When the engine switch is turned to IGNITION ON mode, the red indi-
cator light comes on for 2 seconds th en turns off. Afterward, the green
indicator light comes on, indicat ing that the service is active.
The following indicator light patter ns indicate specific system usage con-
ditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunction
(contact your Lexus dealer)
●No indicator light (off) = Safety Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicl e’s location and attempts to speak
with the vehicle occupants to assess the level of emergency. If the occu-
pants are unable to communicate, th e agent automatically treats the
call as an emergency, contacts th e nearest emergency services pro-
vider to describe the situation, and re quests that assistance be sent to
the location.

■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 fre-
quency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guid elines with safety levels for mobile wireless
phones. Those guidelines are consistent with the safety standards previ-
ously set by the following U.S. and international standards bodies.
●ANSI (American National Standards Institute) C95.1 [1992]
●NCRP (National Council on Radi ation Protection and Measure-
ment) Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on comprehensive and periodic evalua-
tions of the relevant scientific litera ture. Over 120 scientists, engineers,
and physicians from universities, and government health agencies and
industries reviewed the available body of research to develop the ANSI
Standard (C95.1).
The design of Safety Connect co mplies with the FCC guidelines in
addition to those standards.
