• Steering assist function is not operating.
■Temporary cancelation of func-
tions
●When operation conditions are no
longer met, a function may be
temporarily canceled. However,
when the operation conditions are
met again, operation of the func-
tion is automatically restored.
( P.264)
●If the operation conditions
( P.264) are no longer met while
the lane centering function is
operating, the buzzer may sound
to indicate that the function has
been temporarily canceled.
■Steering assist function/lane
centering function
●Depending on the vehicle speed,
lane departure situation, road con-
ditions, etc., the driver may not
feel the function is operating or
the function may not operate at
all.
●The steering control of the func-
tion is overridden by the driver’s
steering wheel operation.
●Do not attempt to test the opera-
tion of the steering assist function.
■Lane departure alert function
●The warning buzzer may be diffi-
cult to hear due to external noise,
audio playback, etc.
●If the edge of the course* is not
clear or straight, the lane depar-
ture alert function may not oper-
ate.
●It may not be possi ble for the sys-
tem to determine i f there is a dan-
ger of a collision with a vehicle in
an adjacent lane.
●Do not attempt to test the opera-
tion of the lane departure alert
function.

the side of the road, such as grass, soil, or a curb
■Hands off steering wheel warn-
ing
In the following situations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illust ration are dis-
played on the multi-information dis-
play to warn the driver. The warning
stops when the sys tem determines
that the driver holds the steering
wheel. Always keep your hands on
the steering wheel when using this
system, regardless of warnings.
●When the system determines that
the driver is driving without hold-
ing 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 con-
tinuously operates the steering
wheel only a s mall 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 warning
may not operate. Also, if the system
determines that the vehicle is driv-
ing around a curve, 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

HIGHLANDER HV_Usteering 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.
■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 LT A 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.

tem information is selected, a
maximum of 3 signs can be
displayed. ( P.92, 102)
 When a tab other than the

RSA (Road Sign
Assist)*
The RSA system recognizes
specific 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 notifies the
driver using a notification
display and notification
buzzer.

■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.

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.

set speed when driving down a
steep hill.
●At entrances to freeways and
highways
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
