How does Mercedes' Pre-Safe system work?

Model: Mercedes Mercedes Various
Part: Onboard computer

On many Mercedes vehicles, a device called "Pre-Safe" is installed, which constantly monitors driving conditions, such as speed, distance from other vehicles, or steering angle. If the system detects a high risk of collision, it activates preventively, implementing a series of measures to protect the occupants: it closes the windows, tightens the seat belts, finds the optimal seat positions, preloads the brakes, gives audible and visual warnings to alert the driver of the danger, and in some vehicles the system signals to following vehicles the danger of an imminent rear-end collision with a rapid flashing of the hazard lights.
