WARNING
■ When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as
long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
■ When a child restraint system is not installed on the front passenger
seat
Ensure that the airbag manual on-off system is set to “ON”.
If it is left off, the airbag will not deploy in the event of an accident, which
may result in serious injury or even death.

*: 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.

When the power switch is turned to ON mode, the red indicator light
will illuminate for 10 seconds and then the green indicator light will illu-
minate, indicating that the system is enabled. The indicator lights indi-
cate the following:
● If the green indicator light illuminates and stays on, the system is
enabled.
● If the green indicator light flashes twice per second, an automatic or
manual Emergency Call is being made.
● If no indicator lights illuminate, the system is not enabled.
● If the red indicator light illuminates at any time other than immedi-
ately after the power switch is turned to ON mode, the system may
be malfunctioning or the backup battery may be depleted. Contact
any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
● If the red indicator light blinks for approximately 30 seconds during
an Emergency Call, the call has been disconnected or the cellular
network signal is weak.
The backup battery has lifespan of at least 3 years.
A test mode is provided for to check the performance of the Emer-
gency Call system. To test the device, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

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.

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).

Immobilizer system
The indicator light flashes after
the power switch has been turned
off to indicate that the system is
operating.
The indicator light stops flashing
after the power switch has been
turned to ACCESSORY or ON
mode to indicate that the system
has been canceled.
■ System maintenance
The vehicle has a maintenance-free type immobilizer system.
■ Conditions that may cause the system to malfunction
● If the grip portion of the key is in contact with a metallic object
● If the key is in close proximity to or touching a key registered to the security
system (key with a built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent
the hybrid system from starting if a key has not been previously
registered in the vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehi-
cle.
This system is designed to help prevent vehicle theft but does not
guarantee absolute security against all vehicle thefts.
NOTICE
■ To ensure the system operates correctly
Do not modify or remove the system. If modified or removed, the proper
operation of the system cannot be guaranteed.

NOTICE
■ To ensure the intrusion sensor functions correctly
● Installing accessories other than genuine Toyota parts or leaving objects
between the driver’s seat and front passenger’s seat may reduce the
detection performance.
● To ensure that the sensors operate
properly, do not touch or cover them.
● Do not spray air fresheners or other
products directly into the sensor holes.
