multi-information display 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.
OWhen the system determines that the
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 canceled.
This warning also operates in the same
way when the driver continuously oper-
ates the steering wheel only a small
amount.
The buzzer also sounds even if the alert
type is set to “Steering wheel vibration”.
OWhen 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 driving around a
curve, warnings will occur earlier than
during straight-lane driving.
OWhen the system determines that the
driver is driving without holding the
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 driver is warned. Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes lon-
ger.
The buzzer also sounds even if the alert
type is set to “Steering wheel vibration”.
QVehicle sway warning function
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 simultane-
ously displayed on the multi-information
display.
Depending on the vehicle and road con-
ditions, the warning may not operate.
QWarning message
If the following warning message is dis-
played on the multi-information display
and the LTA indicator illuminates in
orange, follow the appropriate trouble-
shooting procedure. Also, if a different
warning message is displayed, follow
the instructions displayed on the screen.
O“LTA Malfunction Visit Your Dealer”
The system may not be operating prop-
erly. Have the vehicle inspected by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
O“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 turn
the LTA system back on.
O“LTA Unavailable at Current Speed”

3285-5. Using the driving support systems
The function cannot be used as the
vehicle speed exceeds the LTA opera-
tion range. Drive slower.
QCustomization
Function settings can be changed.
( P.184)
*: If equipped
RSA (Road Sign Assist)*
The RSA system recognizes
specific road signs using the
front camera and/or naviga-
tion system (when speed limit
information is available) to pro-
vide information to the driver
via the display.
If the system judges that the
vehicle is being driven over the
speed limit, performing prohib-
ited actions, etc. according to
the recognized road signs, it
notifies the driver through a
visual notification and notifica-
tion buzzer or steering wheel
vibration.
WARNING
QBefore using the RSA
Do not rely solely upon the RSA sys- tem. 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.

the sign display will be empha-
sized and a buzzer will sound.
When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys-
tem, 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 overtak-
ing sign is displayed on the multi-

WARNING
QBefore using dynamic radar
cruise control with full-speed range
ODriving safely is the sole responsi-
bility of the driver. Do not rely solely on the system, and drive safely by always paying careful attention to
your surroundings.
OThe dynamic radar cruise control
with full-speed range provides driv- ing assistance to reduce the driver’s burden. However, there are
limitations to the assistance pro- vided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be cor-
rectly detecting the vehicle ahead: P.342

D
E
• Conditions under which the vehicle- to-vehicle distance control mode may not function correctly: P.343
OSet the speed appropriately depending on the speed limit, traffic
flow, road conditions, weather con- ditions, etc. The driver is responsi-ble for checking the set speed.
OEven when the system is function-ing normally, the condition of the
preceding vehicle as detected by the system may differ from the con-dition observed by the driver.
Therefore, the driver must always remain alert, assess the danger of each situation and drive safely.
Relying solely on this system or assuming the system ensures safety while driving can lead to an
accident, resulting in death or seri- ous injury.
OSwitch the dynamic radar cruise control with full-speed range setting to off, using the cruise control main
switch when not in use.

3345-5. Using the driving support systems
WARNING
QCautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance provided by the system. Failure to do
so may cause an accident resulting in death or serious injury.
OAssisting the driver to measure fol-
lowing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol-
lowing distance between the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows careless or inattentive
driving, and it is not a system that can
assist the driver in low-visibility condi-
tions.
It is still necessary for driver to pay
close attention to the vehicle’s sur-
roundings.
OAssisting the driver to judge proper following distance
The dynamic radar cruise control with
full-speed range determines whether
the following distance between the
driver’s own vehicle and a designated
vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgement. Therefore, it
is absolutely necessary for the driver
to remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation.
OAssisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range does not include
functions which will prevent or avoid
collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any
possibility of danger, the driver must
take immediate and direct control of
the vehicle and act appropriately in
order to ensure the safety of all
involved.
QSituations unsuitable for dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con- trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control and could cause an accident resulting
in death or serious injury.
ORoads where there are pedestrians, cyclists, etc.
OIn heavy traffic
OOn roads with sharp bends
OOn winding roads
OOn slippery roads, such as those covered with rain, ice or snow
OOn steep downhills, or where there are sudden changes between sharp
up and down gradients
Vehicle speed may exceed the set
speed when driving down a steep hill.
OAt entrances to freeways and high- ways
OWhen weather conditions are bad enough that they may prevent the sensors from detecting correctly
(fog, snow, sandstorm, heavy rain, etc.)
