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: See Adjusting Harness Slot Height on page 31.

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

seat (Fig. A) or

the child exceeds 49” (124.5 cm) in height • or

than would be used when the seat is upright.
