The lap portion of the belt must be adjusted rmly rst, and then the harness, so that 
the belt is not lifted off the child's lap when the harness is adjusted.

NOTE: The shoulder straps must be in the slots which are nearest to the child’s 
shoulders but not lower than the child’s shoulders. This is achieved with the headrest 
slightly above the child’s shoulders.
