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 an interruption screen is displayed on the combination meter display 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 an interruption screen is displayed on the combination meter display 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 , the system continues to control braking and engine output . 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 : When the vehicle is completely stopped by the automatic braking system , a short tone “ 3 short beeps and 1 long beep ” will sound and braking will be gradually released and the vehicle will start creeping . To stop the vehicle completely , depress the brake pedal after the vehicle has stopped .
