Safety and Security Occupant safety i The front air bags in this vehicle have been designed to inflate in two stages. This allows the air bag to have different rates of inflation that are based on the rate of relevant vehicle deceleration as assessed by the air bag control unit. On the front passenger-side, the front air bag deployment is additionally influenced by the passenger's weight category as identified by the Occupant Classification System (OCS) ( page 88). The lighter the front passenger side occupant, the higher the vehicle deceleration rate required for the second stage inflation of the air bag. The air bags will not deploy in impacts which do not exceed the system's deployment thresholds. You will then be protected by the fastened seat belts. The passenger front air bag will only be deployed if: the system, based on OCS weight sensor readings, senses that the front passenger seat is occupied the 59 indicator lamp in the center console is not lit ( page 92) the impact exceeds a preset deployment threshold Side impact air bags, window curtain air bags Warning! G The pressure sensors for side impact air bag control are located in the doors. Do not modify any components of the doors or door trim panels including, for example, the addition of door speakers. Improper repair work on the doors or the modification or addition of components to the doors creates a risk of rendering the side impact air bags inoperative or causing unintended air bag deployment. Work on the doors must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Light Truck Center. 78
