MAGIC BODY CONTROL®, our groundbreaking technology that scans the road and automatically adjusts the vehicle´s suspension to provide an unprecedentedly smooth ride, is just the latest innovation to be introduced to the world by Mercedes-Benz. 
PRE-SAFE®, A groundbreaking system that can help prepare the occupants for an accident before it happens, PRE-SAFE® can detect that certain types of collision might be imminent. In the precious moments before impact, it can snug the front seat belts and adjust the front head restraints to help optimize the effectiveness of the restraint systems.Safety first, when seconds count.
"PRE-SAFE® responds when active safety systems like ESP are fully engaged but not restoring control. If it senses a severe sideways skid, it can even close the windows and sunroof. And if no accident occurs, the seat-belt tensioners reverse, you reopen your windows, and continue on your way."
DISTRONIC PLUS® with PRE-SAFE® BrakeAn eye on the road ahead: Automated response to stopped traffic.
Even a moment of driver distraction can have life-changing results. With DISTRONIC PLUS®, advanced radar sensors vigilantly scan traffic ahead for stopped or slowing traffic. If the system senses that a collision is imminent, its PRE-SAFE® Brake feature automatically initiates up to 40% braking power, audibly alerts the driver, and engages the PRE-SAFE® system. When the driver brakes, 100% braking pressure is instantly applied. And should the driver fail to respond, the system can apply full braking on its own, serving as an "electronic crumple zone" to help reduce the intensity of a collision.
ATTENTION ASSIST®, Keeping an eye on you: Early warning for driver drowsiness.Even in the most exciting vehicle, a long journey can bring about driver fatigue. An industry first, ATTENTION ASSIST® takes note of over 70 parameters in the first minutes of a drive to get to know your unique driving style. As your journey continues, it can detect certain steering corrections that suggest the onset of drowsiness. It then considers a wide array of other factors, from crosswinds and road smoothness to how often you're interacting with the vehicle's controls and switches. If it all adds up to driver fatigue, ATTENTION ASSIST® sounds an alert encouraging you to stop for a rest.
