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 42 indicator lamp. When the 42 indicator lamp is illuminated, the front-passenger front air bag is deactivated.
