WARNING! REAR-FACING use of this child seat is ONLY for
children who meet ALL of the requirements below. If the child cannot
be secured within these requirements because they are too small, use
of the infant positioning insert or selection of a different child seat (such
as an infant car seat) may be required. If the child cannot be secured
within these requirements because the child is too large, review the
forward-facing guidelines on page 7.
Important Child Seat Usage Information
All infants must ride rear-facing at least until they have reached 1
year of age and weigh 20 lbs (9.1 kg).
An infant positioning insert may be necessary for small infants to
achieve a snug fit if the child is under 12 lbs and the lowest harness
slots fall above the infants shoulders. The Infant positioning insert is
sold separately at select retailers and on www.britaxusa.com.
Britax advises that parents strongly consider the following when using
this child seat.
• Children should be secured with a harness system until they exceed
the weight or height limits specified.
• Britax recommends that children ride rear-facing to the highest weight
or height specified.

• who weigh between 5 and 40 lbs (2.3 –
18.1 kg) and
