Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on
(
98) of the multi-information dis-
play.
The warning timing setting is
retained when the engine switch is
turned OFF. However, if the pre-col-
lision system is disabled and
re-enabled, the operation timing will
return to the default setting (mid-
dle).
If the pre-collision warning tim-
ing is changed, emergency
steering assist timing will also
be changed accordingly. If late
is selected, emergency steering
assist would not operate in case
of an emergency.

Operational conditions for each pre-collision function
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a detected object is high.
The system may not operate in the following situations:
• If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
• If the shift lever is in R
• When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)
The operation speeds and operation cancellation for each function is listed
below.

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. (

Conditions under which the
system may operate even if
there is no possibility of a colli-
sion
●
In some situations such as the fol-
lowing, the system may determine
that there is a possibility of a fron-
tal collision and operate.
• When passing a detectable object,
etc.
• When changing lanes while over-
taking a detectable object, etc.
• When approaching a detectable
object in an adjacent lane or on
the roadside, such as when
changing the course of travel or
driving on a winding road
• When rapidly closing on a detect-
able object, etc.
• When approaching objects on the
roadside, such as detectable
objects, guardrails, utility poles,
trees, or walls
• When there is a detectable object
or other object by the roadside at
the entrance of a curve
• When there are patterns or paint
in front of your vehicle that may be
mistaken for a detectable object
• When the front of your vehicle is
hit by water, snow, dust, etc.
• When overtaking a detectable
object that is changing lanes or
making a right/left turn
• When passing a detectable object
in an oncoming lane that is
stopped to make a right/left turn

oncoming traffic
■
Situations in which the system
may not operate properly
●
In some situations such as the fol-
lowing, an object may not be
detected by the radar sensor and
front camera, preventing the sys-
tem from operating properly:
• When a detectable object is
approaching your vehicle
• When your vehicle or a detectable
object is wobbling
• If a detectable object makes an
abrupt maneuver (such as sudden
swerving, acceleration or deceler-
ation)
• When your vehicle approaches a
detectable object rapidly
• When a detectable object is not
directly in front of your vehicle
• When a detectable object is near
a wall, fence, guardrail, manhole
cover, vehicle, steel plate on the
road, etc.
• When a detectable object is under
a structure
244
4-5. Using the driving support systems
• When part of a detectable object
is hidden by an object, such as
large baggage, an umbrella, or
guardrail

which can reflect the radio waves
of the radar in the vicinity (tunnels,
truss bridges, gravel roads, snow
covered road that have tracks,
etc.)
• When there is an effect on the
radio waves to the radar that is
installed on another vehicle
• When multiple detectable objects
are close together

front of a vehicle ahead
• If a vehicle ahead is a motorcycle
• If a vehicle ahead is narrow, such
as a personal mobility vehicle
• If a preceding vehicle has a small
rear end, such as an unloaded
truck
• If a preceding vehicle has a low
rear end, such as a low bed trailer
• If a vehicle ahead has extremely
high ground clearance
• If a vehicle ahead is carrying a
load which protrudes past its rear

are difficult to see, such as when
they are faint, diverging/merging,
or a shadow is cast upon them

tern on the road surface, such as
due to road repairs

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, sufficient 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, extremely hot, or
wet
• If the vehicle is not properly main-
tained (brakes or tires are exces-
sively worn, improper 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

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.257) 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.

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 pressure 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 grille 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.
