A vehicular driver assist system includes a sensor disposed at a vehicle and a display disposed at the vehicle and viewable by a driver of the vehicle. An electronic control unit (ECU) includes a processor for processing sensor data captured by the sensor to detect presence of objects in the field of view of the sensor. The vehicular driver assist system, responsive to processing by the processor of sensor data captured by the sensor, determines presence of a driver of the vehicle and determines a position of the driver's head. The vehicular driver assist system, responsive to determining the position of the driver's head, adjusts an orientation of the display based on the determined position of the driver's head to increase visibility of the display for the driver.
