11. Now fasten the left and right halves of the shoulder
harness clip together. The purpose of this clip is to
help keep the harness positioned on the child's
shoulders.
An unfastened shoulder harness clip won't
help keep the harness in place on the child's
shoulders. If the harness isn't on the child's
shoulders, it won't be able to restrain the
child's upper body in a sudden stop or crash.
The child could be seriously injured. Make
sure the harness clip is properly fastened.
