ignition FORD F-150 2021 Repair Manual

Side Wind Stabilization
Side wind stabilization is an advanced
feature that works by carefully applying
the brakes on one side of the vehicle to
reduce the effect of a side wind gust on
the vehicle's path.
Torque Vectoring by Brakes
Torque vectoring control applies brake
torque on the inner driven wheel in a curve
for better traction to avoid an understeer,
or oversteer situation. Unlike electronic
stability control, enhanced torque
vectoring control does not slow the
vehicle. It helps control excessive wheel
slip and gives the vehicle improved
cornering agility.
Traction Control
Traction control enhances your vehicle
’s
ability to maintain traction of the wheels
by detecting and controlling wheel spin.
See What Is Traction Control (page 319). Vehicle without stability control

SWITCHING STABILITY
CONTROL ON AND OFF
Stability Control turns on each time you
switch the ignition on.
You can switch the stability control off by
pressing and holding the stability and
traction control button off for 5-15
seconds, or you can press the button again
to switch the system on.
Shifting the transmission into reverse (R)
will disable the system.
You can switch the traction control system
off or on independently. See Switching
Traction Control On and Off (page 319).

WHAT IS CRUISE CONTROL
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal.
Requirements
Use cruise control when the vehicle speed
is greater than 15 mph in imperial units and
20 km/h in metric units.
SWITCHING CRUISE CONTROL
ON AND OFF
WARNING: 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.
The cruise controls are on the steering
wheel.
Switching Cruise Control On Press the button to activate the
system. When the system
activates, the set speed is equal
to whichever is greater, the current vehicle
speed, or 15 mph when in imperial units or
20 km/h when in metric units. If the speed
is too low, or other conditions are not
correct for cruise control activation, the
system will instead enter standby mode.
Switching Cruise Control Off Press the button when the
system is active or switch the
ignition off.
Note: When you switch cruise control off,
the set speed clears. SETTING THE CRUISE
CONTROL SPEED WARNING:
When you are going
downhill, your vehicle speed could
increase above the set speed. The
system does not apply the brakes.
Drive to the speed you prefer. Press either the SET+ or SET-
buttons to set the current speed.
Take your foot off the accelerator pedal.
Note: The indicator changes color in the
information display.
Changing the Set Speed Press the SET+ button to
increase the set speed in small
increments. Press and hold the
SET+ button to accelerate. Release the
button when you have reached your
preferred speed. Press the SET- button to
decrease the set speed in small
increments. Press and hold the
SET- button to decelerate. Release the
button when you have reached your
preferred speed.
Note: If you accelerate by pressing the
accelerator pedal, the set speed does not
change. When you release the accelerator
pedal, your vehicle returns to the speed that
you previously set.

Cross Traffic Alert Limitations
with a Trailer Attached
The system remains on when you attach
a trailer in vehicles 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 instrument cluster display.
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.
SWITCHING CROSS TRAFFIC
ALERT ON AND OFF
To switch cross traffic alert on or off use
the touchscreen.
1. Press
Features on the touchscreen.
2. Press
Driver Assistance.
3. Switch
Cross Traffic Alert on or off.
Note: The system switches on every time
you switch the ignition on. To permanently
switch the system off, contact an authorized
dealer. LOCATING THE CROSS
TRAFFIC ALERT 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 may affect system
accuracy.
If something is blocking the sensors, a
message may appear in the information
display when you shift into reverse (R).
Note: Bike and cargo racks could cause
false alerts due to obstruction of the sensor.
We recommend switching the feature off
when using a bike or cargo rack.
CROSS TRAFFIC ALERT
INDICATORS When the cross traffic alert
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 vehicle is
approaching from.

Pedestrian Detection Limitations
Pedestrian detection is active at speeds
up to 50 mph (80 km/h).
Pedestrian detection operates optimally
when detected hazards are clearly
identifiable. System performance may
reduce in situations where pedestrians are
running, partly obscured, have a complex
background, or when the system cannot
distinguish pedestrians from a group.
Intersection Assist
(If Equipped)
If your vehicle comes with a radar sensor
included in adaptive cruise control, the
pre-collision assist system may operate in
a scenario where you are turning across an
oncoming vehicle's path. Detection of
vehicles driving in an oncoming direction
is active if your vehicle is driving at speeds
up to
19 mph (30 km/h). SWITCHING PRE-COLLISION

Note: If your vehicle has a radar sensor, we
recommend that you switch the system off
if you install a snow plow or similar object
in such a way that it may block the radar
sensor. Your vehicle remembers the selected
setting across key cycles.
Note: If you switch automatic emergency
braking off, evasive steering assist switches
off.
LOCATING THE PRE-
COLLISION ASSIST SENSORS
- POLICE RESPONDER Camera.
1 If a message regarding a blocked camera
appears in the instrument cluster display,
something is obstructing the camera
images. With a blocked camera, the
system may not function, or performance
may reduce. See Pre-Collision Assist –
Information Messages (page 404).
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor recalibrates successfully.

EVASIVE STEERING ASSIST
(IF
EQUIPPED)
WHAT IS EVASIVE STEERING
ASSIST
If your vehicle is rapidly approaching a road
user, evasive steering assist helps you steer
around the road user.
After you turn the steering wheel in an
attempt to avoid a crash with the road
user, the system applies additional steering
torque to help you steer around the road
user. After you pass the road user, the
system applies steering torque when you
turn the steering wheel to steer back into
the lane. The system deactivates after you
fully pass the road user.
Note: Road users are defined as another
stationary vehicle in the same lane or a
vehicle traveling in the same lane in the
same direction as you. See
Pre-Collision
Assist Precautions (page 396). EVASIVE STEERING ASSIST
LIMITATIONS
Evasive steering assist only activates when
all the following occur:
•
Automatic emergency braking and
evasive steering assist are on.
• The system detects a road user ahead
and starts to apply the brakes.
• You significantly turn the steering
wheel to steer around a road user.
Note: Evasive steering assist does not
automatically steer around a road user. If
you do not turn the steering wheel, evasive
steering assist does not activate.
Note: Evasive steering assist does not
activate if the distance to the road user
ahead is too small and the system cannot
avoid a crash.
Note: Evasive steering does not activate
with cyclists or pedestrians.
