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.

2394-5. Using the driving support systems
LS500_OM_OM50F54U_(U) 4
Driving 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.76)  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.76)
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-

tem
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-
erly. ■

The Blind Spot Monitor is a system
that uses rear side radar sensors
installed on the inner side of the
rear bumper on the left and right
side to assist the driver in confirm-
ing safety when changing lanes. WARNING■
Cautions regarding the use of the sys-
tem
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
The Blind Spot Monitor is a supplemen-
tary function which alerts the driver that a
vehicle is in a blind spot of the outside
rear view mirrors or is approaching rap-
idly from behind into a blind spot. Do not
overly rely on the Blind Spot Monitor. As
the function cannot judge if it is safe to
change lanes, over reliance could lead to
an accident resulting in death or serious
injury.
As the system may not function correctly
under certain conditions, the driver’s own
visual confirmation of safety is necessary.
