Seating and Safety Restraints
Attach the tether strap afterward, if included with the child seat. Refer
to Recommendations for attaching safety restraints for children in
this chapter.
Attaching child safety seats with tether straps
Many forward-facing child safety seats include a tether strap which
extends from the back of the child safety seat and hooks to an anchoring
point called the top tether anchor. 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, or to obtain a
longer tether strap if the tether strap on your safety seat does not reach
the appropriate top tether anchor in the vehicle.
The rear seats of your vehicle are equipped with built-in tether strap
anchors located behind the seats as described below.
The tether strap anchors in your vehicle are in the following positions
(shown from top view):
• 40/40 second row seats and
third-row passenger side
• 60/40 second row seats and
third-row passenger side
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.
