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 vehicle 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. ■
Stolen Vehicle Location
If your vehicle is stolen, Safety Conn ect can work with local authorities to
assist them in locating and recovering the vehicle. After filing a police report,

service.

RX350/RX350L_U 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. ■
