Make sure there is nothing between seat cushion and child seat and check installation of the child seat. Make sure no objects applying supplemental weight onto the seat are present. Make sure no objects which apply forces to the seat are present (e.g. objects such as books, briefcases etc. lodged behind or around the seat, head restraints pushing against roof etc.). The system may recognize such forces as supplemental weight. If the indicator lamp remains out, have the system checked as soon as possible at an authorized Mercedes-Benz Center. Do not transport a child on the front passenger seat until the system has been repaired. Read and observe messages in the multifunction display and follow corrective steps (Y page 305).
