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.
Failure to read and follow these instructions may result
serious injury or death to the occupant.
