*: If equipped
The RSA system recognizes
specific road signs using the
front camera and/or navigation
system (when speed limit infor-
mation is available) to provide
information to the driver via the

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.When the front camera recog-
nizes a sign and/or information
of a sign is available from the
navigation system, the sign will
be displayed on the multi-infor-
mation display.

When the driving support sys-
tem information is selected, a
maximum of 3 signs can be
displayed. ( P.97)

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 replace-
ment for a driver’s own vision and
awareness. Drive safely by
always paying careful attention to
the traffic rules.
