  • the display device 13 is a display device mounted on the vehicle HV. Examples of the display device 13 include a combination meter, CID (Center Information Display), and HUD (Head-Up Display).
  • the notification instructing unit 719b is authenticated by the first authenticating unit 714, but when the authentication is not established by the second authenticating unit 715, unauthorized authentication using wireless communication is performed on the own vehicle. This is notified to the display device 13 when the user gets on the vehicle HV. The display device 13 that has received the notification causes the display device 13 to display that unauthorized authentication using wireless communication has been performed on the vehicle.
  • the notification instruction unit 719b may determine from the vehicle door opening / closing signal obtained from the body ECU 8, the signal from the seating sensor, and the like.
