Accessories For maximum vehicle performance, keep the following information in mind when adding accessories or equipment to your vehicle: • When adding accessories, equipment, passengers and luggage to your vehicle, do not exceed the total weight capacity of the vehicle or of the front or rear axle (GVWR or GAWR as indicated on the Safety Compliance Certification label). Ask an authorized dealer for specific weight information. • The Federal Communications Commission (FCC) and Canadian Radio Telecommunications Commission (CRTC) regulate the use of mobile communications systems that are equipped with radio transmitters, for example, two-way radios, telephones and theft alarms. Any such equipment installed in your vehicle should comply with Federal Communications Commission (FCC) and Canadian Radio Telecommunications Commission (CRTC) regulations and should be installed only by an authorized dealer. • An authorized dealer needs to install mobile communications systems. Improper installation may harm the operation of your vehicle, particularly if the manufacturer did not design the mobile communication system specifically for automotive use. • If you or an authorized Ford dealer add any non-Ford custom electrical or electronic accessories or components to your vehicle, you may adversely affect battery performance and durability. In addition, you may also adversely affect the performance of other electrical systems in the vehicle. AUXILIARY SWITCHES E163431 The auxiliary switch option package provides four switches, mounted in the center of the instrument panel. These switches will operate only while the ignition is in the on position, whether the engine is running or not. It is recommended, however, that the engine remain running to maintain battery charge when using the auxiliary switches for extended periods of time or higher current draws. Note: When your vehicle is equipped with a diesel engine, use the auxiliary switches only while the engine is running. The glow plugs also drain battery power when the ignition key is in the on position. Using the auxiliary switches, even for limited amounts of time, can cause your battery to drain quickly and prevent your vehicle from restarting. When switched on, the auxiliary switches provide 8 amps, 12 amps or 20 amps of electrical battery power for a variety of personal or commercial uses. The relay box for the auxiliary switches is located on the end of the left side of the instrument panel. See your authorized dealer for service. The relays are coded as shown below: 410 Super Duty (TFA)
