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.

1. Route the child safety seat tether strap over the back of the seat and
under the head restraint.
For vehicles with adjustable head restraints, route the tether strap under
the head restraint and between the head restraint posts, otherwise route
the tether strap over the top of the seatback.
2. Locate the correct anchor for the selected seating position.
• You may need to pull the seatback forward to access the tether
anchors. Make sure the seatback is locked in the upright position
before installing the child seat.
3. Clip the tether strap to the anchor as shown.
• Regular Cab passenger and center
seats (located on back panel)
If the tether strap is clipped
incorrectly, the child safety seat may
not be retained properly in the
event of a collision.
4. Tighten the child safety seat
tether strap according to the
manufacturer’s instructions.
If the safety seat is not anchored
properly, the risk of a child being
injured in a collision greatly
increases.
