Dorel TRIOFIT User manual

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 the levers at the upper sides of the headrest 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.

fully upright position. If forward facing in harness or booster mode, use
semi-reclined position only if needed to make child restraint flush against

Choosing Rear Facing, Forward Facing, or
Booster Seat
Your child’s height, weight, and age determine how your child
restraint should be placed in the vehicle.
Please talk to your doctor about the best option for your child.
See page 3 to
adjust internal
harness system
See page 3 to
adjust internal
harness system
See page 16 to
store internal
harness system
WARNING: Verify your child’s weight and height
(do not guess) before choosing the child restraint’s
placement.
Children up to 1 year of age must ride rear facing.
The American Academy of Pediatrics recommends
that children remain rear facing until they are at least
2 years old.
In this child restraint, your child can remain rear facing
up to 40 lb (18 kg) and up to 40 in. (101.6 cm).
The American Academy of Pediatrics recommends
that children remain in a five-point harness until
they outgrow their forward-facing harnessed child
restraint.
This typically occurs around age 4, but some children
outgrow them sooner and others not until later.
