2020 FORD F-550 ignition

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.

Automatic Transmission Adaptive
Learning
This feature's design is to increase
durability and provide 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. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.
For F350, F450, F550 and F600
Chassis Cab Vehicles
Your transmission could reduce the load
on the engine when the vehicle stops, and
the gear selector is in drive (D) to reduce
fuel consumption and emissions. The
transmission resumes operation when you
release the brake. This feature activates
when the transmission is sufficiently
warmed, and the vehicle is on a level slope.
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.
Note: Do not drive your vehicle until you
verify that the brake lamps are working.
Your vehicle comes with brake-shift
interlock that prevents the gearshift lever
from moving from park (P) when you
switch the ignition on but have not pressed
the brake pedal.
If you cannot move the gearshift lever out
of the park (P) position when the ignition
is on and the brake pedal pressed, a
malfunction could 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 329).
If you do not have a blown fuse and the
brake lamps are working properly, the
following procedure allows you to move
the gearshift lever from park (P):
1. Apply the parking brake. Switch the ignition key to 1 - 0, then remove the
key.
See Starting and Stopping the
Engine (page 168).
2. Move the steering column to the full down and full rearward position,
toward the driver seat.
3. Remove the gearshift lever boot.

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, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved 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.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down
a hill or steep incline, you should always
try to drive straight up or straight down.
Note: Avoid turning on steep slopes or
hills. A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you will use. 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.
When climbing a steep slope or hill, start
in a lower gear rather than downshifting to
a lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling. If your vehicle stalls, do not try to turn
around because this could cause vehicle
roll over. It is better to reverse back to a
safe location.
Apply just enough power to the wheels to
climb the hill. Too much power will cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating.
Do not descend in neutral. Disengage
overdrive or move the transmission
selector lever to a lower gear. When
descending a steep hill, avoid sudden hard
braking as you could lose control. The front
wheels have to be turning in order to steer
your vehicle.
If your vehicle has anti-lock brakes, apply
the brakes steadily. Do not pump the
brakes.
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
212

(If Equipped)E143949

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.
Note: Excessive tire slippage can cause
transmission damage.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it will not 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 219).
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,
it may be rocked 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 are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if
the automatic transmission is in park (P)
or the manual transmission is in gear. Do
not leave the vehicle unattended with the
transfer case in the neutral (N) position.
Always set the parking brake fully and turn
off the ignition when leaving the vehicle.

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.
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. Shift 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 brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can 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. This lamp momentarily
illuminates when you switch the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective.
See Warning Lamps and Indicators
(page 104).
Note: Indicators vary depending on region. If the lamp remains illuminated
after you release the parking
brake, have the system checked
by an authorized dealer.
It also illuminates momentarily
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.
Diesel Engine Exhaust Braking
(If
Equipped) WARNING:
Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. WARNING:
Do not use diesel
engine exhaust braking when the road
surface is slippery. Failure to follow this
instruction could result in the loss of
control of your vehicle.
217
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Brakes E270480

You can use this feature with tow/haul or
progressive range selection to provide
further increased engine braking. The
transmission automatically upshifts to
prevent the engine from entering the red
zone on the tachometer. See Automatic
Transmission (page 201).
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
PARKING BRAKE WARNING:
Always set the parking
brake fully and make sure the
transmission is placed in park (P). Failure
to set the parking brake and engage park
could result in vehicle roll-away, property
damage or bodily injury. Turn the ignition
to the lock position and remove the key
whenever you leave your vehicle.
Apply the parking brake whenever your
vehicle is parked. Press the pedal
downward to set the parking brake. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released. To release, pull the brake release lever
located at the lower left side of the
instrument panel.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and
hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST
WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system will turn
off if a malfunction is apparent or if you
rev the engine excessively. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
219
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Brakes

When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note:
There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.
2. If the sensors detect that your vehicle is on a slope, the system activates
automatically.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The system releases the brakes
automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal. Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.
Vehicles with Automatic Transmission
You cannot turn the system on or off.
When you switch the ignition on, the
system automatically turns on.
