Toyota RAV4 (XA50) 2019-2025 Owners Manual: RSA (Road Sign Assist)

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.
