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.
Vehicles with 7-inch display:
When the driving support sys-
tem information is selected, a

 Vehicles with 7-inch display:
When a tab other than the
driving support system infor-
mation is selected, the follow-
ing types of road signs will be
displayed. ( P.87)
• Speed limit sign
• Do Not Enter sign (when notifica-
tion is necessary)
RSA (Road Sign
Assist)*
The RSA system recognizes
specific road signs using
the front camera and/or nav-
igation system (when speed
limit information is avail-
able) to provide information
to the driver via the display.
If the system judges that the
vehicle is being driven over
the speed limit, performing
prohibited actions, etc.
according to the recog-
nized road signs, it notifies
the driver through a visual
notification and notification
buzzer.
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.
Indication on the
multi-information display

2624-5. Using the driving support systems
If signs other than speed limit signs
are recognized, they will be dis-
played in an overlapping stack
under the current speed limit sign.
The following types of road
signs, including electronic signs
and blinking signs, are recog-
nized.
A non-official or a recently intro-
duced traffic sign may not be recog-
nized.
In the following situations, the
RSA system will notify the
driver.
 When the vehicle speed
exceeds the speed notifica-
tion threshold of the speed
limit sign displayed, the sign
display will be emphasized
and a buzzer will sound.
 When the RSA system recog-
nizes 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, a
notification function may not
operate properly.
■Setting procedure
 P.92, 102
■Automatic turn-off of RSA sign
display
In the following si tuations, a dis-
played speed limit sign and/or do
not enter sign will stop being dis-
played automatically:
●No sign has been recognized for a
certain distance.
●The road changes due to a left or
right turn, etc.
In the following situations, stop and
yield signs will stop being displayed
automatically:

tor)*
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
confirming safety when
changing lanes.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. Always drive safely,
taking care to o bserve your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a v ehicle is in a
blind spot of the outside rear view
mirrors or is approaching rapidly
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 seri-
ous injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
