ditions:

■Automatic Collision Notification
In case of either airbag deployment or severe collision, the system is
designed to automatically call the response center. The responding
agent receives the vehicle’s location and attempts to speak with the
vehicle occupants to assess the level of emergency. If the occupants
are unable to communicate, the agent automatically treats the call as
an emergency, contacts the nearest emergency services provider to
describe the situation, and requests that assistance be sent to the loca-
tion.
