2021 FORD F-150 ignition

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.
Note: Only perform this procedure at
speeds of approximately 20– 25 mph
(30–40 km/h).
Note: The trailer brake controller reduces
output at vehicle speeds below
11 mph
(18 km/h) so that 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.
Note: Your vehicle's brake system and the
trailer brake system work independently of
each other. Changing the gain setting on the
controller does not affect the operation of
your vehicle's brakes whether you attach a
trailer or not.
Note: With the proper electrical connection,
pressing your vehicle brake pedal or using
the manual control lever illuminates both
trailer and vehicle brake lamps.
Note: When you switch the engine off, the
controller output is disabled and the display
and module shut down. The controller
module and display turn on when you switch
the ignition on. Adjusting the Trailer Brake Gain
Increase or decrease the amount
of gain in set increments.
A
Slide the control to engage the
trailer brakes.
B
Note: Adjust gain setting before using the
trailer brake controller for the first time.
Note: The gain should be set to provide the
maximum trailer braking assistance while
making sure the trailer wheels do not lock
when using the brakes. Locked trailer wheels
may lead to trailer instability.
Note: Setting adjustments are saved when
a trailer profile is selected.
Note: If you have installed an aftermarket
trailer brake controller in addition to the
integrated trailer brake controller, set the
gain on the integrated trailer brake controller
to zero.

JUMP STARTING THE VEHICLE
JUMP STARTING PRECAUTIONS WARNING: Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately. WARNING:
Use only adequately
sized cables with insulated clamps. WARNING:
Make sure that the
cables are clear of any moving parts and
fuel delivery system parts. WARNING: Connect batteries with
only the same nominal voltage. WARNING: If the engine is running
while the hood is open, stay clear of
moving engine components. Failure to
follow this warning could result in serious
personal injury or death.
Do not attempt to push-start an automatic
transmission vehicle. This could cause
transmission damage.
Do not disconnect the battery of the
disabled vehicle. This could damage your
vehicle's electrical system.
PREPARING THE VEHICLE
Use only a 12 volt supply to start your
vehicle.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the
two vehicles do not touch.

RECOVERY TOWING
ACCESSING THE FRONT TOWING
POINT
WARNING: Using recovery hooks
is dangerous and should only be done by
a person familiar with proper vehicle
recovery safety practices. Improper use
of recovery hooks may cause hook failure
or separation from the vehicle and could
result in serious injury or death. WARNING:
Slowly remove the
slack from the recovery strap prior to
pulling. Failure to do so can introduce
significantly higher loads which can
cause the recovery hooks to break off, or
the recovery strap to fail which can cause
serious injury or death. WARNING:
Never link two straps
together with a clevis pin. These heavy
metal objects could become projectiles
if the strap breaks and can cause serious
injury or death. WARNING:
Switch the ignition off
before removing the recovery hook.
Failure to do so could result in personal
injury. WARNING: The recovery hook can
become hot. Let the recovery hook cool
down before removing it. Failure to do
so could result in personal injury.
Your vehicle has frame-mounted front
recovery hooks.
Note: Do not apply a load to the recovery
hooks that is greater than the gross vehicle
weight rating of your vehicle. Before using recovery hooks:
•
Make sure all attaching points are
secure and capable of withstanding
the applied load.
• Do not 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, and
place it 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.
• 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 YOUR VEHICLE
PRECAUTIONS
Use the following guidelines when towing
your vehicle. Failure to follow this
instruction could result in vehicle damage
not covered by the vehicle warranty.
Note:
Make sure you properly secure your
vehicle to the tow vehicle.
Note: If you are unsure of the vehicle ’s
configuration, contact an authorized dealer.
RECREATIONALLY TOWING
YOUR VEHICLE - 4X4 WARNING: Do not disconnect the
battery when recreationally towing your

Placing the transfer
case in its neutral position could cause
your vehicle to freely roll. Make sure you
press and hold the brake pedal and the
vehicle is in a secure, safe position when
you place the transfer case in its neutral
position.
Follow these guidelines if you have a need
for recreational towing. An example of
recreational towing would be towing your
vehicle behind a motorhome. These
guidelines are to make sure that you do
not damage the transmission. You can only tow your vehicle with all
wheels on the ground by placing the
transfer case in its neutral position and
engaging the recreational tow feature.
Perform the following steps after
positioning your vehicle behind the tow
vehicle and properly securing them
together.
Note:
Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
Note: Failure to put the transfer case in its
neutral position can damage vehicle
components.
Note: You can check the towing status at
any time by opening the driver door or
turning the ignition to the accessory or on
position. Neutral Tow Enabled Leave
Transmission in Neutral
