Storage Areas Power Outlet Alternating Current The vehicle may have a power outlet that can be used to plug in electrical equipment that uses a maximum limit of 150 watts. The power outlet is located in the rear cargo area on the driver side. The indicator light does not come on when the ignition is in LOCK/OFF or if no equipment is plugged into the outlet. If equipment is connected using more than 150 watts, or a system fault is detected, a protection circuit shuts off the power supply and the indicator light turns off. To reset the circuit, unplug the item and plug it back in or turn the Retained Accessory Power (RAP) off and then back on. The power restarts when equipment using 150 watts or less is plugged into the outlet and a system fault is not detected. The power outlet is not designed for the following electrical equipment and may not work properly if these items are plugged into the power outlet: . Equipment with high initial peak wattage such as: compressor-driven refrigerators and electric power tools. Other equipment requiring an extremely stable power supply such as: microcomputer-controlled electric blankets, touch sensor lamps, etc. . An indicator light on the outlet turns on to show it is in use. The light comes on when the ignition is in ON/RUN and equipment requiring less than 150 watts is plugged into the outlet, and no system fault is detected.
