NOTICE
To avoid damaging the power outlet and the plug
Close the power outlet lid when not in use.
Foreign objects or liquids that enter the power outlet may cause a short
circuit.
Do not use plug adaptors to connect too many plugs to the power outlet.
After inserting a plug, gently close the power outlet lid.
To prevent the fuse from being blown
12 V
Do not use an accessory that uses more than 12 V 10 A.
120 V AC
Do not use a 120 V AC appliance that requires more than 100 W.
If a 120 V AC appliance that consumes more than 100 W is used, the pro-
tection circuit will cut the power supply.
Appliances that may not operate properly (120 V AC)
The following 120 V AC appliances may not operate even if their power con-
sumption 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
To prevent the battery from being discharged
Turn off all the vehicle’s electronic equipment and accessories, such as the
headlights and air conditioning, when electrical appliances that consume in
excess of 100 W are used continuously for long periods of time.
To prevent any damage caused by heat
Do not use any electrical appliances that give off intense heat such as
toasters, in any locations including the internal or external trim, seats and
deck.
Do not use any electrical appliances, which are easily affected by vibration
or heat, inside the vehicle.
Vibration while driving, or the heat of the sun while parking, may result in
damage to those electrical appliances.

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. 539)
If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.

CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing 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 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 fuse or the fuse box.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Toy-
ota dealer as soon as possible.
