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 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 120 V AC appliance that requires more than the maximum
capacity of the power outlet. If a 120 V AC appliance that consumes more
than the maximum capacity is used, the protection circuit will cut the power
supply.
■ Appliances that may not op erate 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 by 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.
■ 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 in any of the power train components.
■ If the power outlet is loose when an electrical appliance plug is con-
nected
Replace the outlet. Contact your Toyota dealer for any necessary replace-
ments.
■ If the power outlet gets dirty
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

■ Condensation build-up on the inside of the lens
Toyota lamps are vented to all surrounding environmental conditions and may
experience temporary condensation build-up that is visible from outside of the
lamp. Condensation and fogging does not indicate a malfunction of the lamp
assembly. It is normal for condensation to improve and disappea r after time

Warning messageDetails/Actions

5327-2. Steps to take in an emergency
■Starting the engine when the battery is discharged (vehicles wi th an
automatic transmission)
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 running
at a low speed for an extended period, such as in heavy traffic .
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When recharging or replacing the battery
●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 dis-
charged. Use the wireless remote control 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.
● Vehicles with a smart key system: The engine switch mode is mem orized by
the vehicle. When the battery is reconnected, the system will r eturn to the
mode it was in before the battery was discharged. Before discon necting the
battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
