Power Outlets - Description and Operation: Notes

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.

The Auxiliary Power Outlet (APO) system provides up to 2,400 watts of 120-volt AC power. With these power outlets, you can plug in most auxiliary electrical equipment and devices with a maximum limit of 2,400 watts. If you try to use equipment that requires more than the limit, a 20-amp protection circuit will cut the power supply and a light in the APO switch will flash along with a Driver Information Center (DIC) message that will flash 120V OVERLOAD.

When running APO, do not have the front of the vehicle obstructed. Leave at least five feet (1.5 m) of space between the front of the vehicle and any other object. This will allow airflow through the radiator and help to keep the SGCM cooler.

The power outlets are not designed for equipment with high initial peak starting power of greater than 2,400 watts, such as some air compressors, table saws, etc.
