■Setting procedure
 P.94
■Automatic turn-off of RSA sign 
display
In the following situations, displayed 
speed limit sign and/or do not enter 
signs will stop being displayed auto-
matically:
●No sign has been recognized for a 
certain distance.
●The road changes due to a left or 
right turn, etc.
In the following si tuations, stop and 
yield signs will stop being displayed 
automatically:
●The system determines that your 
vehicle has passed the sign.
●The road changes due to a left or 
right turn, etc.
■Conditions in which the func-
tion may not operate or detect 
correctly
In the following situations, RSA 
does not operate normally and may 
not recognize signs, display the 
incorrect sign, etc. However, this 
does not indicate a malfunction.
●The front camera is misaligned 
due to a strong impact being 
applied to the sensor, etc.
●D i r t ,  s n o w ,  s t i c k e r s ,  e t c .  a r e  o n  t h e  
windshield near the front camera.
●In inclement weather such as 
heavy rain, fog, snow or sand 
storms
●Light from an oncoming vehicle,  the sun, etc. ente
rs the front cam-
era.
●The sign is dirty, faded, tilted or 
bent, and if an electronic sign, the 
contrast is poor.
●All or part of the  sign is hidden by 
the leaves of a tree, a pole, etc.
●The sign is only visible to the front 
camera for a short amount of time.
●The driving scene (turning, lane 
change, etc.) is judged incorrectly.
●If a sign not appropriate for the 
currently traveled lane, but the 
sign exists directly after a freeway 
branches, or in an adjacent lane 
just before merging.
●Stickers are attached to the rear 
of the preceding vehicle.
●A sign resembling a system com-
patible sign is recognized.
●Side road speed signs may be 
detected and displayed (if posi-
tioned in sight of the front camera) 
while the vehicle i s traveling on 
the main road.
●Roundabout exit road speed signs 
may be detected and displayed (if 
positioned in si ght of the front 
camera) while t raveling on a 
roundabout.
●The front of the vehicle is raised or 
lowered due to the carried load.
●The surrounding brightness is not 
sufficient or changes suddenly.
●When a sign inte nded for trucks, 
etc. is recognized.
●The speed information displayed 
on the meter and on the naviga-
tion system may be  different due 
to the navigation system using 
map data.
■Speed limit sign display
If the engine switch was last turned 
off while a speed limit sign was dis-
played on the multi-information dis-
play, the same sign displays again 
when the engine switch is turned to 
ON.

Driving
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed 
appears
When a vehicle is detected runni ng ahead of you, the system automatically 
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the  brakes (the stop lights will come on at this 
time). The system will respond to changes i n the speed of the vehicle 
ahead in order to maintain the ve hicle-to-vehicle distance set by the driver. 
Approach warning warns you when  the system cannot decelerate suffi-
ciently to prevent your vehicle  from closing in on the vehicle  ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is 
stopped by system control). Afte r the vehicle ahead starts off, pressing the 
“+RES” switch or depressing the  accelerator pedal (start-off operation) will 
resume follow-up cruising. If the start-off operation is not performed, system 
control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identifi cation of what is an overtaking lane may be deter-
mined solely based on  the location of the steering wheel in the  vehicle (left 
side driver position versus righ t side driver position.) If the vehicle is driven 
to a region where the overtaking lane is on a different side fr om where the 
vehicle is normally driven, the v ehicle may accelerate when the turn signal 
lever is operated in the opposite direction to the overtaking l ane (e.g., if the 
driver normally operates the vehicle in a region where the over taking lane is 
to the right but then drives to  a region where the overtaking l ane is to the 
left, the vehicle may accelerate  when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower 
than the set speed
The system accelerates until the  set speed is reached. The system then 
returns to constan t speed cruising.
