■ If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in
the system.
● In the following situations, perform the actions specified in the table. When
the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact any authorized Toyot a retailer or
Toyota authorized repairer, or any reliable repairer.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached
matter. (P. 551)
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle 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 sys-
tem 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 after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature 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 camera.
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
materials on the radar and radar
cover, and if there is, remove it.

● 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 Toyot a 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 e xtremely
cold environment
• When the front camera cannot detect objects in front of the ve hicle, such
as when driving in the dark, snow, or fog, or when bright light s are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, th e radar may
judge the surrounding environment can not be properly recognize d. In
that case, “Pre-Collision System Unavailable See owner’s manual .” is
displayed.

PCS (Pre-Collision System)
: If equipped
The pre-collision system uses a radar sensor and front camera
to detect objects ( P. 370) 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 e va-
sive action and the potential brake pressure is increased to he lp
the driver avoid the collision. If the system determines that t he
possibility of a frontal collision with an object is extremely high,
the brakes are automatically applied to help avoid the collisio n
or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warnin g
timing can be changed. ( P. 375)

■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 co lli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brake pedal is depressed.
■Pre-collision braking
If the system determines that the possibility of a frontal coll ision is
extremely high, the brakes are automatically applied to help av oid
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 wi th a
pedestrian is high and that there is sufficient space for the v ehicle
to be steered into within its lane, and the driver has begun ev asive
maneuver or steering, emergency steering assist will assist the
steering movements to help enhance the vehicle stability and fo r
lane departure prevention.

■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
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.)

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 o perations
under any circumstances. This system will not prevent collision s or lessen
collision damage or injury in every situation. Do not overly re ly on this sys-
tem. Failure to do so may lead to an accident, resulting in dea th 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 accor ding 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. 380
• Conditions under which the system may not operate properly: P. 3 8 3
● Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard o bjects
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 braki ng 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 depr essed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent t he 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 pe dal is
depressed strongly or the steering wheel is turned and the syst em 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 operatio n timing of
the pre-collision braking function.

WARNING
■Emergency steering assist (for region A)
● As emergency steering assist operation will be canceled when the system
determines that lane departure prevention function has been com pleted.
● Emergency steering assist may not operate or may be cancel in the follow-
ing cases as the system may determine the driver is taking acti ons.
• If the accelerator pedal is being depressed strongly, the stee ring wheel
is being operated sharply, the brake pedal is being depressed o r the
turn signal lever is being operated. In this case, the system m ay 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 ope rating,
operation of the function may be canceled if the accelerator pe dal is
depressed strongly, the steering wheel is operated sharply or t he brake
pedal is being depressed and the system determines that the dri ver is
taking evasive action.
• When the emergency steering assist is operating, if the steeri ng 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-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 ser ious 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 dyna-
mometer or speedometer tester, or when using an on vehicle whee l bal-
ancer
● 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
