2006 FORD SUPER DUTY trailer

Tires
•All trailer tires should be of the same size, and construction.
•Select tires that meet the trailer loading requirements.
•Always check tow vehicle and trailer tire pressure before towing.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
•Do not allow the static water level to rise above the bottom edge of
the rear bumper.
•Do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
•Disconnect the trailer tow electrical connector to prevent blown fuses
caused by water entering into your trailer’s electrical wiring.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
Replace front and rear axle lubricants any time the axles have been
submerged in water. Axle lubricant quantities are not to be checked
unless a leak is suspected.
RECREATIONAL TOWING
This applies to all 4x2 trucks with rear wheel drive capability.
An example of recreational towing is towing your vehicle behind a
motorhome. The following recreational towing guidelines are designed to
ensure that your transmission is not damaged.
•Place the transmission in N (Neutral).
•Maximum speed is 35 mph (56 km/h).
•Maximum distance is 50 miles (80 km).
If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must
be exceeded, you must disconnect the driveshaft. Ford recommends the
driveshaft be removed/installed only by a qualified technician. See your
local authorized dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.

Note:If your vehicle is equipped with a manual transmission, the engine
may be required to run while power accessories operate and the parking
brake is set. It is recommended that wheel chocks be used during this
operation.
If you’re parking your vehicle on a grade or with a trailer, press and hold
the brake pedal down, then set the parking brake. There may be a little
vehicle movement as the parking brake sets to hold the vehicle’s weight.
This is normal and should be no reason for concern. If needed, press and
hold the service brake pedal down, then try reapplying the parking
brake. Chock the wheels if required. If the parking brake cannot hold the
weight of the vehicle, the parking brake may need to be serviced or the
vehicle may be overloaded.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the FULL COLD mark on the dipstick).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
If any steering components are serviced or replaced, install new
fasteners (many are coated with thread adhesive or have prevailing
torque features which may not be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications inWorkshop Manual.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle. The axle may

N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Overdrive) with Tow/Haul OFF
D (Overdrive) with Tow/Haul OFF is the normal driving position for the
best fuel economy. The overdrive function allows automatic upshifts and
downshifts through gears one through five.
D (Overdrive) with Tow/Haul ON
The Tow/Haul feature improves transmission operation when towing a
trailer or a heavy load. All transmission gear ranges are available when
using Tow/Haul.
To activate Tow/Haul, press the
button on the end of the gearshift
lever.
The TOW HAUL indicator light will
illuminate in the instrument cluster.
Tow/Haul delays upshifts to reduce frequency of transmission shifting.
Tow/Haul also provides engine braking in all forward gears when the
transmission is in the D (Overdrive) position; this engine braking will
slow the vehicle and assist the driver in controlling the vehicle when
descending a grade. Depending on driving conditions and load
conditions, the transmission may downshift, slow the vehicle and control
the vehicle speed when descending a hill, without the accelerator pedal
being pressed. The amount of downshift braking provided will vary based
upon the amount the brake pedal is depressed.
To deactivate the Tow/Haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The TOW HAUL light
will no longer be illuminated.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (Tow/Haul OFF).
Do not use the Tow/Haul feature when driving in icy or slippery
conditions as the increased engine braking can cause the rear
wheels to slide and the vehicle to swing around with the possible loss
of vehicle control.

Removing the key
Turn the ignition off, push the
release lever (located above the
ignition), then turn the key toward
you and remove the key.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
To help avoid personal injury, please read and understand the
limitations of the reverse sensing system as contained in this
section. Reverse sensing is only an aid for some (generally large and
fixed) objects when moving in reverse on a flat surface at “parking
speeds”. Inclement weather may also affect the function of the RSS;
this may include reduced performance or a false activation.
To help avoid personal injury, always use caution when in
reverse and when using the RSS.
This system is not designed to prevent contact with small or
moving objects. The system is designed to provide a warning to
assist the driver in detecting large stationary objects to avoid damaging
the vehicle. The system may not detect smaller objects, particularly
those close to the ground.
Certain add-on devices such as large trailer hitches, bike or
surfboard racks and any device that may block the normal
detection zone of the RSS system may create false beeps.

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
The use of tire sealants may damage your tires.
