7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, if your child restraint has
a top tether, disconnect the top tether from the top

it go back all the way. The safety belt will move freely
again and be ready to work for an adult or larger
child passenger.
