air condition FORD F-450 2020 Owner's Guide

Note:
4x4 low mode is not intended for use
on dry pavement.
1. Bring the vehicle to a speed of 3 mph
(5 km/h) or less.
2. Place the transmission in neutral (N).
3. Move the 4WD control to the preferred
position.
The information display will display a
message indicating a 4X4 shift is in
progress. The information display will then
display the system mode selected. If any
of the above shift conditions are not met,
the shift will not occur and the information
display will display information guiding the
driver through the proper shifting
procedures.
If a message in the information display
shows a Shift Delayed Pull Forward
message, a transfer case gear tooth
blockage is present. To alleviate this
condition, place the transmission in a
forward gear, move the vehicle forward
approximately
5 ft (1.5 m), and shift the
transmission back to neutral to allow the
transfer case to complete the range shift.
Entering and Exiting Rock Crawl
Mode with Tremor Package
(If
Equipped) •
To enter rock crawl, your vehicle must
be in 4x4 low.
• Press the drive mode button on the
shifter column to bring up the
information display and select rock
crawl mode.
• With the switch in 4x4 low position,
press rock crawl mode again to
deactivate it. •
You can now perform a shift out of 4x4
low.
• Refer to Shifting to or from 4L (4x4
low) as described previously for proper
operation of 4x4 low in this procedure.
Operating 4WD Vehicles with
Spare or Mismatched Tires
On four-wheel drive vehicles, the size of
the spare tire can affect the 4X4 system.
If there is a significant difference between
the size of the spare tire and the remaining
tires, you may have limited four-wheel
drive functionality.
When driving with the full-size, dissimilar
spare wheel and tire assembly, we
recommend that you do not:
• Exceed
50 mph (80 km/h) with a 4WD
mode turned on.
• Turn on a 4WD mode unless the
vehicle is stationary.
• Use a 4WD mode on dry pavement.
When driving with the full-size, dissimilar
spare wheel and tire assembly, you may
have limited 4WD functionality, especially
when driving in a mechanically locked 4WD
mode. You may experience the following:
• Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked 4WD mode.
Use of a dissimilar spare wheel and tire
assembly may lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.

How Your Vehicle Differs from
Other Vehicles
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning. Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern.
Note: Your vehicle may come with a front
air dam that can become damaged (due to
reduced ground clearance) when taking your
vehicle off-road. This air dam can be taken
off by removing 15 bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road.
Power is supplied to all four wheels
through a transfer case. On four-wheel
drive vehicles, the transfer case allows you
to select 4WD when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.
Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power the
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.

Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Four-Wheel Drive
(If Equipped)

The system uses radar sensors that are
located inside the tail lamp on each side
of your vehicle. Any dirt, mud and snow in
front of the sensors or driving in heavy rain
can cause system degradation. Also, other
types of obstructions in front of the sensor
can cause system degradation. This is
referred to as a
‘blocked ’ condition.
Note: Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance.
If the system detects a degraded
performance condition, a message warning
appears in the display screen. The alert
indicators remain ON and the system no
longer provides any warnings. You can
clear the warning but the alert indicators
remain illuminated.
A "blocked" condition can be cleared in
two ways:
• After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON.
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System without the Blind Spot
Trailer Tow package and a trailer attached
will cause poor system performance. Blind Spot Information System
with Trailer Tow (If Equipped)
The Blind Spot Information System with
Trailer Tow is designed to aid you in
detecting vehicles that may have entered
the detection area zone (A). The detection
area is on both sides of your vehicle and
trailer, extending rearward from the
exterior mirrors to the end of your trailer.
When a trailer is attached and the
customer has set up a Blind Spot Trailer,
the Blind Spot Information System with
Trailer Tow becomes active when driving
forward above
6 mph (10 km/h). See
Trailer Reversing Aids (page 274).
The Blind Spot Information System with
Trailer Tow can be turned off in the
instrument cluster. If the Blind Spot
Information System is turned off, then the
Blind Spot Information System with Trailer
Tow automatically turns off.

Radar Troubleshooting (If Equipped)
Action
Cause
Clean the grille surface in front of the radaror remove the object causing the obstruc- tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that there is no obstruction.
The surface of the radar in the grille is clean
but the message remains in the display screen.
Pre-Collision Assist disables itself. The
system automatically reactivates a short
time after the weather conditions improve.
Heavy rain, spray, snow or fog is interfering
with the radar signals.
Pre-Collision Assist disables itself. The
system automatically reactivates a short
time after the weather conditions improve.
Swirling water or snow or ice on the surface
of the road may interfere with the radar signals.
Contact an authorized dealer to have theradar checked for proper coverage and operation.
Radar is out of alignment due to a front end
impact.
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the camera's field
of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor automatically recalibrates
successfully. DRIVE CONTROL (IF EQUIPPED)
Selectable Drive Modes
The system delivers a driving experience
through a suite of sophisticated electronic
vehicle systems. These systems optimize
steering, handling and powertrain
response. This provides a single location
to control multiple system's performance
settings.
Changing the drive mode automatically
changes the functionality of the following
systems:

