FORD F-150 2021 Owners Manual

Following a Vehicle
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 the gap setting.
Note:
When you are following a vehicle and
you switch on a turn signal lamp, adaptive
cruise control may provide a small,
temporary acceleration to help you pass.
Your vehicle maintains a consistent gap
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 the lane you are in.
• You set a new gap distance.
The system applies the brakes to slow
down your vehicle to maintain a safe gap
distance from the vehicle in front of you.
The system only applies limited braking.
You can override the system by applying
the brakes.
Note: The brakes may emit noise when
applied by the system.
If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds, a message appears in the
information display and an indicator
flashes when the system continues to
brake. Take immediate action.
CANCELING THE SET SPEED Press the button or tap the brake
pedal.
The set speed does not erase. RESUMING THE SET SPEED Press the button.
Your vehicle speed returns to the
previously set speed and gap setting. The
set speed displays continuously in the
information display when the system is
active.
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Resuming the Set Speed from a
Complete Stop (If Equipped)
If your vehicle follows a vehicle to a
complete stop and remains stationary for
less than a few seconds, your vehicle
accelerates from a stationary position to
follow the vehicle ahead.
If your vehicle follows a vehicle to a
complete stop and remains stationary for
more than a few seconds, an indicator and
message displays. 357

LANE CENTERING
HOW DOES LANE CENTERING
WORK
Adaptive cruise control with lane centering
uses radar and camera sensors to help
keep your vehicle in the middle of the lane
by applying continuous assistance steering
torque input toward the lane center on
highways.
Note: The adaptive cruise control gap
setting operates normally.
If you drive off-center within the lane, the
system sets and maintains that preferred
lane position. The system provides
continuous assistance steering torque
input toward the preferred position.
Note: The system can only set preferred
lane positions within the lane.
Note: If the system cancels, the preferred
position erases. On the next activation, the
system provides continuous assistance
steering torque input toward the lane center. LANE CENTERING PRECAUTIONS WARNING: Do not use the system
when towing a trailer. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Do not use the system
if any changes or modifications to the
steering wheel have been made. Any
changes or modifications to the steering
wheel could affect the functionality or
performance of the system. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.
Adaptive cruise control precautions apply
to lane centering unless stated otherwise
or contradicted by a lane centering
precaution. See Adaptive Cruise Control
Precautions
(page 352).

CRUISE CONTROL (IF EQUIPPED)
HOW DOES INTELLIGENT
ADAPTIVE CRUISE CONTROL
WORK
Intelligent adaptive cruise control
combines speed sign recognition with
adaptive cruise control to adjust the cruise
set speed to the speed limit detected by
the speed sign recognition system. As the
system detects new speed signs, the set
speed updates.
There are limitations that affect the
accuracy of the speed sign recognition
system and its ability to determine the
current speed limit. The intelligent
adaptive cruise control system and its
ability to determine the current speed limit
shares these limitations. See Speed Sign
Recognition
(page 409).
Note: The adaptive cruise control gap
setting operates normally.
INTELLIGENT ADAPTIVE CRUISE

WHAT IS BLUECRUISE
BlueCruise keeps your vehicle centered in
the lane and offers a hands-free driving
mode in certain situations when using
adaptive cruise control.
HOW DOES BLUECRUISE
WORK
BlueCruise uses cameras to monitor your
vehicle position within a lane and applies
steering support to keep your vehicle
centered in the lane.
Using the cameras and location
information, BlueCruise allows you to
remove your hands from the steering wheel
and offers a hands-free driving mode in
certain areas.
When active, BlueCruise uses a driver
facing camera and infrared lighting to
monitor your eyes and head position to
detect if you are distracted. If the system
determines you are distracted, it alerts you
to return your eyes to the road.
