■If “Check LDA system.” is displayed on the multi-information display
If the LDA indicator does not come on when the LDA switch is pressed to turn
the system on, the system may be malfunctioning. Have the vehicle
inspected by any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional immediately.
■ Operation conditions
This function operates when all of the following conditions are met.
● LDA is turned on.
● Vehicle speed is approximately 50 km/h (32 mph) or more.
● System recognizes white (yellow) lines.
● Width of traffic lane is approximately 3 m (9.8 ft.) or more.
● Turn signal lever is not operated.
● Vehicle is driven on a straight road or around a gentle curve with a radius of
more than approximately 150 m (492 ft.).
● No system malfunctions are detected. (P. 491)
■ Temporary cancellation of functions
When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation
of the function is automatically restored.
■ Lane departure alert function
The warning buzzer may be difficult to hear due to external noise, audio play-
back, etc.
■ White (yellow) lines are only on one side of road
The LDA system will not operate for the side on which white (yellow) lines
could not be recognized.
■ After the vehicle has been parked in the sun
The LDA system may not be available and a warning message may be dis-
played for a while after starting off. When the temperature in the cabin
decreases and the temperature around the front sensor ( P. 248) becomes
suitable for its operation, the system will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane mark-
ers could not be recognized.

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 th at 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.

Driving
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 Vienn a Convention) or a recently intro-
duced traffic sign may not be recognized.

Driving
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 si gn 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-info rmation 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.

Driving
■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 displayed 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.
