●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 mes-
sage will disappear and the system will become operational.
SituationActions
When the area around a camera is cov-
ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached mat-
ter. (P.431)
When the temperature around the front
camera is outside of the operational
range, such as when the vehicle is in the
sun or in an extremely cold environment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the
sunlight reflected from the surface of the
sunshade may cause the temperature of
the front camera to become excessively
high.
If the front camera is cold, such as after
the vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.
The area in front of the front camera is
obstructed, such as when the hood is
open or a sticker is attached to the part of
the windshield in front of the front cam-
era.
Close the hood, remove the sticker, etc.
to clear the obstruction.
When “Pre-Collision System Radar In
Self Calibration Unavailable See
Owner’s Manual” is displayed.Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

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 operational 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-Colli-
sion System Unavailable See Owner’s Manual” is displayed.

*: If equipped
The system can detect the follow-
ing (The detectable objects differs
depending on the function.):
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 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 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
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
PCS (Pre-Collision Sys-
tem)
*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects (P.343)
in front of the vehicle. When
the system determines that the
possibility of a frontal 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 frontal 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.

into within its lane, and the driver
has begun evasive maneuver or
steering, emergency steering assist
will assist the steering movements
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 pos-
sible to support.
 When you turn right/left at an
intersection and cross the path of
an oncoming vehicle
 When you turn right/left, pedes-
trian is detected in the forward
direction and estimated to enter
your vehicle’s path (bicyclists are
not detected.)
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 this system. Failure to do so may lead to an accident,
resulting in death or serious injury.

WARNING
●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 always be able to achieve the same level of perfor-mance.
Read the following conditions care- fully. Do not overly 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.349
• Conditions under which the system may not operate properly: P.351
●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 brak-ing function, the pre-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-collision 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 turned 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 driver is taking eva-
sive action and possibly delay the operation timing of the pre-collision braking function.
■Emergency steering assist
●As emergency steering assist oper-
ation will be canceled when the sys- tem determines that lane departure prevention function has been com-
pleted.
●Emergency steering assist may not
operate or may be cancel in the fol- lowing 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 determine that the driver is tak-
ing evasive action and the emer- gency steering assist may not operate.
• In some situations, while the emer- gency 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.

3465-5. Using the driving support systems
■Enabling/disabling the pre-col-
lision system
The pre-collision system can be
enabled/disabled on the screen
( P.206, 217) of the multi-informa-
tion display.
The system is automatically 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 displayed on the
multi-information display.
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on the screen
( P.206, 217) of the multi-informa-
tion display.
WARNING
• 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.
■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
●When inspecting the vehicle using a drum tester such 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
●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
