Operation of each component
When reconnecting the 12-volt battery or changing a fuse while the back
door is open
To enable the power back door to operate properly, initialize the system by
completely closing the back door manually. If the 12-volt battery is recon-
nected or a fuse is changed while the back door is closed, initializing the sys-
tem is not necessary.
Customization
Settings (e.g. power back door opening angle) can be changed.
(Customizable features:
P. 556)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
Before driving
Make sure that the back door is fully closed. If the back door is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the luggage compartment may be thrown out, causing an acci-
dent.
Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could
have heat exhaustion or other injuries.
Do not allow a child to open or close the back door.
Doing so may cause the back door to move unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing back door.
Important points while driving
Never let anyone sit in the luggage compartment. In the event of sudden
braking, sudden swerving or a collision, they are susceptible to death or
serious injury.

NOTICE
To avoid damaging the power outlets
Close the power outlet lids when the power outlets are not in use.
Foreign objects or liquids that enter the power outlets may cause a short cir-
cuit.
To prevent blown fuses
X
12 V
Do not use an accessory that uses more than 12 V 10 A.
X
120 VAC
Do not use a 120 VAC appliance that requires more than 100 W.
If a 120 VAC appliance that consumes more than 100 W is used, the protec-
tion circuit will cut the power supply.
To prevent 12-volt battery discharge
Do not use the power outlet longer than necessary when the hybrid system
is off.
Appliances that may not operate properly (120 VAC)
The following 120 VAC appliances may not operate properly even if their
power consumption is under 100 W:
Appliances with high initial peak wattage
Measuring devices that process precise data
Other appliances that require an extremely stable power supply

Maintenance and care
After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (
P. 434)
If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.
WARNING
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
Do not modify the fuses or fuse boxes.
Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring
near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer as soon as possible.

7-2. Steps to take in an emergency
One of the following may be the cause of the problem:
The electronic key may not be functioning properly. (
P. 514)
There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
There may be a malfunction in the immobilizer system. (
P. 91)
There may be a malfunction in the steering lock system.
The hybrid system may be malfunctioning due to an electrical prob-
lem such as electronic key battery depletion or a blown fuse. How-
ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. (
P. 511)
One of the following may be the cause of the problem:
The 12-volt battery may be discharged. (
P. 516)
The 12-volt battery terminal connections may be loose or corroded.
If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on
the situation. Check the following and perform the appropriate
procedure:
The hybrid system will not start even though the correct starting
procedure is being followed. (
P. 229)
The interior lights and headlights are dim, or the horn does not
sound or sounds at a low volume.

7-2. Steps to take in an emergency
If you have a set of jumper (or booster) cables and a second vehicle
with a 12-volt battery, you can jump start your vehicle by following the
steps below.
Open the hood and fuse box
cover.
Open the exclusive jump start-
ing terminal cover.
If the 12-volt battery is discharged
The following procedures may be used to start the hybrid sys-
tem if the 12-volt battery is discharged.
You can also call your Toyota dealer or a qualified repair shop.

7-2. Steps to take in an emergency
Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
Close the exclusive jump starting terminal cover, and reinstall the
fuse box cover to its original position.
When installing, first hook the fuse box cover onto the two rear tabs.
Once the hybrid system starts, have the vehicle inspected at your
Toyota dealer as soon as possible.
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system is off.
Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
When recharging or replacing the 12-volt battery
In some cases, it may not be possible to unlock the doors using the smart
key system when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
The hybrid system may not start on the first attempt after the 12-volt battery
has recharged but will start normally after the second attempt. This is not a
malfunction.
The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the
12-volt battery was discharged. Before disconnecting the 12-volt battery,
turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.
The power back door must be initialized. (
P. 567)
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
