■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
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts 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) in the United
States, 1-877-539-8777 in Puerto
Rico or 1-800-265-3987 in Canada,
and follow the prompts for Safety Con-
nect to initiate this service.
In addition to assisting law enforce-
ment with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle
location data may, under certain cir-
cumstances, be shared with third par-
ties to locate your vehicle. Further
information 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 neces-
sary assistance 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” but-
ton 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, which are available at
Safety Connect services

Important! Read this information about
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 Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.
 ANSI (American National Stan-
dards Institute) C95.1 [1992]
 NCRP (National Council on Radia-
tion Protection and Measurement)
Report 86 [1986]
 ICNIRP (International Commission
on Non-Ionizing Radiation Protec-
tion) [1996]
Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over
120 scientists, engi neers, and physi-
cians from universi ties, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com- plies with the FCC guidelines in addi-
tion to those standards.
