Install with lap belt as shown above.
WARNING!
• DO NOT use lock-offs for lap belt only installations.
• Your child seat may not perform as intended if the base of the child
seat is not flat on the vehicle seat.
• This child seat must not be used forward-facing for children less
than one year of age OR who weigh less than 20 lbs (9.1 kg).
• Some vehicle head restraints may
obstruct the harness adjuster from
reaching the highest position. If this
is the case, you may need to raise or
remove the vehicle head restraint. DO
NOT force the child seat head pad

so could cause the child seat not to
perform as intended.
