Third Row Seat - SUV Do not secure a child restraint in the right front passenger's position, or in the second row outboard positions of a SUT model, if a national or local law requires that the top tether be attached, or if the instructions that come with the child restraint say that the top tether must be attached. There is no place to attach the top tether in this position. Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. See Where to Put the Restraint on page 1-42 for additional information. Second Row Seats - SUT For SUV models with third row seating, the top tether anchor is located at the bottom rear of the seat cushion for the seating position in the third row. 1-47
