A top strap anchor is located on the back of the rear seat frame above the floor for each rear seating position. In order to get to the anchors, you will have to fold the rear seatback(s). See Rear Seat Operation for information on folding the rear seatbacks.
Do not secure a child restraint in the right front passenger's position if a national or local law requires that the top strap be anchored, or if the instructions that come with the child restraint say that the top strap must be anchored. There is no place to anchor the top strap in this position.
