PRIUS PHV_OM_OM47C99E_(EE)■When the charging cable remains connected to the vehicle
Even if multiple consecutive charge schedules are registered, the next
charge will not be carried out according to the timer until the charging cable is
removed and reconnected after charging completes. Also, when the hybrid
battery (traction battery) is fully charged, charging according to the timer will
not be carried out.
■“Climate Prep” (if equipped)
●When the air conditioning-linked setting is turned on, the air conditioning
operates until the set departure time. Therefore, the air conditioning will con-
sume electricity and charging may not complete by the set departure time.
●If the hybrid battery (traction battery) is fully charged, charging will not be
carried out, even if the charge schedule is set. However, if “Climate Prep” is
turned on, the air conditioning will operate only once when it nears the time
set in “Departure”. If this occurs, the air conditioning will consume electricity
and the remaining charge of the hybrid battery (traction battery) when
departing may be decreased.
■When timer settings are ignored
When the following operations are performed while the charging timer is on
standby, timer charging is temporarily canceled and charging is started imme-
diately.
●When the Remote Air Conditioning System (P. 542) is operated
●When turning “Charge Now” on (P. 179)
●When an operation that temporarily cancel charging using the timer
(P. 163)
■Effects of outside temperature
When the charging mode is set to “Departure”, timer settings may be ignored
due to the outside temperature and charging may start immediately.
■“Traction Battery Cooler” (if equipped) (P. 150)
When charging is carried out using the timer, the hybrid battery (traction bat-
tery) cooling function may operate according to the temperature of the hybrid
battery (traction battery).
●When the charging mode is set to “Start”, cooling starts at the set charging
start time.
●When the charging mode is set to “Departure”, cooling starts approximately
30 minutes before the charging start time. However, if there is no time to fin-
ish charging by the timer setting, the hybrid battery (traction battery) cooling
time may be shortened and “Traction Battery Cooler” may not operate.

Solar charging system
This system generates solar power with the solar panel equipped to
the roof of the vehicle (solar roof).
●The hybrid battery (traction battery) is charged
* while parking.
After the solar power is stored in the solar battery, it is transferred
all at once to the hybrid battery (traction battery) to reduce the sys-
tem electrical consumption and charge the battery efficiently.
●The electrical consumption of the hybrid battery (traction battery) is
reduced during driving.
The electrical consumption of the hybrid battery (traction battery) is
suppressed increasing EV driving distance and fuel economy by
supplementing power consumption for the auxiliary systems using
solar power.
*: The maximum charge amount of the solar charging system is approxi-
mately 90% of the fully charged capacity for the charging from an external
power source.
: If equipped
A system that provides power to the hybrid battery (traction bat-
tery) and auxiliary systems by performing solar charging via the
large solar panel (solar roof) equipped on the vehicle roof.
Even when a parking lot does not have charging equipment and in
the event of a disaster, it is possible to charge
* the hybrid battery
(traction battery) without any special operations as long as sunlight
is available.
*: The charging amount via the solar charging system differs depending on
conditions, such as season and weather. Also, there is a limit on the
amount of charging possible per day. It requires at least approximately 10
days to charge to the maximum possible charging amount via the solar
charging system.

■Solar charging system
●In the following cases, charging the hybrid battery (traction battery) via the
solar charging system is not performed. Solar power generation stops when
the solar battery becomes fully charged.
• Charging via an external power source
• The power switch is not off
• The “Traction Battery Heater” is operating (P. 149)
• The Remote Air Conditioning System is operating
• When the amount of remaining charge in the hybrid battery (traction bat-
tery) is approximately 90% or more of the fully charged capacity for the
charging from an external power source
●In the following cases, the solar charging system stops solar power genera-
tion and power supply to the hybrid battery (traction battery) and auxiliary
systems.
• The temperature preservation function of the solar charging system oper-
ates
• There is a malfunction in the solar charging system
• When the 12-volt battery terminals are disconnected
●The amount of power generated by the solar roof differs according to the
season, climate, weather conditions, vehicle angle and surrounding condi-
tions.
●If even part of the solar roof is in the shade, there may be an extreme drop
in power generation.
●Please adhere to the following in order to allow full performance of the solar
roof.
• Clean the roof on a routine basis (Especially fallen leaves and bird drop-
pings can lead to a substantial decrease in power generation)
• Remove snow from the roof as soon as possible
• Do not attach any seals or stickers to the roof
It is recommended not to install a roof carrier etc. unless it is necessary
●When the hybrid battery (traction battery) is fully charged, charging the bat-
tery via the solar charging system is not performed. When it is not neces-
sary to perform charging from an external power source, charge the vehicle
as much as possible using the solar charging system during the day and
use the external power source only at night. As a result, the solar charging
system can be used effectively.
●When the vehicle is left in the hot weather, the temperature preservation
function of the solar charging system becomes easy to operate due to high
temperature of the vehicle interior. The solar charging system can be used
effectively by using a sunshade or parking the vehicle facing north, etc.
