CAUTION:
{
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.
