- Airbags: The airbags in a Mercedes-Benz S500 are designed to inflate rapidly and provide a cushion between the occupant and the hard interior of the car in the event of a collision.
- Seat belts with pre-tensioners and load limiters: Pre-tensioners are designed to tighten the seat belt instantly upon impact, reducing slack and helping to keep the occupant in place. Load limiters are designed to reduce the force exerted on the occupant in the event of a severe collision.
- Impact sensor: The impact sensor in a Mercedes-Benz S500 is used to detect a collision and trigger the deployment of the airbags and pre-tensioners.
