When the engine switch is turned to
IGNITION ON mode, the red indicator
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
●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 vehicle’s location and atte mpts 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 Connect can work with local authorities to
assist them in locating and recovering the vehicle. After filing a police report,
call the Safety Connect response center at 1-800-25-LEXUS (1-800-255-
3987) and follow the prompts for Safety Connect to initiate this service.
In addition to assisting law enforcement with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle location data may, under certain circum-
stances, be shared with third parties to locate your vehicle. Further informa-
tion is available at Lexus.com.
■Emergency Assistance Button (“SOS”)
In the event of an emergency on the road, push the “SOS” button to reach the
Safety Connect response center. The answering agent will determine your
vehicle’s location, assess the emergency, and dispatch the necessary assis-
tance required.
If you accidentally press the “SOS” button, tell the response-center agent that you
are not experiencing an emergency.

■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds GPS data to the already included war-
ranty-based Lexus roadside service.
Subscribers can press the “SOS” button to reach a Safety Connect response-
center agent, who can help with a wide range of needs, such as: towing, flat
tire, fuel delivery, etc. For a description of the Roadside Assistance services
and their limitations, please see the Safety Connect Terms and Conditions,

Important! Read this information 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 Communications Commission (FCC) adopted
RF exposure guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with the safety standards previously set by the fol-
lowing U.S. and international standards bodies.
●ANSI (American National Standards 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 government health agencies and industries
reviewed the available body of research to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies with the FCC guidelines in addition to
those standards.
