Seating and Safety Restraints
The rear seats of your vehicle are equipped with built-in tether strap
anchors located behind the seats as described below.
The tether anchors in your vehicle are located under a cover marked
with the tether anchor symbol (shown with title).
The tether strap anchors in your
vehicle are in the following positions
(shown from top view):
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.
Once the child safety seat has been installed, using either the safety belt,
the lower anchors of the LATCH system, or both, you can attach the top
tether strap.
If you install a child seat with rigid LATCH attachments, and have
attached the top tether strap to the proper top tether anchor, do not
tighten the tether strap enough to lift the child seat off the vehicle seat
cushion when the child is seated in it. Keep the tether strap just snug
without lifting the front of the child seat. Keeping the child seat just
touching the vehicle seat gives the best protection in a severe crash.
Perform the following steps to attach a child safety seat to the tether
anchor:
1. Route the child safety seat tether strap over the back of the seat.
For outboard seating positions, route the tether strap under the head
restraint and between the head restraint posts. For the center seating
position, route the tether strap over the top of the head restraint.
2. Locate the correct anchor for the
selected seating position.
