Safety and Security Occupant safety The side impact air bags and window curtain air bags are not deployed in impacts which do not exceed the system's deployment threshold. Vehicles with OCS* only: The front passenger side impact air bag will not deploy if the OCS senses that the front passenger seat is empty and the front passenger seat belt is not fastened (latch plate is not inserted into the buckle). With an empty front passenger seat and the seat belt fastened (latch plate properly inserted into buckle) the front passenger side impact air bag will deploy independently of the empty seat. 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. Warning! G Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat covers may interfere with or prevent the deployment of the front side impact air bags or the rear side impact air bags*. Contact your authorized Mercedes-Benz Light Truck Center for availability. 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. 81
