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.

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.
nDuring light acceleration at low speeds, the vehicle is powered by
the electric motor. The gasoline engine is shut off.
oDuring normal driving, the vehicle is powered mainly by the
gasoline engine. The gasoline engine also powers the generator to
charge the battery pack.
pDuring full acceleration, such as climbing a hill, both the gasoline
engine and the electric motor power the vehicle.
qDuring deceleration, such as when braking, the vehicle regenerates
kinetic energy from the front wheels to produce electricity that
charges the battery pack.
rWhile the vehicle is stopped, the gasoline engine and electric motor
are off, however the vehicle remains on and operational.

Smart Key System (Continued)
Vehicle Starting/Stopping
The smart key has replaced the conventional metal cut key, and the power
button with an integral status indicator light has replaced the ignition switch.
The smart key only needs to be in proximity to the vehicle to allow the system
to function.
•With the brake pedal released, the first push of the power button operates
the accessory mode, the second push operates the ignition-on mode, and the
third push turns the ignition off again.
Ignition Mode Sequence (brake pedal released):
•Starting the vehicle takes priority over all other ignition modes and is
accomplished by depressing the brake pedal and pushing the power button
once. To verify the vehicle has started, check that the power button status
indicator light is off and the READY light is illuminated in the instrument
cluster.
•If the internal smart key battery is dead, use the following method to start
the vehicle.
1. Touch the Toyota emblem side of the smart key to the power button.
2. Within the 10 seconds after the buzzer sounds, push the power button
with the brake pedal depressed (the READY light will illuminate).
•Once the vehicle has started and is on and operational (READY-ON), the
vehicle is shut off by bringing the vehicle to a complete stop and then
depressing the power button once.
•To shut off the vehicle before coming to a stop in an emergency, push and
hold down the power button for more than 3 seconds. This procedure may
be useful at an accident scene in which the READY indicator is on, park
(P) cannot be selected, and the drive wheels remain in motion.

Electronic Shift Selector
The Prius V electronic shift selector is a momentary select shift-by-wire
system that can be used to select reverse (R), neutral (N), drive (D), or
engine brake (B) states.
•These states may only be selected while the vehicle is on and operational
(READY-on), except for neutral (N) which may also be selected while in
the ignition-on mode. After R, N, D, or B is selected, the transaxle remains
in that state, identified on the instrument cluster, but the shift selector
returns to the home position. To select neutral (N), it is necessary to hold
the shift selector in the N position for approximately 0.5 seconds.
•Unlike a conventional vehicle, the electronic shift selector does not contain
a park (P) position. Instead, a separate Pswitch located below the shift
selector selects park (P).
•When the vehicle is stopped, regardless of shift state, the electro-
mechanical parking lock pawl is engaged to lock the transaxle into park (P)
by either pressing the P switch or pressing the power button to shut off the
vehicle.
•Being electronic, the shift selector and park (P) systems depend on the low
voltage 12 Volt auxiliary battery for power. If the 12 Volt auxiliary battery
is discharged or disconnected, the vehicle cannot be started and cannot be
shifted into or out of park (P). There is no manual override except to
reconnect the auxiliary battery or jump start the vehicle, refer to Jump
Starting on page 31.

Hybrid Synergy Drive Operation
Once the READY indicator is illuminated in the instrument cluster, the
vehicle may be driven. However, the gasoline engine does not idle like a
typical automobile and will start and stop automatically. It is important
to recognize and understand the READY indicator provided in the
instrument cluster. When lit, it informs the driver that the vehicle is on
and operational even though the gasoline engine may be off and the
engine compartment is silent.
Vehicle Operation
•With the Prius V, the gasoline engine may stop and start at any time while
the READY indicator is on.
•Never assume that the vehicle is shut off just because the engine is off.
Always look for the READY indicator status. The vehicle is shut off when
the READY indicator is off.
•The vehicle may be powered by:
1. The electric motor only.
2. The gasoline engine only.
3. A combination of both the electric motor and the gasoline engine.
•The vehicle computer determines how the vehicle operates in order to
improve fuel economy and reduce emissions. Three features on the 2011
Prius V are EV (Electric Vehicle) mode, PWR (Power) mode and ECO
(Economy) mode:
1. EV Mode: When activated, and certain conditions have been met,
the vehicle operates with the electric motor powered by the HV
battery.
2. ECO Mode: When activated, this mode helps enhance fuel
economy on trips that involve frequent braking and acceleration.
3. PWR Mode: When activated, Power mode optimizes acceleration
feel by increasing the power output more quickly at the beginning
of accelerator pedal operation.

that contains sealed Nickel Metal Hydride (NiMH) battery modules.
HV Battery Pack
•The HV battery assembly is enclosed in a metal case and is rigidly mounted
to the cross member in the cargo area behind the rear seat. The metal case
is isolated from high voltage and concealed by a carpeted panel in the cabin
area.
•The HV battery pack consists of 28 low voltage (7.2 Volt) NiMH battery
modules connected in series to produce approximately 201.6 Volts. Each
NiMH battery module is non-spillable and in a sealed case.
•The electrolyte used in the NiMH battery module is an alkaline mixture of
potassium and sodium hydroxide. The electrolyte is absorbed into the
battery cell plates and will not normally leak, even in a collision.

High Voltage Safety
The HV battery pack powers the high voltage electrical system with DC
electricity. Positive and negative orange colored high voltage power cables are
routed from the battery pack, under the vehicle floor pan, to the
inverter/converter. The inverter/converter contains a circuit that boosts the HV
battery voltage from 201.6 to 650 Volts DC. The inverter/converter creates 3-
phase AC to power the motor. Power cables are routed from the
inverter/converter to each high voltage motor (electric motor, electric generator,
and A/C compressor). The following systems are intended to help keep
occupants in the vehicle and emergency responders safe from high voltage
electricity:
High Voltage Safety System
•A high voltage fuse nprovides short circuit protection in the HV battery
pack.
•Positive and negative high voltage power cables oconnected to the HV
battery pack are controlled by 12 Volt normally open relays p. When the
vehicle is shut off, the relays stop electrical flow from leaving the HV
battery pack.
WARNING:
The high voltage system may remain powered for up to 10 minutes after
the vehicle is shut off or disabled. To prevent serious injury or death
from severe burns or electric shock, avoid touching, cutting, or
breaching any orange high voltage power cable or high voltage
component.
•Both positive and negative power cables oare insulated from the metal
body. High voltage electricity flows through these cables and not through
the metal vehicle body. The metal vehicle body is safe to touch because it
is insulated from high voltage components.
•A ground fault monitor qcontinuously monitors for high voltage leakage
to the metal chassis while the vehicle is running. If a malfunction is
detected, the hybrid vehicle computer qwill illuminate the master warning
light in the instrument cluster and indicate “Check Hybrid System” on
the multi-information display.
