Depending on the vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv-
ing around a curv e, warnings will
occur earlier than during straight-
lane driving.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
steering wheel assist of the steer-
ing assist function is operating.
If the driver continues to keep their
hands off of the steering wheel and
the steering wheel assist is operat-
ing, the buzzer sounds and the
driver is warned. Each time the
buzzer sounds, the continuing time
of the buzzer becomes longer.
The buzzer also sounds even if the
alert type is set to .
■Vehicle sway warning function
When the system de termines 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 sim ultaneously dis-
played on the multi-information dis-
play.
Depending on the vehicle and road
conditions, the warning may not
operate.
■Warning message
If the follo wing warning message is
displayed on the multi-information display and the LTA indicator illumi-
nates in orange, follow the appropri-
ate troubleshooting procedure. Also,
if a different warning message is
displayed, follow the instructions
displayed on the screen.
●“LTA Malfunction Visit Your
Dealer”
The system may not be operating
properly. Have the vehicle inspected
by your Toyota dealer.
●“LTA Unavailable”
The system is temporarily canceled
due to a malfunction in a sensor
other than the front camera. Turn
the LTA system off, wait for a little
while, and then tu rn the LTA system
back on.
●“LTA Unavailable at Current
Speed”
The function cannot be used as the
vehicle speed exceeds the LTA
operation range. Drive slower.

*: If equipped
The RSA system recognizes
specific road signs using the
front camera and/or navigation
system (when speed limit infor-
mation is available) to provide
information to the driver via the
display.
When the front camera recog-
nizes a sign and/or information
of a sign is available from the
navigation system, the sign will be displayed on the multi-infor-
mation display.

When the driving support sys-
tem information display is
selected, a maximum of 3
signs can be displayed.
( P.100)
 When a tab other than the
driving support system infor-
mation is selected, the follow-
ing types of road signs will be
displayed. ( P.100)
• Speed limit sign
• Do Not Enter sign (when notifica-
tion is necessary)
If signs other than speed limit signs
are recognized, they will be dis-
played in an overlapping stack
under the current speed limit sign.

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 replace-
ment for a driver’s own vision and
awareness. Drive safely by
always paying careful attention to
the traffic rules.

Driving
The following types of road
signs, including electronic signs
and blinking signs, are recog-
nized.
A non-official or a recently intro-
duced traffic sign may not be recog-
nized.
In the following situations, the
RSA system will notify the
driver.
 When the vehicle speed
exceeds the speed notifica-
tion threshold of the speed
limit sign displayed, the sign
display will be emphasized
and a buzzer will sound.
 When the RSA system recog-
nizes a do not enter sign and
determines that your vehicle
has entered a no-entry area,
the displayed sign will flash
and a buzzer will sound. Depending on the situation, a
notification function may not
operate properly.
■Setting procedure
1 Press or of the meter
control switches and select .
2 Press or of the meter
control switch es and select
“ RSA”, then press .
■Automatic turn-off of RSA sign
display
In the following si tuations, a dis-
played speed limit sign and/or do
not enter sign will stop being dis-
played automatically:
●No sign has been recognized for a
certain distance.
●The road changes due to a left or
right turn, etc.
In the following situations, stop and
yield signs will stop being displayed
automatically:
●The system determines that your
vehicle has passed the sign.
●The road changes due to a left or
right turn, etc.
■Conditions in which the func-
tion may not operate or detect
correctly
In the following si tuations, RSA
does not operate normally and may
not recognize 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, sticker s, etc., are on
the windshield near the front cam-
era.
●In inclement weather such as
heavy rain, fog, snow or sand
storms

off while a speed limit sign was dis-
played on the multi-information dis-
play, the same sig n displays again
when the power switch is turned to

Driving
In vehicle-to-vehicle distance
control mode, the vehicle auto-
matically accelerates, deceler-
ates and stops to match the
speed changes of the preceding
vehicle even if the accelerator
pedal is not depressed. In con-
stant speed control mode, the
vehicle runs at a fixed speed.

WARNING
■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole
responsibility of the driver. Do
not rely solely on the system,
and drive safely by always pay-
ing careful attent ion to your sur-
roundings.
●The dynamic radar cruise con-
trol with full-speed range pro-
vides driving assistance to
reduce the driver’s burden.
However, there are limitations to
the assistance provided.
Read the followin g conditions
carefully. Do not overly rely on
this system and always drive
carefully.

control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehi cle is driven to a
region where the overtaking lane is on a different side from wh ere the vehi-
cle is normally driven, the vehicle may accelerate when the tur n signal lever
is operated in the opposite direction to the overtaking lane (e .g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the
vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constan t speed cruising.
1Press the cruise control main
switch to activate the cruise
control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display. Press the switch
again to deactivate the cruise con-
trol.
If the cruise cont rol main switch is
pressed and held for 1.5 seconds
or more, the syste m turns on in
constant speed control mode. (
