■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.

■ 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 luggage is loaded on the roof

The error warning indicator on the CCID (Charging Circuit Interrupting
Device) flashes.
Electrical leakage detection function
or self- diagnostic function operates
and power is cut off
When the voltage is insufficient, the
error warning indicator may flash
when there is noise interference.
Perform a reset and connect to a
proper power source. (P. 129)
If charging does not start, immedi-
ately stop charging and contact any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.

there is no time to finish charging by
the set scheduled departure time, it
starts charging immediately. Check
the charge schedules.
Charging cable was removed and
reinserted while charging indicator
was flashing
If the charging cable is removed and
reinserted while the charging indica-
tor is flashing, the charging timer is
canceled (P. 163). Temporarily
remove the charging cable, and then
reconnect it.
The Remote Air Conditioning Sys-
tem was operated
When the Remote Air Conditioning
System is operated, the system will
start charging immediately, even if
the charge schedule is registered.

When the charging mode is set to
“Departure”, “Traction Battery
Heater” may operate before
charging starts. Check the status of
the charging indicator. (P. 125)
Charging ends earlier than time set in “Departure”
Charging end time does not match

Charging is not complete, even though it is time set in “Departure”
“Climate Prep” is set to “On”
(vehicles with “Climate Prep” func-
tion)
When “Climate Prep” is set to “On”,
the air conditioning operates until
the set departure time. Therefore,
charging may not complete by the
set time due to charging conditions.
To have the hybrid battery (traction
battery) fully charged, allow
charging to continue.
Charging end time does not match
estimated end time due to condition
of power source or outside tempera-
tureIf sudden changes in temperature or
changes in the condition of the
power source occur while charging,

hybrid battery (traction battery) as it
continued to remain hot for a certain
period of time.Allow the hybrid battery (traction
battery) to cool down and perform
charging again if the charging
amount has not reached the desired
amount.
