your language of ch oice when enrolling.
■When contacting the response center
You may be unable to contact the resp onse center if the network is busy.

light comes on for 2 seconds then turns off. Afterward, the green indicator light
comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage conditions:
●Green indicator light on = Active service

■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the system is
designed to automatically call the re sponse center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicl\
e occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, 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 location.

Important! Read this informatio
n before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power radio\
transmitter and receiver. It receives and also sends out radio frequency (RF)
signals.
In August 1996, the Federal Commu nications Commission (FCC) adopted
RF exposure guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with the safe ty standards previously set by the fol-
lowing U.S. and internat ional standards bodies.
●ANSI (American National Stan dards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation Protection)
[1996]
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physi-
cians from universities, and governme nt health agencies and industries
reviewed the available body of rese arch to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards.
