Do not insert any other object in the power outlet as this will damage the outlet and blow the fuse. 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. The auxiliary power point is located on the instrument panel. Do not use the power point for operating the cigarette lighter element (if equipped). To prevent the fuse from being blown, do not use the power point(s) over the vehicle capacity of 12 VDC/180W. If the power point or cigar lighter socket is not working, a fuse may have blown. Refer to Fuses and relays in the Roadside Emergencies chapter for information on checking and replacing fuses. To have full capacity usage of your power point, the engine is required to be running to avoid unintentional discharge of the battery. To prevent the battery from being discharged: • do not use the power point longer than necessary when the engine is not running, • do not leave battery chargers, video game adapters, computers and other devices plugged in overnight or when the vehicle is parked for extended periods. 70 2009 F-150 (f12) Owners Guide (own2002), 3rd Printing USA (fus)
