2021 FORD F-450 display

The warning system is in two stages. At
first the system issues a temporary warning
that you need to take a rest. This message
only appears for a short time. If the system
detects further reduction in driving
alertness, another warning could be issued
which remains in the information display
for a longer time. Press OK on the steering
wheel control to clear the warning. When
active the system runs in the background
and only issues a warning if required.
Resetting the System
You can reset the system by either:
•
Switching the ignition off and on.
• Stopping the vehicle and then opening
and closing the driver door.
LANE KEEPING SYSTEM (IF
EQUIPPED) WARNING: You are responsible for
controlling your vehicle at all times. The

When you switch the system on and it
detects an unintentional drift out of your
lane is likely to occur, the system notifies
or assists you to stay in your lane through
the steering system and information
display. The system provides an audible
warning and by vibrating the steering
wheel.
Switching the System On and Off
Note:
The system on or off setting is stored
until it is manually changed, unless a MyKey
is detected. If the system detects a MyKey,
it defaults to on and the mode is set to alert.
Note: If a MyKey is detected, pressing the
button does not affect the on or off status
of the system. You can only change the
mode and intensity settings. Press the button to switch the
system on or off. The button is
above the audio unit or on the
center console.
System Settings
The system sensitivity and intensity can
be adjusted through the display screen.
See General Information (page 110). The
system remembers the last selection. You
do not need to readjust the setting each
time you turn on your vehicle.
Sensitivity: This setting allows you to
select where in the lane a warning is
provided. Increasing the sensitivity setting
moves the warning zones in closer to your
vehicle. Normal

Note:
The overhead vehicle graphic may
still display if adaptive cruise control is
enabled.
While the system is on, the color of the
lane markings change to indicate the
system status.
Gray: Indicates that the system is
temporarily unable to provide a warning
on the indicated side(s). This may be
because:
• Your vehicle is under the activation
speed.
• The direction indicator is active.
• Your vehicle is in a dynamic maneuver.
• The road has no or poor lane markings
in the camera field-of-view.
• The camera is obscured or unable to
detect the lane markings due to
environmental, traffic or vehicle
conditions. For example, significant sun
angles, shadows, snow, heavy rain or
fog, following a large vehicle that is
blocking or shadowing the lane or poor
headlamp illumination. See
Troubleshooting for additional
information.
Green
: Indicates that the system is
available or ready to provide a warning on
the indicated side(s).
Red
: Indicates that the system is providing
or has just provided a lane keeping alert
warning.
You can temporarily disable the system at
any time by doing the following:
• Quick braking.
• Fast acceleration.
• Using your direction indicator.
• Evasive steering maneuver.
• Driving too close to the lane markings.
Troubleshooting Why is the feature not available (line markings are gray) when I can see the lane markings
on the road?
Your vehicle speed is outside the operational range of the feature.
The sun is shining directly into the camera lens.
A quick intentional lane change has occurred.
Your vehicle stays too close to the lane markings.
Driving at high speeds in curves.
The last feature activation occurred a short time ago.
Ambiguous lane markings, for example in construction zones.
Rapid transition from light to dark, or from dark to light.
Sudden offset in lane markings.

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 283).
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.

