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.

WARNING
■Caution when charging
People with implantable cardiac pacemakers or cardiac resynchronization
therapy-pacemakers should not carry out the charging procedure. Ask
someone else to do it.
● Do not approach the charging equipment and charging cable while
charging.
Charging procedure may affect the operation of such devices.
● Do not remain in the vehicle during charging.
Charging procedure may affect the operation of such devices.
● Do not enter the vehicle even to take something out of the luggage com-
partment.
Charging procedure may affect the operation of such devices.
■ When the charging cable is connected to the vehicle
Do not operate the shift lever.
In the unlikely event that the charging cable has been damaged, the shift
position may change from P to another position and the vehicle could move,
possibly leading to an accident.
NOTICE
■ Precautions when handling charging cable
Make sure to observe the following precautions. Failure to observe these
precautions may result in damage to the charging cable and charging inlet.
● Insert the charging connector straight into the charging inlet.
● After inserting the charging connector, do not apply excessive force to or
twist the connector. Also, do not lean on the connector or hang any objects
from it.
● Do not step on or trip over the charging cable.
● Before removing the charging connector, make sure that it is unlocked.
( P. 158)
● After removing the charging cable, promptly return it to its proper location.
● After removing the charging connector, securely install the charging inlet
cap.

NOTICE
■Charging equipment cooling air intake vents
● Do not block the air intake vents with seat covers or luggage
● If the air intake vents are clogged with dust, clean them with a vacuum
cleaner
● Do not allow water or foreign matter to enter the air intake vents
● Do not spill large amounts of water near the air intake vents
If water is spilled, have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional
and do not charge the hybrid battery (traction battery) before the inspec-
tion.
The grilles under the rear seats are the
cooling air intake vents for the charging
equipment installed under the seats.
Make sure to observe the following pre-
cautions regarding the cooling air intake
vents. Failure to observe these precau-
tions may result in a charging system
malfunction.

How to charge
P. 1 4 8
Prepare the charging cable.
When using the Mode 2
charging cable:
Make sure to hold the body of
the plug and insert it firmly into
the socket.
If you have a remote switch, turn it
on.
Check that the power indicator on
the CCID (Charging Circuit Inter-
rupting Device) is illuminated. (If it
is not illuminated, refer to P. 179)
In order to reduce the load on the
socket and plug, when inserting
the plug, use a string, etc. to hang
the CCID (Charging Circuit Inter-
rupting Device) on a hook or equiv-
alent.
This section explains the procedure for charging the hybrid bat-
tery (traction battery) with the equipped charging cable.
When using a charging station, make sure to check the opera-
tion instructions on the charging station.
When the charge schedule is registered, make sure “Charge Now”
is turned on before charging. ( P. 171)
Confirm the following before charging

When using the Mode 3
charging cable (if equipped):
Remove the cap of the charging
connector that is connected to
the charging equipment, and
then connect the charging con-
nector to the charging equip-
ment.
Follow the instructions displayed on the charging equipment for details
regarding how to connect the charging cable and how to start charging.
Depending on the charging device, it may be necessary to receive authori-
zation to use the device. For details, refer to the information displayed on
the charging device.
Open the charging port lid.
( P. 1 1 4 )
The charging inlet light will illumi-
nate.
