If a :H-type

its anchorage points, the restraint won't be
able to protect a child sitting there. In a crash,
the child could be seriously injured or killed.

properly installed using the anchorage points,
or use the vehicle's safety belts to secure the
restraint. See "Securing a Child Restraint in a
Rear Outside Seat Position" in the Index for
information on how to secure a child restraint
in your vehicle using the vehicle's safety belts.
