Ford Super Duty (2017 year). Manual — part 59

PRINCIPLE OF OPERATION

Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).

USING CRUISE CONTROL

WARNINGS

Do not use 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.

When you are going downhill, your
vehicle speed may increase above
the set speed. The system will not

apply the brakes but a warning displays.
Failure to follow this warning could result
in serious personal injury or death.

Note: Cruise control will disengage if the
vehicle speed decreases more than 10 mph
(16 km/h) below the set speed while driving
uphill.

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.

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.

241

(If Equipped)

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.

E183739

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.

E233874

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.
