How a Mercedes-Benz responds to an accident.

In order to provide superior occupant protection, a Mercedes-Benz is engineered to be a fully integrated safety system. Should an accident occur, there are four different ways in which your vehicle is designed to respond. It will:

    Manage the impact

    Preserve the occupant space

    Provide a targeted response

    Reduce the rate of deceleration

Safety Innovations

Setting the standard for safety.

From the invention of the crumple zone to countless innovations in occupant protection and accident avoidance, the safety firsts of Mercedes-Benz often set a standard that all automobiles eventually follow. Today, Mercedes-Benz offers exclusive new breakthroughs to help make an accident less severe, less damaging, or even less likely. Here are just some of the ways in which a Mercedes-Benz can keep you even more safe and sound on the road.
  • Collision Prevention Assist

    Using radar to constantly monitor closing speeds between your Mercedes-Benz and the moving vehicles around it, this system determines whether or not a collision is likely, and can help you apply the ideal level of braking.

  • Blind Spot Assist

    This radar sensor system monitors both sides of your vehicle and warns you with visual and auditory signals if it detects a vehicle in your blind spot.


    To set your cruise control speed, this driver-assistance system combines automatic speed regulation with proximity control in relation to a vehicle traveling in front.

  • Lane Keeping Assist

    Uses a camera to recognize lane markings. If you begin to stray from your lane, the system can warn you by vibrating the steering wheel.


    Sensing that a collision might be imminent, PRE-SAFE® uses a network of sensors (many of them already serving other safety systems in the vehicle) to detect certain conditions which suggest that an accident is about to occur. It then tightens the front seat belts and adjusts the front head restraints and passenger seat, and can even close the windows and sunroof - all to better prepare the occupants for more effective results from the restraint systems.


    With advanced radar sensors scanning stopping or slowed traffic, this system can sense whether a collision is imminent and automatically initiate up to 40% braking power, audibly alert the driver, and engage the PRE-SAFE® system. Then, when the driver brakes, 100% braking pressure is instantly applied. And should a driver fail to respond, DISTRONIC PLUS® with PRE-SAFE Brake can apply full braking on its own, serving as an "electronic crumple zone" to help reduce the intensity of a collision.


    Using 70 parameters to better determine an individual's driving style, ATTENTION ASSIST® 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 a driver is interacting with the vehicles' controls and switches. If it all adds up to driver fatigue, ATTENTION ASSIST sounds an alert encouraging the driver to stop for a rest.


    Emits a short interference signal through the vehicle's sound system if the risk of a collision is detected. This signal can prepare the ears for the noise and lessen the risk of hearing discomfort or damage.


    In the event of a side impact, there is only a limited crumple zone available. In order to increase the size of this zone, PRE-SAFE Impulse Side moves the driver or front passenger out of the immediate danger zone before a crash even takes place.
