Accessory Power Outlets With the accessory power outlets, you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. Your vehicle has three accessory power outlets. The first outlet is located to the right of the cigarette lighter on the instrument panel. The second outlet is located on the rear of the center console, and the third one is located in the rear of the vehicle near the liftgate. Remove the cover from the outlet to use the outlet. Be sure to put the cover back on when not using the accessory power outlet. Certain electrical accessories may not be compatible with the accessory power outlet and could result in blown vehicle or adaptor fuses. If you experience a problem, see your dealer for additional information on the accessory power outlets. 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
