Pre-Collision Braking System
Pre-Collision Braking System operation
When there is an obstacle in front of you during driving, the system activates in the following
sequence in order to warn the driver, activate braking control, and active the brake lights.
Following Distance Warning:
When the system determines that there is a risk of collision, a buzzer sounds repeated short
beeps and the indicators on the combination meter display illuminate to warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is not set.
When the driver depresses the brake pedal to decelerate and achieves a suitable following
distance, the warning is canceled.
First Braking and Warning:
When the system determines that there is a high risk of collision with an obstacle in front, a
buzzer sounds repeated short beeps and the indicators on the combination meter display
illuminate to warn the driver, and braking control is activated and the engine output, in some
situations, is also controlled. If the system determines that the amount of evasive action
(braking, steering, etc.) taken by the driver has reduced the risk of collision, braking activation is canceled.
Secondary Braking and Warning:
If the system then determines that the risk of collision is extremely high, the buzzer changes
to a continuous beeping sound and stronger braking control is activated. Despite any evasive action taken by the driver, if the system subsequently determines that a collision is
unavoidable, braking and engine output are controlled by the system.
Once the vehicle has come to a stop, the system will release the brake pedal control. At this
time you will need to manually apply the brake.
Vehicle restart:
After the vehicle is completely stopped by the pre-collision braking system, the brake will be
slightly released 2 seconds after the vehicle stops. After sounding a short tone “beep, beep,
ding”, the vehicle starts creeping. To stop the vehicle completely, you will need to manually
apply the brake.
