OCS categorizes the occupant on the frontpassenger seat by means of a weight sensor. The front-passenger front air bag is automatically deactivated for certain weight categories. The respective status can be recognized by the 45 indicator lamp. With the 45 indicator lamp illuminated, the front-passenger front air bag is deactivated.

For reasons of safety, Mercedes-Benz recommends that you only use seat accessories that have been approved by Mercedes-Benz. Both the driver and the front passenger should observe the 45 indicator lamp to determine whether or not the front passenger is positioned correctly. Z Safety
