Found on many new Mercedes-Benz models, this system takes precautionary steps to ensure your safety.

What Does Mercedes-Benz PRESAFE® Do?

If a potential accident is detected while you’re navigating Fontana, the PRESAFE® system activates to protect you and your passengers from harm. Once activated, PRESAFE® takes the following measures:

• For maximum crash protection, the front head restraints adjust to the best position to prevent passenger injuries.
• The tension increases in the front safety belts to protect occupants from injury.
• The windows and sunroof will automatically close in order to prevent debris from entering the cabin and causing further injury.

Mercedes-Benz PRESAFE® Extensions

In addition to PRESAFE® protections, the system also works alongside with other Mercedes-Benz technologies to boost your safety. You can find Mercedes-Benz PRESAFE® working in tandem with systems like:

• PRESAFE® Sound: The PRESAFE® Sound system also activates when an impending accident is detected. This feature emits a “pink noise” from the audio system that will cause a natural reflex in the human ear which helps protect your hearing from the loud sounds that can come during a collision.
• DISTRONIC® PLUS: Working with the PRESAFE® Brake feature, this intelligent adaptive cruise control system uses PRESAFE® to slow or stop your vehicle should a straight-ahead vehicle brake suddenly.

The Mercedes-Benz sensors used for other safety and driver-assist features, like Active Lane Keeping Assist and Active Blind Spot Assist, are also used for PRESAFE®.

What Does “PRESAFE® Functions Limited” Mean?

If you’re driving in Upland and your vehicle displays the “PRESAFE® Functions Limited” alert, your vehicle may be in need of Mercedes-Benz service. This message can be seen on the vehicle’s information panel, which is located behind the steering wheel. This alert isn’t a cause for panic; most often, this simply involves cleaning the PRESAFE® sensors. Still, you’ll need to have a certified technician take a look.
