transmission FORD F-350 2021 Service Manual

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 207).
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake 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 could 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.

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

PRINCIPLE OF OPERATION
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as
ice or extremely steep grades. Hill
descent control is a driver assist system
and cannot substitute for good judgment
by the driver. Failure to do so may result
in loss of vehicle control, crash or serious
injury. WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission.
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h)
and 12 mph (20 km/h). Above
20 mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system will provide
a warning in the message center and a
chime will sound when the system is about
to disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button on the
instrument panel. A light in the
cluster illuminates and a tone sounds
when this feature is activated.
To increase descent speed, press the
accelerator pedal until the desired speed
is reached. To decrease descent speed,
press the brake pedal until the desired
speed is reached.
Whether accelerating or decelerating, once
the desired descent speed is reached,
remove your feet from the pedals and the
chosen vehicle speed is maintained.
Note: Noise from the ABS pump motor may
be observed during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system.This
may cause reduced performance or false
alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground.
Note: Certain add-on devices installed
around the bumper or fascia may create
false beeps. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system.
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. See your
authorized technician. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings.
Note: The sensing system cannot be turned
off when a MyKey is present. See
Information Messages
(page 121).
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level.
The sensing system can be switched off
through the information display menu or
from the pop-up message that appears
once you shift the transmission into reverse
(R). See General Information (page 110
).
If a fault is present in the system, a warning
message appears in the information
display and you cannot switch the system
on through the pop-up message. See
Information Messages
(page 121).
REAR PARKING AID
(IF EQUIPPED)
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
11.81 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
11.81 in (30 cm)
from the corners of the
bumper, the tone sounds for only two
seconds. Once the system detects an
object approaching, the warning sounds
again.
234
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Parking Aids

The coverage area is up to 6 ft (1.8 m) from
the rear bumper. The coverage area could
decrease at the outer corners of the
bumper.
The system detects certain objects while
the transmission is in reverse (R):
•
Your vehicle is moving toward a
stationary object at a speed of 3 mph
(5 km/h) or less.
• Your vehicle is not moving, but a
moving object is approaching the rear
of your vehicle at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is moving at a speed of
less than 3 mph (5 km/h) and a moving
object is approaching the rear of your
vehicle at a speed of less than
3 mph
(5 km/h).
The system provides audio warnings only
when your vehicle is moving or when your
vehicle is stationary, and the detected
obstacle is less than
12 in (30 cm) away
from the bumper.
Obstacle Distance Indicator
The system provides obstacle distance
indication through the display screen. See
Rear View Camera
(page 235). REAR VIEW CAMERA (IF EQUIPPED) WARNING:
The rear view camera
system is a reverse aid supplement
device that still requires the driver to use
it in conjunction with the interior and
exterior mirrors for maximum coverage. WARNING:
Objects that are close
to either corner of the bumper or under
the bumper, might not be seen on the
screen due to the limited coverage of the
camera system. WARNING:
Reverse your vehicle
as slow as possible, higher speeds may
limit your reaction time to stop your
vehicle. WARNING:
Use caution when the
tailgate is ajar. If the tailgate is ajar, the
camera will be out of position and the
video image may be incorrect. All
guidelines disappear when the tailgate
is ajar. Some vehicles may not come
equipped with guidelines. WARNING:
Use caution when
turning camera features on or off when
the transmission is not in park (P). Make
sure your vehicle is not moving.
The rear view camera system displays
what is behind your vehicle when you shift

The rear view camera is located on the
tailgate.
Using the Rear View Camera
System
The system uses three types of guides to
help you see what is behind your vehicle:
•
Active guidelines: Show the intended
path of your vehicle when reversing.
• Fixed guidelines: Show the actual path
your vehicle is moving while reversing
in a straight line. This can be helpful
when backing into a parking space or
aligning your vehicle with another
object behind you.
• Centerline: Helps align the center of
your vehicle with an object (for
example, a trailer).
Note: If the transmission is in reverse (R)
and the tailgate is ajar, no rear view camera
features are displayed.
Note: If the image does not turn off while
the transmission is not in reverse (R) and
you are driving over a speed of 5 mph
(8 km/h), have the system inspected by an
authorized dealer. Note:
When towing, the camera only sees
what is being towed behind your vehicle.
This might not provide adequate coverage
as it usually provides in normal operation
and some objects might not be seen. In
some vehicles, the guidelines may disappear
once the trailer tow connector is engaged.
The camera may not operate correctly
under the following conditions:
• Nighttime or dark areas if the reverse
lamps are not operating.
• Mud, water or debris obstructs the
camera's view. Clean the lens with a
soft, lint-free cloth and non-abrasive
cleaner.
• The camera is misaligned due to
damage to the rear of your vehicle.
