2020 FORD F-450 emergency towing

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.
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.
TRAILER BRAKE MODULE FAULT
Displays 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 with
degraded performance.
WIRING FAULT ON TRAILER
Displays when there is a short circuit on
the electric brake output wire.
If this message displays, with no trailer
connected, the problem is with your vehicle
wiring or trailer brake controller. Contact
an authorized dealer.
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.
• Adjust gain setting, using the procedure
above, whenever road, weather, 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 active
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.

•
Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Your vehicle may be equipped with a
temporary or conventional spare tire. A
"temporary" spare tire is different in size
(diameter or width), tread-type
(All-Season or All Terrain) or is from a
different manufacturer than the road tires
on your vehicle. Consult information on the
tire label or Safety Compliance label for
limitations when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
you remove the trailer from the water.
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 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability. Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
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 neutral (N).
If you cannot move the transmission
into neutral (N), you may need to
override it. See
Transmission (page
201).
• 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 139).

•
Inspect exhaust system for damage or
looseness.
• Inspect undercarriage fasteners. If any
are loose or damaged, tighten or
replace ensuring that the proper torque
specification is used.
• Inspect the tires for any cuts in the
tread or sidewall area. Also inspect the
sidewall for any bulge indicating
damage to the tire.
• Inspect the wheels for dents, cracks,
or other damage.
• Refit the front license plate if removed
previously.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least
1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Capacities and Specifications
(page
437).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle. Note:
Engine damage can occur if water
enters the air filter.
For Vehicles without Tremor Off-
Road Package
Note: Driving through standing water can
cause vehicle damage.
Note: Drive through water in an emergency
only and not as part of normal driving.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
