■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatical ly 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 co mmunicate, the agent automatically
treats the call as an emergency, co ntacts the nearest emergency ser-
vices provider to describe the situa tion, and requests that assistance
be sent to the location.
