safety seat may not be properly secured and the child may be
injured in a sudden stop or collision.
Attaching child safety seats with tether straps
Most new forward-facing child safety seats include a tether strap which
goes over the back of the seat and hooks to an anchoring point. Tether
straps are available as an accessory for many older safety seats. Contact
the manufacturer of your child seat for information about ordering a
tether strap.

anchors located behind the seats as described below.
The tether anchors in your vehicle are straps on the seatback.

vehicle are in the following positions
(shown from top view):
Attach the tether strap only to the appropriate tether anchor as

somewhere other than the correct tether anchor.
