2021 FORD F-150 tires

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.

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.
472
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Driving Hints

Vehicles used to traverse water should be
periodically inspected for signs of water
ingestion in all of the vehicle's fluids. If
water is found inside your vehicle fluids,
service your vehicle or see an authorized
dealer.
Avoid Getting High-Centered
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 and getting high-centered.
Freeing A Stuck Vehicle
WARNING: Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Recovery hooks are mounted to the
vehicle's structure and are used to pull out
the vehicle from a surface or location when
stuck. Recover your vehicle using various
towing apparatus attached to your
recovery hook such as winch, open hook,
or strap.
Note: Do not use recovery hooks to
recreationally tow your vehicle. See
Recreationally Towing Your Vehicle (page
490
).
Note: Do not rock your vehicle if the engine
is not at normal operating temperature as
damage to the transmission could occur.
Note: Do not rock your vehicle for more
than a minute as damage to the
transmission and tires could occur or the
engine could overheat.
If you are unable to free your vehicle call
roadside assistance. See
Roadside
Assistance (page 483). Crossing A Ravine, Gully, Ditch,
Washout Or Rut
Review the path ahead before attempting
to cross any obstacle.
Driving Over Logs
Review the path ahead before attempting
to cross any obstacle.
DRIVING YOUR VEHICLE AT HIGH
SPEEDS - RAPTOR
If you plan on using your vehicle for severe,
high speed off-road use, we recommend
the following:
•
Equipping your vehicle with the safety
equipment appropriate for off-road
recovery.
• Using personal safety equipment,
including a certified helmet and
approved neck restraint device.
• Doing a low speed reconnaissance run
in unfamiliar areas to become aware
of any obstacles that you could
encounter.
Your vehicle can incur damage if driven
beyond its capabilities. Skid plates, shock
guards and running boards are designed
to help limit damage to vital components
and exterior finishes, but cannot prevent
all damage if driven in extreme off-road
conditions. Damage to skid plates, shock
guards, running boards and exterior
finishes as well as bent, cracked or broken
body, frame and chassis components may
not be covered by warranty.

Using Trail Control
Trail Control provides you the ability to
maneuver the vehicle without using the
throttle and brake pedals.
The system controls acceleration and
braking in difficult off-road environments,
which allows you to focus on steering. See
Trail Control (page 324).
Trail Control Performance:
• Manages wheel slip to maximize
traction.
• Provides braking to maximize traction
in descents.
Using Trail One Pedal Drive
(If
Equipped)
Trail one pedal drive allows you to
accelerate and brake using only the
accelerator pedal.
Use this when driving over large obstacles,
such as rocks or logs, to help maintain a
constant vehicle speed.
In 4H, the system offers lift pedal braking
and auto hill hold functionality. See
What
Is Trail One Pedal Drive (page 325).
Note: Trail one pedal drive is only available
when the vehicle is in 4H or 4L.
AFTER DRIVING YOUR VEHICLE
OFF-ROAD - RAPTOR WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death. WARNING:
Always re-inflate tires
to recommended tire pressures before
the vehicle is operated on-road. The
recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door.
Driving off-road places more stress on your
vehicle than most on-road driving. After
driving off-road, check for damage and, if
necessary, have your vehicle repaired by
an authorized dealer.
Inspect the underbody of your vehicle by
checking tires, body structure, steering,
suspension, and exhaust system for
damage.
Check the radiator for mud and debris and
clean as needed.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
After operation in mud, sand, water, or
similar dirty conditions, inspect the
underbody and clean your vehicle.
AFTER DRIVING YOUR VEHICLE
OFF-ROAD WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death.

damage.
Check the radiator for mud and debris and
clean as needed.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
After extended operation in mud, sand,
water, or similar dirty conditions, inspect
the underbody and clean your vehicle as
soon as possible.
If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material.
Impacted material can cause vibrations
while driving and wheel imbalance.
Remove the material to resolve the
problem.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below approximately
-13°F (-25°C)
. DRIVING ON SNOW AND ICE WARNING:
If you are driving in
slippery conditions that require tire
chains or cables, then it is critical that
you drive cautiously. Keep speeds down,
allow for longer stopping distances and
avoid aggressive steering to reduce the
chances of a loss of vehicle control
which can lead to serious injury or death.
If the rear end of your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
On ice and snow, you should drive more
slowly than usual. Your vehicle has a four
wheel anti-lock brake system, do not pump
the brake pedal.
See Anti-Lock Braking
System Limitations (page 308).
BREAKING-IN
Your vehicle requires a break-in period. For
the first 1,000 mi (1,600 km), avoid driving
at high speeds, heavy braking, aggressive
shifting or using your vehicle to tow. During
this time, your vehicle may exhibit some
unusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuel
consumption:
• There is no need to wait for your engine
to warm up. The vehicle is ready to
drive immediately after starting.
• Your fuel consumption should improve
throughout your hybrid's break-in
period.
• Accelerate and slow down in a smooth,
moderate fashion.
476
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Driving Hints

•
Moderate braking is particularly
important since it allows you to
maximize the energy captured by the
regenerative braking system.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Driving on flat terrain.
• Drive at reasonable speeds and
observe posted speed limits.
• Shut all windows when driving at high
speeds.
• Combine errands and minimize
stop-and-go driving.
• Drive with the tonneau cover installed
if your vehicle comes with one.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Perform all scheduled maintenance.
Note: Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.
Avoid these actions; they reduce your fuel
consumption:
• Revving the engine.
• Aggressive driving increases the
amount of energy required to move
your vehicle.
• Driving in lower temperatures during
the first 5–10 mi (12 –16 km) of driving.
• Idle for periods longer than one minute.
• Use the air conditioner or front
defroster. •
Adding certain accessories to your
vehicle like bug deflectors, rollbars,
light bars, running boards, ski racks or
luggage racks.
• Use the speed control in hilly terrain.
• Using fuel blended with alcohol.
• Drive a heavily loaded vehicle or tow a
trailer.
• Driving with the wheels out of
alignment.
DRIVING IN SPECIAL
CONDITIONS
EMERGENCY MANEUVERS
In an unavoidable emergency where you
must make a sudden sharp maneuver, turn
the steering wheel only as rapidly and as
far as required to avoid the emergency.
Apply smooth pressure to the accelerator
pedal or brake pedal as needed. Avoid
abrupt steering, acceleration and braking
changes. Abrupt changes could increase
the risk of vehicle roll over, loss of vehicle
control and personal injury. If possible, use
any available road surfaces to bring your
vehicle under control.
FLOOR MATS WARNING:
Use a floor mat
designed to fit the footwell of your
vehicle that does not obstruct the pedal
area. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Pedals that cannot
move freely can cause loss of vehicle
control and increase the risk of serious
personal injury.
