Practical hints Vehicle status messages in the multifunction display Display messages Front Passenger Airbag Enabled See Operator's Manual Possible cause/consequence USA only: The front passenger front air bag is activated while driving even though a child, small individual, or object below the system's weight threshold is on the front passenger seat, or the front passenger seat is empty. Objects on the seat or forces acting on the seat may make the system sense supplemental weight. Possible solution X X X X X Stop the vehicle in a safe location as soon as possible. Engage the parking brake. Switch off the ignition. Open the front passenger door. Remove child and child restraint from front passenger seat and properly secure the child in rear seat employing the child restraint if necessary. Remove any other items from on and around the front passenger seat and make sure the parcel net on the back of the front passenger seat is empty. 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 and sense that an occupant on the front passenger seat is of a greater weight than actually present. Keep the seat unoccupied, close the front passenger door and switch on the ignition. X X X 310
