Interior equipment Do not hold the lighter pushed in, because it will overheat. ! Using as an accessory power outlet Electrical power (12V DC) from the battery is on tap at the socket when the ignition switch is either in the "ACC" or "ON" position. If you use the socket as an accessory power outlet, take the following precautions. When the socket is not in use, always put the cap on the socket to prevent any foreign object from entering it. " Use of an electric appliance in the socket for a long period of time while the engine is not running can cause battery discharge. " Before driving your vehicle, make sure that the plug and the cord on your electrical appliance will not interfere with your shifting gears and operating the accelerator and brake pedals. If they do, do not use the electrical appliance while driving. If the socket has been used for electrical appliances, damage may have been done to the internal mechanism that causes a cigarette lighter to "pop out" after its element has been heated. For that reason, a cigarette lighter, even if it is a genuine part, should not be used in the socket. If you want to use the socket for a cigarette lighter again, or to protect your purchaser before you sell your car, have your SUBARU dealer replace the socket with a new one. " Use only in-car use electrical appliances which are designed for 12V DC and which consume less than 120W. Overloading the socket can cause a short circuit. Do not use double adapters or more than one electrical appliance. " If the plug on your electric appliance is either too loose or too tight for the socket, this can result in a poor contact or cause the plug to get stuck. Only use plugs that fit properly. - CONTINUED - 6-13
