Seating and Safety Restraints
The tether strap anchors in your vehicle are in the following positions
(shown from top view):
• F-Series Regular Cab
• F-Series Crew Cab
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 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, otherwise 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.
