Certain electrical accessories may not be compatible with the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer for additional information on accessory power outlets. Notice: Adding some electrical equipment to your vehicle can damageit 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. Ashtrays and Cigarette Lighter Your vehicle may be equipped with an ashtray and cigarette lighter. Pull the front ashtray door down to open it. Notice: Don't put papers or other flammable items into your ashtrays. Hot cigarettes or other smoking materials could ignitethem, causing a damaging fire. To remove the front ashtray, pull the bin upward. 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. 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: 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. 3-1 8
