emergency towing FORD EXPEDITION 2017 3.G Owners Manual

4. Use the gain adjustment (+ and -)
buttons to increase or decrease the
gain setting to the desired starting
point. A gain setting of 6.0 is a good
starting point for heavier loads.
5. In a traffic-free environment, tow the trailer on a dry, level surface at a speed
of 20-25 mph (30-40 km/h) and
squeeze the manual control lever
completely.
6. If the trailer wheels lock up, indicated by squealing tires, reduce the gain
setting. If the trailer wheels turn freely,
increase the gain setting. Repeat Steps
5 and 6 until the gain setting is at a
point just below trailer wheel lock-up.
If towing a heavier trailer, trailer wheel
lock-up may not be attainable even
with the maximum gain setting of 10.
Explanation of Information Display
Warning Messages
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred.
However, your Ford warranty does not cover
this diagnosis if the fault is with the trailer.
A message indicating a trailer brake
module fault may display in response to
faults sensed by the trailer brake controller,
accompanied by a single tone. If this
message appears, contact an authorized
dealer as soon as possible for diagnosis
and repair. The controller may still
function, but performance may be
degraded.
A message indicating a trailer wiring fault
may display when there is a short circuit
on the electric brake output wire. If this
message displays, accompanied by a
single tone, with no trailer connected, the
problem is with your vehicle wiring
between the trailer brake controller and
the 7-pin connector at the bumper. If the
message only displays with a trailer
connected, the problem is with the trailer wiring. Consult your trailer dealer for
assistance. This can be a short to ground
(such as a chaffed wire), short to voltage
(such as a pulled pin on trailer emergency
breakaway battery) or the trailer brakes
may be drawing too much current.
Points to Remember
Note:
Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result.
• Adjust gain setting before using the
trailer brake controller for the first time.
• Adjust gain setting, using the procedure
above, whenever road, weather and
trailer or vehicle loading conditions
change from when the gain was initially
set.
• Only use the manual control lever for
proper adjustment of the gain during
trailer setup. Misuse, such as
application during trailer sway, could
cause instability of trailer or tow
vehicle.
• Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of
the trailer wheels. Trailer wheels can
lock up on slippery surfaces, resulting
in reduced stability of trailer and tow
vehicle.
• The trailer brake controller is equipped
with a feature that reduces output at
vehicle speeds below 11 mph (18 km/h)
so trailer and vehicle braking is not jerky
or harsh. This feature is only available
when applying the brakes using your
vehicle's brake pedal, not the
controller.
• The controller interacts with the brake
control system and powertrain control
system of your vehicle to provide the
best performance on different road
conditions.

Before using recovery hooks:
•
Make sure all attaching points are
secure and capable of withstanding
the applied load.
• Never use chains, cables or tow straps
with metal hook ends.
• Only use recovery straps that have a
minimum breaking strength two to
three times the gross vehicle weight of
the stuck vehicle.
• Make sure the recovery strap is in good
condition and free of visible cuts, tears
or damage.
• Use a damper device such as a tarp,
heavy blanket or piece of carpet
draped over the recovery strap to help
absorb the energy in the event the
strap breaks.
• Make sure the stuck vehicle is not
loaded heavier than its gross vehicle
weight rating specified on the
certification label.
• Always align the tow vehicle and stuck
vehicle in a straight line (within 10
degrees).
• Keep bystanders to the sides of the
vehicle, at a distance of at least twice
the length of the recovery strap. This
helps avoid injury from the hazard of a
recovery hook or strap breaking, or a
vehicle lurching into their path.
TOWING THE VEHICLE ON
FOUR WHEELS WARNING
If your vehicle has a steering wheel
lock make sure the ignition is in the
accessory or on position when being
towed. Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
•
Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in position
N. If
you cannot move the transmission into
N
, you may need to override it. See
Transmission (page 159).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle. See
Climate Control
(page 112).
Follow these guidelines if you have a need
for recreational towing, for example towing
your vehicle behind a motorhome. These
guidelines prevent damage to your
transmission.
Two Wheel Drive Vehicles
You cannot tow a two wheel drive vehicle
with any wheels on the ground as vehicle
or transmission damage may occur. You
must tow your vehicle with all four wheels
off the ground, for example when using a
car-hauling trailer.
