Recently, many kinds of information are provided to drivers because of the improvement of ADAS (Advanced Driver Assistance System). Amount of the information in vehicle cockpit seems to be increased due to the development of automobile technology such as autonomous driving. It is very important to consider the design of appropriate auditory information to avoid overlooking visual information cues. In this paper, we examined the effect of localization control of warning sounds to determine the direction of visual information using a driving simulator. The number of overlooked visual information cues and subjective task load were significantly decreased by the localization control in comparison with the no-localization and no-sound conditions. A driver could recognize the direction of visual information without removing their gaze from frontal view so that a driver also could find the visual information rapidly and accurately, and could watch the frontal view more long duration. It led to steady driving performance such as steering and speed control. In contrast, these effects were diminished if the timbre of the signal was difficult to localize.
