Mercedes-Benz PRESAFE® System Explained

Springing into action if a potential collision is detected, the Mercedes-Benz PRESAFE® system takes precautionary measures to ensure the safety of you and your passengers. Luckily, shoppers around San Jose and Newark will find this system available in many new Mercedes-Benz vehicles. See what this system can do, and learn more about additional Mercedes-Benz technologies at Fletcher Jones Motorcars of Fremont.

Functions of the Mercedes-Benz PRESAFE® System

Using sensors around your Mercedes-Benz vehicle, this system will detect if an accident is about to occur. Once sensed, PRESAFE® kicks in and takes multiple steps to protect vehicle occupants:

  • The front head restraints adjust, moving to the best position for preventing passenger injuries for maximum crash protection.
  • If there is the potential for a rollover, the sunroof and windows close to prevent debris from entering the cabin.
  • Tension is increased in the front safety belts.

Systems That Work With PRESAFE®

Aspects of the PRESAFE® system integrate with other Mercedes-Benz safety technologies, such as:

  • PRESAFE® Sound: On equipped vehicles, this system activates alongside PRESAFE® and emits a “pink noise” from the audio system to stimulate a natural reflex reaction in the human ear.
  • DISTRONIC PLUS®: Using the PRESAFE® system’s brake feature, this intelligent adaptive cruise control system will slow or stop your vehicle should a straight-ahead vehicle suddenly brake.
  • PRESAFE® Impulse Side: If you get into a head-on accident or a fender bender in the Bay Area, the front and rear crumple zones help protect you and your passengers. But what about a side impact collision? PRESAFE® Impulse Side was created for this very reason. If the system’s sensors detect impending side impact, a chamber within the front-seat side bolster is activated. The chamber inflates rapidly, moving the passenger toward the center of the vehicle so they’re further away from the door. During inflation, the relative speed between the vehicle’s side structure and the passenger’s torso is also reduced. Curious which vehicles are available with PRESAFE® Impulse Side? This pioneering technology is available on select models like the S-Class, but you can expect to see it introduced to more models in the near future.

Additionally, PRESAFE® uses the same sensors as other driver assists from Mercedes-Benz, including Active Lane Keeping Assist, Active Blind Spot Assist, and more.

Which Mercedes-Benz Models Include PRESAFE®?

From SUVs to roadsters, Mercedes-Benz includes the PRESAFE® system in a variety of new models for Milpitas drivers. You will find the system included in the following models:
