For safety and security
■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 (steering 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. The 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. 85)
● The emergency flashers will turn on automatically. (P. 568)
● Vehicles with “ERA-GLONASS/EVAK”: If any of the following situations
occur, the system is designed to send an emergency call* to the “ERA-
GLONASS/EVAK control 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 auto-
matically treats the call as an emergency and helps to dispatch the
necessary emergency services. ( P. 74)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
• The vehicle is involved in a rollover accident.
*: In some cases, the call cannot be made. ( P. 7 7 )
■ SRS airbag deployment conditions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 20 -
30 km/h [12 - 18 mph] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
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 collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
● Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.

Microphone
“SOS” button*
Indicator lights
*: This button is intended for commu-
nication with the ERA-GLONASS/
EVAK system operator.
Other SOS buttons available in
other systems of a motor vehicle do
not relate to the device and are not
intended for communication with
the ERA-GLONASS/EVAK system
operator.
1: If equipped
2: Operates within regions offering emergency notification services. Ask any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer for details.
3: The system name differs depending on the country.
The Emergency Call system is a device installed on a vehicle to
determine its location and movement direction (using GLONASS
[Global Navigation Satellite System] and GPS [Global Position-
ing System] signals), and ensure the generation and transmis-
sion of vehicle information (in a nonadjustable form) in case of
traffic accidents or other incidents on motor roads in the coun-
tries offering emergency notification services. In addition, it
ensures two-way voice communication between the vehicle and
an ERA-GLONASS/EVAK system operator through cellular net-
works (GSM).
Automatic Emergency Calls (via Automatic Collision Notifica-
tion) and manual Emergency Calls (by pressing the “SOS” but-
ton) can be made to the ERA-GLONASS/EVAK control center.
This service is mandatory according to the technical regulations
of the Customs Union.

For safety and security
■Automatic Emergency Calls
If any airbag deploys, the system is designed to automatically call
the ERA-GLONASS/EVAK control center.* The answering operator
receives the vehicle’s location, the time of the incident and the vehi-
cle VIN, and attempts to speak with the vehicle occupants to
assess the situation. If the occupants are unable to communicate,
the operator automatically treats the call as an emergency and con-
tacts the nearest emergency services provider (112 system etc.) to
describe the situation and request that assistance be sent to the
location.
*: In some cases, the call cannot be made. ( P. 7 7 )
■Manual Emergency Calls
In the event of an emergency, press the “SOS” button to call the
ERA-GLONASS/EVAK control center.* The answering operator will
determine your vehicle’s location, assess the situation, and dis-
patch the necessary assistance required.
If you accidentally press the “SOS” button, tell the operator that you are
not experiencing an emergency.
*: In some cases, the call cannot be made. ( P. 7 7 )

WARNING
■When the Emergency Call may not be made
● It may not be possible to make Emergency Calls in any of the following sit-
uations. In such cases, report to emergency services provider (112 system
etc.) by other means such as nearby public phones.
• Even when the vehicle is in the cellular phone service area, it may be
difficult to connect to the ERA-GLONASS/EVAK control center if the
reception is poor or the line is busy. In such cases, even though the sys-
tem attempts to connect to the ERA-GLONASS/EVAK control center,
you may not be able to connect to the ERA-GLONASS/EVAK control
center to make Emergency Calls and contact emergency services.
• When the vehicle is out of the cellular phone service area, the Emer-
gency Calls cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator
lights, microphone, speaker, DCM, antenna, or any wires connecting
the equipment) is malfunctioning, damaged or broken, the Emergency
Call cannot be made.
• During an Emergency Call, the system makes repeated attempts to
connect to the ERA-GLONASS/EVAK control center. However, if it can-
not connect to the ERA-GLONASS/EVAK control center due to poor
radio wave reception, the system may not be able to connect to the cel-
lular network and the call may finish without connecting. The red indica-
tor light will blink for approximately 30 seconds to indicate this
disconnection.
• This device may not function if a shock is applied to it.
● If the 12-volt battery’s voltage decreases or there is a disconnection, the
system may not be able to connect to the ERA-GLONASS/EVAK control
center.
■ When the Emergency Call system is replaced with a new one
The Emergency Call system should be registered. Contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

Hybrid system precautions
The illustration is an example for explanation and may differ from the
actual item.
Take care when handling the hybrid system, as it is a high volt-
age system (about 600 V at maximum) as well as contains parts
that become extremely hot when the hybrid system is operating.
Obey the warning labels attached to the vehicle.

861-4. Hybrid system
PRIUS_OM_OM47F32E_(EE)
■If a warning light comes on, a warning message is displayed, or the
12-volt battery is disconnected
The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light ( P. 583) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
7.5 L [2.0 gal., 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)
■ Electromagnetic waves
● High voltage parts and cables on hybrid vehicles incorporate electromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.
■ Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100
(Battery electric vehicle safety).
