that the vehicle might depart
from its lane, a warning is dis-
played on the multi-information
display and the warning buzzer
sounds to alert the driver.
When the warning buzzer
sounds, check the surrounding
road situation and carefully
operate the steering wheel to

◆Steering control function
When the system determines
that the vehicle might depart
from its lane, the system pro-
vides assistance as necessary
by operating the steering wheel
in small amounts for a short
period of time to keep the vehi-
cle in its lane.
If the system detects that the
steering wheel has not been
operated for a fixed amount of
time or the steering wheel is not
being firmly gripped, a warning
is displayed on the multi-infor-
mation display and the function
is temporarily canceled.

appears as if it may depart from
its lane multiple times, the

WARNING
■Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
■To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.

WARNING
■Situations unsuitable for LDA system
Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, resulting in
death or serious injury.
●A spare tire, tire chains, etc. are equipped.
●When the tires have been excessively worn, or when the tire inflation pres-
sure is low.
●Tires which differ by structure, manufacturer, brand or tread pattern are
used.
●Objects or patterns that could be mistaken for white (yellow) lines are
present on the side of the road (guardrails, curbs, reflective poles, etc.).
●Vehicle is driven on a snow-covered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Asphalt repair marks, white (yellow) line marks, etc. are present due to
road repair.
●Vehicle is driven in a temporary lane or restricted lane due to construction
work.
●Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
●Vehicle is driven in traffic lanes other than on highways and freeways.
●Vehicle is driven in a construction zone.
■Preventing LDA system malfunctions and operations performed by
mistake
●Do not modify the headlights or place stickers, etc. on the surface of the
lights.
●Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
●Do not install or place anything on the hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar, etc.).

■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. 259)
■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 noise, 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 your hands on
the steering wheel when using this system, regardless of warnings.
Depending on the vehicle and road conditions, the warning may not operate.
■Vehicle sway warning function
Depending on the vehicle and road conditions, the warning may not operate.
■White (yellow) lines are only on one side of road
The LDA system will not operate for the side on which white (yellow) 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.

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 limitations to
the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:
P. 274
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 275
●Set the speed appropriately depending on the speed limit, traffic 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 condition
observed by the driver. Therefore, the driver must always remain alert,
assess the danger of each situation and drive safely. Relying on this sys-
tem or assuming the system ensures safety while driving can lead to an
accident, resulting in death or serious injury.
●Switch the dynamic radar cruise control with full-speed range off using the
cruise control main switch when not in use.
■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 serious 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.
