light FORD F-150 2020 Repair Manual

Operator Commanded Regeneration
with Automatic Regeneration Control
(If Equipped)
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system. You can switch off automatic
regeneration until better driving conditions
are available, for example steady high
speed driving. You can then switch
automatic regeneration back on to clean
the diesel particulate filter.
Switching Automatic Regeneration
Control On and Off
To switch operator commanded
regeneration on and off, use the
information display control on the steering
wheel. See Information Display Control
(page
91). Scroll to the exhaust cleaning
message, a check in the box indicates the
feature is enabled, and unchecked
indicates the feature is disabled.
How to Interrupt or Cancel Operator
Commanded Regeneration
If you need to cancel the operator
commanded regeneration, pressing the
brake, accelerator or switching the engine
off stops the procedure. Depending on the
amount of time you allowed the operator
commanded regeneration to operate, soot
may not have had sufficient time to be fully
eliminated, but the exhaust system and
exhaust gas may still be hot. If you shut
your vehicle off during operator
commanded regeneration, you may notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal. Filter Service and Maintenance
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be replaced
with a new or remanufactured part at
approximately 250,000 mi (400,000 km).
Actual mileage varies depending on engine
and vehicle operating conditions.
If filter service is required, the
engine control system warning
lamp illuminates in the
information display. If there are any issues with the
diesel particulate filter system,
the engine control system
warning lamp and a service
engine soon warning lamp
illuminate to inform you that
your vehicle requires service. Have your
vehicle checked as soon as possible.
Resonator and Tailpipe Assembly
Maintenance
Aftermarket devices or modifications to
the exhaust system may reduce the
effectiveness of the exhaust system as
well as cause damage to the exhaust
system or engine. This may also degrade
vehicle performance and could lead to
engine damage that may not be covered
by the vehicle Warranty.

braking and extends lower gear
operation to enhance performance for
uphill climbs, hilly terrain or
mountainous areas. This increases
engine RPM during engine braking.
• Provides additional lower gear
operation through the automatic
transmission shift strategy.
• Selects gears more quickly and at
higher engine speeds.
To deactivate the sport mode feature and
return to normal driving mode, press the
button on the gearshift lever again. The
SPORT or
S indicator light deactivates
when the system turns off. The sport mode
feature also deactivates when you power
down your vehicle. Automatic Transmission Adaptive
Learning
This feature increases durability and
provides consistent shift feel over the life
of your vehicle. A new vehicle or
transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation.
Understanding your SelectShift™
Automatic Transmission
Your vehicle is equipped with a SelectShift
Automatic transmission gearshift lever.
The SelectShift Automatic transmission
gives you the ability to change gears up or
down (without a clutch) as desired.
In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically makes
some downshifts if it has determined that
you have not downshifted in time.
Although SelectShift makes some
downshifts for you, it still allows you to
downshift at any time as long as
SelectShift determines that damage to
the engine from over-revving does not
occur.
SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit. It must be shifted manually by
pressing the
+ button.
Note: Engine damage may occur if you
maintain excessive engine revving without
shifting.
The SelectShift Automatic transmission
feature has two modes: PRS and M mode.

USING FOUR-WHEEL DRIVE
Note:
For important information regarding
safe operation of this type of vehicle, see
General Information in the Wheels and Tires
chapter.
Note: Do not use 4H or 4L mode on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive components. 4H or 4L mode
is only intended for consistently slippery or
loose surfaces. Use of 4L mode on these
surfaces may produce some noise (such as
occasional clunks), but should not damage
drive components.
Note: If 4L is selected while your vehicle is
moving above 3 mph (5 km/h), the 4WD
system should not perform a shift. This is
normal and should be no reason for concern.
Refer to Shifting to or from 4L (4X4 Low)
for proper operation.
Note: You can switch on and switch off the
electronic locking differential by pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles). See
Electronic Locking
Differential (page 231).
4WD Indicator Lights
Note: When a 4X4 system fault is present,
the system can typically remain in whichever
4X4 mode was selected prior to the fault
condition occurring. It should not default to
4X2 in all circumstances. When this warning
is displayed, have your vehicle serviced by
an authorized dealer.
4X2 Momentarily illuminates when
2H is selected. 4X4 Auto Continuously illuminates when
4A is selected (2-Speed
Automatic 4WD vehicles only).
4X4 HIGH Continuously illuminates when
4H is selected.
4X4 LOW Continuously illuminates when
4L is selected.
CHECK 4X4 Displays when a 4X4 fault is
present.

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.

For 2WD vehicles
Turn the control to ON.
Once the indicator light
illuminates in the information
display, both rear wheel axle
shafts will be locked together providing
added traction.
If the indicator does not come on, or the
indicator turns off while driving, one of the
following has occurred:
• The vehicle speed is too high.
• The left and right rear wheel speed
difference is too high during an
engagement attempt.
• The system has malfunctioned and is
accompanied by a message in the
information display. See your
authorized Ford dealer for assistance.
• The vehicle is experiencing an anti-lock
brake activation.
Operating Electronic Locking
Differential With a Spare or
Mismatched Tires
On vehicles with an electronic locking
differential, the size of the spare tire can
affect performance of the system. If there
is a significant difference between the two
rear tires, you may have limited electronic
locking differential functionality. If the
electronic locking differential has difficulty disengaging, release the accelerator pedal
and turn the steering wheel in the opposite
direction when rolling. We recommend
engaging and disengaging the electronic
locking differential at a stop when you
mount a spare on the rear axle.

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.
