■Temporary cancellation of functions
When the operation conditions are no longer met, a function may be tempo-
rarily canceled. However, when the operation conditions are met again, oper-
ation of the function is automatically restored. ( P. 254)
■ Steering control 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.
■ Lane departure alert function
The warning buzzer may be difficult to hear due to external noi se, audio play-
back, etc.
■ Hands off steering wheel warning
If the driver continues to keep their hands off of the steering wheel, a warning
message and the symbol shown in the illustration are displayed on the multi-
information display, and the function is temporarily canceled.
This warning also operates in the same way when the driver continuously
operates the steering wheel only a small amount. Always keep yo ur hands on
the steering wheel when using this system, regardless of warnings.
Depending on the vehicle and road conditions, the warning may n ot operate.
■ Vehicle sway warning function
Depending on the vehicle and road conditions, the warning may n ot operate.
■ White (yellow) lines are on ly on one side of road
The LDA system will not operate for the side on which white (ye llow) lines
could not be recognized. When the system determines that the
driver has removed their hands from the
steering wheel while the steering control
function is operating, a warning message
urging the driver to hold the steering
wheel and the symbol shown in the illus-
tration are displayed on the multi-infor-
mation display.
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 messageDetails/Actions
“LDA Malfunction
Visit Your Dealer”
The system may not be operating
properly.
 Have the vehicle inspected at your
Toyota dealer.
“Front Camera Unavailable”
The operation conditions of the cam-
era sensor (temperature, etc.) are not
met.
When the operation conditions of
the camera sensor (temperature,
etc.) are met, the LDA system will
become available. Turn the LDA
system off, wait for a little while,
and then turn the LDA system back
on.
“LDA Unavailable”
The LDA system is temporarily can-
celed due to a malfunction in a sensor
other than the camera sensor.
Turn the LDA system off and follow
the appropriate troubleshooting
procedures for the warning mes-
sage. Afterward, drive the vehicle
for a short time, and then turn the
LDA system back on.
“LDA Unavailable 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.

2584-5. Using the driving support systems
In vehicle-to-vehicle distance control mode, the vehicle automa tically
accelerates, decelerates and st ops to match the speed changes o f the
preceding vehicle even if the acc elerator pedal is not depressed. In
constant speed control mode, t he vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on f ree-
ways and highways.
● Vehicle-to-vehicle distance control mode ( P. 261)
● Constant speed c ontrol mode (P. 267)

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 paying careful attention to your sur-
roundings.
The dynamic radar cruise control with full-speed range provides driving
assistance to reduce the driver's burden. However, there are li mitations to
the assistance provided.
Set the speed appropriately depending on the speed limit, traff ic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condi tion
observed by the driver. Therefore, the driver must always remai n alert,
assess the danger of each situation and drive safely. Relying o n this system
or assuming the system ensures safety while driving can lead to an acci-
dent, resulting in death or serious injury.
■ Cautions 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 se rious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the following distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive driving, and it is not a system that
can assist the driver in low-visibility conditions. It is still necessary for
driver to pay close attention to the vehicle’s surroundings.
● Assisting 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 neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of danger in any given situation.
● Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range has limited capabil-
ity to prevent or avoid a collision with a vehicle traveling ah ead. Therefore,
if there is ever any danger, the driver must take immediate and direct con-
trol of the vehicle and act appropriately in order to ensure th e safety of all
involved.

2604-5. Using the driving support systems
WARNING
■To avoid inadvertent dynamic rad ar cruise control with full-speed
range activation
Switch the dynamic radar cruise control with full-speed range o ff using the
cruise control main switch when not in use.
■ Situations unsuitable for dynamic radar cruise control with ful l-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could ca use an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclists, etc.
● In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between s harp up
and down gradients
Vehicle speed may exceed the set speed when driving down a stee p hill.
● At entrances to freeways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When an approach warning buzzer is heard often
