■
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there
is improper tire inflation pressure in the tires, the driving range
when in EV mode will become shorter, and fuel consumption
when in HV mode will increase.
Also, as snow tires can cause lar ge amounts of friction, their use
on dry roads can lead to increas ed fuel and electricity consump-
tion.
■ Luggage
Carrying heavy luggage can require excessive energy. Avoid
leaving unnecessary lu ggage in the vehicle.
Also, equipping a large roof rack can cause excessive energy
consumption in the same way as carrying heavy luggage.
■ Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

84 1-2. Charging
PRIUS PHV_OM_OM47818U_(U)
Confirm that the charging indi-
cator is illuminated. (When the
charging timer function is in
use, the light will turn off sev-
eral seconds after illuminat-
ing.)
Charging will not start if the
charging indicator does not illu-
minate when the charging con-
nector is inserted. (P. 9 9 )
The amount of time until charg-
ing is completed can be
checked on the energy monitor
by turning the “POWER” switch
to ON mode. ( P. 89)
The error warning indicator of
the CCID (Charging Circuit
Interrupting Device) has illumi-
nated during charging:
P. 102
The charging indicator will turn
off when charging is com-
pleted.

Canceling the charging timer function
If the charging timer switch is
pressed while the charging timer
indicator is illuminated or flash-
ing, the charging timer function
will be canceled. Charging will
commence immediately if the
charging cable is connected to
the vehicle.
The charging timer indicator will
turn off if the charging timer func-
tion is canceled.
Displays shown on the multi-information display
Each type of information related to charging is displayed on the multi-
information display.
■ Time until charging is complete
If the “POWER” switch is turned
to ON mode during charging, the
current charging status and the
amount of time needed until
charging is complete will be dis-
played on the energy monitor.
After confirming, switch the
“POWER” switch to OFF and turn
off the display. The “POWER”
switch will turn off automatically
after several tens of seconds.

■Charging messages
The first time the “POWER”
switch is turned to ON mode
after charging is completed, a
message detailing the results of
the charging will be displayed.
Also, if an operation which can-
not be carried out is attempted
during charging, a warning mes-
sage will be displayed.
( P. 562)
Comply with the instructions in
the message and carry out any
necessary operations.
The message may not be dis-
played if the Remote Air Condi-
tioning System ( P. 371) has
been used.
■ Amount of time until charging is complete
Charging fully from an EV driving range of 0 mile (0 km) ( P. 58) will take
approximately 2.5 hours (AC120 V).
The amount of time until charging is complete will change in accordance with
the amount of charge remaining in the hybrid battery (traction battery), the
outside temperature, etc.
■ During charging
● The surface of the CCID (Charging Circuit Interrupting Device) may
become hot, but this does not indicate a malfunction.
● Depending on radio wave conditions, interference may be heard on the
radio.

■Charging timer function (finish time setting mode)
● The finish time setting mode should only be used as a reference for the
time at which charging will finish.
Charging may not complete at the finish time depending on the effects of
the electricity supply, temperature etc. In this event, charging will continue
until completed.
● If the function detects that charging cannot be finished on time, charging
will start immediately, and will continue until fully charged.
■ Charging indicator
● The charging indicator illuminates if the Remote Air Conditioning System
(P. 371) is used during charging or while the charging cable is con-
nected.
● If a system malfunction occurs during charging or during Remote Air
Conditioning System use, the indicator will flash for approximately 10
seconds and then turn off.
■ When the outside temperature is low or high
The level shown on the remaining charge display ( P. 60) may drop slightly
when the “POWER” switch is turned to ON mode, even if charging has been
completed and the hybrid battery (traction battery) is fully charged. However,
this does not indicate a malfunction.
■ Using a DC Charger
DC Chargers cannot be used with this vehicle.

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-
lights or emergency flashers switch is on.
● There is a power outage during charging.
● There is an interruption in the electrical supply.
● There is a drop in the voltage of your panel’s AC supply.
● The charge in the 12-volt battery is low, for example due to the vehicle
being left unused for a long period of time.
■ Capacity reduction of the hybrid battery (traction battery)
The charge 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. By observing the following precautions, battery charge
decline can be suppressed.
● Avoid parking the vehicle in areas with a high temperature under direct
sunlight when the hybrid battery (traction battery) is fully charged.
● Do not accelerate or decelerate frequently and suddenly when driving in
EV mode.
● Avoid frequent driving near the top speed for EV driving. ( P. 40)
● 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.
Also, if the hybrid battery (traction battery) capacity reduces, the EV driving
range decreases. However, vehicle performance does not significantly
become worse.

PRIUS PHV_OM_OM47818U_(U)
■Note for the entry function
● Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel, luggage cover, floor, or in the door pockets or glove box when the hybrid system is started or
“POWER” switch modes are changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave
reception conditions, it may be detected by the antenna outside the cabin
and the door will become lockable from the outside, possibly trapping the
electronic key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
● Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.
● The doors may unlock if a large amount of water splashes on the door
handle, such as in the rain or in a car wash when the electronic key is
within the effective range. (The door will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the entry function. (Use the wireless remote control to
unlock the doors.)
