HOW TO SETUP
ADJUSTING HARNESS STRAP HEIGHT:
FOR CHILD USE FORWARD-FACING
Correct fitment of the harness is very important as it restrains the child in the restraint. The harness
must fit firmly around the upper torso of the child and be positioned so as to leave the child's arms
and legs free.
The shoulder straps must be in the slots which are nearest to the child's shoulders, but not more than
25mm lower than the child's shoulders. When the child's shoulders reach the upper shoulder height
marker, the child is too large for the child restraint.

of the restraint.
