■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
“BRAKE!”
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
■Emergency steering assist (for
region A)
If the system determines that the
possibility of a collision with a
pedestrian is high and that there is
sufficient space for the vehicle to be
steered into within its lane, and the
driver has begun evasive maneuver
or steering, emergency steering
assist will assist the steering move-
ments to help enhance the vehicle
stability and for lane departure pre-
vention. During operation, the indi-
cator will illuminate in green.
■Intersection right/left turn
assistance (for region A)
If the system determines that there
is a high possibility of a collision in
the following situations, it will assist
with Pre-collision warning and, if
necessary Pre-collision braking.
Depending on the configuration of
the intersection, it may not be pos-
sible to support.

■Enabling/disabling the pre-col-
lision system
The pre-collision system can be
enabled/disabled on ( P.457)
of the multi-information display.
The system is automatically enabled
each time the engine switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a

■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on ( P.457) of
the multi-information display.
The warning timing setting is retained
when the engine switch is turned off.
However, if the pre-collision system is
disabled and re-enabled, the operation
timing will return to the default setting
(middle).
For region A: If the pre-collision warn-
ing timing 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.

*: If equipped
While driving on a road with clear
white (yellow) lane lines, the LTA
system warns the driver if the vehi-
cle 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 control 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 camera. Additionally,
it detects preceding vehicles using
the front camera and radar.

WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically 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 surrounding conditions and operating the steering wheel to cor-
rect 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 driv-
ing operations and pay careful 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. Fail-ure to do so may lead to an accident,
resulting in death or serious injury.
●Vehicle is driven on a road surface
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 con-
struction work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc., are
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.
●When your vehicle is towing a trailer or during emergency towing.
■Preventing LTA system malfunc-tions 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 any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not install or place anything on the hood or grille. Also, do not
install a grille guard (bull bars, kan- garoo bar, etc.).
●If your windshield needs repairs, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■Conditions in which functions
may not operate properly
In the following situations, the func- tions may not operate properly 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.
●When the follow-up cruising dis-play is displayed ( P.234) and the
preceding vehicle changes lanes. (Your vehicle may follow the pre-ceding vehicle and also change
lanes.)
