Tilt the right front seatback completely forward and the whole seat will slide forward. 2. Return the seatback to its original position after someone gets into the rear seat area. Then move the seat rearward until it locks. CAUTION: If the seatback isn't locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. CAUTION: If an easy entry right front seat isn't locked, it can move.
