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.

If it flashes, engine misfire may be
occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Drive in a moderate fashion (avoid heavy
acceleration and deceleration) and have
your vehicle immediately serviced.
It illuminates when you switch the ignition
on prior to engine start to check the bulb
and to indicate whether your vehicle is
ready for Inspection and Maintenance
(I/M) testing.
Normally, it illuminates until the engine is
cranked and automatically turns off if no
malfunctions are present. However, if after
15 seconds it flashes eight times, this
indicates that your vehicle is not ready for
Inspection and Maintenance (I/M) testing.
See Catalytic Converter (page 161).
Shift Indicator
(If Equipped) Illuminates to inform you that
shifting to a higher gear as
indicated may give better fuel
economy and lower CO2
emissions. It will not illuminate during
periods of high acceleration, braking or
when you press the clutch pedal.
Stability Control and Traction
Control Indicator Flashes during operation.
If it does not illuminate when you
switch the ignition on, or remains
on when the engine is running, this
indicates a malfunction. Have your vehicle
checked as soon as possible.
Note: The system automatically turns off
if there is a malfunction.
See
Using Stability Control (page 176).
See Using Traction Control (page 174). Stability Control and Traction
Control Off Warning Lamp Illuminates when you switch the
system off.
Trunk Ajar Illuminates when the ignition is
on and the trunk is not
completely closed.
AUDIBLE WARNINGS AND
INDICATORS
Keyless Warning Alert
The horn sounds twice when you exit your
vehicle with the passive key and your
vehicle is in ON, indicating your vehicle is
still on. The horn also sounds twice when
you exit your vehicle and attempt to lock
the doors manually when the passive key
is still in the vehicle. The doors will not lock
if the passive key remains in the vehicle.
Headlamps On Warning Tone
Sounds when you remove the key from the
vehicle and you have left the headlamps
or parking lamps on.
Parking Brake On Warning Tone
Sounds when you have left the parking
brake on and drive your vehicle. If the
warning tone remains on after you release
the parking brake, have the system
checked by your authorized dealer
immediately.

CATALYTIC CONVERTER
WARNING: Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 234).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving. •
Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle ’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
