1042-1. Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
■After EV mode has switched to HV mode due to low hybrid battery (trac-
tion battery) charge
If the hybrid battery (traction battery) is regenerated by driving continuously
down a long slope, the EV driving range etc. will be displayed on the multi-
information display and EV mode will be automatically switched to.
If EV mode is not switched to even though EV driving range is being dis-
played, EV mode can be switched to by pressing the EV/HV mode selection
switch.
■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. 401)
■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. 225, 241, 248, 265) 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. 577)
●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.

◆Air conditioning
●Turn the “A/C” switch ( ) off when it is not needed. Doing
so can help reduce excessive electricity and fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on the
air conditioning system and reduce electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the seat heaters is effective. (P. 589)
●Using the Remote Air Conditioning System (P. 585) while the
charging cable is connected to the vehicle can reduce electricity
consumption immediately after starting off by operating air condi-
tioning mainly using electricity from an external power source.
●When setting the charging schedule, selecting the start time set-
ting mode and setting “Climate Prep” to “On” can reduce electric-
ity consumption immediately after starting off by operating air
conditioning before charging is completed. (if equipped)
(P. 176)
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there is
improper tire inflation pressure in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to increased fuel and electricity consumption.

The illumination/flashing pattern
changes to inform the user of the
charging status in the following
ways.
*1: If equipped
*2: Turns off after flashing for a certain period of time.
■Charging indicator
When a system malfunction occurs while charging or using the Remote Air
Conditioning System, the charging indicator rapidly flashes for a certain
period of time, and then turns off.
If this occurs, the next time the hybrid system is started, a message is dis-
played on the multi-information display. When a message is displayed, follow
the instructions displayed on the screen.

WARNING
■Power sources precautions
Observe the following precautions.
If you do not follow them, fire, electrical shock and/or damages may occur,
possibly resulting in death or serious injury.
● Connect to an AC 220 V - 240 V socket with a Residual Current Circuit-
Breaker (RCCB) and supplied by a circuit breaker in line with local regula-
tions. Use of an individual circuit provi ded with at least 13A is strongly rec-
ommended.
● Use of a block heater socket which fails to meet the requirements is pro-
hibited for charging.
● Make sure to connect the charging connector and charging inlet directly.
Do not connect a converting adaptor or extension cord between the
charging connector and charging inlet.
● Do not connect the charging cable to a
multi-socket adaptor, multi-plugs, or
conversion plug.
● Connecting the charging cable to an
extension cord is strictly prohibited. The
extension cord may overheat and does
not contain a Residual Current Circuit-
Breaker (RCCB).
The leakage detection function of the
CCID (Charging Circuit Interrupting
Device) may not operate correctly.
● Do not connect to a power strip.

■Charging time may increase
In the following situations, charging time may become longer than normal:
●In very hot or very cold temperatures.
●The vehicle is consuming a lot of electricity, for example, when the head
light switch is on etc.
●There is a power outage during charging.
●There is an interruption in the electrical supply.
●There is a drop in the voltage of external power source.
●The charge in the 12-volt battery is low, for example due to the vehicle being
left unused for a long period of time.
●The maximum charging current is set to 8A through the “Vehicle Settings”
settings. (P. 150)
●When the “Traction Battery Heater” operates.
●When the “Traction Battery Cooler” is operated before charging. (if
equipped) (P. 155)
●When the plug generates heat due to a loose socket connection etc.
■Using a DC Charger
DC Chargers cannot be used with this vehicle.
This vehicle is equipped with several functions that are linked with
charging.
■“Traction Battery Heater”
When the outside temperature is low and the charging cable is con-
nected to the vehicle, this function automatically warms the hybrid
battery (traction battery) until it reaches or exceeds a certain tem-
perature.
●When the charging cable is removed from the vehicle or remains
connected to the vehicle for approximately 3 days, the system
automatically stops.
●When the charging schedule is used (P. 176), this function will
operate according to the charging schedule.
