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 information abou t exposure to radio frequency signals
before using Safety Connect;
The Safety Connect system installed in your vehicle is a low-power radio trans-
mitter and receiver. It receives and also sends out radio frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC) adopted RF
exposure guidelines with safety levels for mobile wireless phones. Those guide-
lines are consistent with the safety standards previously set by the following U.S.
and international 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 literatur e. Over 120 scientists, engineers, and physicians from
universities, and government health agen cies and industries reviewed the avail-
able body of research to deve lop the ANSI Standard (C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards.
