Interior equipment Accessory power outlet In the luggage compartment (if equipped) Do not attempt to use a cigarette lighter in the accessory power outlet. Do not place any foreign objects, especially metal ones such as coins or aluminum foil, into the accessory power outlet. That could cause a short circuit. Always put the cap on the accessory power outlet when it is not in use. Use only electrical appliances which are designed for 12V DC and which consume less than 120W. Overloading the accessory power outlet 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 accessory power outlet, this can result in a poor contact or cause the plug to get stuck. Only use plugs that fit properly. Use of an electric appliance in the accessory power outlet for a long period of time while the engine is not running can cause battery discharge. UB7008EA Electrical power (12V DC) from the battery is on tap at the outlet when the ignition switch is either in the "ACC" or "ON" position. You can use an in-car use electrical appliance by connecting it to the outlet. NOTE The trim cover has a notch through which the connected electrical appliance's cord can be passed. - CONTINUED - 6-19
