FORD MUSTANG 2003 4.G SVT Supplement Manual

4–WAY HEAD RESTRAINTS
Your vehicle’s seats are equipped with four-way
adjustable head restraints. The purpose of these
head restraints is to help limit head motion in the
event of a rear collision. To properly adjust your
head restraints, lift the head restraint so that it is
located directly behind your head or as close to that
position as possible. Refer to the following to raise
and lower the head restraints.
The head restraints can
be moved in four
directions:
•up and down
•forward or backward
POWER LUMBAR, ADJUSTABLE BOLSTERS
AND SEAT ADJUSTMENT
Your driver seat is
equipped with 6 way
power seat adjustment,
power lumbar and power
adjustable bolster
controls. These features
allow the driver to adjust
the seat location, the
amount of lumbar
support and the fit of
the seat.

Lumbar and adjustable bolster controls
The lumbar and adjustable bolster controls are
located on the front right corner of the driver seat.
The power lumbar feature creates lower back
support for the driver and may be adjusted to
increase or decrease the support. The seat back and
seat cushion bolsters inflate or deflate, allowing the
driver to create a firmer or more loose fitting seat.
Before adjusting these features, ensure that the seat
is in the driving position, then:
1. Seat back bolsters—Press
to deflate
(decrease firmness), press
to inflate (increase
firmness).
2. Seat cushion bolsters—Press
to deflate
(decrease firmness), press
to inflate (increase
firmness).
3. Lumbar controls—Press
to inflate (increase
lumbar support), or
to deflate (decrease lumbar
support.)
For maximum ease of vehicle ingress/egress, the seat
cushion and seat back bolsters should be completely
deflated.

ENERGY MANAGEMENT FEATURE
•This vehicle has a seat belt system with an energy
management feature at the front outboard seating
positions to help further reduce the risk of injury
in the event of a head-on collision.
•This seat belt system has a retractor assembly
that is designed to pay out webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the
occupant’s chest.
After any vehicle collision, the seat belt
system at all outboard seating positions
(except driver, which has no“automatic locking
retractor”feature) must be checked by a qualified
technician to verify that the“automatic locking
retractor”feature for child seats is still functioning
properly. In addition, all seat belts should be
checked for proper function.
BELT AND RETRACTOR ASSEMBLY MUST
BE REPLACED if the seat belt assembly
“automatic locking retractor”feature or any other
seat belt function is not operating properly when
checked.
Failure to replace the Belt and Retractor
assembly could increase the risk of injury in
collisions.

OCTANE RECOMMENDATIONS
Your vehicle is designed
to use“Premium”
unleaded gasoline with
an (R+M)/2 octane
rating of 91 or higher for optimum performance. The
use of gasolines with lower octane ratings may
degrade performance. We do not recommend the
use of gasolines labeled as“Premium”in high
altitude areas that are sold with octane ratings of
less than 91.
If your engine knocks under most driving conditions
while you are using fuel with the recommended
octane rating, see your dealer or a qualified service
technician to prevent any engine damage.
CHECKING ENGINE COOLANT
The concentration and level of engine coolant should
be checked at the mileage intervals listed in the
scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant
and water, which equates to a freeze point of -36°C
(-34°F). Coolant concentration testing is possible
with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester,
0014–R1060). The level of coolant should be
maintained at the“cold full”of“cold fill range”level
in the coolant reservoir. If the level falls below, add
coolant per the instructions in theAdding Engine
Coolantsection.
Your vehicle was factory-filled with a 50/50 engine
coolant and water concentration. If the
concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not
work properly.A50–50 mixture of coolant and
water provides the following:
•freeze protection down to -36°C (-34°F).
•boiling protection up to 129°C (265°F).
•protection against rust and other forms of
corrosion.

•an accurate temperature readout from the
engine coolant gauge.
When the engine is cold,
check the level of the
engine coolant in the
reservoir.
•The engine coolant should be at the“cold fill
level”as listed on the engine coolant reservoir.
•Refer to the scheduled maintenance guide for
service interval schedules.
•Be sure to read and understandPrecautions
when servicing your vehiclein this chapter.
If the engine coolant has not been checked at the
recommended interval, the engine coolant reservoir
may become low or empty. If the reservoir is low or
empty, add engine coolant to the reservoir. Refer to
Adding engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do
not use engine coolant, antifreeze or windshield
washer fluid outside of its specified function and
vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50
mixture of engine coolant and distilled water. Add
the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is
obtained.
Do not add engine coolant when the engine
is hot. Steam and scalding liquids released
from a hot cooling system can burn you badly.
Also, you can be burned if you spill coolant on hot
engine parts.
Maintenance

