  • Your vehicle passes another vehicle.
  • Your vehicle changes lanes.
  • Your vehicle accelerates rapidly while a vehicle next to you starts at the same time.
  • A vehicle in the adjacent lane is two lanes away from you, or when a vehicle two lanes away moves into the next lane next to you.
  • A trailer or carrier is installed around the rear corner radar.
  • The bumper around the rear corner radar is covered by objects such as a bumper sticker, bumper guard, bicycle rack, etc.
  • The bumper around the rear corner radar is damaged, or the radar is out of position.
  • The height of your vehicle is lowered or raised due to heavy loads, incorrect tire pressure, etc.
