warning light FORD SUPER DUTY 2017 4.G Workshop Manual

PRINCIPLE OF OPERATION
WARNINGS
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. Hill descent control does not provide
hill hold at zero miles per hour (0
kilometers per hour). When stopped,
the parking brake must be applied or the
vehicle must be placed in P (Park) or it
may roll away. 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 located on the
instrument panel. A light in the
cluster will illuminate and a chime will
sound 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 will be 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.
Hill descent modes
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and Hill Descent Control is
active, the Hill Descent Control telltale
will flash.
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and conditions are not
correct for hill descent activation, the
Hill Descent Control system will be
enabled, the Hill Descent Control
telltale will be solid and a message will
display in the information display.
• At speeds above 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed, the Hill Descent Control
system will be enabled, the telltale in
the cluster will not be illuminated and
a message will be displayed in the
information display.

Switching Cruise Control Off
Press and release OFF when the system is
in stand by mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off.
USING ADAPTIVE CRUISE
CONTROL
(If Equipped) WARNINGS
Always pay close attention to
changing road conditions when using
adaptive cruise control. The system
does not replace attentive driving. Failing
to pay attention to the road may result in
a crash, serious injury or death. Adaptive cruise control is not a crash
warning or avoidance system.
Adaptive cruise control does not
detect stationary or slow moving
vehicles below
6 mph (10 km/h).
Adaptive cruise control does not
detect pedestrians or objects in the
road.
Adaptive cruise control does not
detect oncoming vehicles in the
same lane.
Do not use adaptive cruise control
on winding roads, in heavy traffic or
when the road surface is slippery.
This could result in loss of vehicle control,
serious injury or death. Do not use adaptive cruise control
with a snow plow blade installed. WARNINGS
Do not use adaptive cruise control
when towing a trailer that has trailer
brakes. The auto-brake component
of the adaptive cruise control system does
not operate the trailer brakes. Using
adaptive cruise control when towing a
trailer that has trailer brakes may result in
the loss of vehicle control, which could
result in serious injury. Do not use tire sizes other than those
recommended because this can
affect the normal operation of the
system. Failure to do so may result in a loss
of vehicle control, which could result in
serious injury. Note:
It is your responsibility to stay alert,
drive safely and control the vehicle at all
times.
The system adjusts your speed to maintain
a proper distance between you and the
vehicle in front of you in the same lane. You
can select from one of four gap settings. The controls for using your cruise control
are located on the steering wheel.
Switching the System On
Press and release
ON.
The information display shows
the grey indicator light.

shows.
Setting a Speed
1. Accelerate to the desired speed.
2. Press and release
SET+. The memory
stores the vehicle speed.
3. The information display shows a green
indicator light, current gap setting and
the desired set speed.
4. Take your foot off the accelerator pedal. 5.
A lead vehicle graphic illuminates if the
system detects a vehicle in front of you.
Note: When adaptive cruise control is
active, the speedometer may vary slightly
from the set speed displayed in the
information display. Following a Vehicle WARNINGS
When following a vehicle, your
vehicle does not decelerate
automatically to a stop, nor does
your vehicle always decelerate quickly
enough to avoid a crash without driver
intervention. Always apply the brakes when
necessary. Failing to do so may result in a
crash, serious injury or death. Adaptive cruise control only warns
of vehicles detected by the radar
sensor. In some cases there may be
no warning or a delayed warning. Always
apply the brakes when necessary. Failure
to do so may result in a crash, serious injury
or death. Note:
The brakes may emit a sound when
the adaptive cruise control system is active.
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in
the same lane, the vehicle speed adjusts
to maintain a preset gap distance. The
distance setting is adjustable.
The lead vehicle graphic illuminates.
The vehicle maintains a constant distance
from the vehicle ahead until:
• The vehicle in front of you accelerates
to a speed above the set speed.
• The vehicle in front of you moves out
of your lane or out of view.
• The vehicle speed falls below
12 mph
(20 km/h).
• You set a new gap distance.
The system applies the brakes to slow the
vehicle to maintain a safe distance from
the vehicle in front. The system applies
only limited maximum braking. Press the
brake pedal to override the system.

