To reduce follow-on accidents after a collision and facilitate the rescue of occupants, various measures can be adopted depending on the type and severity of the accident: the engine can be turned off automatically and the fuel supply cut off. The hazard warning lights and emergency interior lighting can be automatically activated, the side windows can be lowered a fraction if necessary and the door locks automatically released. The rescue guide developed by Mercedes-Benz as a precautionary measure for the rescue services is the final piece in the holistic safety philosophy.
