Driver Controls For further information on the Navigation system/SYNC system, refer to the Navigation System and SYNC supplements. UPFITTER CONTROLS (IF EQUIPPED) Your vehicle may be equipped with the Upfitter option package which will provide four switches, mounted in the center of the instrument panel, labeled AUX 1, AUX 2, AUX 3 and AUX 4. These switches will only operate while the ignition is in the on position, whether the engine is running or not. It is, however, recommended that the engine remain running to maintain battery charge when using the Upfitter switches for extended duration or higher current draws. (This is even more important for vehicles with diesel engines since the glow plugs are also draining battery power when the ignition key is in the on position.) When switched on by the operator they provide 10 amps, 15 amps or 30 amps of electrical battery power for a variety of personal or commercial uses. If your vehicle is equipped with this option, there will also be a relay box located on the driver side end of the instrument panel. See your authorized dealer for service. The relays are coded as shown in RELAY the accompanying illustration. 4 RELAY 3 RELAY 2 RELAY 1 121 2009 F-250/350/450/550 (f23) Owners Guide, 3rd Printing USA (fus)