If the system predicts that its maximum
braking level is insufficient, an audible
warning sounds while the system
continues to brake. A red warning bar
appears on the windshield heads-up
display. Take immediate action to slow or
stop the vehicle.
The system may provide slight temporary
acceleration when you use your driver side
directional indicator while following a lead
vehicle, to aid in passing the vehicle.
Setting the Gap Distance
Note:
It is your responsibility to select a gap
appropriate to the driving conditions. Gap decrease.
A
Gap increase.
B Press the gap control to decrease or
increase the distance between your vehicle
and the vehicle in front of you. Bars in the graphic show the selected gap
distance. You can select between four gap
settings.
Note:
When you select Tow/Haul Mode,
the gap distance is increased slightly.

Due to the nature of radar technology, it is
possible to get a blockage warning and not
have a blockage. This can happen, for
example, when driving in sparse rural or
desert environments. A false blocked
condition either self clears or clears after
a key cycle.
Switching to Normal Cruise
Control
WARNING
Normal cruise control will not brake
when your vehicle is approaching
slower vehicles. Always be aware of
which mode you have selected and apply
the brakes when necessary. You can manually change from adaptive
cruise control to normal cruise control
through the information display. See
Information Messages (page 128).
The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, the system does
not automatically respond to lead vehicles
and automatic braking remains active to
maintain set speed. The system recalls its
last setting when you start your vehicle.

BLIND SPOT INFORMATION
SYSTEM (If Equipped) WARNING
Never
use the Blind Spot
Information System as a
replacement for using the interior
and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. Note:
The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor detect parked vehicles,
people, animals or infrastructure (fences,
guardrails, trees). It is only designed to alert
you to moving vehicles in the blind spot
zones.
Note: When a vehicle passes quickly
through the blind spot zone, typically fewer
than two seconds, the system does not
trigger.

C
You can set-up any trailer to work with the
Blind Spot Information System with Trailer
Tow through the instrument cluster menu.
See General Information (page 111).
While setting up a trailer, a sequence of
screens appear asking for trailer
information. The Blind Spot Information
System with Trailer Tow specific screens
are described below:
• Select type of trailer screen -
Conventional, fifth wheel or gooseneck.
The Blind Spot Information System with
Trailer Tow only supports conventional
trailers. If fifth wheel or gooseneck is
selected, the system automatically turns
off.
• Do you want to set up BLIS with trailer
screen?
If no, the Blind Spot Information System
turns off.
If yes, the menu goes to the next screen.
• Is the width less than
9 ft (2.7 m) and
length less than 30 ft (9 m)?
If no, the Blind Spot Information System
turns off.
If yes, the menu goes to the next screen.
• Trailer width measurement: The width of the trailer is measured at the
front of the trailer. It is not measured at the
widest point of the trailer. The maximum
width at the front of the trailer that the
Blind Spot Information System with Trailer
Tow can support is
8.5 ft (2.6 m).
Note: You do not need to enter an exact
trailer width measurement; just measure
that it is
8.5 ft (2.6 m) or less.
• Trailer length measurement:
The trailer length is the distance between
the trailer hitch ball and the rear of the
trailer. The maximum length that the Blind
Spot Information System with Trailer Tow
can support is
30 ft (9 m).
• Enter length of trailer:
The default setting is
18 ft (5.5 m).
Toggling up or down using the menu
buttons will increase/decrease the
measurement by
3 ft (1 m). Select the
length so that the value is equal to or
within
3 ft (1 m) of the actual measured
length. For example, if the actual measured
length is
25 ft (7.6 m), then toggle the
length in the menu to 27 ft (8.2 m). When
the length has been entered, the Blind Spot
Information System with Trailer Tow setup
is saved.
If you do not set up a Blind Spot Trailer, a
warning appears in the instrument cluster
when a trailer is connected stating that the
system has been turned off due to a trailer
connect.
Note: If the trailer is actually a bike rack or
cargo rack with electrical lighting, then the
length will be
3 ft (1 m). Cross Traffic Alert
will remain on for trailers 3 ft (1 m) or less.
Note: Proper measurement and
measurement entry is required for Blind
Spot Information System with Trailer Tow
to function as designed.

