■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
Do not use a 115V AC appliance that requires more than 100W.
If a 115V AC appliance that consumes more than 100W is used, the protec-
tion circuit will cut the power supply.
■ Appliances that may not operate properly
The following 115V AC appliances may not operate even if their power con-
sumption is under 100W.
●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 elec trical appliances that consume in
excess of 100W 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.
■ If any electrical appliances are to be used while driving
Securely fasten both the appliances and their cables to prevent them from
falling or getting caught any of the power train components.
