Push the spring on the hook near the
door and remove the special belt.
Put the belt away in a safe place in your
vehicle, so it won't fly around in a crash
and injure someone.
Remember to reattach the automatic
belt again, once the child restraint is
removed. Be sure it isn't twisted.
Larger Children
Children who have outgrown child
restraints should wear the vehicle's
safety belts.
If you have the choice, a child should sit
next to a window so the child can wear
a lap-shoulder belt and get the
additional restraint a shoulder belt can
provide.
Accident statistics show that children
are safer if they are restrained in the
rear seat. But they need to use the
safety belts properly.
Children who aren't buckled up can
be thrown out in a crash.
Children who aren't buckled up can
