Q:
What if the top of my child's shoulders is above
the shoulder belt slots for the five-point child
restraint harness system?
A:
A child whose shoulders are above the shoulder belt
slots for the five point child restraint harness system
shouldn't use this child restraint. Instead, the child
should sit on the vehicle's regular seat cushion and
use the vehicle's adult safety belts.
BEFORE YOU USE THIS CHILD RESTRAINT,
BE SURE THE TOP OF THE CHILD'S
SHOULDERS IS BELOW THE SLOTS THAT
THE HARNESS GOES THROUGH. A CHILD
WHOSE SHOULDERS ARE ABOVE THOSE
SLOTS COULD BE INJURED DURING A
SUDDEN STOP OR CRASH. IF THE TOP OF
THE CHILD'S SHOULDERS IS ABOVE THE
SLOTS, DON'T USE THIS CHILD RESTRAINT
WHILE THE VEHICLE IS IN MOTION.
Securing a Child in the Built-In Child
