Accessory Power Outlet(s) Accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular telephone or CB radio. There are two under the climate controls, one inside the center floor console, one on the rear of the center floor console and one accessory power outlet in the rear cargo area on the passenger side. To use an accessory power outlet, remove the protective cap. When not in use, always cover the accessory power outlet with the protective cap. The accessory power outlets are powered, even with the ignition off. Continuing to use accessory power outlets while the ignition is in LOCK/OFF may cause the vehicle's battery to run down. Notice: If electrical devices are left plugged into a power outlet, the battery may drain causing your vehicle not to start or damage to the battery. This would not be covered by the warranty. Always unplug all electrical devices when turning off your vehicle. Certain accessory plugs may not be compatible to the accessory power outlet and could result in blown adapter or vehicle fuses. If you experience a problem, see your dealer/retailer for additional information on the accessory power plugs. Notice: Adding any electrical equipment to your vehicle may damage it or keep other components from working as they should. The repairs would not be covered by your warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. Do not use equipment exceeding the maximum amperage rating of 20 amperes. Notice: Improper use of the power outlet can cause damage not covered by your 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. 3-22
