Pre-Collision Braking System
44
When there is an obstacle in front of you during driving, the system activates in the following
sequence in order to warn the driver and to activate braking control and the brake lights.
Following Distance Warning:
When the system determines that there is a risk of collision, an alert sounds repeated short
beeps and the indicators on the combination meter display illuminate to warn the driver.
When the driver depresses the brake pedal to decelerate and achieves a suitable following
distance, the warning is canceled.
The Following Distance Warning operates when Adaptive Cruise Control is not activated.
First Braking and Warning:
When the system determines that there is a high risk of collision with an obstacle in front, an
alert sounds repeated short beeps and the indicators on the combination meter display illu-
minate to warn the driver. Braking control may be activated and in some situations, engine
output may also be 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 activa-
tion is canceled.
Secondary Braking and Warning:
If the system then determines that the risk of collision is extremely high, the alert 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 unavoid-
able, braking and engine output are controlled by the system.
When the vehicle is stopped by secondary braking, the driver should depress the brake
pedal in order to ensure that the vehicle stays stopped.
