lane centering function does not oper-
ate.
In situations where the white (yellow)

*: If equipped
RSA (Road Sign Assist)*
The RSA system recognizes
specific road signs using the
front camera and/or naviga-
tion system (when speed limit
information is available) to pro-
vide information to the driver
via the display.
If the system judges that the
vehicle is being driven over the
speed limit, performing prohib-
ited actions, etc. according to
the recognized road signs, it
notifies the driver through a
visual notification and notifica-
tion buzzer or steering wheel
vibration.
WARNING
■Before using the RSA
Do not rely solely upon the RSA sys- tem. 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.
