RSA (Road Sign  
*
Assist)  
*
: If equipped  
The RSA system detects  
specific road signs using  
the front camera and/or nav-  
igation system (when speed  
limit information is avail-  
able) and warns the driver  
via displays and buzzers.  
Multiple signs can be dis-  
played.  
Depending on the specifications of  
the vehicle, the number of dis-  
played signs may be limited.  
Operating conditions of sign

WARNING  
Signs will be displayed when the fol-  
lowing conditions are met:  
For safe use  
Driving safely is solely the  
responsibility of the driver. Pay  
careful attention to the sur-  
rounding conditions in order to  
ensure safe driving.  
The system has detected a sign

In the following situations, a dis-  
played sign may stop being dis-  
played:  
When a new sign has not been  
detected for a certain distance  
Do not rely solely upon the  
RSA. The RSA assists the  
driver by providing road sign  
information, but it is not a  
replacement for the driver’s own  
vision and awareness. Driving  
safely is solely the responsibility  
of the driver. Pay careful atten-  
tion to the surrounding condi-  
tions in order to ensure safe  
driving.  
When the system determines that  
the road being driven on has  
changed, such as after a left or  
right turn  
Situations in which the display  
function may not operate prop-  
erly  
In the following situations, the RSA  
system may not operate properly  
and may not detect signs or may  
display the incorrect sign. However,  
this does not indicate a malfunction.  
Situations in which the RSA  
should not be used  
When it is necessary to disable  
the system: P.184  
When a sign is dirty, faded, tilted  
or bent  
Situations in which the sys-  
tem may not operate properly  
When the contrast of an electronic  
sign is low  
Situations in which the sensors  
may not operate properly:  
P.188  
When all or part of a sign is hidden  
by a tree, utility pole, etc.  
When a sign is detected by the  
front camera for a short amount of  
time  
Display Function  
When the driving state (turning,  
changing lanes, etc.) is judged  
incorrectly  
When the front camera

When a sign is immediately after a  
freeway junction or in an adjacent  
lane just before merging  
Operating conditions of the  
notification functions  
Excess speed notification function  
When stickers are attached to the  
rear of a preceding vehicle  
This function will operate when the  
following condition is met:  
• A speed limit road sign is recog-  
nized by the system.  
When a sign similar to a system  
compatible sign is detected as a  
system compatible sign  
No entry notification function  
When a speed limit sign for a  
frontage road is within detection  
range of the front camera  
This function will operate when all of  
the following conditions are met:  
• More than one no entry road signs  
are recognized by the system  
simultaneously.  
• The vehicle is passing between no  
entry road signs recognized by the  
system.  
When driving around a round-  
about  
When a sign intended for trucks,  
etc. is detected  
When the navigation system map  
data is out of date  
When the navigation system can-

ported  
not be used  
In this case, the speed limit signs  
displayed on the multi-information  
display and navigation system dis-  
play may differ.  
The following types of road  
signs can be displayed.  
However, non-standard or recently  
introduced traffic signs may not be  
displayed.  
Notification function  
In the following situations, the  
RSA system will output a warn-  
ing to notify the driver.  
If the vehicle speed exceeds  
the speed warning threshold  
of the speed limit sign dis-  
played on the display, the sign  
display will be emphasized  
and a buzzer will sound.

(Canada)  
When the RSA system  
detects a do not enter sign  
and determines that the vehi-  
cle has entered a no-entry  
area, the do not enter sign  
displayed on the display will  
flash and a buzzer will sound.
