WARNING
■ For safe use
●Driving safely is solely the responsibility of the driver . Pay
careful attention to the surrounding conditions in order to ensure safe driving . The emergency driving stop system is designed to provide support in an emergency where it is difficult for the driver to continue driving , such as if they have had
a medical emergency . It is not designed to support driving while drowsy or in poor physical
health , or inattentive driving .
● Although the emergency driving stop system is designed to decelerate the vehicle within its lane to help avoid or help reduce the impact of a collision if the system determines that it is difficult for the driver to continue driving , its effectiveness may change according to various conditions . Therefore , it may not always be able to achieve the same level of performance . Also , if the operating conditions are not met , this function will not operate .
●After the emergency driving
stop system operates , if driving becomes possible again , immediately begin driving again or , if
necessary , park the vehicle on the shoulder of the road and set a warning reflector and flare to
warn other drivers of your stopped vehicle .
● After this system operates , passengers should attend to the driver as necessary and take appropriate hazard prevention measures , such as moving to a place where safety can be ensured , such as the shoulder of the road or behind a guardrail .
● This system detects the condition of the driver through the operation of the steering wheel . This system may operate if the driver is aware but intentionally and continuously does not operate the vehicle . Also , the system may not operate if it cannot
determine that the driver is not responsive , such as if they are leaning on the steering wheel .
●Situations in which the driver monitor may not operate properly : �P . 267

If the system determines the driver is not responsive , it will operate in control state “ deceleration stop phase ” and “ stop hold phase ” and decelerate and stop the vehicle . It will then operate continuously in “ stop hold phase ”.
