Important Harness Adjustments

According to the American Academy of Pediatrics:
All infants should ride rear-facing until they have reached at least 1
year of age and weigh at least 20 pounds (9.1 kg). That means that
if your infant reaches 20 pounds (9.1 kg) before her first birthday, she
should remain rear-facing at least until she turns 1 year old. It is best
for children to ride rear-facing to the highest weight or height allowed
by the manufacturer.
Rear-Facing
Use rear-facing only with children:
• who weigh between 5 and 35 lbs (2.3 – 15.9 kg) and
• the top of the child's head is at least 1" (2.5 cm) or
more below the top of the child seat (Fig. A) and
• the harness straps are in the nearest slots at or
below the child's shoulders.
If the child cannot be secured within these requirements because the
child exceeds height or weight requirements, review the forward-facing
guidelines on page 7.
If the child cannot be secured within these requirements because the
child is too small, selection of a different child seat (such as an infant
carrier) may be required.
IMPORTANT:
WARNING!
Do NOT use the child seat rear-facing if any of the following apply:
• the child is less than 5 lbs (2.3 kg) in weight or
• the child exceeds 35 lbs (15.9 kg) in weight or
• the top of the head is less than 1" (2.5 cm) from the top of the child
seat (Fig. A) or
• the harness straps are in a slot above the child's shoulders.
