9
The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
● Multiport fuel injection system/sequential multiport fuel injection system
● Toyota Safety Sense P (if equipped)
● Dynamic radar cruise control system (if equipped)
● Cruise control system (if equipped)
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary meas ures or spe-
cial instructions regarding instal lation of a mobile two-way radio system.
The vehicle is equipped with sophisticated computers that will record certain
data, such as:
• Engine speed / Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the front camera (available only when certain safe ty sys-
tems are activated, which varies depending on the vehicle specifica-
tions).
The recorded data varies according to the vehicle grade level and options
with which it is equipped.
These computers do not record conversations or sounds, and only record
images outside of the vehicle in certain situations.
●Data Transmission
Your vehicle may transmit the data recorded in these computers to Toyota
without notification to you.

WARNING
■SRS airbag precautions
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the air bags. Such
accessories may prevent the side airbags from activating correc tly, disable
the system or cause the side airbags to inflate accidentally, r esulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the S RS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deplo yed, open a
door or window to allow fresh air in, or leave the vehicle if i t is safe to do
so. Wash off any residue as soon as possible to prevent skin ir ritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked , have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents t he sensor
from detecting the passenger’s weight properly. As a result, th e SRS front
airbags for the front passenger may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbag s
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, s ide and rear
pillars or roof side rails
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches or roof luggage carrier
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radio s and CD
players
● Modifications to your vehicle for a person with a physical disa bility

For safety and security
■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds GPS data to the already
included warranty-based Toyota roadside service.
Subscribers can press the “SOS” button to reach a Safety Connec t
response-center agent, who can he lp with a wide range of needs,
such as: towing, flat tire, fuel delivery, etc. For a description of the
Enhanced Roadside Assistance se rvices and their limitations,
please see the Safety Connect Te rms and Conditions, which are
available at Toyota.com in the United States, Toyotapr.com in
Puerto Rico and Toyota.ca in Canada.
Important! Read this informatio n before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-po wer
radio transmitter and receiver. I t 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 wi re-
less phones. Those guidelines are consistent with the safety stan-
dards previously set by the following U.S. and international
standards bodies.
● ANSI (American National Stand ards Institute) C95.1 [1992]
● NCRP (National Council on Radi ation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation
Protection) [1996]
Those standards were based on comprehensive and periodic eval-
uations of the relevant scienti fic literature. Over 120 scientists, engi-
neers, and physicians from unive rsities, 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 i n
addition to those standards.
