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 liquid s to enter the power outlet, 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 120V AC appliance that requires more than the maximum
capacity of the power outlet. If a 120V AC appliance that consumes more
than the maximum capacity is used, the protection circuit will cut the power
supply.
■ Appliances that may not ope rate properly (120V AC)
The following 120V 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 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 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.

■
Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
■ Precautions when the battery is di scharged (vehicles with a smart key
system)
● In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless remote con-
trol or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a
malfunction.
● The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was discharged. Before disconnecting the bat-
tery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
before the battery discharged, be especially careful when reconnecting
the battery.
