IMMI S4S User manual

What is the S4S?
S4S stands for Suspension Seat Safety System.
How does it work?
In the event of a side roll, the S4S unit is deployed by the master
roll sensor, pretensioning the seat belt, then pulling the seat to
its lowest position. The S4S is only effective when you wear your
seat belt. ALWAYS WEAR YOUR SEAT BELT.
