WARNING
The front sensor uses lasers to detect vehicles ahead of your vehicle. The
front sensor is classified as class 1M laser product according to the IEC
60825-1 standard. Under normal usage conditions, these lasers are not harm-
ful to the naked eye. However, it is necessary to observe the following precau-
tions.
Failure to do so may result in the loss of eyesight or severe visual impairment.
● To avoid hazardous laser radiation exposure, never attempt to disassem-
ble the front sensor (e.g. remove the lenses). When disassembled, the
front sensor is classified as a class 3B laser product according to the IEC
60825-1 standard. Class 3B lasers are hazardous and pose a risk of eye
injury under direct exposure.
● Do not attempt to look into the front sensor with a magnifying glass, micro-
scope or other optical instrument within a distance of less than 100 mm
(3.9 in.).

PCS (Pre-Crash Safety system)∗
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision with a vehicle is high, a
buzzer will sound and the PCS
activation indicator will flash to
urge the driver to take evasive
action.
◆Pre-crash brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system applies greater braking force
in relation to how strongly the brake pedal is depressed.
◆Pre-crash braking
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically applied to help avoid the collision or
reduce the collision speed.
∗: If equipped
The pre-crash safety system uses the front sensor to detect
vehicles in front of your vehicle. When the system determines
that the possibility of a frontal collision with a vehicle is high,
pre-crash warning urges the driver to take evasive action and
the potential brake pressure will be increased to help the driver
avoid the collision.
If the system determines that the possibility of a frontal collision
with a vehicle is extremely high, the brakes are automatically
applied to help avoid the collision or help reduce the impact to
the vehicle occupants and the vehicle in the collision.
The pre-crash warning timing can be changed or the system can be
enabled/disabled, as necessary, by operating the switch. ( →P. 216)

■Operational conditions
The pre-crash safety system is enabled and determines that the possibility of
a frontal collision with a vehicle (e xcept motorcycles and bicycles) is high.
● Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 86 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 15 km/h (10 mph).
● Pre-crash brake assist:
• Vehicle speed is approximately 30 to 80 km/h (19 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 30 km/h (19 mph).
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 10 km/h (7 mph).
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 VSC is disabled (only the pre-crash warning function will be operational)
● If the PCS warning light is flashing or illuminated
■ Cancelation of the pre-crash braking
● If either of the following situations occur while the pre-crash braking function
is operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
● If the vehicle is stopped by the operation of the pre-crash braking function,
the operation of the pre-crash braking function will be canceled after the
vehicle has been stopped for approximately 2 seconds.

■ If the PCS warning light flashes
The pre-crash safety system may be temporarily unavailable or there may be
a malfunction in the system.
● In the following situations, the warning light will be cleared and the system
will become operational when normal operating conditions return:
• When the area around the front sensor is hot, such as after the vehicle
has been parked in the sun
• When the windshield is fogged up or covered with condensation or ice
• If the area in front of the front sens or is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash, the system may be malfunction-
ing. Have the vehicle inspected by any authorized Toyota dealer or repairer,
or another duly qualified and equi pped professional immediately.
■ If the TRC and VSC are disabled
● If the TRC and VSC are disabled (→P. 239), pre-crash brake assist and pre-
crash braking are also disabled. However, the pre-crash warning function
will still operate.
● The PCS warning light illuminates.

WARNING
■ Limitations of the pre-crash safety system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-crash safety sy stem instead of normal braking opera-
tions under any circumstances. This system will not prevent collisions or
lessen damage or injuries 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.
Although this system is designed to help avoid and reduce the impact of a
collision, its effectiveness may change according to various conditions
( →P. 217). As a result, the system may not always provide the same level
of performance.
● The pre-crash 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 bei ng turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-crash
braking function from operating.
● In some situations, while the pre-crash braking function is operating, oper-
ation of the function may be canceled if the accelerator pedal is depressed
strongly or the steering wheel is turned and the system determines that
the driver is taking evasive action.
● A large amount of braking force is applied while the pre-crash braking
function is operating. Additionally, as the vehicle may creep after the pre-
crash braking function has operated, the driver should depress the brake
pedal as necessary.

WARNING
■ Cautions regarding the assist functions of the system
By means of warnings and brake control, the pre-crash safety system is
intended to assist the driver in avoiding collisions through the process of
LOOK-JUDGE-ACT. There are limits to the degree of assistance the system
can provide, so keep in mind the following important points.
● Assisting the driver in watching the road
The pre-crash safety system is only able to detect vehicles directly in front
of your vehicle, and only within a limi ted range. It does not allow for care-
less or inattentive driving, and is not a system that can assist the driver in
low-visibility conditions. It is still necessary for the driver to pay close atten-
tion to the vehicle’s surroundings.
● Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-crash safety system is that from vehicles it has
detected directly in front of the vehicle. Therefore, it is absolutely neces-
sary for the driver to remain vigila nt and to determine whether or not there
is a possibility of collision in any given situation.
● Assisting the driver in taking action
The pre-crash brake assist and pre- crash braking functions are designed
to help avoid a collision or reduce the severity of a collision, as such they
only operate when the system has determined that the possibility of a col-
lision is high. This system is not capable of automatically avoiding a colli-
sion or bringing the vehicle to a stop safely, without appropriate operations
being performed by the driver. For this reason, when encountering a dan-
gerous situation the driver must take direct and immediate action in order
to ensure the safety of all involved.
NOTICE
■ To avoid malfunction of the system
In the following situations, disable the pre-crash safety system. The system
may operate even if there is no possibility of a collision.
● When inspecting the vehicle using a drum tester such as a chassis dyna-
mometer or speedometer tester, or when using an on vehicle wheel bal-
ancer
● When transporting the vehicle via boat, truck, or similar means of transpor-
tation
● When the front part of the vehicle is raised or lowered, such as if tires of a
different size than specified are used or if the suspension components are
modified
● When the vehicle is being towed

■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
● The turn signal lever is operated.
● The vehicle speed deviates from the operating range of the LDA system
functions.
● When the lane lines cannot be recognized while driving.
● When the lane departure warning sounds.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
■ The lane departure warning
Depending on the audio system sound level or air conditioning fan noise
while the audio system or air conditioning sy stem is in use, it may be difficult
to hear the warning sound.
■ After the vehicle has been parked in the sun
The LDA system may not be immediatel y available. When the temperature in
the cabin decreases and the temperature around the front sensor ( →P. 212)
becomes suitable for its operation, the functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane mark-
ers could not be recognized.
■ Conditions in which the function may not operate correctly
In the following situations, the front sensor may be unable to recognize lane
markers causing the lane departure warning function to operate incorrectly.
However, this does not indicate a malfunction.
● When driving through an area, such as a tollbooth, a crossing or before a
ticket checkpoint
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a heavy load
or improper tire inflation pressure
● When the following distance between your vehicle and the vehicle ahead is
extremely short
● When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
● When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
