  • The hands-off warning message may appear late depending on road conditions. Always have your hands on the steering wheel while driving.
  • If the steering wheel is held very lightly the hands-off warning message may appear because Lane Following Assist may not recognize that the driver has their hands on the steering wheel.
  • If you attach objects to the steering wheel, the hands-off warning may not work properly.
