Before Deployment After Deployment
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.

SYSTEM.
1. The S4S is to be used in a specic vehicle application and seating position,
and only with a specic model seat.
2. Always follow the vehicle manufacturer’s installation guide. Use this
installation guide in addition to the vehicle manufacturer’s guide.
3. Always disconnect vehicle batteries and turn off vehicle switch before
accessing electrical connection.
4. DO NOT PUNCTURE DRILL OR APPLY HEAT TO S4S.
5. DO NOT MOUNT ANYTHING NEAR THE S4S that could interfere with

6. The master roll sensor must be vehicle mounted before any electrical con-
nections associated with S4S system are made.
7. The S4S is only designed to activate once. If the system is activated or is
damaged, unit must be replaced by authorized personnel.
HAZARDOUS OPERATION
Applying power prematurely could deploy occupant protective devices, causing

Product Identication
1. Locate product identication label. This is located on the front mounting brack-
et of the unit. See FIGURE 2
2. Verify your unit is the proper system for your conguration.
Mounting the S4S Unit to Vehicle Floor
1. Use only pre-drilled mounting holes.
2. Metal to metal contact is mandatory on all mounting points.
3. Position the unit in place. See FIGURE 3
4. Make sure wiring harness is free and not pinched. DO NOT MAKE WIRING
HARNESS CONNECTION TO UNIT AT THIS TIME.
5. Position the unit on the cab oor and align the holes in the oor with the front
mounting bracket. Using the proper Seagrave supplied mounting hardware
hand tighten the two front mounting bolts.
6. Next install the two rear mounting bolts which also secure the rear of the seat.
7. Finally torque each mounting bolt to the required specication.
ICP (InterConnect Point Bar)/Tether Connection
1. Make sure web tethers are routed per diagram on S4S, and not twisted,
pinched or damaged before unit is torqued. See FIGURE 4
2. Remove rubber band from tether-hook assembly and pull tether taut to check
for twists, pinches or damage. Make sure hook is oriented as shown.
3. Make sure seat is fully lowered.
4. Connect hook into ICP cable as shown. See FIGURE 5
