2264-5. Using the driving support systems
■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 t he 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 your Toyota dealer.
SituationAction
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter. ( P. 344)
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 displayedCheck whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

2284-5. Using the driving support systems
The system can detect the following (The detectable objects dif fers
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 colli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brake pedal is depressed.
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 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 impa ct of the collision.
The pre-collision system can b e disabled/enabled and the warnin g
timing can be changed. ( P. 2 3 3 )

■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 th e 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 s teered
into within its lane, and the dr iver has begun evasive maneuver or
steering, emergency steering assist will assist the steering move-
ments to help enhance the vehicle stability and for lane depart ure
prevention.
During operation, the indicator
will illuminate in green.
■Intersection right/left turn assistance
If the system determines that t here 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

2304-5. Using the driving support systems
●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 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 h elp 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 syste m 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.

WARNING
■Pre-collision braking
● When the pre-collision braking function is operating, a large a mount 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 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 operation timing of
the pre-collision braking function.
■ Emergency steering assist
● As emergency steering assist operation will be canceled when th e 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 acti ons.
• If the accelerator pedal is being depressed strongly, the steering 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 steeri ng 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 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.

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 chass is 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 gr ille, 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 sens or 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. 1 0 1 )
of the multi-information display.
The system is automatically enabled each time the engine switch is
turned to IGNITION ON mode.
If the system is disabled, the
PCS warning light will turn on
and a message will be dis-
played on the multi-information
display.
■Changing the pre-colli sion warning timing
The pre-collision warning timing can be changed on ( P. 1 0 1 )
of the multi-information display.
The warning timing setting is retained when the engine switch is turned
off. However, if the pre-collision system is disabled and re-en abled, the
operation timing will return to the default setting (middle).
If the pre-collision warning timing is changed, e mergency steering
assist timing will also b e changed accordingly.
If late is selected, emergency st eering assist would not operate in
case of an emergency.

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. 239)
The illustration shows an image of detect-
able objects.

2424-5. Using the driving support systems
●In some situations such as the following, sufficient braking force or steering
force may not be obtained, preventing the system from performin g properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
• When the road surface has deep wheel tracks
• When driving on a hill road
• When driving on a road that has inclines to the left or right
■ If VSC is disabled
●If VSC is disabled ( P. 330), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC Turned Off Pre-Coll ision Brake
System Unavailable” will be displayed on the multi-information display.
