– FREQUENTLY ASKED
QUESTIONS
Why does the trailer not reverse
straight?
Verify the sensor is correctly installed.
Other factors such as the hitch
connection, road camber, road slope
and trailer suspension could influence
how straight the system can reverse
the trailer when the control 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 desired path and then
holding the knob in that position.
Why does the system not detect a
sensor? There could be an issue with the
connection, the wiring harness could
be damaged, you could have multiple
sensors connected or the sensor could
be incorrectly installed. 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. Also check that the
wiring harness sensor connection is
fully inserted at the trailer sensor, and
check for damaged wiring between
the 12-way connector and the trailer
sensor. Also, check that the sensor is
installed on a vertical surface with the
arrows pointing straight up. What does it mean if the system
remains on one message for an
extended time during calibration when
setting up the system with the sticker?
The camera could need to be cleaned,
the sticker could be blocked, the
drawbar could be outside the allowed
range of 4–19 in (10–48 cm) or you
could need to move to a different area
to change the lighting and background.
Verify the sticker is in the proper
location. See
Applying the Trailer
Reversing Aid Sticker (page 448).
You can move to a different area or
change the direction you are driving or
setup the system at a different time
of day. Some trailers are not
compatible with the sticker and
camera system. If the issue persists
with the sticker setup, you may choose
to setup the trailer with a sensor.
What does it mean if the system pauses
during calibration? There could be steering input or trailer
movement during the straight drive
portion of the calibration process.
What does it mean if the system
remains on one message for an
extended time during calibration when
setting up the system with the sensor? The sensor could be incorrectly
installed, the trailer length could be
outside the allowed range or the road
surface could be too rough or bumpy.
What does it mean if the system
displays hold steering steady during
turn? Part of the calibration process for the
sticker setup requires a steady turn. If
you are continually moving the
steering wheel during the turn, this
delays the calibration process. To
enable the calibration process, hold
the steering wheel at the same
position when turning.

What does it mean when the system
tells you to take control of the steering
wheel?
The system is no longer steering the
vehicle and you must take over
steering. There are four reasons the
system could display this message.
The first reason the system could
display this message is that you have
touched the steering wheel when the
system is steering. The second reason
the system could display this message
is that you have exceeded the
maximum speed for the feature. The
third reason the system could display
this message is that the trailer is not
detected. The final reason the system
could display this message is that an
internal condition for system operation
is not met that requires your vehicle to
return to manual control of the
steering.
How do I use a sticker if I have
previously setup a trailer with the
sensor? Disconnect the sensor wiring and add
a new trailer to the system and follow
the instructions for setup with a
sticker. See Applying the Trailer
Reversing Aid Sticker (page 448). If
your vehicle does not support the
sticker option, the touchscreen
instructs you to install the sensor
again.
What if I want to use a sensor for the
trailer instead of a sticker? Install the sensor and connect the
sensor wiring before adding the new
trailer to the system. You must
connect the sensor before you add the
trailer. If your vehicle did not come with
a sensor, you can purchase one from
your authorized dealer. What does it mean if the system does
not detect a trailer that is setup with a
sticker?
The system requires a clear view of the
sticker placed on the trailer. You must
keep the camera lens and sticker clean
for the system to correctly operate. If
the system cannot initially detect the
trailer, it could be necessary for you to
change the lighting conditions by
moving your vehicle and trailer or
waiting until the conditions change.
See
Applying the Trailer Reversing
Aid Sticker (page 448). Some trailers
are not compatible with the sticker
and camera system. If the system
consistently does not detect the trailer
with the sticker setup, you may choose
to setup the trailer with a sensor.
Note: The system is designed to be used
with the same trailer connection every time
you choose the trailer from the touchscreen.
When using a different drawbar or a
different pin hole on drawbars with more
than one, connecting the drawbar to your
vehicle affects the trailer position and you
may need to repeat the trailer setup and
calibration process.

5. When with other vehicles, it is
recommended that communication is
used, and the lead vehicle notify other
vehicles of obstacles that could cause
potential vehicle damage.
6. Always keep available ground clearance in mind and pick a route that
minimizes the risk of catching the
underside of the vehicle on an obstacle.
7. When negotiating low speed obstacles,
applying light brake pressure in
conjunction with the throttle will help
prevent the vehicle from jerking and
will allow you to negotiate the obstacle
in a more controlled manner. Using 4L
will also help with this.
8. Off-roading requires a high degree of concentration. Even if your local law
does not prohibit alcohol use while
driving off-road, Ford strongly
recommends against drinking if you
plan to off-road.
Crossing Obstacles
• Review the path ahead before
attempting to cross any obstacle. It is
best if the obstacle is reviewed from
outside the vehicle so that there is a
good understanding of terrain condition
both in front of and behind the
obstacle.
• Approach obstacles slowly.
• If a large obstacle such as a rock
cannot be avoided, choose a path that
places the rock directly under the tire
rather than the undercarriage of the
vehicle. This will help prevent damage
to the vehicle.
• Ditches and washouts should be
crossed at a 45° angle, allowing each
wheel to independently cross the
obstacle. Hill Climbing WARNING:
Extreme care should
be used when steering the vehicle in
reverse down a slope so as not to cause
the vehicle to swerve out of control.
• Always attempt to climb a steep hill
along the fall line of the slope and not
diagonally.
• If the vehicle is unable to make it up
the hill, DO NOT attempt to turn back
down the slope. Place the vehicle in
low range and slowly back down in
reverse.
• When descending a steep slope, select
low gear and engage hill descent
control. Use the throttle and brake
pedals to control your descent speed.
Note: Hill descent control is functional in
reverse and should be used in this situation.
DRIVING OFF-ROAD - RAPTOR
Driving In Snow and Ice WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Make sure you allow sufficient distance
between your vehicle and other vehicles
for stopping.
Driving In Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.

Driving In Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud.
After driving through mud, clean your
vehicle. Excess mud stuck on the wheels
and tires and rotating components can
cause an imbalance and result in damage.
Note:
The vehicle brakes are less effective
when wet or muddy.
Driving Over Rocks and Gravel
Never attempt to straddle a rock that is
large enough to strike your axles or
undercarriage.
Leave a generous gap between your
vehicle and other vehicles to minimize the
risk of damage. Avoid dust clouds as they
reduce visibility.
Climbing A Hill WARNING: Extreme care should
be used when steering the vehicle in
reverse down a slope so as not to cause
the vehicle to swerve out of control.
Do not drive over the crest of a hill without
seeing what conditions are on the other
side. Do not drive in reverse over a hill
without the aid of an observer.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Note: Too much acceleration can cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control. Driving Through Water WARNING:
Do not attempt to
cross a deep, fast flowing body of water.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
The key to a safe crossing is the water
depth, current and bottom of the water's
condition. On soft bottoms, the vehicle
sinks in, effectively increasing the water
level on the vehicle. Make sure to consider
this when determining the depth of water.
Determine the depth and speed of the
current before attempting a water crossing.
Be aware that obstacles and debris could
be beneath the water ’s surface.
Note: Cross flowing water at an angle
heading slightly upstream.
Note: Tread lightly and avoid damage to
the environment.
Water can cause permanent damage that
may not be covered by your vehicle
warranty. See
Driving Through Water
Limitations (page 474).
Note: Failure to follow the recommended
speeds can result in vehicle damage.
Muddy waters can reduce the cooling
system effectiveness by depositing debris
into the radiator.
High currents even in shallow water can
wash the dirt out from around your tires or
push your vehicle across slippery rocks or
surfaces.
Do not cross any body of water that is fast
flowing and rising.
