■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).
When the brake pedal is stepped on, the system judges if evasion actions are
being done by the driver and the start timing for pre-crash braking may be
delayed.
During the following, the driver operations takes precedence and the system
may not operate:
● The accelerator pedal is depressed strongly
● The steering wheel is turned sharply or abruptly
In case of the following, the system will not operate:
● 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
● When the shift position is in R
■ 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
( P. 308, 317)
• 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. 262), 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 orserious 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. 230). 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-crashbraking 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 depressedstrongly or the steering wheel is turned and the system determines that the driver is taking evasive action.
● While driving, the system may recognize front obstacles, such as the crossing gate of a railway crossing, as a collision objects and operate thepre-crash brake.In the event that the vehicle gets caught within the railroad crossing, move the vehicle with the following actions and depending on the situation main- tain safety.
• Depress the accelerator pedal after the vehicle has stopped
• Strongly depress the accelerator pedal when decelerating ( P. 230)
• Turn the Pre-crash safety system OFF ( P. 229)
● 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 ofLOOK-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 frontof 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 theyonly 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 operationsbeing 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