COLLISION WARNING SYSTEM
(If Equipped)
Principle Of Operation (If Equipped)
WARNINGS
This system is an extra driving aid. It
does not replace your attention and
judgment, or the need to apply the
brakes. This system does NOT
automatically brake your vehicle. If you fail
to press the brake pedal when necessary,
you may collide with another vehicle. The collision warning system with
brake support cannot help prevent
all collisions. Do not rely on this
system to replace your judgment and the
need to maintain correct distance and
speed. Note:
The system does not detect, warn or
respond to potential collisions with vehicles
to the rear or sides of your vehicle.
Note: The collision warning system is active
at speeds above approximately
5 mph
(8 km/h).
Note: The collision warning system will be
unavailable if you disable the electronic
stability control. See
Using Stability
Control (page 227). The system alerts you of certain collision
risks. The system's sensor detects your
vehicle's rapid approach to other vehicles
traveling in the same direction as your
vehicle. When your vehicle rapidly approaches
another vehicle, a red warning light flashes
and a tone sounds.
The brake support system assists you in
reducing any collision speed by
pre-charging the brakes. If the risk of
collision continues to increases after the
audio-visual warning, the brake support
prepares the brake system for rapid
braking. The system does not
automatically activate the brakes, but if
the brake pedal is pressed even lightly, the
brakes apply full stopping power.
Using the Collision Warning System
WARNING
The collision warning system
’s brake
support reduces collision speed only
if you brake your vehicle before any
collision. As in any typical braking situation,
you must press your brake pedal. You can use your information display
control to adjust the collision warning
system's sensitivity or to turn the system
On or Off. Your vehicle will remember
these settings across key cycles. You may
change the collision warning system
sensitivity to any one of three possible
settings. See General Information (page
111
).

TOWING A TRAILER
WARNINGS
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Do not exceed the GVWR or
the GAWR specified on the
certification label. Note:
See Recommended
Towing Weights (page 277).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 310).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop and load
capacity. When both the
loaded vehicle and trailer are
connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
261).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

Super Duty (TFE) Canada/United States of America, enUSA, First Printing Towing

slowly turning the wheel until the trailer
is following your desired path and then
holding the wheel in that position. If
you would like to recalibrate the
system for straight backing, you can do
so with the following procedure.
•
Go into the trailer menu, select
trailer options, select change trailer
setting and then select the change
sticker option. Your saved
measurements will be displayed.
Do not change them but continue
to confirm measurements. Once
you confirm the measurements, the
system will then prompt you to
perform the calibration procedure.
Note: The system is designed to be used
with the same trailer connection every time
the trailer is chosen from the selection
menu. Using a different drawbar or a
different pin hole (on drawbars with more
than one) when connecting the drawbar to
your vehicle will affect the trailer
measurements. Take the measurements
again and update if required.
TRAILER SWAY CONTROL (If
Equipped) WARNING
Turning off trailer sway control
increases the risk of loss of vehicle
control, serious injury or death. Ford
does not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation. Note:
This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying. Note:
In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message
TRAILER SWAY REDUCE
SPEED appears in the information display.
The first thing to do is slow your vehicle
down, then pull safely to the side of the
road and check for proper tongue load and
trailer load distribution. See
Load
Carrying (page 261).
RECOMMENDED TOWING
WEIGHTS WARNING
You must use the heavy-duty
drawbar pin supplied with
your vehicle when using the
heavy-duty hitch. Failure to follow
this instruction could result in the
loss of control of your vehicle,
personal injury or death. Note:
Vehicles with a heavy-duty
hitch must use the drawbar pin
stamped 21,000 LBS. You can
obtain a replacement drawbar pin
at your Ford dealer.
Note: Make sure to take into
consideration trailer frontal area.
Do not exceed 60 feet 2
(5.6
meters 2
) trailer frontal area for
conventional trailers. Do not
exceed 75 feet 2
(6.9 meters 2
) trailer
frontal area for 5th wheel and
gooseneck trailers.
