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) lane lines or a course*. (When a 
white [yellow] line or course* is recognized on only one side, the system

■ 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. ( P. 358) 
■ Yaw assist function 
● Depending on the vehicle speed, lane departure situation, road conditions, 
etc., the driver may not feel the func tion is operating or the function may not 
operate at all. 
● The yaw assist of the function is overridden by the driver’s steering wheel 
operation. 
● Do not attempt to test the operation of the yaw assist function. 
● A sound may be heard from the engine compartment when the brake pedal 
is depressed, when the yaw assist function is operating. This sound does 
not indicate that a malfunction is occurred in the LDA system. 
■ Lane departure alert function 
● The warning buzzer may be difficult to hear due to external noise, audio 
playback, etc. 
● If the edge of the course* is not clear or straight, the lane departure alert 
function may not operate. 
● Do not attempt to test the operation of the lane departure alert function.
*: Boundary between asphalt and the side of the road, such as grass, soil, 
or a curb 
■ Vehicle sway warning function 
Depending on the vehicle and road conditions, the warning may not operate. 
When the system determines that the 
vehicle is swaying while the vehicle sway 
warning function is operating, a buzzer 
sounds and a warning message urging
the driver to rest and the symbol shown in 
the illustration are simultaneously dis- 
played on the multi-information display.

■ Warning message 
If the following warning message is displayed on the multi-information dis- 
play, and the LDA indicator illuminates in yellow, follow the appropriate trou-
bleshooting procedure. Also, if a different warning message is displayed, 
follow the instructions displayed on the screen. 
● “LDA Malfunction Visit Your Dealer” 
The system may not be operating properly. Have the vehicle inspected by 
any authorized Toyota retailer or Toyota  authorized repairer, or any reliable 
repairer. 
● “Lane Departure Alert Unavailable” 
• The system is temporarily canceled due to a malfunction in a sensor 
other than the front camera. Turn the LDA system off, wait for a little
while, and then turn the LDA system back on. 
• The system is temporarily unavaila ble as the vehicle repeatedly departs 
from its lane or course* in a short period of time. Turn the engine switch
to the “LOCK” position (vehicles without smart entry & start system) or off 
(vehicles with smart entry & start system), and then turn it to the “ON” 
position (vehicles without smart entry & start system) or IGNITION ON
mode (vehicles with smart entry & start system) again. 
● “LDA Unavailable at Current Speed” 
The function cannot be used as the vehicle speed exceeds the LDA opera- 
tion range. Drive slower.
*: Boundary between asphalt and the side of the road, such as grass, soil, or 
a curb 
■ Customization 
Function settings can be changed.

RSA (Road Sign Assist)
The RSA system recognizes spe- 
cific road signs using the front 
camera and/or navigation system 
(when data is available) to provide 
information to the driver via the 
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.
: If equipped
Summary of function
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.

When the front camera recognizes a sign, and/or information of a sign 
is available from the navigation system, the sign will be displayed on 
the multi-information display. 
● When the driving support sys- 
tem information is selected, a 
maximum of 3 signs can be dis- 
played. ( P. 151) 
● When a tab other than the driv- 
ing support system information 
is selected, only a recognized 
speed limit sign, a no-entry
sign* (when notification is nec- 
essary), expressway sign, high- 
way sign or Residential area
sign will be displayed.  
( P. 151)
A no overtaking sign and a speed limit sign with supplemental mark are 
not displayed. However, if signs other than speed limit signs are recog- 
nized, they will be displayed in an overlapping stack under the current
speed limit sign.

In the following situations, the RSA system will alert the driver. 
● When the vehicle speed exceeds the speed warning threshold of 
the speed limit sign displayed, the sign display will be emphasized 
and a buzzer will sound. 
● When the RSA system recognizes a no-entry sign and detects that 
the vehicle has entered a no-entry area based on the map informa-
tion of the navigation system, the no-entry sign flashes and a 
buzzer will sound. (For vehicles with navigation system) 
● If it is detected that your vehicle is overtaking when a no overtaking 
sign is displayed on the multi-information display, the displayed sign
will flash and a buzzer will sound. 
Depending on the situation, traffic environment (traffic direction, 
speed unit) may be detected incorrectly and a warning indication may 
not operate properly.
■ Setting procedure 
Setting for “RSA” in   of the multi-information display is set to “On”  
( P. 151) 
■ 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 front camera is misaligned due to a strong impact being applied to the 
sensor, etc. 
● Dirt, snow, stickers, etc. are on the 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. enters the front camera. 
● 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.
