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. 141)
• 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.

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 dealer or repairer,
or another duly qualified and
equipped professional.
