Jeep 2008 Liberty - Manual (Page 78)

To attach a child restraint tether strap:
Route the tether strap over the seat back and attach the
hook to the tether anchor located on the back of the seat.
For the outboard seating positions, route the tether
underneath the headrest and attach the hook to the tether
anchor located on the back of the seat.
WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
