PCS (Pre-Collision System)
: If equipped
The pre-collision system uses a radar sensor and camera sen- 
sor to detect vehicles and pedestrians* in front of your vehicle. 
When the system determines that the possibility of a frontal col- 
lision with a vehicle or pedestrian 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 possibility 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 the 
impact of the collision. 
The pre-collision system can be disabled/enabled and the warning 
timing can be changed. ( P. 302)
*: Depending on the region in which the vehicle was sold, the pedestrian 
detection function may not be available. Contact any authorized Toyota
retailer or Toyota authorized repairer,  or any reliable repairer for details.

◆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 relation to 
how strongly the brake 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 determines 
that the possibility of a frontal collision is extremely high, the brakes 
are automatically applied to help 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 operations 
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys- 
tem. Failure to do so may lead to an accident, resulting in death 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 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. 308 
• Conditions under which the system may not operate properly:  P.  3 11 
● Do not attempt to test the operation of the pre-collision system yourself, as 
the system may not operate properly, possibly leading to an accident. 
■ Pre-collision braking 
● 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 bei ng 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 system 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.

● 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 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 
● When the tires are very worn 
● When tires of a size other than specified are installed
