How Does PRESAFE® Work?

Using sensors, the PRESAFE® Mercedes-Benz system can detect potential accidents and take quick action to help protect you and your passengers. Once the system activates, it takes the following steps:

  • Tension is increased in the front seat belts.
  • Closes the windows and sunroof to prevent debris from entering the cabin during a rollover.
  • Adjusts the front head restraints for maximum crash protection.

This pre-collision system works to protect the hearing of occupants by emitting a “pink noise” that will cause a reaction in the inner ear during a crash. Working in tandem, the PRESAFE® and PRESAFE® Sound safety systems function together to protect drivers and passengers in Boulder City.
