2304-5. Using the driving support systems
WARNING
●Although this system is
designed to help avoid a colli-
sion or help reduce the impact
of the collision, its effectiveness
may change according to vari-
ous conditions, therefore the
system may not always be able
to achieve the same level of
performance.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.
• Conditions under which the sys- tem may operate even if there is
no possibility of a collision:
P. 2 3 5
• Conditions under which the sys- tem may not operate properly:
P. 2 3 6
●Do not attempt to test the oper-
ation of the pre-collision system
yourself.
Depending on the objects used
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system
may not operate properly, possi-
bly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision
braking function, the pre-colli-
sion braking function operation
will be canceled after approxi-
mately 2 second s. Depress the
brake pedal as necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●In some situations, while the
pre-collision brak ing function is
operating, operation of the func-
tion may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is
turned and the system deter-
mines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may
determine that t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision braking function.
■Emergency steering assist
●As emergency steering assist
operation will be canceled when
the system determines that lane
departure prevention function
has been completed.
●Emergency steering assist may
not operate or may be cancel in
the following cases as the sys-
tem may determine the driver is
taking actions.
• If the accelerator pedal is being depressed strongly, the steering
wheel is being operated sharply,
the brake pedal is being
depressed or the turn signal
lever is being operated. In this
case, the syst em may deter-
mine that the driver is taking
evasive action and the emer-
gency steering assist may not
operate.

While the pre-collision warning function is operating, if the steering wheel is
operated heavily or suddenly, the pre-collis ion warning may be cancelled.
●Pre-collision brake assist
●Pre-collision braking
If either of the following occur while the pre-collision braking function is oper-
ating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is tur ned sharply or abruptly.
●Emergency steering assist
When the turn signal lights are flashing, emergency steering as sist will not
operate in case of an emergency.

If any of the following occur while the emergency steering assi st function is
operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is tur ned sharply or abruptly.
• The brake pedal is depressed.
●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.
●Intersection right/left turn assistance (pre-collision braking)
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. (

pre-collision brake assist and

also disabled.
●The PCS warning light will turn on
and “VSC Turned OFF Pre-Colli-

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.249) 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.

Driving
■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.
Vehicle with BSM: When the sys-
tem determines that the vehicle
might depart from its lane and that
the possibility of a collision with an
overtaking vehicle in the adjacent
lane is high, the lane departure
alert will operate e ven 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.
Vehicle with BSM: When the sys-
tem determines that the vehicle
might depart from its lane and that
the possibility of a collision with an
overtaking vehicle in the adjacent
lane is high, the steering assist
function will operate even if the turn
signals are operating.
