A driver’s first responsibility is the safe
operation of the vehicle. The most important
thing you can do to prevent a crash is to avoid
distractions and pay attention to the road. Wait
until it is safe to operate Mobile Communications
Equipment.
POSITIVE RETENTION FLOOR MAT
(IF EQUIPPED)
Position the floor mat so
that the eyelet is over the
pointed end of the
retention post and rotate
forward to lock in. Make
sure that the mat does not
interfere with the operation
of the accelerator or the
brake pedal. To remove the
floor mat, reverse the installation procedure.
INTERIOR TRUNK CONTROL
The remote trunk release control is located in the
glove compartment. Press to open trunk.
CONVERTIBLE (IF EQUIPPED)
Do not store articles behind rear seat. Articles
stored in the convertible top stowage compartment
may break the rear glass window when the top is
lowered.
Lowering the convertible top
The convertible top can be lowered with the side
windows either up or down.
The convertible topwill not operateunless the
parking brake is engaged. Do not lower the top while
the vehicle is moving because the top may be
severely damaged. Also, do not lower the top when
the top material is wet.

•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may
also make the steering seem to wander/pull.
TRACTION CONTROL(IF EQUIPPED)
Your vehicle may be equipped with a Traction
Controlsystem. This system helps you maintain
the stability and steerability of your vehicle,
especially on slippery road surfaces such as snow- or
ice-covered roads and gravel roads. The system will
allow your vehicle to make better use of available
traction in these conditions.
During Traction
Controloperation,
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 and
should be no reason for concern.
The Traction Control
switch, located below
the radio, illuminates
when the system is off.
The Traction Control
system will
automatically turn on 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
Controlsystem off. This may allow excess wheel
spin to“dig”the vehicle out and enable a successful
“rocking”maneuver.
The traction control on/off status is shown by an
indicator lamp on the traction control switch. If the
2004 Mustang(mus)

system is off, the indicator will be illuminated. If a
system fault is detected while the traction control
system in on, the indicator lamp on the traction
control switch will be illuminated and your vehicle
should be serviced.
Aggressive driving in any road conditions
can cause you to lose control of your vehicle
increasing the risk of severe personal injury or
property damage. The occurrence of a Traction
Controlevent is an indication that at least some
of the tires have exceeded their ability to grip the
road; this may lead to an increased risk of loss of
vehicle control, vehicle rollover, personal injury
and death. If you experience a severe road event,
SLOW DOWN.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery
surfaces, particularly when one wheel is on a poor
traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
Extended use of other than the manufacturer’s
specified size tires on a Traction-Lok rear axle could
result in a permanent reduction in effectiveness.
This loss of effectiveness does not affect normal
driving and should not be noticeable to the driver.
AUTOMATIC TRANSMISSION OPERATION
(IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock
feature that prevents the gearshift lever from being
moved from P (Park) when the ignition is in the ON
position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P
(Park) with ignition in the ON position and the
brake pedal depressed:
1. Apply the parking brake, turn ignition key to
LOCK, then remove the key.

and is designed for emergency use only. Replace this
tire with a full-size tire as soon as possible.
Installing a tire on either or both sides of the driven
axle that is of a different size than the original road
tire is not recommended since this will affect the
accuracy of the speedometer and odometer. If
different size tires must be installed, it is important
that all four be the same size.
If one or more tires of the four are of a
different size, the ABS and traction control
system (if equipped) may not function correctly or
may not function at all. The temporary spare
supplied with the vehicle is the only different size
tire that should ever be installed.
If you use the temporary spare tire
continuously or do not follow these
precautions, the tire could fail, causing you to lose
control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tire do not:
• use more than one temporary spare tire at a time
• exceed 80 km/h (50 mph) or drive further than
3,200 km (2,000 miles) total under any
circumstances
• load the vehicle beyond maximum vehicle load
rating listed on the tire pressure label on the
driver’s side b-pillar
• tow a trailer
• use tire chains
• drive through an automatic car wash, because of
the vehicle’s reduced ground clearance
• try to repair the temporary spare tire or remove it
from its wheel
• use the wheel for any other type of vehicle
Use of a temporary spare tire at any one wheel
location can lead to impairment of the following:
