Foreword

In June 2011, Toyota released the 2012 Prius V gasoline-electric hybrid
vehicle in North America. To educate and assist emergency responders
in the safe handling of the Prius V hybrid technology, Toyota published
this Prius V Emergency Response Guide.

The Prius V is based on the 3rd generation Toyota Prius. While many
features from the Toyota Prius and Prius V are similar, emergency
responders should recognize and understand the new, updated features
of the Prius V covered in this guide.

High voltage electricity powers the electric motor, generator, air
conditioning compressor and inverter/converter. All other automotive
electrical devices such as the headlights, radio, and gauges are powered
from a separate 12 Volt auxiliary battery. Numerous safeguards have
been designed into the Prius V to help ensure the high voltage,
approximately 201.6 Volt, Nickel Metal Hydride (NiMH) Hybrid
Vehicle (HV) battery pack is kept safe and secure in an accident.

The Prius V utilizes the following electrical systems:

• Maximum 650 Volts AC

• Nominal 201.6 Volts DC

• Maximum 27 Volts AC

• Nominal 12 Volts DC

Prius V Features:

• A boost converter in the inverter/converter that boosts the available

voltage to the electric motor to 650 Volts.

• A high voltage Hybrid Vehicle (HV) battery pack rated at 201.6

Volts.

• A high voltage motor driven Air Conditioning (A/C) compressor

rated at 201.6 Volts.

• A body electrical system rated at 12 Volts, negative chassis ground.

• Supplemental Restraint System (SRS) - dual stage frontal airbags, a

driver knee airbag, front seat side airbags, side curtain airbags and
front seat belt pretensioners.

• An Electric Power Steering (EPS) assist motor rated at 27 Volts.

High voltage electrical safety remains an important factor in the
emergency handling of the Prius V Hybrid Synergy Drive. It is
important to recognize and understand the disabling procedures and
warnings throughout the guide.

Additional topics in the guide include:

• Prius V identification.

•

Major Hybrid Synergy Drive component locations and descriptions.

•

Extrication, fire, recovery, and additional emergency response
information.

•

Roadside assistance information.

2012 Model Year Prius V

About the Prius V

The Prius V 5-door wagon joins the Prius, Camry Hybrid and
Highlander Hybrid as a hybrid model for Toyota. Hybrid Synergy
Drive means that the vehicle contains a gasoline engine and an electric
motor for power. The two hybrid power sources are stored on board
the vehicle:

1. Gasoline stored in the fuel tank for the gasoline engine.

2. Electricity stored in a high voltage Hybrid Vehicle (HV) battery pack
for the electric motor.

The result of combining these two power sources is improved fuel
economy and reduced emissions. The gasoline engine also powers an
electric generator to charge the battery pack; unlike a pure all electric
vehicle, the Prius V never needs to be charged from an external electric
power source.

Depending on the driving conditions one or both sources are used to
power the vehicle. The following illustration demonstrates how the
Prius V operates in various driving modes.

n

During light acceleration at low speeds, the vehicle is powered by
the electric motor. The gasoline engine is shut off.

o

During normal driving, the vehicle is powered mainly by the
gasoline engine. The gasoline engine also powers the generator to
charge the battery pack.

p

During full acceleration, such as climbing a hill, both the gasoline
engine and the electric motor power the vehicle.

q

During deceleration, such as when braking, the vehicle regenerates
kinetic energy from the front wheels to produce electricity that
charges the battery pack.

r

While the vehicle is stopped, the gasoline engine and electric motor
are off, however the vehicle remains on and operational.

Prius V Identification

In appearance, the 2012 model year Prius V is a 5-door wagon. Exterior,
interior, and engine compartment illustrations are provided to assist in
identification.

The alphanumeric 17 character Vehicle Identification Number (VIN) is
provided in the front windshield cowl, passenger side floor and on the
driver side B pillar.

Example VIN: JTDZN3EU0C3000101

A Prius V is identified by the first 8 alphanumeric characters
JTDZN3EU.

Smart Key System

The Prius V smart key system consists of a smart key transceiver that
communicates bi-directionally, enabling the vehicle to recognize the
smart key in proximity to the vehicle. Once recognized, the smart key
will allow the user to lock and unlock the doors without pushing smart
key buttons, and start the vehicle without inserting it into an ignition
switch.

Smart key features:

•

Passive (remote) function to lock/unlock the doors and start the
vehicle.

•

Wireless transmitter buttons to lock/unlock all 5 doors.

•

Hidden metal cut key to lock/unlock the doors.

Door (Lock/Unlock)

There are several methods available to lock/unlock the doors.

• Pushing the smart key lock button will lock all doors. Pushing the smart

key unlock button once unlocks the driver door, twice unlocks all doors.

• Touching the sensor on the backside of the driver door exterior handle, with

the smart key in proximity to the vehicle, unlocks the driver door. Touching
the sensor on the backside of the front passenger door exterior handle, with
the smart key in proximity to the vehicle, unlocks all doors. Touching the
lock touch sensor on either front door, or pushing the back door lock button
will lock all doors.

• Inserting the hidden metal cut key in the driver door lock and turning

clockwise once unlocks the driver door, twice unlocks all doors. To lock
all doors turn the key counter clockwise once. Only the driver door
contains an exterior door lock for the metal cut key.
