DUAL FUEL TANK SELECTOR CONTROL (IF EQUIPPED)
If your vehicle is equipped with dual fuel tanks, you will have a selector
control, located to the right of the steering wheel, which allows you to
draw fuel from either tank. Your fuel gauge will display the amount of
fuel in the currently selected tank.
Fuel level indication is delayed for several minutes when the tank
selector switch is actuated. Fuel level indication can be obtained
immediately by turning off and restarting the engine.
MANUAL TRANSMISSION SHIFT SPEEDS
Do not overspeed the engine when going downhill or steep grades. If
equipped, use the tachometer and do not allow engine speed to exceed
the redline area. Operating the engine beyond the recommended speeds
can cause severe engine damage.
If your vehicle is an F-Series equipped with a manual
transmission, your vehicle has an electronic operating strategy
which protects the engine system when the engine is operating
with high coolant temperatures; fueling to the engine will be
modified to prevent damage to the engine. Some power loss may
be experienced if the vehicle is overloaded.

For high altitude operation reduce GCWR by 2% per 300 meters (1 000
ft) elevation.
To determine the maximum trailer weight designed for your particular
vehicle as equipped, follow the sectionCalculating the load your
vehicle can tow/carryearlier in this chapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Distribute the load so that only 10 to 15% of the total is on the tongue.
Tie down the load so that it does not shift and change the weight on the
hitch.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight could result in engine damage, transmission/axle damage,
structural damage, loss of control and personal injury.
