PCS (Pre-Collision System)
: If equipped
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedest rians in front of your vehicle.
When the system determines that t he possibility of a frontal col-
lision with a vehicle or pedest rian is high, a warning 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
system determines that the possi bility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce th e
impact of the collision.
The pre-collision system can b e disabled/enabled and the warnin g
timing can be changed. ( P. 2 5 3 )

◆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 brak e pedal is depressed.
◆Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determ ines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to hel p avoid the collision or reduce the
collision speed.

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. 255
• Conditions under which the system may not operate properly: P. 258
● Do not attempt to test the operation of the pre-collision syste m yourself, as
the system may not operate properly, possibly leading to an acc ident.
■ 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 o perations 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 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 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 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 engine running an d 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 cam-
era sensor is temporarily installed to the vehicle

■Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
● Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 1 80 km/h).
(For detecting a pedestrian, vehicle speed is between approxima tely 7 and
50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 7 mph (10 km/h) or more.
● Pre-collision brake assist:
• Vehicle speed is between approximately 20 and 110 mph (30 and
180 km/h). (For detecting a pedestrian, vehicle speed is between approx-
imately 20 and 50 mph [30 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 20 mph (30 km/h) or more.
● Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 1 80 km/h).
(For detecting a pedestrian, vehicle speed is between approxima tely 7 and
50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 7 mph (10 km/h) or more.
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
● If VSC is disabled (only the pre-collision warning function wil l be opera-
tional)

■If the PCS warning light flashes or illuminates and a warning m essage is
displayed on the multi-information display
The pre-collision system may be temporarily unavailable or ther e may be a
malfunction in the system.
● In the following situations, the warning light will turn off, t he message will
disappear and the system will become operational when normal op erating
conditions return:
• When the radar sensor or camera sensor or the area around eith er sen-
sor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around eith er sen-
sor is cold, such as in an extremely cold environment
• When a front sensor is dirty or covered with snow, etc.
• When the part of the windshield in front of the camera sensor is fogged
up or covered with condensation or ice
(Defogging the windshield: P. 393)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
● If the PCS warning light continues to flash or remains illumina ted or the
warning message does not disappear even though the vehicle has returned
to normal, the system may be malfunctioning. Have the vehicle inspected by
your Toyota dealer immediately.
■ If VSC is disabled
●If VSC is disabled ( P. 374), 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.

The LDA system recognizes visi-
ble white (yellow) lines with the
camera sensor on the upper por-
tion of the front windshield.
◆Lane departure alert function
When the system determines
that the vehicle might depart
from its lane, a warning is dis-
played on the multi-information
display and the warning buzzer
sounds to alert the driver.
When the warning buzzer
sounds, check the surrounding
road situation and carefully
operate the steering wheel to
move the vehicle back to the
center of the lane.
