RSA (Road Sign Assist)

∗

RSA recognizes specific road
signs using the camera sensor
and provides information to the
driver via the multi-information
display.

If the system judges that the vehicle is being driven over the speed
limit, performing prohibited actions, etc., in relation to the recognized
road signs, it alerts the driver using a warning display and warning
buzzer

: This setting needs to be customized.

Summary of function

camera sensor

WARNING

■

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.
Inappropriate or negligent driving could lead to an unexpected accident.

4-5. Using the driving support systems

After the camera sensor recognizes a sign, it is displayed on the multi-
information display when the vehicle passes the sign.
● When the driving assist system

information is selected, a maxi-
mum of 3 signs can be dis-
played. (

→P. 136)

● When other than the driving

assist system information is
selected, a speed limit sign, a
highway sign or an all canceled
sign can be displayed. 
(

→P. 136)

A no overtaking sign and a
speed limit sign with supple-
mental mark are not displayed.
However, if signs other than
speed limit signs are recog-
nized, they are mentioned in a
stack under the current speed
limit sign.
