Temporary cancelation 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. 245)
■ Steering assist function
●Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the function is operating or the function may not
operate at all.
● The steering control of the function is overridden by the drive r’s steering
wheel operation.
● Do not attempt to test the operation of the steering assist fun ction.
■ Lane departure alert function
●The warning buzzer may be difficult to hear due to external noi se, 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 aler t function.
*: Boundary between asphalt and the side of the road, such as gra ss, soil, or
a curb
■ Hands off steering wheel warning
●When the system determines that t he driver is driving without holding the
steering wheel while the system is operating
If the driver continues to keep their hands off of the steering wheel, the
buzzer sounds, the driver is warned and the function is temporarily can-
celed.
This warning also operates in the same way when the driver cont inuously
operates the steering wheel only a small amount.
● When the system determines that the vehicle may not turn and instead
depart from its lane while driving around a curve
Depending on the vehicle condition and road conditions, the war ning may
not operate. Also, if the system determines that the vehicle is driving
around a curve, warnings will occur earlier than during straight-lane driving.
In the following situations, a warning mes-
sage urging the driver
to hold the steering
wheel and the symbol shown in the illus-
tration are displayed on the multi-informa-
tion display to warn the driver. The
warning stops when the system deter-
mines that the driver holds the steering
wheel.
Always keep your hands on the steering
wheel when using this system, regardless
of warnings.

steering wheel while the steering wheel assist of the steering assist function
is operating.
If the driver continues to keep their hands off of the steering wheel and the
steering wheel assist is operating, the buzzer sounds and the d river is
warned. Each time the buzzer sounds, the continuing time of the buzzer
becomes longer.
■ Vehicle sway warning function
■ Warning message
If the following warning message is displayed on the multi-info rmation display
and the LDA indicator illuminates in yellow, follow the appropr iate trouble-
shooting procedure. Also, if a different warning message is displayed, follow
the instructions displayed on the screen.
● “Lane Departure Alert Malfunction Visit Your Dealer”
The system may not be operating properly. Have the vehicle insp ected by
your Toyota dealer.
● “Lane Departure Alert Unavailable”
The system is temporarily canceled due to a malfunction in a se nsor other
than the front camera. Turn the LDA system off, wait for a little while, and
then turn the LDA system back on.
● ”Lane Departure Alert Unav ailable at Current Speed”
The function cannot be used as the vehicle speed exceeds the LD A opera-
tion range. Drive slower.
● “Lane Departure Alert Unavai lable Below Approx 32MPH”
The LDA system cannot be used as the vehicle speed is less than approxi-
mately 32 mph (50 km/h). Drive the vehicle at approximately 32 mph
(50 km/h) or more.
■ Customization
Function settings can be changed.

When the system determines that the
vehicle is swaying while the vehicle sway
warning function is operating, a buzzer

RSA (Road Sign Assist)
The RSA system recognizes spe-
cific road signs using the front
camera 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 wa rning
buzzer.

Summary of function
WARNING
■ Before using the RSA
Do not rely solely upon the RSA system. RSA is a system which s upports
the driver by providing information, but it is not a replacemen t 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, the sign will be displayed
on the multi-information display.
● When the driving assist sys-
tems display is selected, a max-
imum of 2 signs can be
displayed. ( P. 117)
● When a tab other than the
driving assist systems display
is selected, only a recognized
speed limit sign or do not
enter sign (when notification is
necessary) will be displayed.
( P. 117)
If signs other than speed limit signs are recognized, they will be dis-
played in an overlapping stack under the current speed limit si gn.

The following types of ro ad signs are recognized.
A non-official or a recently introduced traffic sign may not be recognized.
In the following situations, the RSA syst em will alert the driver.
● When the vehicle speed exceeds the speed warning threshold of
the speed limit sign displayed, the sign display will be emphas ized
and a buzzer will sound.
● When the RSA system recognizes a do not enter sign and deter-
mines that your vehicle has ent ered a no-entry area, the displayed
sign will flash and a buzzer will sound.
Depending on the situation, traffic environment (traffic direct ion,
speed unit) may be detected incorrectly and a warning display m ay
not operate properly.

ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, t he vehicle runs at a fixed speed.
