HILL START ASSIST
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system turns off if
there is a malfunction or if you
excessively rev the engine.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system activates, your vehicle
remains stationary on a slope for a few
seconds after you release the brake pedal.
This allows you time to move your foot
from the brake to the accelerator pedal.
The brakes release when the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note: There is no warning lamp to indicate
the system is either on or off. Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.
2. The system activates if the sensors detect that your vehicle is on a slope.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for a few
seconds. This hold time increases if you
are in the process of driving off.
4. Pull away in the normal manner.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.
Vehicles with Automatic Transmission
The system turns on when you switch the
ignition on and you cannot switch the
system off.

Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-09-2020, enUSA, Edition date: 202010, Second-Printing Brakes

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:
• When a driving condition activates
either of the systems.
• If a problem occurs in either of the
systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on:
• When you switch the traction control
system off.
• When you select an alternative stability
control mode.

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).

to follow this instruction could result in
personal injury or death. WARNING:
The system only warns
of vehicles detected by the radar sensor.
In some cases there may be no warning
or a delayed warning. Apply the brakes
when necessary. Failure to follow this
instruction could result in personal injury
or death.
Note: When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small
temporary acceleration to help you pass.
Note: The brakes may emit noise when
applied by the system.
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. A
vehicle graphic illuminates in the
instrument cluster.

appears in the information display.
Automatic braking releases.
The system does not operate below
12 mph (20 km/h)
.
Hilly Condition Usage
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
Select a lower gear when the system is
active in situations such as prolonged
downhill driving on steep grades, for
example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle ’s regular brake system to prevent
it from overheating.

A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.
Possible Causes and Actions for This Message Displaying: Action
Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar is dirty or
obstructed.
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.
The surface of the radar is clean but the
message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow is interfering with the
radar signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Water, snow or ice on the surface of the
road may interfere with the radar signals.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. This happens, for example, when driving in sparse rural or desert
environments. A false blocked condition either self clears, or clears after you restart your
vehicle.
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 change from adaptive cruise
