Plug-in hybrid system
PRIUS PHV_OM_OM47A89E_(EE)
The plug-in hybrid system operates in the following modes.
The multi-information display can be used to check which mode the plug-in
hybrid system is currently being driven in. (P. 215)
EV mode
When a sufficient amount of electricity is remaining after
charging
*1, EV driving is performed using electricity stored in the
hybrid battery (traction battery).
*2
When in EV mode, the EV drive mode indicator illuminates.
*1: The amount of remaining charge can be checked on the multi-informa-
tion display etc. (P. 227)
*2: Depending on the situation, EV driving may be canceled and both gaso-
line engine and electric motor are used. (P. 98)

902-1. Plug-in hybrid system
PRIUS PHV_OM_OM47A89E_(EE)
EV City mode (P. 9 2 )
When a sufficient amount of electricity for EV driving is remaining in
the hybrid battery (traction battery)
*1, the operation mode can be
switched to EV City mode.
EV City mode limits motor output and minimizes the operation of
the gasoline engine.
*2 Therefore, the vehicle can be driven with
only electric motor (traction motor) in city areas, etc.
When in EV City mode, the EV City mode indicator illuminates.
*1: The amount of remaining charge can be checked on the multi-informa-
tion display etc. (P. 227)
*2: When acceleration is required, fully depress the accelerator pedal to
start the gasoline engine.
HV mode
When in HV mode, the vehicle is driven using both the gasoline
engine and electric motor. (P. 9 6 )
●If electricity needed for EV driving in EV mode is not remaining,
the operation mode will be automatically switched to HV mode.
●The operation mode can be switched to HV mode at any timing
by operating the switch to keep electricity for EV driving etc.
*
(P. 92). Switching to HV mode when driving on a highway or
when driving uphill is recommended in order to conserve battery
power.
When in HV mode, the EV drive mode indicator and EV City mode indi-
cator turn off.
*: The EV driving range may reduce even after switching to HV mode.

When in EV mode
In EV mode, EV driving (driving using only the electric motor)
* is
possible. However, depending on the situation, EV driving may be
canceled and both gasoline engine and electric motor are used
(P. 98). Also, if a little electricity is remaining in the hybrid battery
(traction battery), HV mode is automatically selected. To drive in EV
mode long, observe the followings.
●Avoid sudden acceleration and sudden deceleration, and be sure
to drive smoothly.
If you repeatedly accelerate, the hybrid battery (traction battery)
charge will deplete quickly. Also, EV driving may be canceled by
rapid acceleration or vehicle speed.
●Restrain your speed as much as possible. The distance that can
be driven in EV mode will reduce considerably at high speeds.
*: The EV driving range can be checked using the multi-information dis-
play etc. (P. 210, 226, 233, 250)
■
When in EV City mode
In EV City mode, EV driving (driving using only the electric motor) is
possible.
*1
●Motor output is limited at the same level unless the accelerator
pedal is fully depressed.
When it is necessary to accelerate the vehicle, depress the
accelerator pedal completely or cancel EV City mode as needed.
●In the following situations, EV City mode is automatically can-
celed.
*2
• When driving in EV driving is not possible. (P. 9 8 )
• When Dynamic radar cruise control with full-speed range is
activated.
• When the accelerator pedal is fully depressed.
*1: The EV driving range can be checked using the multi-information dis-
play etc. (P. 210, 226, 233, 250)
*2: Depending on the circumstances, EV City mode may also be canceled
in situations other than those above.
Control when driving in each mode

982-1. Plug-in hybrid system
PRIUS PHV_OM_OM47A89E_(EE)■Refilling fuel
Plug-in hybrid vehicles can be driven using electricity charged from an exter-
nal power source. However, as the gasoline engine is used depending on the
situation even if in EV mode, and the gasoline engine is provided on board as
a power source for driving in HV mode, it is needed to refueling the vehicle.
Check the fuel amount and refill immediately when the fuel level becomes
low. (P. 355)
■Gasoline engine operation in EV mode
Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range (P. 210, 226, 233, 250) is being
displayed on the multi-information display etc., EV driving (driving using only
the electric motor) may be canceled and both gasoline engine and electric
motor are used depending on the situation (EV driving will be returned to
automatically after EV driving becomes possible again).
EV driving may be canceled automatically in the following circumstances:
●When vehicle speed is more than approximately 135 km/h (84 mph).
●When power is needed temporarily, for example when the accelerator pedal
is depressed firmly or when accelerating suddenly.
●When the temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.
●When the temperature of the hybrid system is low.
●When the heater is switched on when the outside temperature is below
about -10C (14F).
●When the windshield defogger switch is pressed. (P. 509)
●When the system determines that the gasoline engine needs to be started.
The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions
*:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the windshield defogger switch is pressed. (P. 509)
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.

Plug-in hybrid system
PRIUS PHV_OM_OM47A89E_(EE)■If the vehicle is not used for a long time
●The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(P. 573)
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) from
external power source or start the hybrid system at least once every 2 or 3
months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after
approximately 10 seconds have passed since the “READY” indicator came
on, the power switch can be turned to off without any further action.)
●When the vehicle is left with the charging cable connected, the electricity
consumption amount of the 12-volt battery increases due to controls, such
as the system checking, operating. When the charging cable is not needed,
immediately remove it from the vehicle.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. For safety, apply the parking
brake and make sure to shift the shift position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction.
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the
hybrid battery (traction battery), behind the rear seats, when the hybrid sys-
tem is started or stopped.
●Sounds from the hybrid system may be heard when the back door is open.
●Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent. (P. 102)
■Maintenance, repair, recycling, and disposal
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.

◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
●Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
◆When braking
Make sure to operate the brakes gently and a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leaving and avoid delays as much as
possible. When driving in a traffic jam, gently release the brake
pedal to allow the vehicle to move forward slightly while avoiding
overuse of the accelerator pedal. Doing so can help control exces-
sive electricity and fuel consumption.
◆Highway driving
●Control and maintain the vehicle at a constant speed. Before
stopping at a toll booth or similar, allow plenty of time to release
the accelerator and gently apply the brakes. A greater amount of
electrical energy can be regenerated when slowing down.
●Electricity consumption will increase significantly when driving at
high speeds in EV mode. If there will be a long distance to the
next external charging point after leaving a freeway, it is recom-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.
