Risk of injury

To ensure that the automatic child seat rec-

objects (such as acushion) under the child
restraint system. The entire base of the child restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-

could lead to injuries.
