Seats and Restraint System 1-29
{
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.
