Seating and Safety Restraints
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.
The tether anchors in your vehicle are located on the back of the front
seat cushion.
The tether strap anchors in your vehicle are in the following positions
(shown from top view):
Bucket seats
60/40 seats
WARNING: Attach the tether strap only to the appropriate
tether anchor as shown. The tether strap may not work
properly if attached somewhere other than the correct tether
anchor.
