● In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disappear, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an extremely
cold environment
• When the front camera cannot detect objects in front of the vehicle, such
as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, the radar may
judge the surrounding environment can not be properly recognized. In
that case, “Pre-Collision System Unavailable” is displayed.

PCS (Pre-Collision System)
The system can detect the following:
● Ve hi cl e s
● Bicyclists
● Pedestrians
: If equipped
The pre-collision system uses a radar sensor and front camera
to detect objects ( P. 272) in front of the vehicle. When the sys-
tem determines that the possibility of a frontal collision with an
object is high, a warning operates to urge the driver to take eva-
sive action and the potential brake pressure is increased to help
the driver avoid the collision. If the system determines that the
possibility of a frontal collision with an object is extremely high,
the brakes are automatically applied to help avoid the collision
or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. ( P. 276)

■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.
■Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion 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.

WARNING
■Limitations of the pre-collision system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. 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 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 system may operate even if there is no pos-
sibility of a collision: P. 278
• Conditions under which the system may not operate properly: P. 2 8 0
● 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 may 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 braking func-
tion, the pre-collision braking func tion operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
● The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is bei ng turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function 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 the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

WARNING
■When to disable the pre-collision 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 engine running and the tires
are allowed to rotate freely
● When inspecting the vehicle using a drum tester such as a chassis
dynamometer or speedometer tester , 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 vehi-
cle 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
● When a compact spare tire or an emergency tire puncture repair kit is used
● If equipment (snow plow, etc.) that may obstruct the radar sensor or front
camera is temporarily installed to the vehicle

■Enabling/disabling the pre-collision system
The pre-collision system can be
enabled/disabled on
( P. 137) of the multi-informa-
tion display.
The system is automatically
enabled each time the engine
switch is turned to the “ON”
position (vehicles without smart
entry & start system) or IGNI-
TION ON mode (vehicles with
smart entry & start system).
If the system is disabled, the PCS warning light will turn on and a
message will be displayed on the multi-information display.
■Changing the pre-collision warning timing
The pre-collision warning timing
can be changed on
( P. 137) of the multi-informa-
tion display.
The warning timing setting is
retained when the engine switch
is turned to the “LOCK” position
(vehicles without smart entry &
start system) or off (vehicles
with smart entry & start system).
However, if the pre-collision sys-
tem is disabled and re-enabled,
the operation timing will return to
the default setting (middle).

■Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a detected object is high.
Each function is operational at the following speed
● Pre-collision warning
While the pre-collision warning function is operating, if the steering wheel is
operated heavily or suddenly, the pre-collision warning may be cancelled.
● Pre-collision brake assist
● Pre-collision braking
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)

■ Object detection function
■ Cancelation of the 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 turned sharply or abruptly.
■ Conditions under which the system may operate even if there is no pos-
sibility of a collision
● In some situations such as the following, the system may determine that
there is a possibility of a frontal collision and operate.
• When passing a detectable object, etc.
• When changing lanes while overtaking a detectable object, etc.
• When rapidly closing on a detectable object, etc.
• When approaching objects on the roadside, such as detectable objects,
guardrails, utility pol es, trees, or walls
The system detects objects based on
their size, profile, motion, etc. However,
an object may not be detected depending
on the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. ( P. 280)
The illustration shows an image of detect-
able objects.
• 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 wind-
ing road
• When there is a detectable object or
other object by the roadside at the
entrance of a curve
