2021 FORD MUSTANG Owners Manual

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active.
Switching the System Off When you switch the system off,
a message and an illuminated
icon appear on the instrument
cluster. Use the switch again to return the traction
control system to normal operation.
The switch for the stability and traction
control system is on the instrument panel.
Your vehicle may have MyKey restrictions
regarding this feature. See
What Is
MyKey (page 63).
System Indicator Lights and
Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin.
See
Using Traction Control (page 174).

The sensors are on the rear bumper.
The sensors are active when the
transmission is in reverse (R) and the
vehicle speed is less than 3 mph (5 km/h).
When the parking aid system sounds a
tone, the audio system may reduce the set
volume. A warning tone sounds when your vehicle
approaches an object. As your vehicle
moves closer to an object, the rate of the
tone increases. The warning tone
continuously sounds when an object is 12 in
(30 cm)
or less from the center of the rear
bumper.
Note: There is a decreased coverage area
at the outer corners. The sensor coverage area is up to
70 in
(180 cm) from the rear bumper.
If the system detects a fault, a warning
message appears in the information
display.
The system detects large objects when
you shift into reverse (R) and any of the
following occur:
• Your vehicle is moving backward at low
speed.
• Your vehicle is stationary but an object
is approaching the rear of your vehicle
at low speed.
• Your vehicle is moving backward at low
speed and an object is moving toward
your vehicle, for example another
vehicle at low speed.
179
Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-09-2020, enUSA, Edition date: 202010, Second-Printing Parking AidsE130178

If your vehicle remains stationary for two
seconds the audible warning turns off. If
your vehicle moves backward the tone
sounds again.
Note:
If the detected object is 12 in (30 cm)
or less from the rear bumper, the audible
warning does not turn off.
Object Distance Indicator (If Equipped) The system provides object distance
indication through the information display.
•
As the distance to the object
decreases, the indicator blocks
illuminate and move toward the vehicle
icon.
• If the system does not detect an object,
the distance indicator blocks are gray.
When you shift into reverse (R), the system
provides audible warnings and visual
indication when your vehicle is moving and
the detected object is moving toward your
vehicle. When you stop your vehicle, the
audible warnings stop after two seconds.
Visual indication remains on when the
transmission is in reverse (R). REAR VIEW CAMERA WARNING: The rear view camera
system is a reverse aid supplement
device that still requires the driver to use
it in conjunction with the interior and
exterior mirrors for maximum coverage. WARNING:
Objects that are close
to either corner of the bumper or under
the bumper, might not be seen on the
screen due to the limited coverage of the
camera system. WARNING:
Reverse your vehicle
as slow as possible, higher speeds may
limit your reaction time to stop your
vehicle. WARNING:
Use caution when the
rear cargo door is ajar. If the rear cargo
door is ajar, the camera will be out of
position and the video image may be
incorrect. All guidelines disappear when
the rear cargo door is ajar. Some vehicles
may not come equipped with guidelines. WARNING:
Do not switch the
camera features on or off when your
vehicle is moving.
The rear view camera system provides a
video image of the area behind your

The camera is located on the rear cargo
door.
Using the Rear View Camera
System
The rear view camera system displays
what is behind your vehicle when you place
the transmission in reverse (R).
Note:
The reverse sensing system is not
effective at speeds above 3 mph (5 km/h)
and may not detect certain angular or
moving objects.
The system uses two types of guides to
help you see what is behind your vehicle:
• Fixed guidelines: Show the actual path
your vehicle is moving in while reversing
in a straight line. This can be helpful
when backing into a parking space or
aligning your vehicle with another
object behind you.
• Centerline: Helps align the center of
your vehicle with an object.
Note: If the transmission is in reverse (R)
and the luggage compartment is open, no
camera features will display. The camera may not operate correctly
under the following conditions:
•
Nighttime or dark areas if the reverse
lamps are not operating.
• Mud, water or debris obstructs the
camera's view. Clean the lens with a
soft, lint-free cloth and non-abrasive
cleaner.
• The camera is misaligned due to
damage to the rear of your vehicle.
Camera Guidelines
Note: Active guidelines are only available
when the transmission is in reverse (R).
Note: Upon a battery disconnect, the active
guidelines may not be functional until your
vehicle has been driven a short distance and
exceeds a speed of
12 mph (20 km/h).
