Accessory Power Outlets With accessory power outlets you can plug in auxiliary electrical equipment such as a cellular telephone or other devices designed to operate with vehicle electrical systems. Your vehicle is equipped with five accessory power outlets. The two front outlets are located under the OnStar buttons on the instrument panel. The two middle outlets are located on the back of the center console. There is also one accessory power outlet located in the rear of the vehicle near the liftgate. Flip the cover open to use the outlet. Close the cover when the outlet is not in use. Certain power accessory plugs may not be compatible to the accessory power outlets and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer for additional information on the accessory power plugs. NOTICE: Adding some electrical equipment to your vehicle can damage it or keep other things from working as they should. This wouldn't be covered by your warranty. Check with your dealer before adding electrical equipment, and never use anything that exceeds the fuse rating. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. NOTICE: Power outlets are designed for accessory plugs only. Do not hang any type of accessory or accessory bracket from the plug. Improper use of the power outlet can cause damage not covered by your warranty. 2-65
