Hercules Prime is placed in the desired position on the car seat. The backrest of

3-point safety belt is first passed through the upper green belt guide (Fig. 4), then
through the belt guides located in the pelvic area (Fig. 5+6). Both belt guides must
be used in the pelvic area. The belt is then locked in the buckle with the belt tongue
(Fig. 7) and the belt run must be checked for twisting.
Tip: Installation in the vehicle is easier if you unfold the folded Hercules Prime after
