■Solar charging system
●In the following cases, charging the traction battery via the solar charging system is not performed.
• The power switch is not off • The traction battery heater is operat-ing ( P.114)
• The Remote Air Conditioning System is operating• The traction battery is fully charged
• The traction battery is completely dis- charged
●In the following cases, the solar charging system stops solar power generation and power supply to the
traction battery and auxiliary systems. • The hood is opened• AC or DC charging has started
• When using “My Room Mode” • The temperature preservation function

of the solar charging system operates
• There is a malfunction in the solar charging system
●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
droppings 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 traction battery is fully charged, charging the battery via the solar charging system is not per-
formed. When it is not necessary 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.
●Applying a glass coating to the solar roof may change the refractive index of light and reduce the amount of
power generated.
●Small dots, lines, and stains may be
visible inside the solar roof, however there is no problem with the power generation function or safety.
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 imme-
diately request repairs from any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
