381-1. For safe use
Owners Manual_USA_M0C052_en
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. 7 9 )
●All of the doors will be unlocked.
( P.114)
●The brakes and st op lights will be
controlled automatically. ( P.375)
●The interior lights will turn on auto-
matically. ( P.412)
●The emergency flashers will turn
on automatically. ( P.494)
●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. 6 8 )
• 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

For safety and security
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.507)
go off. If there is only a small
amount of fuel, th e hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 21.9 L
[5.8 gal., 4.8 Imp. gal.] when the
vehicle is on a level surface. This
value may vary whe n the vehicle is
on a slope. Add extra fuel when the
vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
Hybrid Electric Vehicles incorpo-
rate electromagnetic shielding,
and therefore emi t approximately
the same amount of electromag-
netic waves as conventional gaso-
line powered vehicles or home
electronic appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Hybrid battery (tr action battery)
The hybrid battery (traction battery)
has a limited service life. The lifes-
pan of the hybrid battery (traction
battery) can change in accordance
with driving style and driving condi-
tions.
■Starting the hybrid system in an
extremely cold environment
When the hybrid battery (traction
battery) is extremely cold (below
approximately -31°F [-35°C]) under
the influence of t he outside tem-
perature, it may no t be possible to
start the hybrid system. In this case,
try to start the hybrid system again
after the temperature of the hybrid
battery increases due to the outside
temperature increase etc.
WARNING
■High voltage precautions
This vehicle has high voltage DC
and AC systems as well as a 12-
volt system. DC and AC high volt-
age is very dangerous and can
cause severe burns and electric
shock that may result in death or
serious injury.
●Never touch, disassemble,
remove or replace the high volt-
age parts, cables or their con-
nectors.
●The hybrid system will become
hot after starting as the system
uses high voltage. Be careful of
both the high voltage and the
high temperature, and always
obey the warning labels
attached to the vehicle.
●Never try to open the service
plug access hole located under
the right side o f the rear seat.
The service plug is used only
when the vehicle is serviced
and is subject to high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Stop the vehicle in a safe place
to prevent subsequent acci-
dents. While depressing the
brake pedal, apply the parking
brake and shift the shift lever to
P to stop the hybrid system.
Then, slowly release the brake
pedal

WARNING
■If a safety system warning
light does not come on
Should a safety system light such
as the ABS and SRS warning light
not come on when you start the
hybrid system, this could mean
that these system s are not avail-
able to help protect you in an acci-
dent, which could result in death
or serious injury. Have the vehicle
inspected by you r Toyota dealer
immediately if this occurs.
