Harness: Shoulder straps are attached to a splitter plate behind seat. Pull
strap end in front of seat to tighten harness. Push lever at lower front of seat
and pull on shoulder straps to loosen. Lap straps are threaded through slots
at hips and run straight across under seat shell.
Harness slots: There are two sets of slots. To adjust harness for smaller
infant, route straps through lowest set of slots, below metal bar (diagram 1).
To use the lower set of harness slots, you must adjust headrest to lowest
position, you must use upper set of loops on harness positioned as shown
in diagram 2, you must use body pillow (diagram 3), and you must adjust
crotch strap to innermost position with crotch strap anchor on top of shell's
middle slot (diagram 4). Route harness straps and crotch strap through slots in
body pillow. When using upper set of harness slots, harness straps must be
routed over metal bar (diagram 5). Harness may be raised or lowered by
rotating both adjustment levers inward and lifting or lowering headrest
(diagram 6). Make sure the headrest and metal bar at rear of seat are locked
into position.
Crotch strap: There are three positions. Middle or innermost slot must
be used if child is rear-facing. Any slot may be used for forward-facing.
To change position, turn metal anchor under seat sideways and feed it
through slot to top of seat. Re-thread through desired slot and tug to be sure
anchor is flat underneath seat. If using harness slots below metal bar, crotch
strap must be routed as described in "Harness slots" section above.
