Continuous Mode

WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

This mode can be operated only when the vehicle is not moving and the transmission is in PARK (P) and will provide up to 2,400 watts of 120-volt AC power to the outlets. Continuous mode can be operated with the key removed from the ignition. The engine will run continuously in this mode to supply electrical power to the APO system.

To activate the continuous mode, do the following:

Place the transmission in PARK (P) with the ignition in RUN and the engine running. See "Ignition Positions" in your owner manual Index.
Turn the ignition key to LOCK while the light is flashing. The light will flash for up to 30 seconds. When the ignition key has been turned to LOCK, the light next to the APO switch will stop flashing and remain on. The engine will continue to run.
Connect any 120-volt AC electrical/electronic device(s) to the outlets. If you must use extension cords, be sure to use only UL® approved extension cords.

You can remove the key from the ignition at this point.

If the system stops supplying 120-volt AC power unexpectedly and the light next to the APO button starts flashing, the system has detected an overload or ground fault condition. To reset the system see "Resetting the Short Circuit, Overload or Ground Fault Detection (GDF) Circuit" later in this section.

The APO system will operate in the continuous mode with the engine running until one of the following occurs:

You press the APO button. The light in the APO button will turn off and the engine will turn off.
If the fuel level gets low.
A FUEL LEVEL LOW message will appear in the DIC and the horn will sound intermittently for five seconds every minute for five minutes.

If the vehicle is left unattended for the full five minute warning, the engine and APO system will shut down, unless the APO button is pressed during the five minute warning period.
An overload or ground fault condition is detected and not reset in five minutes.
Vehicle security is violated.
Engine oil pressure becomes too low.
Engine coolant temperature becomes too hot.
The ignition key is moved out of LOCK.
This may display a low oil warning message and chimes which is a normal condition when the APO button was not used to shut off the continuous mode.
The hybrid power system becomes too hot.