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.
Information Display Warning Messages
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred.
However, your Ford warranty does not cover
this diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT
Displays in response to faults sensed by
the trailer brake controller, accompanied
by a single tone. If this message appears,
contact an authorized dealer as soon as
possible for diagnosis and repair. The
controller may still function, but with
degraded performance.
WIRING FAULT ON TRAILER
Displays when there is a short circuit on
the electric brake output wire.
If this message displays, with no trailer
connected, the problem is with your vehicle
wiring or trailer brake controller. Contact
an authorized dealer.
If the message only displays with a trailer
connected, the problem is with the trailer
wiring. Consult your trailer dealer for
assistance. This can be a short to ground
(such as a chaffed wire), short to voltage
(such as a pulled pin on trailer emergency
breakaway battery) or the trailer brakes
may be drawing too much current. Points to Remember
Note:
Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result.
• Adjust gain setting before using the
trailer brake controller.
• Adjust gain setting, using the procedure
above, whenever road, weather, trailer
or vehicle loading conditions change
from when the gain was initially set.
• Only use the manual control lever for
proper adjustment of the gain during
trailer setup. Misuse, such as
application during trailer sway, could
cause instability of trailer or tow
vehicle.
• Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of
the trailer wheels. Trailer wheels can
lock up on slippery surfaces, resulting
in reduced stability of trailer and tow
vehicle.
• The trailer brake controller is equipped
with a feature that reduces output at
vehicle speeds below 11 mph (18 km/h)
so trailer and vehicle braking is not jerky
or harsh. This feature is only active
when applying the brakes using your
vehicle's brake pedal, not the
controller.
• The controller interacts with the brake
control system and powertrain control
system of your vehicle to provide the
best performance on different road
conditions.

•
Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Your vehicle may be equipped with a
temporary or conventional spare tire. A
"temporary" spare tire is different in size
(diameter or width), tread-type
(All-Season or All Terrain) or is from a
different manufacturer than the road tires
on your vehicle. Consult information on the
tire label or Safety Compliance label for
limitations when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
you remove the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability. Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS
WARNING:
If your vehicle has a
steering wheel lock make sure the
ignition is in the accessory or on position
when being towed.
Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
• Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in neutral (N).
If you cannot move the transmission
into neutral (N), you may need to
override it. See
Transmission (page
201).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
See
Climate Control (page 139).

ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving. •
Drive a heavily loaded vehicle or tow a
trailer.
• Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
• Driving with the wheels out of
alignment.
Conditions
• Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12 –16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
OFF-ROAD DRIVING
(IF EQUIPPED)
Note: The following off-road driving
information applies to Tremor package
equipped vehicles only.
307
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Driving Hints

•
When negotiating low speed obstacles,
applying light brake pressure in
conjunction with the throttle will help
prevent the vehicle from lurching and
will allow you to negotiate the obstacle
in a more controlled manner. Using 4L
also assists with this.
• Use and equip supplemental safety
equipment.
• Please consult your local off-road
group for other helpful tips.
• Off-roading requires a high degree of
concentration. Even if your local law
does not prohibit alcohol use while
driving off-road, Ford strongly
recommends against drinking alcohol
if you plan to off-road.
Crossing Obstacles
• Review the path ahead before
attempting to cross any obstacles. It is
best if the obstacles are reviewed from
outside the vehicle so that there is a
good understanding of the terrains
condition both in front of and behind
the obstacles.
• Approach obstacles slowly and slowly
creep the vehicle over.
• If a large obstacle such as a rock
cannot be avoided, choose a path that
places the rock directly under the tire
rather than the undercarriage of the
vehicle. This helps prevent damage to
the vehicle.
• Ditches and washouts should be
crossed at a 45 degree angle, allowing
each wheel to independently cross the
obstacle. Hill Climbing 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.
• Always attempt to climb a steep hill
along the fall line of the slope and not
diagonally.
• If the vehicle is unable to make it up
the hill, DO NOT attempt to turn back
down the slope. Place the vehicle in
low range and slowly back down in
reverse.
• When descending a steep slope, select
low gear and engage trail control. Use
the throttle and brake pedals to control
your descent speed as described earlier
in this section using trail control. Note
that trail control is functional in reverse
and should be used in this situation.
After Off-Road Driving
It is important to complete a full vehicle
inspection after off-road driving. Some
items to check include:
• Make sure that tires are inflated to
proper tire pressure as indicated on the
tire placard.
• Check the wheels and undercarriage
for built up mud or debris which can
cause vehicle vibration.
• Make sure that the grille and radiator
are clear of any obstructions that may
affect cooling.
• Make sure that the brakes are in proper
working order and free of any mud,
stones and debris, which can become
trapped around the brake rotor,
backing plate and caliper.
• Check that the air filter is clean and dry.
• Inspect for torn or punctured boots on
ball joints, half shafts, steering gears.
