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 vehicle 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.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.
Adaptive Steering (If Equipped) WARNING
The adaptive steering system has
diagnostic checks that continuously
monitor the system. If a fault is
detected a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. This warning
message may clear if the fault is no longer
present. If an adaptive steering system
warning message appears each time you
start your vehicle, have the system
checked as soon as possible. The adaptive steering system continually
changes the steering ratio with changes to
vehicle speed, optimizing the steering
response in all conditions. The system also
changes when you switch on the
transmission tow/haul feature. When you
select the tow/haul button, the adaptive
steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds,
while maintaining the ease of parking and
maneuverability at low speeds.
Note:
The adaptive steering system is
designed with a locking device. With the
lock engaged, the adaptive steering system
remains mechanically locked at a fixed
steering ratio. You may also notice a click
when you switch the vehicle on or after you
switch it off, as the lock disengages or
engages.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system automatically shuts down and you
retain normal steering function with a fixed
steering ratio. During this time it is possible
that the steering wheel may not be straight
when the vehicle is driving straight ahead.
In addition, the driver may notice that the
steering wheel angle required to steer the
vehicle may be different.
Note: During parking maneuvers, the
adaptive steering system balances the driver
work load for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device may engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.

Note:
It is recommended that you turn the
collision warning system off if a snow plow
or similar object is installed in such a way
that it may block the radar sensor. Your
vehicle will remember the selected setting
across key cycles.
Note: When possible, the manufacturer
recommends using the highest sensitivity
setting. If warnings are too frequent, you can
reduce your system's sensitivity. Reduced
sensitivity causes fewer and later system
warnings. See General Information (page
111). Blocked Sensors If a blocked sensor message appears in the
information display, dirt, water, or an object
is blocking the sensor. The sensor is
located behind a cover near the driver side
of the lower grille. If anything blocks the
sensor, your vehicle cannot see through
the sensor, and the collision warning
system will not work. Possible causes for
the blocked sensor message and corrective
actions are listed below.

System Limitations
WARNING
The collision warning system
’s brake
support only reduces collision speed
if you first apply your brakes. You
must brake as you would in any typical
braking situation. Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision warning.
These include:
•
Stationary vehicles or vehicles moving
below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
• Severe weather conditions (see
blocked sensor section).
• Debris build-up on the grille near the
headlamps (see blocked sensor
section).
• Small distance to vehicle ahead.
• Large steering wheel and pedal
movements (very active driving style).
Damage to the front end of your vehicle
may alter the radar sensor's coverage area.
This may result in missed or false collision
warnings. Have an authorized dealer check
your radar sensor for proper coverage and
operation.

Sticker lost:
•
Check for the following if you receive
the lost sticker message while using
the system.
•Stop your vehicle as soon as the
message displays.
• Make sure the sticker is visible in
the rear view camera image.
• Clean the sticker and camera to
make sure they are unobstructed.
• Remove any items that may be
blocking the view of the sticker.
Depending on your trailer
configuration and any equipment
mounted to your trailer it is possible
for the sticker to be blocked from
view of the camera as it rotates on
the hitch ball but not be blocked
during setup. Remove the
obstruction if possible. It will be necessary to remove the sticker
from it’
s current location if the
obstruction cannot be cleared and
place a new sticker that will be
visible to the camera in all positions
of the trailer behind your vehicle.
• You can change your sticker
location by going into the trailer
menu, selecting trailer options,
selecting change trailer settings
and then selecting the change
sticker option. The previous sticker
must be removed. ONLY ONE
STICKER SHOULD BE PLACED
ON THE TRAILER FOR CORRECT
SYSTEM FUNCTION.
• The camera system uses the
entered measurements to help
locate the sticker. Inaccurate
measurements will reduce the
system ’s ability to locate the
sticker. Check the measurements
entered into the system are correct.
Refer to the step 4 of Trailer
Reverse Guidance setup for
instructions on measurements.
• You can change your measurement
by going into the trailer menu,
selecting trailer options, selecting
change trailer setting and then
selecting the change sticker option.
Disregard the prompt to remove
this sticker and continue to the next
step if you only plan to update the
measurements for the current
sticker location.
System will not backup straight:
• Factors such as the drawbar
connection to the hitch receiver, road
camber, road grade and compliance in
the trailer suspension can influence
how straight the system is able to back
your trailer when the wheel is not
turned. You can compensate for the
trailer drifting to the right or left by

Calculating the Maximum
Loaded Trailer Weight for Your
Vehicle
1. Start with the gross combined weight rating for your vehicle
model and axle ratio. See the
previous chart.
2. Subtract all of the following
that apply to your vehicle: •
Vehicle curb weight
• Hitch hardware weight, such as
a draw bar, ball, locks or weight
distributing hardware
• Driver weight
• Passenger(s) weight
• Payload, cargo and luggage
weight
• Aftermarket equipment weight.
280

Once the trailer is level or slightly nose
down toward the vehicle:
•
Lock the bar tension adjuster in place.
• Check that the trailer tongue securely
attaches and locks onto the hitch.
• Install safety chains, lighting, and trailer
brake controls as required by law or the
trailer manufacturer.
Fifth-wheel Trailer Hitch (If Equipped)
Note: The mounting pads in the bed are
specifically designed for certain fifth-wheel
trailer hitches and gooseneck ball hitches.
Do not use these mounting pads for other
purposes.
Note: Contact an authorized dealer to
purchase gooseneck and fifth-wheel hitches
that are compatible with your vehicle.
Your vehicle may be equipped with a
fifth-wheel prep package. This package
enables your vehicle to accept certain
fifth-wheel trailer hitches and gooseneck
ball hitches. The fifth-wheel trailer hitch
attaches to the four mounting pads in the
pick-up bed. An optional 7-pin trailer wiring
connector may be in the bed as well. The
gooseneck ball hitch is a separate
mounting pad from the fifth-wheel hitch,
located in the center of the bed.
Shorter pick-up boxes, such as the 6½-foot
box on the F-250 and F-350, provide less
clearance between the cab and the
fifth-wheel and gooseneck trailer
compared to longer box pick-ups, such as
an 8-foot box on the F-250 or F-350. When
selecting a trailer and tow vehicle, it is
critical to check that this combination
provides clearance between the front of
the trailer and tow vehicle for turns up to
90 degrees. Failure to follow this recommendation could result in the trailer
contacting the cab of the tow vehicle
during tight turns that are typical during
low-speed parking and turning maneuvers.
This contact could result in damage to the
trailer and tow vehicle.
Safety Chains
Note:
Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle
hitch.
To connect the safety chains, cross the
chains under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Trailer Brakes WARNING
Do not connect a trailer's hydraulic
brake system directly to your
vehicle's brake system. Your vehicle
may not have enough braking power and
your chances of having a collision greatly
increase. Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1500 pounds (680 kilograms)
when loaded.
