To assist you in locating the lower anchors, each seating position with lower anchors has two labels, near the crease between the seatback and the seat cushion. To assist you in locating the top tether anchors, the top tether anchor symbol is located on the cover. The top tether anchors are located under the covers on the rear seatback filler panel. Flip open the cover to access the anchors. Be sure to use an anchor located on the same side of the vehicle as the seating position where the child restraint will be placed. Do not secure a child restraint in a position without a top tether anchor 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. 2-45
