Safety and Security Occupant safety Occupant Classification System The Occupant Classification System (OCS) automatically turns the front passenger front air bag on or off based on the classified occupant weight category determined by weight sensor readings from the front passenger seat. i If your seat, including your trim cover and cushion needs to be serviced in any way, take the vehicle to an authorized Mercedes-Benz Center. Only seat accessories approved by Mercedes-Benz may be used. Warning! G i The system does not deactivate the head-thorax air bag and the emergency tensioning device. Occupants must sit properly belted in a position that is as upright as possible with their back against the seat backrest and feet on the floor to be correctly classified. If the occupant's weight is transferred to another object in the vehicle (e.g. by leaning on armrests), the OCS may not be able to properly approximate the occupant's weight category. Both driver and the front passenger should always use the 56 indicator lamp as an indication of whether or not the front passenger is properly positioned. If the 56 indicator lamp illuminates when an adult or someone larger than a small individual is in the front passenger seat, have the front passenger re-position himself or herself in the seat until the 56 indicator lamp goes out.
