2003 FORD MUSTANG engine

STARTING
Positions of the ignition
1. ACCESSORY, allows
the electrical
accessories such as the
radio to operate while
the engine is not
running.
2. LOCK, locks the
steering wheel, automatic transmission gearshift
lever and allows key removal. For vehicle equipped
with a manual transmission, you must depress the
ignition release lever to release the key.
3. OFF, shuts off the engine and all accessories
without locking the steering wheel. This position
also allows the automatic transmission shift lever to
be moved from the P (Park) position without the
brake pedal being depressed.
In the ignition OFF position, the automatic
transmission shift lever can be moved from
the P (Park) position without the brake pedal
depressed. To avoid unwanted vehicle movement,
always set the parking brake.
4. ON, all electrical circuits operational. Warning
lights illuminated. Key position when driving.
5. START, cranks the engine. Release the key as
soon as the engine starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain
control system. This system meets all Canadian
Interference-Causing Equipment standard
requirements regulating the impulse electrical field
strength of radio noise.
When starting a fuel-injected engine, avoid pressing
the accelerator before or during starting. Only use

the accelerator when you have difficulty starting the
engine. For more information on starting the vehicle,
refer toStarting the enginein this chapter.
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the risk of
fire or other damage.
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine compartment
and exhaust system, which can start a fire.
Do not start your vehicle in a closed garage
or in other enclosed areas. Exhaust fumes
can be toxic. Always open the garage door before
you start the engine. SeeGuarding against
exhaust fumesin this chapter for more
instructions.
If you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you smell
exhaust fumes.
Important safety precautions
A computer system controls the engine’sidle
revolutions per minute (RPM). When the engine
starts, the idle RPM runs higher than normal in
order to warm the engine. If the engine idle speed
does not slow down automatically, have the vehicle
checked. Do not allow the vehicle to idle for more
than 10 minutes at high engine RPM.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled
their safety belts. For more information on safety
belts and their proper usage, refer to theSeating
and safety restraintschapter.

Makesurethecorrespondinglights illuminate or
illuminate briefly. If a light fails to illuminate, have
the vehicle serviced.
•If the driver’s safety belt is fastened, the
light
may not illuminate.
Starting the engine
Note:Whenever you start your vehicle, release the
key as soon as the engine starts. Excessive cranking
could damage the starter.
1. Turn the key to 5
(START) without
pressing the
accelerator pedal and
release as soon as the
engine starts. The key
will return to 4 (ON).
2. If the temperature is
above–12°C (10°F) and the engine does not start
within five seconds on the first try, turn the key to
OFF, wait 10 seconds and try again. If the engine
does not start in two attempts, press the accelerator
all the way to the floor and hold. Turn the key to
the START position.

3. If the temperature is below -12°C (10°F) and
the engine does not start in 15 seconds on the first
try, turn the key OFF and wait 10 seconds and try
again. If the engine does not start in two attempts,
press the accelerator pedal all the way to floor and
hold. Turn the key to START position.
4. When the engine starts, release the key, then
release the accelerator pedal gradually as the engine
speeds up.
5. After idling for a few seconds, apply the brake,
shift into gear and drive.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant,
which improves starting, warms up the engine faster
and allows the heater-defroster system to respond
quickly. Use of an engine block heater is strongly
recommended if you live in a region where
temperatures reach -23°C (-10°F) or below.
For best results, plug the heater in at least three
hours before starting the vehicle. Using the heater
for longer than three hours will not harm the engine,
so the heater can be plugged in the night before
starting the vehicle.
To prevent electrical shock, do not use your
heater with ungrounded electrical systems
or two-pronged (cheater) adapters.
Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is
present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you ever smell exhaust fumes of any kind
inside your vehicle, have your dealer inspect
and fix your vehicle immediately. Do not drive if
you smell exhaust fumes. These fumes are harmful
and could kill you.
Driving
137

