lators should ma intain a reason-
able distance between
themselves and the Bluetooth
®
antennas. The radio waves may
affect the operation of such

●Exposure to radio frequency sig-
nals:
The Toyota audio multimedia sys-
tem installed in your vehicle
includes a low power radio trans-
mitter and receiver. The system
receives and also sends out radio
frequency (RF) signals.
●In August 1996, the Federal Com-
munications Commission (FCC)
adopted RF exposure guidelines
with safety levels for mobile wire-
less phones. Those guidelines are
consistent with the safety stan-
dards previously set by both U.S.
and international standards bod-
ies.
• ANSI (American National Stan- dards Institute) C95.1 [1992]
• NCRP (National Council on Radi- ation Protection and Measure-
ment) Report 86 [1986]
• ICNIRP (International Commis- sion on Non-Ionizing Radiation
Protection) [1996]
●These standards are based on
comprehensive and periodic eval-
uations of the relevant scientific lit-
erature. Over 120 scientists,
engineers, and physicians from
universities, government health
agencies, and industry reviewed
the available body of research to
develop the ANSI Standard
(C95.1).
●The design of Toyota audio multi-
media system complies with the
FCC guidelines in addition to
those standards.
●Contact with the Toyota response
center is dependent upon the
telematics device being in opera-
tive condition, cellular connection
availability, navigation map data,
and GPS satellite signal recep-
tion, which can limit the ability to
reach the Toyota response center
or receive support. Enrollment and
Telematics Subscription Service
Agreement required. A variety of
subscription terms are available;
charges vary by su bscription term
selected.
●The Toyota response center offers
support in mult iple languages.
●Select Safety Connect-sub-
scribed vehicles are capable of
communicating vehicle informa-
tion. Please see the terms and
conditions for additional details.
Owners who do not wish to have
their vehicle transm it this informa-
tion can opt out at the time of
enrollment or by calling 1-800-
331-4331 in the United States, 1-
888-869-6828 in Canada, and 1-
877-855-8377 in Puerto Rico, and
following the prompts for Safety
Connect.
●For further details about the ser-
vice, contact your Toyota dealer.
●Toyota audio multimedia func-
tions are not subject to section
255 of the Telecommunications
Act and the system is not TTY
