Pre-Collision Braking System operation
When there is an obstacle in the forward direction during driving, the system activates in the
following sequence in order to warn the driver, activate braking control, and active the brake
lights.
(1) 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 meter display and the multi function 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.
(2) 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 meter display and the multi
function display illuminate to warn the driver, and braking control is activated. 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.
(3) Second 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. If, despite any eva-
sive action taken by the driver, the system subsequently determines that a collision is
unavoidable, braking control is continued.
When the vehicle stops, a buzzer sounds three short beeps and a single long beep. The
automatic braking function is cancelled approximately 2 seconds after the vehicle stops and
the vehicle starts creeping forward gradually.
