Adjusting the Harness
IMPORTANT: The harness can be adjusted to three different heights.
Always ensure proper adjustment at or above your child's shoulders.
1. Pull the harness strap retainer away
from the seat back and turn 90
degrees to feed it through the harness
slot.
2. Push the harness retainer through the
appropriate harness slot to the back of
the seat.
3. Turn the harness retainer to its original
position as shown so it properly retains
the harness.