System Operation
If you select a trailer in the display screen
prior to connecting the trailer, the system
will load that configuration and the
information cluster displays a message
when the trailer is connected. A second
message appears stating Cross Traffic
Alert has been turned off; the Blind Spot
Information System with Trailer Tow still
functions normally when driving forward.
If no trailer has been set up and a trailer is
connected, the instrument cluster provides
a message indicating a trailer is connected
followed by a message asking to select a
trailer from the existing list of trailers or to
add a trailer. In order for the Blind Spot
Information System with Trailer Tow to
function, an existing trailer must be
selected or a new trailer must be added. If
the request is ignored or if you exit the
screen, a message appears prompting you
that the system has been turned off due
to a trailer connect. This message may not
appear until your vehicle speed reaches
22 mph (35 km/h).
The Blind Spot Information System with
Trailer Tow activates when driving forward
for that particular trailer set up. If the
ignition is cycled, the Blind Spot
Information System with Trailer Tow
continues to function using the last trailer
selected.
Trailer Considerations
The Blind Spot Information System with
Trailer Tow is designed to work with any
trailer whose front width is
8.5 ft (2.6 m)
or less and total length from the trailer
hitch ball to the rear of the trailer is
33 ft
(10.1 m) or less. Different trailers may
cause a slight change in performance as
outlined below. Large box trailers may cause false alerts
to trigger when driving next to buildings or
near parking cars. A false alert may also
occur while making a 90-degree turn.
Trailers that are
8.5 ft (2.6 m) wide at the
front and have a total length greater than
20 ft (6 m)
may have delayed alerts from
passing vehicles when the vehicle is
passing at high speed.
A box trailer whose front width is
8.5 ft
(2.6 m) may cause early alerts when you
are over taking a vehicle.
When towing a clam shell or V-Nose box
trailer with a front width of
8.5 ft (2.6 m),
delayed alerts on merging vehicles that are
traveling the same speed as your vehicle
may occur.
System Errors
If the system senses a problem with the
left or right sensor, the telltale illuminates
and a message appears in the display
screen. See
Information Messages
(page 121).
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the display
screen. See
General Information (page
110). When the Blind Spot Information
System switches off, you do not receive
alerts and the display screen shows a
system off message. The telltale in the
cluster also illuminates. When you switch
the Blind Spot Information System on or
off, the alert indicators flash twice.
Note: The Blind Spot Information System
remembers the last selected on or off
setting.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer.

Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
Cross Traffic Alert System Sensors
The sensors are inside the brake lamp on
both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects. Note:
Blocked sensors could affect system
performance.
If the sensors are blocked, a message may
appear in the information display when
you shift into reverse (R).
Cross Traffic Alert System
Limitations
The system may not correctly operate
when any of the following occur:
• The sensors are blocked.
• Adjacently parked vehicles or objects
are obstructing the sensors.
• Vehicles approach at speeds less than
4 mph (6 km/h) or greater than 37 mph
(60 km/h).
• The vehicle speed is greater than 7 mph
(12 km/h)
.
• You reverse out of an angled parking
space.

Cross Traffic Alert Behavior When
Trailer is Attached
Note:
The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
Cross traffic alert remains on when you
attach a trailer in vehicles that come with
blind spot information system with trailer
tow under the following conditions:
• You connect a trailer.
• The trailer is a bike rack or cargo rack
with a maximum length of 3 ft (1 m).
• You set the trailer length to
3 ft (1 m)
in the information display.
See
Blind Spot Information System
(page 254).
Switching the System On and Off
To switch the system on or off, adjust the
setting. Depending on your vehicle options,
the setting could be in the following: •
Information display. See
General
Information (page 110).
• Touchscreen. See Settings (page 543).
Note: The system turns on every time you
switch the ignition on. To permanently
switch the system off, contact an authorized
dealer.
Cross Traffic Alert Indicator When the system detects an
approaching vehicle, a tone
sounds, a warning lamp
illuminates in the relevant exterior mirror
and arrows appear in the information
display to show which side the
approaching vehicle is coming from.
Note: If arrows do not display, a message
appears in the information display.
If the system malfunctions, a warning lamp
illuminates in the instrument cluster and
a message appears in the information
display. Have your vehicle checked as soon
as possible.
Note: In exceptional conditions, the system
could alert you, even when there is nothing
in the detection zone, for example a vehicle
passing further away from your vehicle.

STEERING
Hydraulic Power Steering
To help prevent damage to the power
steering system:
•
Do not hold the steering wheel at its
furthest turning points for more than
three to five seconds when the engine
is running.
• Avoid continuously steering back and
forth with elevated engine RPM as this
may overheat the system. If trying to
free a stuck vehicle, pause between
attempts to allow the power steering
system to cool or seek assistance.
Typical steering and driving maneuvers
allow the system to cool.
• Do not operate the vehicle if the power
steering pump fluid level is below the
MIN mark on the reservoir.
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
or if you switch the engine off, you can
steer the vehicle manually, but it takes
more effort.
If you have any steering components
serviced or replaced, install new fasteners.
Many fasteners have coatings with thread
adhesive, or have prevailing torque
features you cannot reuse. Do not reuse a
bolt or nut. Torque fasteners to
specifications. Steering Tips
If the steering wanders or pulls, check for:
•
An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped) WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
