The APO system can be used in two dif-
ferent modes — normal and continuous.
Normal
Mode
Use the nor-
mal mode
while the
vehicle is
being driven.
Activating the Normal Mode
1. Start the engine.
2. Press the APO button once. The

senger’s side. These outlets can operate
most auxiliary electrical equipment and
devices.
Resetting the System
If table saws, certain air compressors
and other equipment are used that
exceed the maximum power limit of
2,400 watts, a 20-amp protection circuit
will safely cut the power supply. A light
next to the APO button, located on the
center of the instrument panel, will flash
and 120V OVERLOAD will be displayed
on the Driver Information Center. If this
occurs, press the APO button to reset
the system.
See your Hybrid Owner Manual Supplement.
Continuous Mode
Use the continuous mode only with the
vehicle in Park. The engine will run con-
tinuously to supply electrical power to
the APO system. The vehicle can be
used as a generator to power critical
appliances when electrical power outlets
are not available.
The engine will be running but the vehi-
cle cannot be driven, and most vehicle
electrical systems, including the climate
control fan, windshield wipers and radio,
will be disabled. The key also can be
removed from the ignition while in the
continuous mode.
Activating the Continuous Mode
1. Place the transmission in Park with
the ignition in Run and the engine
running.
2. Press and hold the APO button for at
least two seconds. The indicator light
will flash and 120V READY will be
displayed on the Driver Information
Center.
3. Turn the ignition key to Lock while the
light is flashing. The light will flash for
30 seconds and then remain on. The
engine will continue to run.
4. Connect an electrical device to
an APO. Use only UL
®
approved
extension cords, if needed.
5. Remove the key from the ignition,
if desired.
Note: Never connect the APO system
outlets directly to a building’s circuitry or
another power supply.
