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 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 . The Following Distance Warning operates when Adaptive Cruise Control is not activated . 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 , an alert sounds repeated short beeps and the indicators on the combination meter display and the center information display illuminate 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 activation 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 unavoidable , 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 .
