Once the child safety seat has been installed using the safety belt, you
can attach the top tether strap.
Tether strap attachment
1. Route the child safety seat tether strap over the back of the seat.
For vehicles with adjustable head restraints, route the tether strap under
the head restraint and between the head restraint posts, other wise route
the tether strap over the top of the seatback. If the top of the safety seat
hits the head restraint, raise the head restraint to let the child seat fit
further rearward.
2. Locate the correct anchor for the selected seating position.
3. You may need to pull the seatback forward to access the tether
anchors. Make sure the seat is locked in the upright position before
installing the child seat. Refer to the Rear folding seat system with load
floor section in this chapter for information on how to operate the rear
seats.
4. Remove tether cover.
5. Clip the tether strap to the anchor as shown.
