●Intersection right/left turn assistance (pre-collision warning)
When the turn signal lights are not flashing, support for turning left or right at
an intersection which targets on coming vehicles does not work.

■Object detection function
The system detects objects based
on their size, profile, motion, etc.
However, an object may not be
detected depending on the sur- rounding brightness and the motion,
posture, and angle of the detected
object, preventing the system from
operating properly. (

driven for a certain amount of time
• While making a left/right turn and
for a few seconds after making a
left/right turn
• While driving on a curve and for a
few seconds after driving on a
curve
• If your vehicle is skidding
• If the front of the vehicle is raised
or lowered
• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera
is misaligned
• When driving in a traffic lane sep-
arated by more t han one lane
where oncoming vehicles are driv-
ing while making a right/left turn
• When largely out of place with the opposite facing targeted oncom-
ing vehicle during a right/left turn
• While making a right/left turn, when a pedestrian approaches
from behind or side of your vehicle
●In addition to the above, in some
situations, such as the following,
the emergency steering assist
may not operate.
• When the white (yellow) lane lines are difficult to see, such as when
they are faint, diverging/merging,
or a shadow is cast upon them
• When the lane is wider or nar-
rower than normal
• When there is a light and dark pat- tern on the road surface, such as
due to road repairs
• When the target is too close
• When there is insufficient safe or unobstructed space for the vehicle
to be steered into
• If oncoming vehicle is present
• If VSC function is operating
●In some situations such as the fol-
lowing, sufficien t braking force or
steering force may not be
obtained, preventing the system
from performing properly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, ext remely hot, or
wet
• If the vehicle is not properly main- tained (brakes or tires are exces-
sively worn, imprope r tire inflation
pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery
surface
• When the road surface has deep wheel tracks
• When driving on a hill road
• When driving on a road that has inclines to the left or right
■If VSC is disabled
●If VSC is disabled ( P.327), the

pre-collision braking functions are
also disabled.
●The PCS warning lig

LTA (Lane Tracing
Assist)
While driving on a road with
clear white (yellow) lane
lines, the LTA system warns
the driver if the vehicle may
deviate from the current
lane or course
*, and also
can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*. Also, while the
dynamic radar cruise con-
trol with full-speed range
( P.271) is operating, this
system will operate the
steering wheel to maintain
the vehicle’s lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects
preceding vehicles using
the front camera and radar.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb

WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle 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 atten-
tion to the surrounding condi-
tions 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 care-
ful attention may lead to an
accident, resulting in death or
serious injury.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face which is slippery due to
rainy weather, fallen snow,
freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.
●White (yellow) lines are difficult
to see due to rain, snow, fog,
dust, etc.
●Vehicle is driven in a temporary
lane or restricted lane due to
construction work.
●Vehicle is driven in a construc-
tion zone.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been
excessively worn, or when the
tire inflation p ressure is low.
●When your vehicle is towing a
trailer or during emergency tow-
ing.
■Preventing LTA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc. on the sur-
face 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 gr ille guard (bull
bars, kangaroo bar, etc.).
●If your windshield needs
repairs, contact your Toyota
dealer.
■Conditions in which functions
may not operate properly
In the following situations, the
functions may not operate prop-
erly and the vehicle may depart
from its lane. Drive safely by
always paying careful attention to
your surroundings and operate
the steering wheel to correct the
path of the vehicle without relying
solely on the functions.

■Lane departure alert func-
tion
When the system determines
that the vehicle might depart
from its lane or course
*, a warn-
ing is displayed on the
multi-information display, and a
warning buzzer will sound to
alert the driver.
When the warning buzzer sounds,
check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane.
When the system de termines that
the vehicle might depart from its
lane and that the possibility of a col-
lision with an over taking vehicle in
the adjacent lane is high, the lane
departure alert will operate even if
the turn signals are operating.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb
■Steering assist function
When the system determines
that the vehicle might depart
from its lane or course
*, the sys-
tem provides assistance as nec-
essary by operating the steering
wheel in small amounts for a
short period of time to keep the
vehicle in its lane.
When the system determines that
the vehicle might depart from its
lane and that the possibility of a col-
lision with an overta king vehicle in
the adjacent lane is high, the steer-
ing assist function will operate even
if the turn signals are operating.

■Vehicle sway warning func-
tion
When the vehicle is swaying
within a lane, the warning
buzzer will sound and a mes-
sage will be displayed on the
multi-information display to alert
the driver.■Lane centering function
This function is linked with
dynamic radar cruise control
with full-speed range and pro-
vides the required assistance by
operating the steering wheel to
keep the vehicle in its current
lane.
When dynamic radar cruise control
with full-speed range is not operat-
ing, the lane centering function
does not operate.
In situations where the white (yel-
low) lane lines are d ifficult to see or
are not visible, such as when in a
traffic jam, this function will operate
to help follow a preceding vehicle
by monitoring the position of the
preceding vehicle.
