For safety, inspect the charging cable on a routine basis.
Inspecting and maintaining the charging cable
WARNING
■Routine inspection
Check the following points regularly.
Failure to do so may cause an unexpected accident, resulting in death or
serious injury.
● The charging cable, plug, charging connector, CCID (Charging Circuit
Interrupting Device) etc. have not been damaged
● The socket has not been damaged
● The plug can be securely inserted into the socket
● The plug does not get extremely hot during use
● The tip of the plug has not been deformed
● The plug is not dirtied by dust etc.
Remove the plug from the socket before inspecting it. If any abnormalities
are found in the charging cable as a result of the inspection, immediately
stop use and consult any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
■ Maintaining the charging cable
When the charging cable is dirty, first remove the dirt with a hard, wringed
cloth, and then wipe the cable with a dry cloth.
However, never wash it with water. If the charging cable is washed with
water, fire or electric shock may oc cur during charging, possibly resulting in
death or serious injury.
■ When not using the charging cable for a long time
Remove the plug from the socket. Dust could accumulate on the plug or in
the socket, possibly causing overheating which could lead to a fire.
Also, keep the cable in a place free from moisture.

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.

tion or fire, possibly leading to death or serious injury.
■ Charging equipment
There is charging equipment under the r ear seats. Make sure to observe
the following precautions regarding the charging equipment. Failure to
observe these precautions may result in death or serious injury such as
