Manual Emergency Call

In the event of an emergency, the driver or passengers can press the emergency call button. The current vehicle position is then displayed in the Control Display along with a message indicating that the emergency call has been placed.

The service provider sets up a voice connection to the vehicle and receives confirmation of the emergency call. Once the voice connection to the provider has been set up, the green button display flashes. The rescue services are then notified and this is indicated on the Control Display.
