The front passenger sensing system is
designed to disable (will not inflate) the
front passenger frontal airbag when a rear
facing infant seat, a forward-facing child
restraint, or a booster seat is detected.
Even with this technology, parents are
strongly encouraged to always properly
restrain children in the rear seat. The
sensor also turns off the passenger front
airbag and seat-mounted side airbag when
the passenger seat is empty.
• When the front passenger sensing
system disables (will not inflate) the
front passenger frontal airbag, the
indicator lamp will illuminate and stay
lit to remind you that the front
passenger frontal airbag is disabled.
• If the child restraint has been installed
and the indicator lamp is not lit, then
turn the vehicle off, remove the child
restraint from the vehicle and reinstall
the restraint following the child
restraint manufacturer's instructions.
The front passenger sensing system is
designed to enable (may inflate) the front
passenger frontal airbag anytime the
system senses that a person of adult size
is sitting properly in the front passenger
seat. •
When the front passenger sensing
system enables the front passenger
frontal airbag (may inflate), the
indicator lamp will be unlit and stay
unlit.
If a person of adult size is sitting in the front
passenger seat, but the airbag off indicator
lamp is lit, it is possible that the person is
not sitting properly in the seat. If this
happens:
• Turn the vehicle off and ask the person
to place the seat back in the full upright
position.
• Have the person sit upright in the seat,
centered on the seat cushion, with the
person ’s legs comfortably extended.
• Restart the vehicle and have the person
remain in this position for about two
minutes. This will allow the system to
detect that person and enable the
passenger ’s frontal airbag.
• If the indicator lamp remains lit even
after this, the person should be advised
to ride in the rear seat. Passenger airbag

Note: When the front passenger airbag off
light is illuminated, the passenger (seat
mounted) side airbag may be disabled to
avoid the risk of airbag deployment injuries. After all occupants have adjusted their
seats and put on safety belts, it is very
important that they continue to sit
properly. A properly seated occupant sits
upright, leaning against the seat back, and
centered on the seat cushion, with their
feet comfortably extended on the floor.

DRIVER AND PASSENGER
KNEE AIRBAGS
WARNINGS
Keep the glove box door closed while
driving for optimal performance of
the passenger knee airbag during a
crash. To reduce risk of injury, do not
obstruct or place objects in the
deployment path of the knee airbag.
A driver knee airbag is located under or
within the instrument panel. A passenger
knee airbag is located within the glove box
door. During a crash, the restraints control
module may activate the driver and
passenger knee airbags based on crash
severity and occupant conditions. Under
certain crash and occupant conditions, the
driver and passenger knee airbag may
deploy but the driver front airbag may not
activate. As with front and side airbags, it
is important to be properly seated and
restrained to reduce the risk of death or
serious injury.
Make sure the knee airbags are
operating properly. See Crash
Sensors and Airbag Indicator
(page
43).
SAFETY CANOPY™ - COUPE WARNINGS
Do not place objects or mount
equipment on or near the headliner
at the siderail that may come into
contact with a deploying curtain airbag.
Failure to follow these instructions may
increase the risk of personal injury in the
event of a crash. Do not lean your head on the door.
The curtain airbag could injure you
as it deploys from the headliner. WARNINGS
Do not attempt to service, repair, or
modify the curtain airbags, its fuses,
the A, B, or C pillar trim, or the
headliner on a vehicle containing curtain
airbags as you could be seriously injured
or killed. Contact your authorized dealer
as soon as possible. All occupants of your vehicle
including the driver should always
wear their safety belts even when an
airbag supplemental restraint system and
curtain airbag is provided. Failure to
properly wear your safety belt could
seriously increase the risk of injury or death. To reduce risk of injury, do not
obstruct or place objects in the
deployment path of the curtain
airbag. If the curtain airbags have deployed,
the curtain airbags will not function
again. The curtain airbags (including
the A, B and C pillar trim and headliner)
must be inspected and serviced by an
authorized dealer. If the curtain airbag is
not replaced, the unrepaired area will
increase the risk of injury in a crash. The Safety Canopy will deploy during
significant side crashes or when a certain
likelihood of a rollover event is detected
by the rollover sensor. The Safety Canopy
is mounted to the roof side-rail sheet
metal, behind the headliner, above each
row of seats. In certain sideways crashes
or rollover events, the Safety Canopy will
be activated, regardless of which seats are
occupied. The Safety Canopy is designed
to inflate between the side window area
and occupants to further enhance
protection provided in side impact crashes
and rollover events.
42
Mustang (), enUSA, First Printing Supplementary Restraints System

