The RSA system recognizes specific road signs using the front camera to provide information to the driver via the display.
If the system judges that the vehicle is being driven over the speed limit, performing prohibited actions, etc.
according to the recognized road signs, it notifies the driver through a visual notification and notification buzzer.
WARNING
â– Before using the RSA
Do not rely solely upon the RSA system. RSA is a system which supports the driver by providing information, but it is not a replacement for a driver's own vision and awareness. Drive safely by always paying careful attention to the traffic rules.
