Modern cars offer an increasingly powerful Multimedia environment. While also the potential for an application as Human Computer Interface (HCI) is growing, in this paper we concentrate on already existing possibilities for their use as Computer-HumanInterface (CHI) to communicate system security related information to the driver. After identifying the Intrusion Detection approach from desktop IT as a promising supplemental measure for the IT security of future automotive systems and successfully testing it in practice, in this paper we investigate about how such an automotive Intrusion Detection System (IDS) could communicate security-related information to the driver. We propose an adaptive dynamic concept to address the frequently changing environmental conditions in the automotive domain and discuss it using three exemplarily selected scenarios.
