For safety and security
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem. DC and AC high voltage is very dangerous and can cause severe
burns and electric shock that may result in death or serious injury.
●Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
●The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the warning labels attached to the vehicle.
●Do not touch the service plug located
under the right side of the rear seat. The
service plug is used only when the vehi-
cle is serviced and is subject to high
voltage.

For safety and security
WARNING
■Hybrid battery (traction battery)
●AXVH70 model
*: Your vehicle contains a sealed lithium-ion battery.
●Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-
ardous to the environment or someone may touch a high voltage part,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident
is extremely high because the person receiving the vehicle may not be
aware of these dangers.
●If your vehicle is disposed of without the hybrid battery having been
removed, there is a danger of serious electric shock if high voltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by your
Toyota dealer or a qualified service shop. If the hybrid battery is not dis-
posed of properly, it may cause electric shock that can result in death or
serious injury.
*: The model code is indicated on the Certification Label. (P. 545)

Operation of each component
WARNING
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in seri-
ous injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before
opening it. Failure to do so may cause the trunk lid to suddenly shut again
after it is opened.
●When opening or closing the trunk lid, 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 trunk is about to open or close.
●Use caution when opening or closing the trunk lid in windy weather as it
may move abruptly in strong wind.
●On an incline it is more difficult to open or close the trunk lid than on a level
surface, so beware of the trunk lid unexpectedly opening or closing by
itself. Make sure that the trunk lid is fully open and secure before using the
trunk.
●Do not attach any accessories other than genuine Toyota parts to the trunk
lid. Such additional weight on the trunk lid may cause the lid to suddenly
shut again after it is opened.
●When opening the trunk lid, take care
so that it does not hit anyone in the face
or any other part of the body.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
●When closing the trunk lid, make sure to
press it lightly on its outer surface.

1683-2. Opening, closing and locking the doors
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to
the rear bumper center when the trunk is opened.
• The electronic key is on the instrument panel, rear package tray or floor,
or in the door pockets or glove box when the hybrid system is started or
power switch modes are changed.
●Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
●Even if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.
●The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash, when the electronic key is
within the effective range. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
●If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
*
●If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
<00490052004f004f0052005a004c0051004a00030046005200550055004800460057004c00520051000300530055005200460048004700580055004800560003005700520003005a00440056004b00030057004b0048000300590048004b004c0046004f00

• Place the electronic key in a location 6 ft. (2 m) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart key
system. (P. 166)
●If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.