Do not put engine coolant in the windshield
washer fluid container. If sprayed on the
windshield, engine coolant could make it difficult
to see through the windshield.
The cooling system in your vehicle is filled with
either green-colored Motorcraft Premium Engine
Coolant meeting Ford specification ESE-M97B44–A
or yellow-colored Motorcraft Premium Gold Engine
Coolant meeting Ford Specification
WSS-M97B51–A1. To determine your vehicle’s
coolant type (color), check your coolant reservoir.
•Add Motorcraft Premium Engine Coolant
(green-colored), VC-4–A (U.S.) or CXC-10
(Canada) or Motorcraft Premium Gold
Engine Coolant (yellow-colored), VC-7–A,
depending on the type of coolant originally
equipped in your vehicle.If you are unsure
which type of coolant your vehicle requires, check
your coolant reservoir or contact your local
dealer.
•Do not add/mix an orange-colored, extended
life coolant such as Motorcraft Speciality
Orange Engine Coolant, VC-2 (US) or
CXC-209 (Canada), meeting Ford
specification WSS-M97B44–D with the
factory-filled coolant.Mixing Motorcraft
Speciality Orange Engine Coolant or any
orange-colored extended life product with your
factory filled coolant can result in degraded
corrosion protection.
•A large amount of water without engine coolant
may be added, in case of emergency, to reach a
vehicle service location. In this instance, the
cooling system must be drained and refilled with a
50/50 mixture of engine coolant and distilled
water as soon as possible. Water alone (without
engine coolant) can cause engine damage from
corrosion, overheating or freezing.
•Do not use alcohol, methanol or brine or any
engine coolants mixed with alcohol or
Maintenance

methanol antifreeze (coolant).Alcohol and
other liquids can cause engine damage from
overheating or freezing.
•Do not add extra inhibitors or additives to
the coolant.These can be harmful and
compromise the corrosion protection of the
engine coolant.
•Do not mix with recycled coolant unless from
a Ford-approved recycling process (seeUse of
Recycled Engine Coolantsection).
To avoid personal injury, make sure the
engine is cool before unscrewing the coolant
pressure relief cap. The cooling system is under
pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
If you must remove the pressure relief cap or
radiator cap (depending upon engine application),
follow these steps to avoid personal injury:
1. Before you remove the cap, turn the engine off
and let it cool.
2. When the engine is cool, wrap a thick cloth
around the cap. Slowly turn cap counterclockwise
until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been
released, use the cloth to turn it counterclockwise
and remove the cap.
Engine coolant refill procedure
The following procedure should be used when
refilling the cooling system after it has been drained
or become extremely low.
1. Remove the pressure relief cap from the engine
coolant reservoir as previously outlined.
2. Slowly add a50/50 mixtureof engine coolant
and distilled water to the engine coolant reservoir
until the coolant level is at the“cold fill level”as
listed on the reservoir.
Maintenance
19

3. Reinstall the pressure relief cap.
4. Start and idle the engine until the upper radiator
hose is warm (this indicates the thermostat is open
and coolant is flowing through the entire system).
5. Shut the engine off and let it cool.
6. Remove the pressure relief cap from the engine
coolant reservoir as previously outlined.
7. Add a50/50 mixtureof engine coolant and
distilled water to the engine coolant reservoir until
the coolant level is at the“cold fill level”as listed on
the reservoir.
8. Reinstall the pressure relief cap.
9. Check the coolant level in the reservoir before
you drive your vehicle the next few times (with the
engine cool).
10. If necessary, add a50/50 mixtureof engine
coolant and distilled water to the engine coolant
reservoir until the coolant level is at the“cold fill
level”as listed on the reservoir.
After any coolant has been added, check the coolant
concentration (refer toChecking Engine Coolant).
If the concentration is not 50/50 (protection to–34°
F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and
additions to obtain a 50/50 coolant concentration.
Whenever coolant has been added, the coolant level
in the coolant reservoir should be checked the next
few times you drive the vehicle. If necessary, add
enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper
level.
If you have to add more than 1.0 liter (1.0 quart) of
engine coolant per month, have your dealer check
the engine cooling system. Your cooling system may
have a leak. Operating an engine with a low level of
coolant can result in engine overheating and possible
engine damage.
