Safety and Security Occupant safety Window curtain air bags The window curtain air bags are deployed: on the impacted side of the vehicle in impacts exceeding a preset deployment threshold independently of the front air bags regardless of whether the front-passenger seat is occupied in certain vehicle rollovers 1 Window curtain air bag When deployed, the window curtain air bags 1 are designed to provide increased protection for the head (but not the chest or arms) of the occupants on the side of the vehicle on which the impact occurs. The window curtain air bags fill up the area indicated by the arrows. The side window curtain air bags are not deployed in impacts which do not exceed the system's deployment threshold. 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 The system does not deactivate the front passenger side impact air bag, the window curtain 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. 41
