An interior rearview mirror assembly for a vehicle includes a reflective element disposed at a housing. The housing and the reflective element are tandemly and pivotally adjustable about a mounting structure mounted at an interior portion of the vehicle to provide a desired rearward field of view to a driver of the vehicle. A user input is actuatable by the driver of the vehicle. A motorized actuator is operable responsive to actuation of the user input to tilt the reflective element and the housing in tandem about a horizontal axis. Responsive to actuation of the motorized actuator responsive to the user input, the motorized actuator tandemly tilts the reflective element and the housing about the horizontal axis to orientate an outermost front surface of the reflective element more towards the driver or more away from the driver.
