For safety and security
Front impact sensors
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 brakes and st op lights will be
controlled automatically. ( P.249)
●The interior lights will turn on auto-
matically. ( P.272)
●The emergency flashers will turn
on automatically. ( P.348)
●Fuel supply to the engine will be
stopped. (P.355)
●For Safety Connect subscribers, if
any of the followin g 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 2 )
• 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, such as a parked vehicle or sign
pole, which can move or deform
on impact
• If the vehicle is involved in an underride collision, such as a colli-
sion in which the front of the vehi-
cle “underrides”, or goes under,
the bed of a truck
●Depending on the type of collision,
it is possible that only the seat belt
pretensioners will activate.

461-1. For safe use
Exhaust gas precau-
tions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in
the vehicle even when the trunk
lid is closed, open the windows
and have the vehicle inspected
at your Toyota dealer as soon
as possible.
■When parking
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
engine.
●Do not leave the vehicle with
the engine on for a long time.
If such a situation cannot be
avoided, park the vehicle in an
open space and ensure that
exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running
in an area with snow build-up,
or where it is snowing. If snow-
banks build up around the vehi-
cle while the engine is running,
exhaust gases may collect and
enter the vehicle.
■Exhaust pipe
The exhaust system needs to be
checked periodically. If there is a
hole or crack caused by corro-
sion, damage to a joint or abnor-
mal exhaust noise, be sure to
have the vehicle inspected and
repaired by your Toyota dealer.

741-3. Emergency assistance
busy.
When the engine switch is
turned to ON, 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 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 Customer Experi-
ence 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-Con-
nect-equipped vehicle location
data may, under certain circum-
stances, be shared with third
parties to locate your vehicle.

■Exposure to radio fre-
quency 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 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).
