◆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 distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the weather,
the outside temperature, usage conditions of electrical components
and the number of occupants.
The distance that can be driven in EV mode can be extended if the fol-
lowing is performed:
●Maintain a safe distance from the vehicle in front and avoid unnec-
essary acceleration and deceleration
●Accelerate and decelerate the vehicle as smoothly as possible
●Drive at moderate speeds as much as possible and maintain a con-
stant speed
●
Set the air conditioning to a moderate temperature and turn the “A/C”
switch ( ) off when it is not needed
●Use tires of the specified size and maintain the specified tire pres-
sure
●Use the EV/HV mode selection switch to drive in HV mode when
driving on a highway
Electricity consumption will increase substantially when driving on a
highway in EV mode.
●Do not add unnecessary weight to the vehicle
The following indicate that charging has been carried out properly.
●The charging indicator turns off
●The Hybrid battery (traction battery) status indicators illuminate for
approximately 15 seconds. (P. 123)
●“Charging Complete” is displayed on the multi-information display
when starting off (P. 159)
Regardless of the type of power source or whether the charging
schedule function is used, charging is completed if the above can be
confirmed.

Charging methods
◆Charging from an external power source (P. 165)
This is a charging method used when charging from an AC socket
(220 V-240 V) with the charging cable equipped to the vehicle or
charging at a public charging station.
The charging start time (or departure time) and day can be set to carry
out charging using the charging schedule at the desired date and time.
(P. 176)
◆Using the hybrid battery (traction battery) charge mode
(P. 9 9 )
The plug-in hybrid system can be switched to hybrid battery (trac-
tion battery) charge mode to charge the hybrid battery (traction bat-
tery) using electricity generated by gasoline engine operation.
The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
◆Solar charging system (if equipped) (P. 188)
In certain conditions, when the vehicle is parked, the hybrid battery
(traction battery) can be charged by using electricity generated by
the solar panel equipped to the roof of the vehicle.
The maximum charge amount of the solar charging system is approxi-
mately 90% of the fully charged capacity for the charging from an exter-
nal power source. (This does not mean the battery can be fully charged
in one day.)
The following methods can be used to charge the hybrid battery
(traction battery).

1542-2. Charging
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
■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.

■Capacity reduction of the hybrid battery (traction battery)
The capacity of the hybrid battery (traction battery) will decline gradually
when the hybrid battery (traction battery) is in use. The rate at which it
declines will differ in accordance with environmental conditions and the way
in which the vehicle is used. Observing the following can help suppress bat-
tery capacity decline.
●Avoid parking the vehicle in areas with a high temperature under direct sun-
light when the hybrid battery (traction battery) is fully charged.
●Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.
●Avoid frequent driving near the top speed for EV driving. (P. 1 0 4 )
●Leave a low level of charge in the hybrid battery (traction battery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the power
switch off.
●Use the charging schedule function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting off.
(P. 176)
Also, if the hybrid battery (traction battery) capacity reduces, the distance that
can be driven in EV mode decreases. However, vehicle performance does
not significantly become worse.
■When the remaining charge of the hybrid battery (traction battery) is low
after charging
In the following situations, the remaining charge of the hybrid battery (traction
battery) after charging completes may be less than normal in order to protect
the system (the EV driving range after the battery is fully charged may be
shorter).
*
●Charging is carried out when the outside temperature is low or high
●Charging is carried out immediately after high-load driving or in extreme
heat
When none of the above situations apply and there is a drastic drop in the
remaining charge of the hybrid battery (traction battery) after charging com-
pletes, have the vehicle inspected by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remaining charge rapidly
decreases faster than normal.
■When the charging amount sent to the hybrid battery (traction battery)
decreases
When the amount of power supplied by the charger is low or operation of the
“Traction Battery Heater”, etc., reduces the charging power sent to the hybrid
battery (traction battery), the charging amount sent to the hybrid battery (trac-
tion battery) may decrease.
