2021 FORD F-150 fuel pressure

Biodiesel
WARNING: Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
Note: Do not use home heating oil,
agricultural fuel, raw fats and oils, waste
cooking greases, biodiesel greater than 20%
or any diesel not intended for highway use.
Damage to the fuel injection system, engine
and exhaust catalyst, and diesel particulate
filter can occur if you use an improper fuel.
Red dye is used to identify fuels intended
for agricultural and non-highway use.
You can operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
• Confirm the biodiesel content of the
fuel to be B20 (20% biodiesel) or less.
• Only use biodiesel fuel of good quality
that complies with industry standards.
• Follow the recommended service
maintenance intervals. See
General
Maintenance Information (page 664).
• Do not store biodiesel fuel in the fuel
tank for more than 1 month.
• Consider changing brands or reducing
biodiesel content if you have cold
temperature fuel gelling issues or a
frequently appearing LOW FUEL
PRESSURE message. Use of biodiesel in concentrations greater
than 20% can cause damage to your
vehicle, including engine and/or exhaust
after-treatment hardware (exhaust
catalyst and particulate filter) failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that could
result in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
We recommend SAE 5W-40 oil for fuels
with greater than 5% biodiesel (B5). For
more information about oil change
intervals and other maintenance when
operating on biodiesel.
See Special
Operating Conditions Scheduled
Maintenance
(page 675).
Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in diesel fuel. Ask the service station
attendant to confirm the biodiesel content
of diesel fuel, if you do not see a label on
the fuel pump.
If you plan to park or store your vehicle for
more than 1 month, then you should empty
your vehicle fuel tank of biodiesel fuel. You
should fill the tank with a pure
petroleum-based diesel fuel and run your
vehicle for a minimum of 30 minutes.
Note: Degraded or oxidized biodiesel can
damage fuel system seals and plastics and
corrode steel parts.
During cold weather, if you have problems
operating on biodiesel, you may need to
use diesel fuel with lower biodiesel
content, try another brand or discontinue
the use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add any
aftermarket additives to your fuel if you
use a high-quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
injector system or engine.

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.

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.
