• The amount of remaining charge in the hybrid battery (traction battery) is
below a certain amount
●When the power switch is turned off, a check screen is displayed on the
multi-information display that indicates whether “Traction Battery Cooler” is
implemented. This check screen can be turned on and off in the “Meter Cus-
tomize” settings on the multi-information display (P. 245). However, when
the check screen is set to “Off”, “Traction Battery Cooler” is no longer oper-
ates.
●“Traction Battery Cooler” uses the power of the hybrid battery (traction bat-
tery) and external power source.
• While “Traction Battery Cooler” is operating, the amount of the remaining
charge of the hybrid battery (traction battery) increases and decreases in
a certain range, and does not increase as in normal charging.
• The operation of “Traction Battery Cooler” is recognized as charging by a
charging equipment. The charging equipment that calculates the fee
according to charging time causes a charging fee.

Charging tips
To enable the use of EV mode, we recommend systematically
charging the vehicle.
Before leaving home
In order to use EV mode, charge the hybrid battery (traction battery) at
home before leaving.
The charging timer function ( P. 163) can be used to set the system to
automatically fully charge the hybrid battery (traction battery) before your
desired departure time. It is also pos sible to set the air conditioning to
make the interior in a comfortable state before your desired departure time.
At your destination
Use a public charging station to charge the hybrid battery (traction battery).
If there are no charging facilities at your destination, the hybrid battery
(traction battery) can be charged using the hybrid battery (traction battery)
charge mode. ( P. 9 1 )*
This section explains methods for using the charging function
for this vehicle and checking information related to charging.

While parking
For vehicles with a solar charging system, solar charging is performed to
charge the hybrid battery (traction battery) when the necessary conditions
such as parking are met. (P. 175)
After returning home
In order to drive the next time, charge the hybrid battery (traction battery).
Settings the charge schedule allows you to charge the hybrid battery (trac-
tion battery) at the desired time such as late at night or early in the morn-
ing. Furthermore, the charging timer can be set to automatically charge the
hybrid battery (traction battery) every day or at the same time on certain
days. (P. 163)
Vehicles with a solar charging system:
When the hybrid battery (traction battery) is fully charged, charging the
battery via the solar charging system is not performed. If you are not plan-
ning on driving the vehicle for a few days, refraining from charging the
vehicle until right before you plan on using it will allow the solar charging
system to be used effectively.
*: When using the hybrid battery (traction battery) charge mode while parked,
make sure that no flammable objects are near the vehicle and the vehicle is
parked in a well-ventilated area. (P. 100)

Things to know before charging
This vehicle has been designed to allow charging from an external
power source using a charging cable for exclusive use with standard
household AC sockets.
However, the vehicle differs greatly from standard household electri-
cal goods in the following ways, and incorrect usage could cause fire
or electric shock, possibly leading to death or serious injury.
●The charging operation is designed to operate at 10A continuously
for the charge duration (up to 3 hours 10 minutes). (P. 140)
●Charging can be conducted outdoors.
To charge properly, follow the procedure after reading the explanation
below. Charging is intended to be carried out by licensed drivers only
who properly understand the charging procedure.
●Charging should not be carried out by children.
●When charging with a charging equipment, follow the procedures
for using each equipment.
●When charging using a public charging facility, check the setting of
the charging timer function.
• When the charge schedule is registered, temporarily turn off the
function or turn “Charge Now” on. (P. 169, 171)
• When the charge schedule is set to ON, charging will not start
even if the charging cable is connected. Also, charging fee may
occur due to connection of the charging cable.
Make sure to read the following precautions before connecting
the charging cable to the vehicle and charging the hybrid battery
(traction battery).

PRIUS PHV_OM_OM47A89E_(EE)■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. 9 8 )
●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 timer function as much as possible in order to fully charge
the hybrid battery (traction battery) immediately before starting off.
(P. 163)
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 dealer or
repairer, or another duly qualified and equipped professional.
*: 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.
