ignition FORD F-150 2020 Workshop Manual

Filling the Fuel Tank
For consistent results when refueling:
•
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Your vehicle calculates fuel economy
figures through the trip computer average
fuel function. See Information Displays
(page 120).
The first
1,000 mi (1,500 km) of driving is
the break-in period of the engine. A more
accurate measurement is obtained after
2,000 mi (3,000 km)
.
1. Completely fill the fuel tank and record
the initial odometer reading.
2. Each time you fill the fuel tank, record the amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per
gallon) fuel consumption, divide miles
traveled by gallons used. Keep a record for at least one month and
record the type of driving, for example city
or highway. This provides an accurate
estimate of your vehicle
’s fuel economy
under current driving conditions. Keeping
records during summer and winter shows
how temperature impacts fuel economy.
Conditions
• Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Avoid adding accessories that increase
aerodynamic drag to your vehicle such
as bug deflectors, car top carriers and
ski or bike racks.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes. WARNING: Do not allow people or
animals in truck beds that have
modifications, such as bed covers or
slide-in campers, when the engine is
running. Exhaust fumes are toxic. Failure
to follow this instruction could result in
personal injury or death.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 333).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Your vehicle warranty does not cover
resulting component damage.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.

Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly, for example, the bulb
does not work, or if the OBD-II system has
determined that some of the emission
control systems have not been properly
checked. In this case, the vehicle is not
ready for I/M testing.
If you have just serviced the vehicle ’s
engine or transmission or the battery has
recently run down or you have replaced it,
the OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.
SELECTIVE CATALYTIC
REDUCTANT SYSTEM - DIESEL
Your vehicle may have a selective catalytic
reduction system. The system helps reduce
emission levels of oxides of nitrogen from
the exhaust system. The system
automatically injects diesel exhaust fluid
into the exhaust system to enable correct
selective catalytic reduction system
function.
Note: Selective catalytic reduction systems
are not fitted to vehicles in markets where
only high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctly
you must maintain the diesel exhaust fluid
level.
A warning message appears in the
information display when the diesel
exhaust fluid level is low. If a warning
message appears, refill the diesel exhaust
fluid tank as soon as possible. See
Information Messages (page 132).
207
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Engine Emission Control

Note:
For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you repair the contaminated system.
To service a contaminated or inoperative
system, see an authorized dealer.
DIESEL PARTICULATE FILTER
The filter forms part of the emissions
reduction system on your vehicle. It filters
harmful diesel particulates (soot) from the
exhaust gas.
Regeneration WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard.
Note: Avoid running out of fuel.
Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function. Your vehicle will carry
out this process automatically. If your journeys meet one of the following
conditions:
•
You drive only short distances.
• You frequently switch the ignition on
and off.
• Your journeys contain a high level of
acceleration and deceleration.
You must carry out occasional trips with
the following conditions to assist the
regeneration process:
• Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.
• Avoid prolonged idling and always
observe speed limits and road
conditions.
• Do not switch the ignition off.
• Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM.
Oxidation Catalytic Converter and
Diesel Particulate Filter System
(If
Equipped) WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel
particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.

the gear you desire. Only the current gear
displays. Use the buttons on the gearshift
lever or steering wheel to manually select
gears. Press the + button to upshift or the
– button to downshift. Return the
transmission to a different gearshift
position to deactivate manual control. Progressive Range Selection
Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This could provide you with
an improved driving experience, for
example, in slippery conditions or when
experiencing a steep slope.
With the transmission in drive (D), press
the
– button to active PRS. The available
and selected gears are indicated on the
instrument cluster.
All available gears display with the current
gear indicated. Press the

the transmission automatically shifts
between the available gears. Press the
+
button to unlock gears to allow the
transmission to shift to higher gears. The
transmission shifts automatically within
the gear range you select. Brake-Shift Interlock WARNING:
When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Do not drive your
vehicle until you verify that the
stoplamps are working.
Your vehicle is equipped with a brake-shift
interlock feature that prevents moving the
gearshift lever from park (P) when the
ignition is in the on position and the brake
pedal is not pressed.
If you cannot move the gearshift lever out
of park (P) position with the ignition in the
on position and the brake pedal pressed,
a malfunction may have occurred. It is
possible that a fuse has blown or your
vehicle ’s brake lamps are not operating
properly.
See Fuse Specification Chart
(page 344).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure allows you to move the gearshift
lever from park (P):
Column-shifter
1. Apply the parking brake and switch off
your vehicle.
2. Move the steering column to the full down and full rearward position
(toward the driver ’s seat).

It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than
attempt a sudden return to the road which
could cause your vehicle to slide sideways
out of control or roll over. Remember, your
safety and the safety of others should be
your primary concern.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your
vehicle (i.e. turn the steering wheel only as
rapidly and as far as required to avoid the
emergency). Excessive steering can result
in loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are
required. Avoid abrupt steering,
acceleration and braking. This could result
in an increased risk of vehicle roll over, loss
of vehicle control and personal injury. Use
all available road surface to bring your
vehicle to a safe direction of travel.
In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of
surface to another (i.e. from concrete to
gravel) there can be a change in the way
your vehicle responds to a maneuver (i.e.
steering, acceleration or braking).
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly
and avoid excessive wheel slip.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Low gear operation
can maximize the engine and transmission
cooling capability.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could become stuck
to the point that assistance may be
required from another vehicle. Remember,
you may be able to back out the way you
came if you proceed with caution.
Mud and Water
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can
lose traction in slick mud. If your vehicle
does slide, steer in the direction of the slide
until you regain control of your vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts can cause an imbalance that
could damage drive components.
Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, try the brakes. Wet
brakes do not stop your vehicle as
effectively as dry brakes. Drying improves
by applying light pressure to the brake
pedal while moving slowly.
Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary.
228
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Four-Wheel Drive (If Equipped)

Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it cannot stop any faster as
braking occurs at all four wheels. Do not
become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See Hints on Driving With
Anti-Lock Brakes (page 234).
If Your Vehicle Gets Stuck In Mud or
Snow WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute, damage to the transmission
and tires may occur or the engine may
overheat.
Parking WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death.
On some four-wheel drive vehicles, when
the transfer case is in the neutral (N)
position, the engine and transmission
disconnect from the rest of the driveline.
Therefore, your vehicle is free to roll even
if it is parked. Do not leave your vehicle
unattended with the transfer case in the
neutral (N) position. Set the parking brake
fully and turn off the ignition when leaving
your vehicle.
Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty. For this reason,
we strongly recommend that you do not
make modifications such as adding or
removing parts (i.e., lift kits or stabilizer
bars) or by using replacement parts not
equivalent to the original factory
equipment.
We recommend that you use caution when
your vehicle has either a high load or device
(such as ladders or luggage racks). Any
modifications to your vehicle that raise the
center of gravity may cause your vehicle
to roll over when there is a loss of vehicle
control.
Failure to maintain your vehicle correctly
may void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely
affect you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off road usage.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 388).
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop. See
Warning Lamps and
Indicators (page 114).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer. Brake Assist
Brake assist detects when you rapidly
brake by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. It can also reduce
stopping distances in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
If it illuminates when you are
driving, this indicates a
malfunction. Your vehicle
continues to have normal braking without
the anti-lock brake system function. Have
your vehicle checked as soon as possible.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer. It illuminates when you engage
the parking brake and the
ignition is on.
If it illuminates when your vehicle
is moving, make sure the parking
brake is disengaged. If the
parking brake is disengaged, this indicates
low brake fluid level or a brake system
fault. Have your vehicle checked as soon
as possible.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer.
