Solar charging sys-
tem*
A system that provides
power to the hybrid battery
(traction battery) and auxil-
iary 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 bat-
tery) without any special oper-
ations as long as sunlight is
available.

( P.108)
• AC charging has started
• The hybrid battery (traction bat-
tery) is fully charged
• The hybrid battery (traction bat-
tery) is completely discharged
●In the following cases, the solar
charging system stops solar
power generation and power sup-
ply to the hybrid battery (traction
battery) and auxiliary systems.
• The temperature preservation function of the solar charging sys-
tem operates
• There is a malfun ction in the solar
charging system
• When the temperature of the hybrid battery (traction battery) is
approximately 23°F (-5°C) or less
●The amount of power generated
by the solar roof differs according
to the season, climate, weather
conditions, vehicle angle and sur-
rounding conditions.
●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
droppings can lead to a substan-
tial 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 neces-
sary.
