A radar sensor mounted in the front bumper of a Mack Trucks Pinnacle helps warn drivers of the potential for a rear-end collision. Bendix Wingman Advanced – A Collision Mitigation Technology, provides adaptive cruise control with braking that actively intervenes to help drivers maintain a safe following distance by reducing the throttle, engaging the engine retarder, or if necessary applying the foundation brakes to help avoid collisions or at least lessen the severity. The system is always available above approximately 10 mph, even if cruise control is not set, and provides following distance and stationary object alerts.
