety system.
The standard core features of Detroit Assurance on the Freightliner 108SD Plus and 114SD Plus include active brake assist 5 (ABA5), adaptive cruise control (ACC) with fixed headway, tailgate warning, and lane departure warning (LDW) with a fifteen minute timeout switch.
