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 may have accessory power outlets. The first two outlets are located below the cigarette lighter and the rear wiper switch on the instrument panel. The third outlet is located on the rear of the center console. 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. 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. Ashtrays and Cigarette Lighter The front ashtray is removable and fits into the front cupholder. Notice: Don't put papers or other flammable items into your ashtrays. Hot cigarettes or other smoking materials could ignite them, causing a damaging fire. TO remove the front ashtray, pull the covered bin out of the cupholder. To use the lighter, press it in all the way, and let go. When it's ready, it will pop back out by itself. 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 amperage rating. Notices Don't hold a cigarette lighter in with your hand while it is heating. If you do, it won't be able to back away from the heating element when it's ready. That can make it overheat, damaging the lighter and the heating element. 3-19
