severe or even fatal injury to other persons; if they get out of the vehicle, they could injure
themselves when doing so or be seriously or
even fatally injured by any passing traffic.

direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and a child could be burned on these
parts. G

ment unless they are firmly secured in place.
