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

as well as the elimination of a convertible.
The automotive performance world soon
came to a screeching halt in the wake of
an oil embargo and resulting gas
shortages, forcing most Americans to
abandon their muscle cars and
V-8-powered rides in favor of smaller,
more fuel-efficient vehicles. Ford saw the
market shift as the perfect time to return
its pony car to its roots – a compact,
affordable, sporty car whose styling and
image captured the spirit and imagination
of the American public.
When the new-from-the-ground-up,
second-generation Mustang II was
launched for the 1974 model year, it was
the first Mustang equipped with a
four-cylinder engine. An all-new 2.3-liter
I-4 produced around 90 horses as the
standard powerplant for the downsized
Mustang II - yet performance was roughly
equivalent to the previous Mustang’
s big
inline six. The Mustang II was available as
a hardtop two-door notchback coupe or a
three-door hatchback-style fastback.
Buyers had a choice of either I-4 or V-6
power, as well as a three-speed automatic
or four-speed manual transmissions. To
keep Mustang’ s performance image going
even in a world where consumers favored
fuel economy over horsepower, an
enthusiast-focused Mustang II Mach 1
model was offered as a three-door
hatchback-style fastback, replete with
bucket seats.
There ’s little question that the saving grace
for the Mustang II’ s performance
reputation came when Ford finally realized
it needed to put the 302 V-8 back onto the
Mustang option list for 1975-78. The V-8
was available in any model, but first only
mated to a three-speed automatic
transmission, as a four-speed manual was
delayed a full year until a suitable clutch
could be tooled up. The two-barrel 302
shoehorned into the Mustang II got
catalytic converters to help meet 1976 ’s tighter emissions standards, and saw an
increase to 139 horsepower – nearly equal
to the ’
73’s standard V-8 power level. The
Mach 1’ s optional Competition Suspension
package offered stiffer springs, adjustable
shock absorbers and fatter front and rear
stabilizer bars to improve handling, and
kept it a popular enthusiast choice over all
five years of Mustang II's production. By
the dawn of the third-generation Mustang,
the Mach name would not return again to
the Mustang line until some 25 years later.
After the 1979-93 Fox Body Mustang years
had come and gone with the reintroduction
of a GT model, new sheet metal on a
revamped SN-95 platform helped to
rekindle consumer interest in a
fourth-generation Ford Mustang.
Enthusiasts lavished their attention upon
the 1993-1999 Mustang Cobra
performance model developed by the Ford
Special Vehicle Team skunkworks group,
while Ford engineers looked to specialty
models to fill the mid-market slot between
the standard Mustang GT and the
upmarket Cobra.
After the success of the 2001 Bullitt, a
new-for-2003 Mach 1 was launched to
offer fans some design cues from its '69
namesake, including a blackout hood,
black front air-dam extension and rear
decklid spoiler – even bodyside scoops. To
match its aggressive look and hardware
upgrades, the '03 Mach 1 was powered by
a 305-horsepower, 4.6L DOHC modular
V-8. Unlike the SVT Cobra, the Mach 1
offered an automatic transmission option
in lieu of the manual, and consequently
drew a new group of enthusiast buyers into
the Ford fold. The strong customer
response prompted another year of Mach
1 production for 2004, the Mustang's final
year on the fourth-gen platform.

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).

If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning (If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems. PRE-COLLISION ASSIST
(IF
EQUIPPED) 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 does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead
to a crash or personal injury. WARNING: The system may fail or
operate with reduced function during
cold and severe weather conditions.
Snow, ice, rain, spray and fog can
adversely affect the system. Keep the
front camera and radar free of snow and
ice. Failure to take care may result in the
loss of control of your vehicle, serious
personal injury or death. WARNING:
Some situations and
objects prevent hazard detection. For
