NOTICE
■To avoid damaging the power outlet and the plug
● Close the power outlet lid when not in use.
● Do not allow foreign objects or liquids to enter the power outl et, as this
may cause a short circuit.
● Do not use plug adaptors to connect too many plugs to the power outlet.
● After removing a plug, gently close the power outlet lid.
■ To prevent the fuse from being blown
Do not use a 120 V AC appliance that requires more than the maximum
capacity of the power outlet. If a 120 V AC appliance that cons umes more
than the maximum capacity 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 con-
sumption is under maximum capacity.
● 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
Turn off all the vehicle's electronic equipment and accessories , such as the
headlights and air conditioning, when electrical appliances tha t 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 t rim, seats and
deck.
● Do not use any electrical appliances that are easily affected b y vibration or
heat inside the vehicle. Vibration while driving, or the heat o f the sun while
parking, may result in damage to those electrical appliances.
