RSA (Road Sign Assist)
The RSA system recognizes spe-
cific road signs using the front
camera and/or navigation system
(when speed limit information is
available) 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 re cognized
road signs, it notifies the driver through a visual notificatio n and notifi-
cation buzzer.

Do not rely solely upon the RSA system. RSA is a system which s upports
the driver by providing information, but it is not a replacemen t for a driver’s
own vision and awareness. Drive safely by always paying careful attention
