• : If equipped
  The pre-collision system uses sensors to detect objects (Toyota car service centre | Book Car Service Appointment Online (toyotabharat.com)) in the path of the vehicle. When the system determines that the possibility of a frontal collision with a detectable object 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 collision is extremely high, the brakes are automatically 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. (Click here)
  Available functions differ depending on the country/area. For details, check the detectable objects and functions list.

WARNING
For safe use

• Driving safely is solely the responsibility of the driver. Pay careful attention to the surrounding conditions in order to ensure safe driving.
  Never use the pre-collision system in place of normal braking operations. This system cannot help avoid or reduce the impact of a collision in every situation. Over-reliance on this system to drive the vehicle safely may lead to an accident resulting in death or serious injury.

• Although the pre-collision system is designed to help avoid or help reduce the impact of a collision, its effectiveness may change according to various conditions. Therefore, it may not always be able to achieve the same level of performance.
  Read the following items carefully. Do not overly rely on this system and always drive carefully.

System functions

∎ Pre-collision warning
When the system determines that the possibility of a collision is high, a buzzer will sound and an icon and warning message will be displayed on the multi-information display to urge the driver to take evasive action.
If the detectable object is a vehicle, moderate braking will be performed with the warning.

If the system determines that the accelerator pedal is strongly depressed, the following icon and message will be displayed on the multi-information display.

∎ Pre-collision brake assist
If the system determines that the possibility of a collision is high and the brake operation by the driver is insufficient, the braking power will be increased.
∎ Pre-collision brake control
If the system determines that the possibility of a collision is extremely high, the brakes are automatically applied to help avoid the collision or reduce the impact of the collision.
∎ Emergency steering assist
If the system determines that the following conditions are met, assistance will be provided to help enhance vehicle stability and prevent lane departure. During assistance, in addition to the pre-collision warning, the following icon will be displayed on the multi-information display.

• The possibility of a collision is high
• There is sufficient space within the lane to perform evasive steering maneuvers
• The driver is operating the steering wheel
  During assistance, the pre-collision warning will operate and a message will be displayed to warn the driver.

∎ Intersection collision avoidance support (left/right turn)
In situations such as the following, if the system determines that the possibility of a collision is high, the pre-collision warning and pre- collision braking will operate. Depending on the intersection, assistance may not operate correctly.

• When turning left/right at an intersection and crossing the path of an oncoming vehicle
• When turning left/right and a pedestrian or bicycle is detected

∎ Intersection collision avoidance support (crossing vehicles)
At an intersection, etc., if the system determines that the possibility of a collision with an approaching vehicle or motorcycle is high, the pre-collision warning and pre-collision braking will operate. Depending on the intersection, assistance may not operate correctly.

∎ Acceleration Suppression at Low Speed
When driving at a low speed, if the accelerator pedal is strongly depressed and the system determines that there is a possibility of a collision, hybrid system output will be restrained or the brakes will be applied weakly to restrict acceleration. During operation, a buzzer will sound and a warning indicator and message will be displayed on the multi-information display.

WARNING
Pre-collision braking

• When the pre-collision braking function is operating, a large amount of braking force will be applied.
• The pre-collision braking function is not designed to hold the vehicle stopped. If the vehicle is stopped by pre-collision brake control, the driver should operate the brakes immediately 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-collision braking function from operating.
• 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 brake control.

Acceleration Suppression at Low Speed

If the steering wheel is being turned, the system may determine that the driver is taking evasive action and possibly prevent the Acceleration Suppression at Low Speed function from operating or possibly causing its operation to be canceled.
Emergency steering assist

• The emergency steering assist will be canceled when the system determines that lane departure prevention control has completed.
• Depending on operations performed by the driver, emergency steering assist may not operate or operation may be canceled.
  • If the accelerator pedal is depressed strongly, the steering wheel is turned heavily, the brake pedal is depressed, or the turn signal lever is operated, the system may determine that the driver is taking evasive action and the emergency steering assist may not operate.
  • While the emergency steering assist is operating, if the accelerator pedal is depressed strongly, the steering wheel is turned heavily, or the brake pedal is depressed, the system may determine that the driver is taking evasive action and emergency steering assist operation may be canceled.
  • While the emergency steering assist is operating, if the steering wheel is held or turned in the opposite direction of system operation, emergency steering assist operation will be canceled.

∎ Operating conditions of each function of the pre-collision system
The pre-collision system is enabled and the system determines that the possibility of a frontal collision with a detected object is high.
However, the system will not operate in the following situations:

• When the vehicle has not been driven a certain amount after a terminal of the 12- volt battery has been disconnected and reconnected

• When the shift lever is in R

• When the VSC OFF indicator is illuminated (only the pre-collision warning function will be operational)
  The following are the operational speeds and cancelation conditions of each function:

Changing the pre-collision setting

• The pre-collision system can be enabled/disabled through a customize setting.(Toyota car service centre | Book Car Service Appointment Online (toyotabharat.com))
  The system is enabled each time the power switch is turned to ON.

• When the system is disabled, the PCS warning light will illuminate and a message will be displayed on the multi-information display.

• The pre-collision setting can be changed on the customize settings.(Toyota car service centre | Book Car Service Appointment Online (toyotabharat.com))

• When the pre-collision warning timing is changed, the emergency steering assist timing will also be changed.

• When later is selected, the emergency steering assist will not operate in most cases.

• When the dynamic radar cruise control is operating, the pre-collision warning will operate at the earlier timing, regardless of the user setting.