Have the exhaust and body ventilation systems
checked whenever:
•the vehicle is raised for service.
•the sound of the exhaust system changes.
•the vehicle has been damaged in a collision.
WARNING:Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals known to
the State of California to cause cancer and birth
defects or other reproductive harm. In addition,
certain fluids contained in vehicles and certain
products of component wear contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in
an open area for long periods of time, open the
windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped)
to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet
vents clear of snow, leaves and other debris.
BRAKES
Your service brakes are self-adjusting. Refer to the
scheduled maintenance guide for scheduled
maintenance.
Occasional brake noise is normal and often does not
indicate a performance concern with the vehicle’s
brake system. In normal operation, automotive brake
systems may emit occasional or intermittent squeal
or groan noises when the brakes are applied. Such
noises are usually heard during the first few brake
applications in the morning; however, they may be
heard at any time while braking and can be
aggravated by environmental conditions such as
Driving

To release the parking
brake, the brake handle
may need to be pulled
up slightly to release
pressure before
pushing in the button.
Push the button on the
end of the parking
brake handle and push the handle down as far as
possible. Driving with the parking brake applied will
cause the brakes to wear out quickly and reduce fuel
economy.
Anti-lock brake system (ABS)
On vehicles equipped with an anti-lock braking
system (ABS), a noise from the hydraulic pump
motor and pulsation in the pedal may be observed
during ABS braking events. Pedal pulsation coupled
with noise while braking under panic conditions or
on loose gravel, bumps, wet or snowy roads is
normal and indicates proper functioning of the
vehicle’s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to
drive away. A brief mechanical noise may be heard
during this test. This is normal. If a malfunction is
found, the ABS warning light will come on. If the
vehicle has continuous vibration or shudder in the
steering wheel while braking, the vehicle should be
inspected by a qualified service technician.
The ABS operates by
detecting the onset of
wheel lockup during
brake applications and
compensates for this
tendency. The wheels
are prevented from
locking even when the brakes are firmly applied. The
accompanying illustration depicts the advantage of
an ABS equipped vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with
loss of front braking traction.
Driving

through the booster may be heard whenever the
brake is applied. This condition is normal. Vehicle
service is not required.
If braking performance or pedal response becomes
very poor, even when the pedal is strongly
depressed, it may indicate the presence of air in the
hydraulic system or leakage of fluid. Stop the vehicle
safely as soon as possible and seek service
immediately.
STEERING
Your vehicle is equipped with power steering. Power
steering uses energy from the engine to decrease
the driver’s effort in steering the vehicle.
To prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme
right or the extreme left for more than a few
seconds when the engine is running.
•Do not operate the vehicle with the power
steering pump fluid level below the MIN mark on
the reservoir.
If the power steering system breaks down (or if the
engine is turned off), you can steer the vehicle
manually, but it takes more effort.
If the steering wanders or pulls, the condition could
be caused by any of the following:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components
TRACTION CONTROL
Your vehicle may be equipped with the optional
Traction Control
system. This system helps you
maintain the stability and steerability of your
vehicle. It is especially useful on slippery road
Driving
142

surfaces.The system operates by detecting and
controlling wheel spin. The system borrows many of
the electronic and mechanical elements already
present in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to
be detected by the Traction Control
portion of the
ABS computer. Any excessive wheel spin is
controlled by automatically applying and releasing
the rear brakes in conjunction with engine torque
reductions. Engine torque reduction is realized via
the fully electronic spark and fuel injection systems.
This process is very sensitive to driving conditions
and very fast acting. The rear wheels“search”for
optimum traction several times a second and
adjustments are made accordingly.
The Traction Control
system will allow your
vehicle to make better use of available traction on
slippery surfaces. The system is a driver aid which
makes your vehicle easier to handle primarily on
snow, ice covered and gravel roads.
During Traction
Control
operation,
the traction control
active light will
illuminate, you may hear an electric motor type of
sound coming from the engine compartment and the
engine will not“rev-up”when you push further on
the accelerator. This is normal system behavior.
The Traction Control

on/off switch, located
below the radio,
illuminates when the
system is OFF. The
Traction Control
system will revert to the ON
position every time the ignition is turned OFF and
ON.
If you should become stuck in snow or ice or on a
very slippery road surface, try switching the Traction
Control
system off. This may allow excess wheel
spin to“dig”the vehicle out and enable a successful
“rocking”maneuver.
