■The power outlets can be used when
12 V: The power switch is in ACCESSORY or ON mode.
120 VAC: The power switch is in ON mode.
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
12 V
Do not use an accessory that uses more than 12 V 10 A.
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

■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. 545)
● 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.
