2009 Ford F250 Super Duty Regular Cab Owner's Manual - Page 219

Seating and Safety Restraints Tether strap attachment (rear SuperCab only) There are three loops of webbing just above the back of the rear seat (along the bottom edge of the rear window) in the SuperCab. These loops are to be used as both routing loops and anchor loops for up to three child safety seat tether straps. These straps may be secured below the back of the seat with rubber bands. To access, reach below the back of the seat and pull tether loop out of the rubber band securing it. Many tether straps cannot be tightened if the tether strap is hooked to the loop directly behind the child seat. To provide a tight tether strap: 1. Route the tether strap through the loop directly behind the child seat. 2. Attach the strap hook onto the loop behind an adjacent seating position. 219 2009 F-250/350/450/550 (f23) Owners Guide, 3rd Printing USA (fus)