The system consists of the following:
•
Safety canopy curtain airbags located
above the trim panels over the front
and rear side windows identified by a
label or wording on the headliner or
roof-pillar trim.
• A flexible headliner which opens above
the side doors to allow air curtain
deployment •
The crash sensors and monitoring
system have a readiness indicator. See
Crash Sensors and Airbag Indicator
(page 43).
Children 12 years old and under should
always be properly restrained in the rear
seats. The Safety Canopy will not interfere
with children restrained using a properly
installed child or booster seat because it
is designed to inflate downward from the
headliner above the doors along the side
window opening.
The design and development of the Safety
Canopy included recommended testing
procedures that were developed by a
group of automotive safety experts known
as the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of injuries
related to the deployment of side airbags
(including the Safety Canopy). CRASH SENSORS AND
AIRBAG INDICATOR WARNING
Modifying or adding equipment to
the front end of the vehicle (including
frame, bumper, front end body
structure and tow hooks) may affect the
performance of the airbag system,
increasing the risk of injury. Do not modify
the front end of the vehicle. Your vehicle has a collection of crash and
occupant sensors which provide
information to the restraints control
module. The restraints control module
deploys (activates) the front safety belt
pretensioners, driver airbag, passenger
airbag, knee airbag(s), seat mounted side
airbags and Safety Canopy airbags. Based
on the type of crash (frontal impact or side
impact), the restraints control module will
deploy the appropriate safety devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following:
The readiness light will not
illuminate immediately after the
ignition is turned on.
• The readiness light will either flash or
stay lit.
• A series of five beeps will be heard. The
tone pattern will repeat periodically
until the problem, the light or both are
repaired.

Mustang (), enUSA, First Printing Supplementary Restraints SystemE75004

If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The safety belt pretensioners and the front
airbag supplemental restraint system are
designed to activate when the vehicle
sustains frontal deceleration sufficient to
cause the restraints control module to
deploy a safety device.
The fact that the safety belt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
•
The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts) unless the crash causes
sufficient frontal deceleration.
• The safety belt pretensioners are
designed to activate in frontal,
near-frontal and side crashes.
• The knee airbag(s) may deploy based
on crash severity and occupant
conditions.
• The design of the side airbags is to
inflate in certain side crashes. The
design of the Safety Canopy is to
inflate in certain side impact crashes
and when a certain likelihood of
rollover is detected by the rollover
sensor. Side airbags and Safety Canopy
airbags may activate in other types of
crashes if the vehicle experiences
sufficient sideways motion or
deformation. AIRBAG DISPOSAL
Contact your authorized dealer as soon as
possible. Airbags must be disposed of by
qualified personnel.

PRINCIPLE OF OPERATION
MyKey allows you to program keys with
restricted driving modes to promote good
driving habits. All but one of the keys
programmed to the vehicle can be
activated with these restricted modes.
Any keys that have not been programmed
are referred to as administrator keys or
admin keys. These can be used to:
•
Create a MyKey.
• Program configurable MyKey settings.
• Clear all MyKey features.
When you have programmed a MyKey, you
can access the following information using
the information display:
• How many admin keys and MyKeys are
programmed to your vehicle.
• The total distance your vehicle has
traveled using a MyKey.
Note: All MyKeys are programmed to the
same settings. You cannot program them
individually.
Note: For vehicles with intelligent access
with push-button start, when both a MyKey
and an admin intelligent access key fob are
present, the admin fob will be recognized
by the vehicle while switching the ignition
on to start the vehicle.
Non-configurable Settings
The following settings cannot be changed
by an admin key user:
• Belt-Minder. You cannot disable this
feature. The audio system will mute
when the front seat occupants’ safety
belts are not fastened.
• Early low fuel. The low-fuel warning
activates earlier, giving the MyKey user
more time to refuel. •
Driver assist features, if equipped on
your vehicle, are forced on: parking aid,
blind spot information system (BLIS)
with cross traffic alert, lane departure
warning and forward collision warning
system.
• Track Mode, if your vehicle is equipped
with this feature, will be disabled.
Configurable Settings
With an admin key, you can configure
certain MyKey settings when you first
create a MyKey and before you recycle the
key or restart the vehicle. You can also
change the settings afterward with an
admin key.
• A vehicle speed limit can be set.
Warnings will be shown in the display
followed by an audible tone when your
vehicle reaches the set speed. You
cannot override the set speed by fully
depressing the accelerator pedal or by
setting cruise control.
• Vehicle speed minders of 45 mph
(75 km/h), 55 mph (90 km/h) or
65 mph (105 km/h). Once you select
a speed, it will be shown in the display,
followed by an audible tone when the
preselected vehicle speed is exceeded.
• Audio system maximum volume of
45%. A message will be shown in the
display when you attempt to exceed
the limited volume. Also, the
speed-sensitive or compensated
automatic volume control will be
disabled.
• Always on setting. When this is
selected, you will not be able to turn
off Advance Trac, Emergency Assist
and Do Not Disturb (if your vehicle is
equipped with these features), and
