FORD 2003 Explorer Sport Trac v.4 - Manual (Page 99)

Installing child safety seats in combination lap and shoulder belt
seating positions
Air bags can kill or injure a child in a child seat. NEVER place a
rear-facing child seat in front of an active air bag. If you must
use a forward-facing child seat in the front seat, move the seat all the
way back.
Children 12 and under should be properly restrained in the rear
seat whenever possible.
1. Position the child safety seat in a
seat with a combination lap and
shoulder belt.
2. Pull down on the shoulder belt
and then grasp the shoulder belt
and lap belt together.
