■The protection circuit may be activated to cut the power supply if any of the following
conditions apply (120 V AC):
●Use of electrical appliances exceeding 100 W is attempted.
A sound may be heard when the protection circuit is activated. This is normal and does
not indicate a malfunction.
●The total power usage by all electrical featur es (headlights, air conditioning, etc.) has
exceeded the total vehicle maximum for an extended period of time.
■If the protection circuit is activated and the power supply is cut, conduct the following
procedure (120 V AC):
Park the vehicle in a safe place, and then securely apply the parking brake.
Make sure that the power consumption of th e electric appliance is within the maxi-
mum capacity of the power outlet and the appliance is not broken.

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 applia nce 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.
