RSA (Road Sign Assist) *
The RSA system recognizes spe-
cific road signs using the camera
sensor and navigation system
(when data is available) to provide
information to the driver via the
multi-information display and
head-up 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.
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 neg ligent driving could
lead to an unexpected accident.

248 4-5. Using the driving support systems
LS500h_OM_OM50F42U_(U) When the camera sensor recognizes a
sign or information of a sign is available
from the navigation system , the sign
will be displayed on the multi-informa-
tion display.
 When the driving support system
information is selected, a maximum
of 3 signs can be displayed.
( → P.86)  When a tab other than the driving
support system information tab is
selected, only a recognized speed
limit sign or do not enter sign (when
notification is necessary) will be dis-
played. ( → P.86)
If signs other than speed limit signs are rec-
ognized, they will be displayed in an over-
lapping stack under th e current speed limit
sign.
The following types of ro ad signs are recognized.Non-official or recently introduced traffic signs may not be recognized.Indication on the multi-informa-

In the following situations, the RSA sys-
tem will alert the driver.
 When the vehicle speed exceeds
the speed warning threshold of the
speed limit sign displayed, the sign
display will be emphasized and a
buzzer will sound.
 When the RSA system recognizes a
do not enter sign and determines
that your vehicle has entered a
no-entry area, the displayed sign will
flash and a buzzer will sound.
Depending on the situation, traffic
environment (traffic direction, speed,
unit) may be detected incorrectly and a
warning display may not operate prop-
