Emergency Assist combines the functions of Lane Assist and ACC in a new assistance system. As soon as the sensors detect no steering, braking or acceleration activity on the part of the driver, the system activates various escalation stages. Initially, the system attempts to wake the driver by steering jerks and finally an emergency stop is initiated. The hazard warning flashers are activated automatically and the car completes some slight steering maneuvers to draw the attention of other road users to the hazardous situation. ACC prevents collisions with the traffic ahead. Finally, the system brakes the vehicle continuously to a standstill.
