Instruments and Controls To use an outlet, remove the protective cap. When not in use, always cover the outlet with the protective cap. The accessory power outlet is operational at all times. Notice: If electrical devices are left plugged into a power outlet, the battery may drain causing the vehicle not to start or damage to the battery. This would not be covered by the vehicle warranty. Always unplug all electrical devices when turning off the vehicle. 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/retailer for additional information on accessory power outlets. Notice: Adding any electrical equipment to the vehicle can damage it or keep other components from working as they should. The repairs would not be covered by the vehicle warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. Notice: Improper use of the power outlet can cause damage not covered by the vehicle warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. 4-13 Cigarette Lighter The vehicle may have a cigarette lighter. To use the lighter, push it in all the way and let go. When it is ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating does not let the lighter back away from the heating element when it is hot. Damage from overheating can occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating.
