Plug-in hybrid system
PRIUS PHV_OM_OM47C99E_(EE)
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 battery
When the solar roof is not exposed to sunlight or the vehicle is not driven for a
long period of time, the solar battery may be discharged, negatively affecting
the system.
If storing the vehicle inside of a garage away from the sun or if the vehicle will
not be used for a long period of time, use one of the following methods to
charge the solar battery at least once every 2 to 3 months.
● Start the hybrid system and keep the READY indicator turned on for approx-
imately 60 minutes or more
● Park the vehicle outside of the garage so that the solar roof is in direct sun-
light for approximately 2 hours or more
(In this case, it is not necessary to start the hybrid system)
NOTICE
■ To protect the solar charging system from damage
● Make sure to observe the following precautions.
• Do not modify the solar roof
• Do not condense sunlight onto the solar roof
• Do not place anything on top of the solar roof
• Do not subject the solar roof to strong impacts or apply force with sharp
objects from the inside roof of the vehicle.
● If the solar roof is damaged, do not touch the damaged area and immedi-
ately request repairs from any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.

If “Charging Stopped High Energy Use See Owner’s Manual” is shown
Power is being consumed by electri-
cal components of vehicle
Check the following items, and then
carry out charging again.
• If the headlights and audio are
turned on, turn them off.
• Turn the power switch off.
If charging cannot be carried out,
even after performing the above, the
auxiliary battery may not be suffi-
ciently charged. Operate the hybrid
system for approximately 15 min-
utes or more to charge the auxiliary
battery.
If “Charging System Malfunction See Owner’s Manual” is shown
Malfunction occurred in charging
system
Have the vehicle inspected by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
