● 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 your Toyota dealer.
• 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 cannot be properly recognized. In
that case, “Pre-Collision System Unavailable See Owner's Manual” is dis-
played.

PCS (Pre-Collision System)
The pre-collision system uses a radar sensor and front camera
to detect objects (P. 228) 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. 233)
Detectable objects
The system can detect the following (The detectable objects differs
depending on the function.):
● Vehicles
● Bicyclists
● Pedestrians
System functions
■ 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.
■ Emergency steering assist
If the system determines that the possibility of a frontal collision 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
prevention.
During operation, the indicator
will illuminate in green.

■ Intersection right/left turn assistance
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
possible to support.
● When you turn right/left at an
intersection and cross the
path of an oncoming vehicle

● When you turn right/left,
pedestrian is detected in the
forward direction and esti-
mated to enter your vehicle’s
path
(bicyclists are not
detected.)
■ Suspension control (if equipped)
When the system determines that the possibility of a frontal colli-
sion is high, the Adaptive Variable Suspension System (P. 329)
will control the damping force of the shock absorbers to help main-
tain an appropriate vehicle posture.
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. 237
• Conditions under which the system may not operate properly: P. 239
● 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.

WARNING
■ 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 function 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 being 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.
4
● 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.
■ 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 follow-
ing cases as the system 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 system may deter-
mine that the driver is taking evasive action and the emergency steering
assist may not operate.
• In some situations, while the emergency steering assist is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly, the steering wheel is operated sharply or the brake
pedal is being depressed and the system determines that the driver is
taking evasive action.
• When the emergency steering assist is operating, if the steering wheel
is held firmly or is operated in the opposite direction to that which the
system is generating torque, the function may be canceled.
