This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will
assist in understanding how a
vehicle’s systems performed.
The EDR is designed to record
data related to vehicle dynamics
and safety systems for a short
period of time, typically 30 sec-
onds or less. The EDR in this vehicle is
designed to record such data
as:
• How various systems in your
vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened;
• How far (if at all) the driver was depressing the accelera-
tor and/or brake pedal; and,
• How fast the vehicle was trav- eling.
These data can help provide a
better understanding of the cir-
cumstances in which crashes
and injuries occur.
NOTE: EDR data are recorded
by your vehicle only if a non-triv-
ial crash situation occurs; no
data are recorded by the EDR
under normal driving conditions
and no personal data (e.g.,
name, gender, age, and crash
location) are recorded. How-
ever, other parties, such as law
enforcement, could combine the
EDR data with the type of per-
sonally identifying data rou-
tinely acquired during a crash
investigation.
To read data recorded by an
EDR, special equipment is
required, and access to the
vehicle or the EDR is needed. In
addition to the vehicle manufac-
turer, other parties, such as law
enforcement, that have the spe-
cial equipment, can read the

For safety and security
Driver’s seat bel t buckle switch
Driver’s seat position sensor
Front passenger’s seat belt buckle switch
Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation includes crash sever-
ity and occupant information. As the airbags deploy, a chemical
reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the front seats,
parts of the front and rear pillars,
and roof side rails, may be hot for
several minutes. T he airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped
and fuel supply to the engine will
be stopped. ( P. 8 1 )
●All of the doors will be unlocked.
( P.116)
●The brakes and st op lights will be
controlled automatically. ( P.383)
●The interior lights will turn on auto-
matically. ( P.420)
●The emergency flashers will turn
on automatically. ( P.502)
●For Safety Connect subscribers, if
any of the following situations occur, the system is designed to
send an emergency call to the
response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. (
P. 7 0 )
• An SRS airbag is deployed.
• A seat belt pretensioner is acti- vated.
• The vehicle is involved in a severe rear-end collision.
■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy
in the event of an impact that
exceeds the set threshold level
(the level of forc e corresponding
to an approximately 12 - 18 mph
[20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform).
However, this threshold velocity will
be considerably higher in the follow-
ing situations:
• If the vehicle strikes an object,

When the power switch is turned
to ON, the red indicator light
comes on for 2 seconds then
turns off. Afterward, the green
indicator light comes on, indicat-
ing that the service is active.
The following indicator light pat-
terns indicate specific system
usage conditions:
Green indicator light on =
Active service
 Green indicator light flashing
= Safety Connect call in pro-
cess
 Red indicator light (except at
vehicle start-up) = System
malfunction (contact your Toy-
ota dealer)
 No indicator light (off) =
Safety Connect service not
active
■Automatic Collision Notifi-
cation
In case of either airbag deploy-
ment or severe rear-end colli-
sion, 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 emergency. If the occu- pants are unable to communi-
cate, the agent automatically
treats the call as an emergency,
contacts the nearest emer-
gency 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 1-800-331-
4331 in the United States, 1-
877-855-8377 in Puerto Rico or
1-888-869-6828 in Canada, 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 information is available
at Toyota.com.
■Emergency Assistance But-
ton (“SOS”)
In the event of an emergency on
the road, push the “SOS” button

Important! Read this informa-
tion about exposure to radio fre-
quency signals before using
Safety Connect;
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 following 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 Com-
mission on Non-Ionizing Radi-
ation Protection) [1996]
Those standards were based on
comprehensive and periodic
evaluations of the relevant sci-
entific literature. Over 120 scien-
tists, engineers, and physicians
from universities, and govern-
ment health agencies and
industries reviewed the avail-
able body of research to
develop the ANSI Standard
(C95.1).
The design of Safety Connect
complies with the FCC guide-
lines in addition to those stan-
dards.
