WARNING:
Never do this.
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Never put a rear-facing child restraint in the
right front seat. Secure a rear-facing child restraint
in a rear seat. It is also better to secure a
forward-facing child restraint in a rear seat. If you
must secure a forward-facing child restraint in the
right front seat, always move the front passenger
seat as far back as it will go.

Q: What are the different types of add-on child
restraints?
A: Add-on child restraints, which are purchased by the
vehicle's owner, are available in four basic types.
Selection of a particular restraint should take into
consideration not only the child's weight, height, and
age but also whether or not the restraint will be
compatible with the motor vehicle in which it will
be used.
