What is Mercedes-Benz PRESAFE®?

2019 mercedes-benz a-class



Mercedes-Benz PRESAFE® senses instability associated with an impending collision and takes action to help protect the cabin and its occupants. This system is standard on many new Mercedes-Benz vehicles, such as the C-Class and GLC, and adds an extra layer of safety and security to your San Diego drives. Learn more about this intelligent feature and how it works below!

How Does PRESAFE® Work?

What happens when the PRESAFE® Mercedes-Benz system senses that a collision or rollover is imminent? It’ll take the following steps to help keep you and your passengers protected:

  • The front head restraints adjust to the best position for preventing passenger injuries.
  • If a rollover is likely, the windows and sunroof close to help keep debris from flying into the cabin.
  • The front seatbelts tighten for greater protection from injury.

Additionally, some models like the E-Class and S-Class come with PRESAFE® Sound — an extension of PRESAFE®. When a collision or rollover is detected, PRESAFE® Sound emits a “pink noise” via the audio system to stimulate a natural reflex in the human ear to help protect your hearing during an accident.
