What Does the PRESAFE® Mercedes-Benz System Do?

The PRESAFE® collision preparedness system uses a variety of sensors to detect impending collisions, and will automatically and immediately activate its features to reduce the effects of the impact. There are several Mercedes-Benz PRESAFE® sensor locations. If you want to check on your sensors, you should look under the front bumper and near your three-pointed star logo.

Here is what Mercedes-Benz PRESAFE® does:

  • Front head restraints adjust for maximum crash protection to reduce and prevent passenger injuries.
  • The windows and sunroof close if a rollover is possible. This prevents debris like broken glass and vehicle parts from entering the cabin.
  • Tension in the front safety belts is increased to protect occupants from injury or reduce the severity of injuries.
  • In select models, PRESAFE® Sound emits a tone that causes a reaction in the inner ear to protect the eardrum from damage.

The PRESAFE® and PRESAFE® Sound safety systems work in tandem with other Mercedes-Benz features to give you more peace of mind while exploring East Greenwich and beyond.

Are you considering a vehicle with PRESAFE® PLUS? This technology builds upon the capabilities of PRESAFE® in order to offer additional protection in rear-end collisions.

What Does “PRESAFE® Functions Limited” Mean?

If your vehicle displays the dashboard warning “PRESAFE® Functions Limited,” Mercedes-Benz service may be needed. This usually appears if a sensor needs adjustment or cleaning, and it might pop up if and when your sensors become blocked by snow, ice, or mud. Although you can identify the Mercedes-Benz PRESAFE® sensor locations with your owner’s manual and take a look at home, you can also schedule service and let one of our experienced certified technicians take a look.

If you’ve cleaned your sensors and the message has not disappeared, it’s time to make an appointment. It’s likely that one or more of the radar sensors has been damaged and/or needs to be replaced. If you notice any signs of water damage inside the sensor casing, you’ll definitely need to replace the feature.

“PRESAFE® Inoperative” in Your Mercedes-Benz: Meaning & Next Steps

If you see the alert “PRESAFE® Inoperative” in your Mercedes-Benz, the meaning of the message may not immediately be clear! Indeed, the only way to determine the cause of this issue is to run a diagnostics test. As specified on page 382 of this recent Mercedes-Benz C-Class owner’s manual, “PRESAFE® Inoperative” means that your systems are malfunctioning; visit a qualified Mercedes-Benz service center at the earliest opportunity. If you ever see “PRESAFE® Inoperative” in your Mercedes-Benz C 250 or your GLE, you should schedule service with our dealership.
