Safety and security Occupant safety Rdepending on whether the seat belt is in of the front air bags of the ETDs use Rindependently Rindependently leaning on armrests), the OCS may not be able to properly approximate the occupant's weight category. The passenger head-thorax air bag 1 will only deploy if the OCS senses that the passenger seat is occupied and the impact exceeds a preset deployment threshold. The head-thorax air bags are not deployed in side impacts which do not exceed the system's deployment threshold. Occupant Classification System The Occupant Classification System (OCS) automatically turns the passenger front air bag on or off based on the classified occupant weight category determined by weight sensor readings from the passenger seat. The system does not deactivate the passenger head-thorax air bag and the Emergency Tensioning Devices (ETDs). Occupants must sit with the seat belt properly fastened 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 i If your seat, including the 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. Both the driver and the passenger should always use the 5/ indicator lamp as an indication of whether or not the passenger is properly positioned. G Warning! If the 5/ indicator lamp illuminates when an adult or someone larger than a small individual is in the passenger seat, have the passenger re-position himself or herself in the seat until the 5/ indicator lamp goes out. In the event of a collision, the air bag control unit will not allow passenger front air bag deployment when the OCS has classified the passenger seat occupant as weighting as much as or less than a typical 12-monthold child in a standard child restraint or if the passenger seat is classified as being empty. When the OCS senses that the passenger seat occupant is classified as being up to or less than the weight of a typical 12-month-old child in a standard child restraint, the 5/ indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the passenger front air bag is deactivated. When the OCS senses that the passenger seat is classified as being empty, the 5/ indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the passenger front air bag is deactivated. When the OCS senses that the passenger seat occupant is classified as being heavier than the weight of a typical 12-month-old child seated in a standard child restraint or as being a small individual (such as a young teenager or a small adult), the 5/ indicator lamp will illuminate for approximately 6 seconds when the engine is started and then, depending on occupant weight sensor readings from the seat, remain illuminated or go out. With the 5/ indicator lamp illuminated, the 50
