A vehicular display system can project optical images onto different areas on a front windshield in accordance with the effective height of a driver's eyes. The display system includes an image source and a mirror, either of which can be tilted manually and/or automatically. The mirror reflecting an image from the image source onto the inside of the windshield at an angle suitable for reflection toward the driver's eyes and at a height on the windshield fully within the driver's field of view. An electrically controlled seat can provide seat position and inclination signals for use in automatically adjusting the display height. In addition, a memory may hold manually entered display-height information to expedite readjustment of the display height in cases where more than one driver uses the vehicle.
