Thanks to a popular mix of appearance,
features and power, the 1969-73 Mach 1's
proved to be everyman's muscle car, and
have earned a respected place in Mustang
performance lore. Beyond those classic
years, the Mach 1 carried over for all five
years of the often overlooked 1974-78's
before a hiatus that ended with the
modern and muscular 2003-04's. Mach
1’
s return to the Mustang lineup for 2021
will add a new chapter on modern-day
muscle for this beloved model, and will
cement its rightful place near the very top
of Mustang performance history.

reprogramming services. Installing an
aftermarket device that uses the DLC
during normal driving for purposes such as
remote insurance company monitoring,
transmission of vehicle data to other
devices or entities, or altering the
performance of the vehicle, may cause
interference with or even damage to
vehicle systems. We do not recommend
or endorse the use of aftermarket plug-in
devices unless approved by Ford. The
vehicle Warranty will not cover damage
caused by an aftermarket plug-in device.
MOBILE COMMUNICATIONS
EQUIPMENT WARNING:
Driving while
distracted can result in loss of vehicle
control, crash and injury. We strongly
recommend that you use extreme
caution when using any device that may
take your focus off the road. Your
primary responsibility is the safe

hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving.
Using mobile communications equipment
is becoming increasingly important in the
conduct of business and personal affairs.
However, you must not compromise your
own or others’ safety when using such
equipment. Mobile communications can
enhance personal safety and security when
appropriately used, particularly in
emergency situations. Safety must be
paramount when using mobile
communications equipment to avoid
negating these benefits. Mobile
communication equipment includes, but
is not limited to, cellular phones, pagers,
portable email devices, text messaging
devices and portable two-way radios.

GENERAL INFORMATION
See the following sections for directions
on how to properly use safety restraints
for children.
WARNING: Always make sure your
child is secured properly in a device that
is appropriate for their height, age and
weight. Child safety restraints must be
bought separately from your vehicle.
Failure to follow these instructions and
guidelines may result in an increased risk
of serious injury or death to your child. WARNING: All children are shaped
differently. The National Highway Traffic
Safety Administration and other safety
organizations, base their
recommendations for child restraints on
probable child height, age and weight
thresholds, or on the minimum
requirements of the law. We recommend
that you check with a NHTSA Certified
Child Passenger Safety Technician (CPST) to make sure that you properly
install the child restraint in your vehicle
and that you consult your pediatrician to
make sure you have a child restraint
appropriate for your child. To locate a
child restraint fitting station and CPST,
contact NHTSA toll free at
1-888-327-4236 or go to
www.nhtsa.dot.gov. In Canada, contact
Transport Canada toll free at
1-800-333-0371 or go to www.tc.gc.ca
to find a Child Car Seat Clinic in your
area. Failure to properly restrain children
in child restraints made especially for
their height, age and weight, may result
in an increased risk of serious injury or
death to your child.
WARNING:
On hot days, the
temperature inside the vehicle can rise
very quickly. Exposure of people or
animals to these high temperatures for
even a short time can cause death or
serious heat related injuries, including
brain damage. Small children are
particularly at risk.
