Safety Belt Extender

If the vehicle's safety belt will fasten around you, you
should use it.
But if a safety belt isn't long enough to fasten, your
dealer will order you an extender. It's free. When you go
in to order it, take the heaviest coat you will wear, so
the extender will be long enough for you. The extender
will be just for you, and just for the seat in your
vehicle that you choose. Don't let someone else use it,
and use it only for the seat it is made to fit. To wear
it, just attach it to the regular safety belt.

Child Restraints

Older Children

Older children who have outgrown booster seats should
wear the vehicle's safety belts.
If you have the choice, a child should sit in a seating
position that has a lap-shoulder belt to get the additional
restraint a shoulder belt can provide.
