Applies to: vehicles with emergency assist
The emergency assist takes over control of the vehicle in certain situations and can help to prevent accidents. It is an extension of the active lane assist and can use the functions of the adaptive cruise control and pre sense front systems ►. The emergency assist is activated when it detects that the driver has stopped steering the vehicle.
Functions of the emergency assist
The emergency assist monitors the steering activity of the driver. It detects if the driver is inactive and gives repeated visual and audible warnings as well as brake jolts prompting the driver to take proactive control of the vehicle again. The hazard warning lights are also switched on when the first sharp brake jolt is given below a speed of 80 km/h1).
If the driver does not take over, the system intervenes by steering the vehicle (within the limitations of the system) to keep it in lane, and by applying the brakes until the vehicle has stopped*. In addition, the warning lamp and a message are displayed.
