*: If equipped
The system can detect the follow -
ing:
 Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message wil l be displayed
on the multi-information display to
urge the driver to take evasive
action.
■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 fr ontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam -
era to detect objects ( →P.355)
in front of the vehicle. When
the system determines that the
possibility of a fr ontal collision
with an object is high, a warn -
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to help the driver
avoid the collision. If the sys -
tem determines that the possi -
bility of a fronta l collision with
an object is extremely high,
the brakes are automatically
applied to help avoid the colli -
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn -
ing timing can be changed.

WARNING
■Limitations of the pre-collision
system
●The driver is solely responsible for safe driving. Always drive safely,
taking care to observe your sur -
roundings. Do not use the pre- collision system
instead of normal braking opera -
tions under any circumstances.
This system will not prevent colli - sions or lessen collision damage or
injury in every situation. Do not
overly rely on thi s system. Failure to do so may lead to an accident,
resulting in death or serious injury.
●Although this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effec - tiveness may change according to
various conditions, therefore the
system may not alw ays be able to achieve the same level of perfor -
mance.
Read the following conditions care - fully. Do not over ly rely on this sys-
tem and always drive carefully.
• Conditions under which the system may operate even if there is no pos -
sibility of a collision: →P.359
• Conditions under which the system may not operate properly: →P.360
●Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects imitating detectable objects,
etc.), the system m ay not operate
properly, possibly 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 brak -
ing function, the p re-collision brak-
ing function operation will be canceled after approximately 2 sec -
onds. Depress the brake pedal as
necessary.
●The pre-collision braking function
may not operate if certain opera - tions 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 tak -
ing evasive action and possibly pre - vent the pre-col lision braking
function from operating.
●In some situations, while the pre-
collision braking function is operat -
ing, operation of the function may be canceled if the accelerator pedal
is depressed strongly or the steer -
ing wheel is tur ned and the system determines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may deter -
mine that the driv er is taking eva- sive action and possibly delay the
operation timing of the pre-collision
braking function.
■When to disable the pre-colli -
sion system
In the following situations, disable the
system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing
another vehicle
●When transporting the vehicle via truck, boat, train or similar means of
transportation
●When the vehicle is raised on a lift
with the hybrid system on and the
tires are allowed to rotate freely

■Enabling/disabling the pre-col -
lision system
The pre-collisio n system can be
enabled/disabled on the screen
( →P.186) of the multi-information
display.
The system is automa tically enabled
each time the power switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a
message will be di splayed on the
multi-information display.
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on the screen
( →P.186) of the multi-information
display.
The warning timing setting is retained
when the power switch is turned to
OFF. However, if the pre-collision sys-
tem is disabled and re-enabled, the
operation timing will return to the
default setting (middle).
WARNING
●When inspecting the vehicle using
a drum tester su ch as a chassis
dynamometer or speedometer tes- ter, or when using an on vehicle
wheel balancer
●When a strong impact is applied to
the front bumper or front grille, due
to an accident or other reasons
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than
specified are installed
●When tire chains are installed

LTA (Lane Tracing
Assist)*
When driving on highways and
freeways with white (yellow)
lane lines, this function alerts
the driver when the vehicle
might depart from its lane or
course* and provides assis -
tance by operating the steering
wheel to keep the vehicle in its
lane or course*. Furthermore,
the system provides steering
assistance when dynamic
radar cruise control with full-
speed range is operating to
keep the vehic le in its lane.
The LTA system recognizes
white (yellow) l ane lines or a
course* using the front cam -
era. Additionally, it detects pre -
ceding vehicles using the front
camera and radar.

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 stee ring wheel to cor-
rect the path of t he 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.
●When not u sing the LTA system, use the LTA switch to turn the sys -
tem off.
■Situations unsuitable for LTA
system
In the following situations, use the LTA switch to tu rn the system off.
Failure to do so may lead to an acci -
dent, 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.
