Important Notes
• Do not install with the lower anchors for a child weighing
more than 35 lbs (15.8 kg) rear facing or 40 lbs (18 kg)
forward facing.
• Do not use the top tether strap with rear-facing installations.
• Ensure that the shell cover is properly secured behind
the red markers to allow for proper functioning of the
CLICKTIGHT mechanism (see page 36).
• Discontinue use of this child seat if it has been in a
moderate or severe crash. It is not necessary to replace a
car seat after a minor crash, defined by the US National
Highway Traffic Safety Administration (NHTSA) as:
a. The vehicle is drivable from the crash site; and
b. The vehicle door nearest the child seat was not
damaged; and
c. No vehicle occupants were injured; and
d. There is no visible damage to the child seat; and
e. The airbags (if present) did not deploy.
• Cover the child seat when the vehicle is parked in direct
sunlight. Metal parts of child seat could become hot
enough to burn a child.
• Store the child seat in a safe place when it is not being
used. Avoid placing heavy objects on top of it.
• Do not, except as described in this booklet, attempt to
disassemble any part of the child seat or change the way
the harness or vehicle's seat belts are used.
• Never use the harness adjuster strap to lift or carry this
child seat. Doing so could cause damage to harness
adjuster and webbing. Always carry this child seat by its
shell or tether straps.
