Abstract	Conditional automated driving (CAD) functions will be one of the key technologies promising comfort and efficiency in personal transportation. This work addresses the importance of a user-centered and variable Human-Machine-Interface (HMI) for CAD in consideration of different levels of trust. The question arises as to how the level of trust, presumably caused by system-experience with an automated system, modulates information needs. The variable HMI-concept was tested with a panel of 47 subjects in a driving simulator. Effects on system evaluation in terms of experience with a conditional automated system (between; system-inexperienced vs. system-experienced users) and the HMI (within; maximal-HMI with higher informational content vs. minimal-HMI with lower informational content) were examined. The gaze behaviour showed that the system-experienced users trusted the system more and monitored the system less frequently than the systeminexperienced users. System-experienced users focused on a non-driving-related task more often than system-inexperienced users. Even though, both user groups trusted the system more using the maximal-HMI than using the minimal-HMI, it is assumed, that long-term use will modulate the level of trust and the resulting information needs. This study supports the idea of adaptability of the HMI depending on the level of trust and the information needs.
