WARNING
■When charging
Observe the following precautions.
Failure to do so may cause an unexpected accident, resulting in death or\
serious injury.
● Connect to a power source suitable for charging. ( →P. 122)
● Check that the charging inlet, charging cable, plug and outlet are free of
foreign matter.
● Only use outlets where the plug can be securely inserted.
● Do not charge if the charging cable is coiled or bundled.
● Wrapping 120 V charging cable while in-use is not recommended because
cable may overheat. Failure to rewrap charging cable when not in-use
could result in strangulation or tripping hazard.
● Do not wash the vehicle while the charging cable is connected to the vehi-
cle and when the charging lid is open.
● Do not touch the terminals of the charging connector and charging inlet
with a sharp metal objects (needles etc.) or hands, or short them with for-
eign objects.
● When charging outdoors, make sure to connect to a weatherproof outlet
for outdoor use.
● Do not insert the plug if the outlet is submerged in water or snow.
● Follow these points when charging while it is raining or snowing.
• Check that no snow, water or ice has accumulated around the charging
connector terminals and the vehicle charging inlet. Tap snow, water or
ice gently from connector prior to inserting charging connector into the
vehicle’s charging inlet.
• Do not connect the plug if your hands are wet. Also, do not get the plug or outlet wet.
● Do not charge the vehicle during a lightning storm.
● Do not let the wheels on the charging cable, plug, charging connector and
CCID (Charging Circuit Interrupting Device).
● Firmly insert the plug into the outlet.
● Do not use an extension cord and converting adaptor.

■Timer settings
A maximum of 15 charge schedules can be registered.
■ To make sure that the charging timer function operates correctly
Check the following items.
●Adjust the clock to the correct time ( →P. 185)
● Check that the power switch is turned off
● After registering the charge schedule, connect the charging cable
The charging start time is determined based on the charge schedule at the
time that the charging cable was connected.
● After connecting the charging cable, check that the charging indicator
flashes ( →P. 106)
● Do not use an outlet that has a power cut off function (including a timer func-
tion)
Use an outlet that constantly supplies electricity. For outlets where the
power is cut off due to a timer function, etc., charging may not be carried
out according to plan if the power is cut off during the set time.
■ When the charging cable rema ins connected to the vehicle
Even if multiple consecutive charge schedules are registered, the next
charge will not be carried out according to the timer until the charging cable is
removed and reconnected after charging completes. Also, when the hybrid
battery (traction battery) is fully charged, charging according to the timer will
not be carried out.
■ “Climate Prep”
●When the air conditioning-linked setting is turned on, the air conditioning
operates until the set departure time. T herefore, the air conditioning will con-
sume electricity and charging may not complete by the set departure time.
● If the hybrid battery (traction battery) is fully charged, charging will not be
carried out, even if the charge schedule is set. However, if “Climate Prep” is
turned on, the air conditioning will operate only once when it nears the time
set in “Departure”. If this occurs, the air conditioning will consume electricity
and the remaining charge of the hybrid battery (traction battery) when
departing may be decreased.
■ Smartphone-linked op eration (vehicles with 11.6-inch display)
After applying to Entune, it is possible to use the smartphone application to
change charging timer settings.
For details about Entune, refer to http://www.toyota.com/entune/.

WARNING
■Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
● Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.
● When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.
● If anyone is in the vicinity, make sure they are safe and let them know that
the back door is about to open or close.
● Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.
● Do not pull on the back door damper stay to close the back door, and do
not hang on the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to
break, causing an accident.
● If a bicycle carrier or similar heavy object is attached to the back door, it
may suddenly shut again after being opened, causing someone’s hands,
head or neck to be caught and injured. When installing an accessory part
to the back door, using a genuine Toyota part is recommended.
●The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an
incline than on a level surface, so
beware of the back door unexpectedly
opening or closing by itself. Make sure
that the back door is fully open and
secure before using the luggage com-
partment.
● When closing the back door, take extra
care to prevent your fingers etc. from
being caught.
● When closing the back door, make sure
to press it lightly on its outer surface. If
the back door handle is used to fully
close the back door, it may result in
hands or arms being caught.
