■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 communicate, the agent automati-
cally treats the call as an emergency, contacts the nearest emer-
gency services provider to descri be the situation, and requests that
assistance be sent to the location.

ities to assist them in locating a nd recovering the vehicle. After filing
a police report, call the Safety Connect response center at 1-800-
