*: If equipped
When the front camera  detects a sign or information 
of a sign is available from the 
navigation system, the sign 
will be displayed on the dis-
p l a y.
 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 
display
Signs will be displayed when the fol-
lowing conditions are met:
●The system has detected a sign
In the following si tuations, a dis-
played sign may stop being dis-
played:
●When a new sign has not been 
detected for a certain distance
●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 situ ations, 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.
●When a sign is dirty, faded, tilted 
or bent
●When the contrast of an electronic 
sign is low
●When all or part of a sign is hidden 
by a tree, utility pole, etc.
●When a sign is d etected by the 
front camera for a short amount of 
time
●When the driving state (turning, 
changing lanes, etc.) is judged 
incorrectly
RSA (Road Sign 
Assist)*
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.
WARNING
■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.
●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.
■Situations in which the RSA 
should not be used

In this case, the speed limit signs 
displayed on the multi-information 
display and navigat ion system dis-
play may differ.
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.
 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.
■Operating conditions of the 
notification functions
●Excess speed notification function
This function will operate when the 
following condition is met:
• A speed limit road sign is recog- nized by the system.
●No entry notification function
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
