If the M-Class senses certain rollovers, it will
automatically deploy the seat-belt Emergency
Tensioning Devices (ETDs) to help reduce
occupant movement and, if deemed necessary,
inflate the Window Curtain Air Bags
Integrated Restraint System
Every M-Class offers the comprehensive protection of eight standard air bags,5
including adaptive dual-stage air bags for the driver and front passenger, front-seat
mounted side-impact air bags, rear side-impact air bags and, for all four outboard
occupants, Window Curtain Air Bags that help protect against head injury and
broken glass in a side impact exceeding a preset threshold, or in certain rollovers.
Active Front Head Restraints also work to help prevent whiplash-type neck
injuries in the event of a rear-end collision exceeding a preset threshold.
Advanced front-impact protection
The front-end structure of the M-Class incorporates upper and
lower elements to provide two levels of energy management in
frontal impacts with a variety of vehicle sizes. Features such as
an ellipsoidal front bulkhead and reinforced wheel arches help
channel some of the force from a frontal impact over, under and
around the passenger cabin.

Here's a writeup with pictures how the ETDs work. For Presafe the car also has to have reversible belt tensioners.
