System Operation
The following warnings or difficulties may
occur during system operation. Tips to
resolve them are listed in the following
section.
Pro Trailer Backup Assist™ System is Not
Available or Trailer Reverse Guidance
System is Not Available:
• The system relies on many
sub-systems in your vehicle to correctly
operate. If those sub-systems are not
correctly operating, the system may
not be available.
• Low battery voltage is a condition that
prevents the system from operating.
Please make sure the battery is
correctly charged if the system is not
available.
• If the message continues to display,
see your authorized dealer for service. Pro Trailer Backup Assist™ Driving

•
The steering system needs to learn
internal parameters to fully enable the
feature. Drive your vehicle straight
forward above 25 mph (40 km/h) for
approximately 5 minutes.
• This may occur when your vehicle is
new, the battery voltage is too low, the
battery has been disconnected or your
steering system has been serviced.

Knob to Exit or Trailer Reverse Guidance
Sensor Not Detected Refer to Owner's
Manual Press OK to Exit:
• Check that the 12 way connector is fully
inserted into the 12 way socket. The red
rubber seal is not visible when the
connector is fully inserted.
• Check that the wiring harness sensor
connection is fully inserted at the trailer
sensor.
• Check for damaged wiring between the
12 way connector and the trailer sensor.
• Only one sensor can be connected to
your vehicle at a time. If you have a 7/12
pin connector in the truck bed and in
the bumper, check to make sure that
only one sensor is connected.
Note: If you did not purchase the fifth wheel
prep pack, you need to replace the 7/4 way
trailer connector in your bumper with a 7/12
pin connector. See your authorized dealer.

•
If the vehicle has not moved during this
key cycle, it must be driven forward to
initialize the sensing system.
• Extended operation at speeds below
1 mph (1 km/h) may cause the sensing

complete calibration.
System does not reverse straight:
• Verify sensor is correctly installed. See
Fifth Wheel and Gooseneck Trailer
Sensor Installation.
• Factors such as the hitch connection,
road camber, road slope and
compliance in the trailer suspension
can influence how straight the system
is able to reverse the trailer when the
knob is not turned. You can
compensate for the trailer drifting to
the right or left by slowly turning the
knob until the trailer is following your
preferred path and then holding the
knob in that position. System consistently shows Pro Trailer

the information display.
• The system may need to be
recalibrated. The system can be
recalibrated by using the information
display to delete the trailer and
repeating the setup process. If the
same sensor is installed on another
trailer, create a new trailer in the
information display and complete the
setup and calibration process for the
new trailer. If using the same sensor on
multiple trailers, disconnect the 7/12
pin connector when switching trailers.
See Setting Up The System.

CHANGING THE ENGINE AIR
FILTER - 7.3L
WARNING: To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
Note: Operating your vehicle in heavy
snowfall or extreme rain conditions may
allow excessive amounts of snow or water
into the air intake system. This could plug
or soak the air filter that could cause the
engine to lose power or shut down.
When replacing the air filter element, use
a Motorcraft® air filter element. See
Motorcraft Parts
(page 443).
Note: Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage
may not be covered by the vehicle Warranty.
Change the air filter element at the correct
interval. See
Scheduled Maintenance
(page 565). 1. Locate the mass air flow sensor
electrical connector on the air outlet
tube. Disconnect the mass air flow
sensor electrical connector. 2. Reposition the locking clip on the
connector, squeeze the connector and
pull it off of the air outlet tube. 3.
Clean the area from around the air tube
to the air cover connection to prevent
debris from entering the system. Next,
loosen the bolt on the air tube clamp
so the clamp is no longer snug to the
air tube. It is not necessary to
completely remove the clamp.
4. Pull the air tube off from the air cleaner
housing.

housing and cover. Ensure that you
align the tabs on the edge properly into
the slots.
9. Slip the air tube onto the air filter housing and tighten the air-tube clamp
bolt snugly. Do not over tighten
air-tube clamp bolt. 10. Reconnect the mass air flow sensor
electrical connector to the outlet
tube. Make sure the locking tab on
the connector is in the locked
position.
