NOTICE
To prevent the fuse from being blown
12 V DC: 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 protection 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 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
To prevent battery discharge
12 V DC: Do not use the power outlet longer than necessary when the engine is not
running.
120 V AC: 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 (120 V AC)
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 that 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.
If any electrical appliances are to be used while driving (120 V AC)
Securely fasten both the appliances and their cables to prevent them from falling or
getting caught in any of the power train components.
If the power outlet is loose when an electrical appliance plug is connected (120 V
AC)
Replace the outlet. Contact your Lexus dealer for any necessary replacements.
If the power outlet gets dirty (120 V AC)
Turn the main switch off and use a soft, clean cloth to wipe it gently. Do not use any
cleansing materials, such as organic solvents, wax, or compound cleaners, as these
may damage the power outlet or cause it to malfunction.

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. 491)
If the replaced fuse blows again, have the vehicle inspected by your Lexus dealer.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION
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 indicated, or use any other object
in place of a fuse.
Always use a genuine Lexus fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
Do not modify the fuses or the fuse boxes.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus dealer,
as soon as possible.
