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

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.

3444-5. Using the driving support systems
HILUX_OM_OM0K375E_(EE)
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

mum of 3 signs can be dis-
played. ( P. 141)
● 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.
