RSA (Road Sign Assist)
RSA recognizes specific road
signs using the camera sensor
and provides information to the
driver via the main display or
multi-information 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 negligent driving could lead to an unexpected accident.

PRIUS +_OM_OM47D30E_(EE)
After the camera sensor recognizes a sign, it is displayed on the main
display or multi-information display when the vehicle passes the sign.
●When the driving assist system
information is selected in multi-
information display, a maximum
of 2 signs can be displayed.
(P. 296)
●When other than the driving
assist system information is
selected, speed limit sign or an
all canceled sign can be dis-
played. (P. 296)
A no overtaking sign and a speed
limit sign with supplemental mark
are not displayed. However, if
signs other than speed limit signs
are recognized, they are men-
tioned in a stack under the current
speed limit sign.
Indication on the multi-information display

2964-5. Using the driving support systems
PRIUS +_OM_OM47D30E_(EE)
The following types of road signs, including electronic signs and blink-
ing signs, are recognized.
A non-official (not meeting the Vienna Convention) or a recently introduced
traffic sign may not be recognized.
*: If the turn signal indicator is not operated when changing lanes, the mark
does not display.

In the following situations, the RSA system alerts the driver using a
warning display.
●When the vehicle speed exceeds the speed warning threshold
applied to the speed limit of the sign displayed on the main display
or multi-information display, the sign color becomes inverted.
●If it is detected that your vehicle is overtaking when a no overtaking
sign is displayed on the multi-information display, the sign flashes.
Depending on the situation, traffic environment (traffic direction,
speed, unit) may be detected incorrectly and a warning display may
not operate properly.
■Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
●A new sign is not recognized for a certain distance.
●The road changes due to a left or right turn, etc.
■Conditions in which the function may not operate or detect correctly
In the following situations, RSA does not operate normally and may not rec-
ognize signs, display the incorrect sign, etc. However, this does not indicate a
malfunction.
●The camera sensor is misaligned due to a strong impact being applied to
the sensor, etc.
●Dirt, snow, stickers, etc., are on the windshield near the camera sensor.
●In inclement weather such as heavy rain, fog, snow or sand storms
●Light from an oncoming vehicle, the sun, etc., enters the camera sensor.
●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 camera sensor for a short amount of time.
●The driving scene (turning, lane change, etc.) is judged incorrectly.
●Even if it is a sign not appropriate for the currently traveled lane, such a 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 compatible sign is recognized.
●The vehicle is driven in a country with a different direction of traffic.
●Side road speed signs may be detected and displayed (if positioned in sight
of the camera sensor) while the vehicle is traveling on the main road.
Warning display

2984-5. Using the driving support systems
PRIUS +_OM_OM47D30E_(EE)●Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the camera sensor) while traveling on a roundabout.
●The speed information displayed on the meter and that displayed on the
navigation system may be different due to the navigation system using map
data.
■Turning the system on/off
■Speed limit sign display
If the power switch was last turned off while a speed limit sign was displayed
on the main display or multi-information display, the same sign displays again
when the power switch is turned to ON mode.
■Customization
Setting (e.g. speeding warning threshold) can be changed. (Customizable
feature: P. 539) Select on the settings display
(P. 126)

Dynamic radar cruise control
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates and decelerates to match the speed changes of the pre-
ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.
● Vehicle-to-vehicle distance control mode (P. 302)
● Constant speed control mode (P. 308)

cator will come on and a message
will be displayed on the multi-infor-
mation display.
Press the button again to deacti-
vate the cruise control.
If the “ON-OFF” button is pressed
and held for 1.5 seconds or more,
the system turns on in constant
speed control mode. ( P. 308)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 50 km/h
[30 mph]) and push the lever
down to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the lever is released becomes the
set speed.
