RSA recognizes specific road signs using the front sensor and pro-
vides information to the driver via the 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.

UK AURIS_HV_HB_EE (OM12K47E)
After the front sensor recognizes a sign, it is displayed on the multi-
information display when the vehicle passes the sign.
●When the driving assist system
information is selected, a maxi-
mum of 3 signs can be dis-
played. ( →P. 106)
● When other than the driving
assist system information is
selected, a speed limit sign or
an all canceled sign can be dis-
played. ( →P. 106)
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.

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 intro-
duced traffic sign may not be recognized.
*1: A speed limit sign with a value greater than 130 may not be recognizedand a wrong speed limit may be displayed.
*2: If the turn signal indicator is not operated when changing lanes, the markdoes 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 multi-informa-
tion 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.
Depending on the situation, the driving behavior (turning, lane change, etc.)
may be detected incorrectly and the automatic turn-off may not operate
properly.

■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 front sensor is misaligned due to a strong impact being applied to the
sensor, etc.
● Dirt, snow, stickers, etc., are on the windshield near the front sensor.
● In inclement weather such as heavy rain, fog, snow or sand storms
● Light from an oncoming vehicle, the sun, etc., enters the front sensor.
● The sign is small, 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 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 front sensor) while the vehicle is traveling on the main road.
● Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the front sensor) while traveling on a roundabout.
● The speed information displayed on the meter and that displayed on the
Navigation system (if equipped) may be different due to the Navigation sys-
tem using map data.

When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set unit of the meter, it is neces-
sary to change the set unit of the meter. Adjust the set unit of the meter to the
speed unit of signs in the current location. ( →P. 566)
■ 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 multi-information display, the same sign displays again when the
power switch is turned to ON mode.
■ When “Check RSA system.” is displ ayed on the multi-information dis-
play
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped profes-
sional immediately.
■ Customization
The settings for warning display, warning buzzer
*, speeding warning thresh-
old, etc., can be changed. (Customizable feature: →P. 566)
*: If a speed limit with supplemental mark is exceeded, the warning buzzer
does not operate. Select on the settings display
(→ P. 112)
Press the enter/set switch on the meter
control switches.
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.
